Description 3
3.1 Function
● The electropneumatic positioner and an actuator form a control system. The current position
of the actuator is recorded by a servo potentiometer and the actual value x is fed back. The
setpoint and the actual value are also shown simultaneously on the display.
● The control system provides the setpoint w digitally to the positioner over the bus.
● The positioner works as a predictive five-point positioner, through whose output value ±Δy
the integrated valves can be controlled by pulse length modulation.
● These input signals change pressure in the actuator chamber(s) and displace the actuator
until the control deviation becomes zero.
● Using the three buttons and the display with the enclosure cover removed, operation
(manual mode) and configuration (structuring, initialization, and parameter assignment) can
be performed.
● By default, the basic unit has a binary input (BIN). This binary input can be individually
configured and used, for example, to block the control levels.
● It has a friction clutch and a switchable gear so that the positioner can be used with different
mechanical part-turn and linear actuators.
● In the case of positioners with the "Fail in Place" function, the current position of the actuator
is held if the electric and/or pneumatic auxiliary power fails. Does not function in conjunction
with SIL.
3.2 Structure
3.2.1 Overview of structure
The following sections describe the mechanical and electrical structure, components, and
principle functionality of the positioner.
The positioner is used to move and control pneumatic actuators. The positioner works
electropneumatically, using compressed air as auxiliary power. The positioner is used to
control valves, for example, with:
● Linear actuator
● Part-turn actuator VDI/VDE 3845
Various add-on extensions are available for linear actuators:
● IEC 60534-6-1 (NAMUR)
● Integrated mounting on ARCA, except with flameproof stainless steel enclosure (6DR5..6)
● Integrated mounting on SAMSON, not for Ex d

3.4 Mode of operation
Control loop
The electropneumatic positioner forms a control loop with the pneumatic actuator:
● The actual value x represents the position of the actuator spindle for linear actuators or the
position of the actuator shaft for part-turn actuators.
● The higher-level control loop provides the setpoint w.
The stroke or rotary movement of the actuator is transferred to a potentiometer using suitable
attachments, positioner shaft and a backlash-free, switchable gear drive, and then to the
analog input of the microcontroller.
The current position can also be forwarded to the positioner using an external sensor. A Non-
Contacting Position Sensor (NCS) is used to record the stroke or rotary angle directly on the
actuator.
The microcontroller:
● Corrects the angle error of the shaft pick-up if necessary.
● Compares the potentiometer voltage as actual value x with setpoint w.
● Calculates the manipulated variable increments ±∆y.
The piezo-controlled inlet or exhaust air valve is opened depending on the magnitude and
direction of the control deviation (x-w). The actuator volume integrates the controller increment
for the actuating pressure y which is proportional to the drive rod or the drive shaft. This
controller increment changes the actuating pressure until the control deviation becomes zero.
Pneumatic actuators are available in single and double-acting versions. In a single-acting
version, only one pressure chamber is ventilated and depressurized. The pressure developed
works against a spring. In a double-acting version, two pressure chambers work against each
other. Ventilating the volume of one chamber simultaneously depressurizes the volume of the
other.
Control algorithm
The control algorithm is an adaptive, predictive five-point controller.
In case of large control deviations, the valves are controlled using permanent contact. This
takes place in the so-called fast step zone.
In case of medium control deviations, valves are controlled using pulse-length modulated
pulses. This takes place in the so-called slow step zone.

Small control deviations do not send control pulses in the zone. This takes place in the so-called
adaptive deadband. The deadband adaptation and the continuous adaptation of minimum
pulse lengths in "Automatic" mode ensure the best possible control accuracy with the smallest
number of operating cycles. The start parameters are determined during the initialization phase
and stored in the non-volatile memory. The most important start parameters are:
● The real actuator travel with end positions
● Travel times
● The deadband size
The number of fault messages, changes in direction, and the number of total strokes are
continuously determined during operation and saved every 15 minutes. You can read and
document these parameters using communication programs such as SIMATIC PDM and AMS.
By comparing the old values with the current ones, you can draw conclusions about the wear
and tear of the valve. You can use the diagnostics function for this.

4.4 Setting and locking the transmission ratio
Introduction
The positioner has a friction clutch and a transmission ratio selector. The positioner can
therefore be used on a variety of mechanically different part-turn and linear actuators.
● The transmission ratio selector allows you to adapt the positioner to small or large strokes.
● You can then use the friction clutch to adjust the working area.
Strong acceleration forces act on control valves that are subjected to heavy mechanical loads,
e.g. breakaway valves, strongly shaking or vibrating valves, as well as in case of "vapor
shocks". These forces may be much higher than the specified data. This may move the
transmission ratio in extreme cases. In these cases it is possible to lock the transmission ratio
selector by means of the gear fixing.

4.4 Setting and locking the transmission ratio
SIPART PS2 with 4 to 20 mA/HART
Operating Instructions, 01/2019, A5E00074631-AD 47
When the positioner is mounted and fully operational, set the friction clutch as described under
"Setting the friction clutch (Page 113)" in the section "Commissioning (Page 103)".
NOTICE
Wrong registration of the rotary or part-turn movement
A different setting of the transmission ratio selector and the gear latch results in a hysteresis
in position registration. The hysteresis in position registration can result in unstable control
response of the higher level control loop.
● Make sure the transmission ratio selector ⑤ and the gear latch ① are set to the same
value, either to 33° or to 90°.
Note
Use of external NCS sensor / internal NCS module
If you use the accessory part "NCS sensor for contactless position measurement" or a built-in
internal NCS module, the locking and fixing measures described in this section are not
necessary.
Requirement
● The positioner is mounted.
● You know whether the transmission ratio is to be set to 33° or 90°.

4.5.3 Alarm module 6DR4004-6A/-8A
Function
The alarm module triggers fault messages and alarms via three binary outputs. The message
function is based on the change in the signal status:
● If the signal status is "HIGH", there is no alarm message and the binary inputs are
conductive.
● If the signal status is "LOW", the module reports an alarm by shutting down binary outputs
using a high-resistance.
● Operational faults are signaled at a high-resistance output. Set the following parameters to
activate and configure the output of alarms and fault messages:
– "AFCT" - Alarm function
– "A1" - Response threshold, alarm 1
– "A2" - Response threshold, alarm 2
– "FCT" - Function for fault message output
– "TIM" - Monitoring time
– "LIM" - Response threshold
Apart from binary outputs, the alarm module has a binary input BIN2. Depending on the
selected parameters, this binary input is used to block the actuator or to move it to its end
position. Configure the suitable settings on parameter "BIN2".

5.3.4 Reaction to failure of auxiliary powers
Overview
The following overview diagram shows the pneumatic connection versions for different actuator
types, regulating action and safety position after an auxiliary power supply failure.
CAUTION
Before working on the control valve
Note that before working on the control valve, you must first move it to the safety position.
Make sure that the control valve has reached the safety position. If you only interrupt the
pneumatic auxiliary power supply to the positioner, the safety position may in some cases only
be attained after a certain delay period.
The difference between a failure of auxiliary pneumatic power and a failure of electrical auxiliary
power:
● Failure of electrical auxiliary power means:
– Device version 2-wire: Failure of signal source 4 to 20 mA
– Device version 3-wire/4-wire: Failure of power source 18 to 30 V
● Failure of auxiliary pneumatic power means the supply air PZ is interrupted.
With 3-wire/4-wire device version, the position 0% is approached if the signal source 0/4 to 20
mA fails.

Note
Failure of electrical auxiliary power
If electrical auxiliary power supply fails when configuring, the positioner responds as follows
when the power supply is reestablished:
● The positioner switches to the first parameter.
● Settings of the values already configured are retained.
In order to save the changed parameter values, exit the "Configuration" mode or switch to
another parameter. When "Configuration" mode is restarted, the output in the display switches
to the last activated parameter.
Manual mode (MAN)
In this mode, you move the actuator with or . The setting selected here is retained

6.2.5 Optimization of controller data
Note
Initializing
Initialize the positioner automatically before changing the parameter settings as per your
specific requirements.
The positioner determines the data for control quality automatically during the initialization
process.
The data determined is optimized for a short transient time in the case of minor overshoots.
The adjustment can be accelerated or the attenuation can be intensified by optimizing the data.
The following special cases are suitable for targeted data optimization:
● Small actuators with travel times < 1 s.
● Operation with boosters, described in section "Booster commissioning (Page 305)"
Procedure
1. Switch to "Diagnostics" mode.
2. Select the diagnostics parameters.

3. Press the three buttons of the positioner at the same time for at least 2 seconds.
4. Activate the setting function. Press the or button for at least 5 seconds.
The modified diagnostics values are effective immediately. The effects on the controller results
can then be tested.
In order to optimize the controller data, change the values of the diagnostics parameters listed
below.
Diagnostics parameters '23.IMPUP' Impulse length UP / '24.IMPDN' Impulse length DOWN
You can use these diagnostics parameters to determine the smallest impulse lengths for each
actuating direction. The actuator is then moved with these lengths. The optimum value
depends in particular on the volume of the actuator. Small values lead to small controller
increments and frequent activation of the actuator. Large values are advantageous for large
actuator volumes.
Note
Controller increments
● There is no movement if the values are too small.
● Large controller increments also lead to large movements with small actuators.
Diagnostics parameters '28.SSUP' Slow step zone UP / '29.SSDN' Slow step zone DOWN
The slow step zone is the area of mean control deviation. For more information on the slow step
zone, refer to the section "Mode of operation (Page 28)".
Select small values to achieve high speeds of shifting even with small control deviations. Select
large values to reduce overshoots particularly in case of large changes in the setpoint.
NOTICE
Overshoots or too low speeds of shifting
Too small values can result in overshoots.
● Enter a higher value.
Too large values result in too slow speeds of shifting near the adjusted status.
● Enter a smaller value.

Diagnostics parameters '47.PRUP' Prediction UP / '48.PRDN' Prediction DOWN
These diagnostics parameters act as attenuation factors and are used to set the control
dynamics. Changes in the diagnostics values have the following results:
● Small values result in quick adjustments with overshoots.
● Large values result in slow adjustments without overshoots.
Note
Reference variable
It is advantageous to use a fixed reference variable to optimize the control data. Therefore,
change the deadband of the controller in the '34.DEBA' parameter from "Auto" to a fixed
value.

WARNING
Lever for position detection
Danger of crushing and shearing with mounting kits which use a lever for position detection.
During commissioning and ongoing operation, severing or squeezing of limbs could occur as
a result of the lever. Risk of injury when working on control valves due to the high operating
force of the pneumatic actuator.
● Do not reach into the range of motion of the lever following mounting of the positioner and
mounting kit.
WARNING
Improper commissioning in hazardous areas
Device failure or risk of explosion in hazardous areas.
● Do not commission the device until it has been mounted completely and connected in
accordance with the information in Technical data (Page 237).
● Before commissioning take the effect on other devices in the system into account.
WARNING
Loss of explosion protection
Risk of explosion in hazardous areas if the device is open or not properly closed.
● Close the device as described in Installing and mounting (Page 35).
WARNING
Opening device in energized state
Risk of explosion in hazardous areas
● Only open the device in a de-energized state.

WARNING
Water in compressed air line
Device damage and possibly loss of type of protection. The factory setting for the purging air
selector is "IN". In the "IN" position, water from the compressed air line may enter the device
from the pneumatics during initial commissioning.
● Before commissioning, make sure that no water is present in the compressed air line.
If you cannot be sure that there is no water in the compressed air line:
● Set the purging air selector to "OUT". In this way, you prevent water from the compressed
air line from penetrating the device.
● Only set the purging air selector to "IN" again when all water has been discharged from the
compressed air line.
CAUTION
Loss of type of protection
Damage to device if the enclosure is open or not properly closed. The type of protection
specified on the nameplate or in Technical data (Page 237) is no longer guaranteed.
● Make sure that the device is securely closed.
WARNING
Commissioning and operation with pending error
If an error message appears, correct operation in the process is no longer guaranteed.
● Check the gravity of the error.
● Correct the error.
● If the error still exists:
– Take the device out of operation.
– Prevent renewed commissioning.
CAUTION
Increased sound pressure level
Changes to the sound absorber of the positioner or the mounting of pneumatic components
or pneumatic options on the positioner can cause a sound pressure with a level of 80 dBA to
be exceeded.
● Wear suitable hearing protection to protect yourself against hearing damage.

7.1 Basic safety instructions
SIPART PS2 with 4 to 20 mA/HART
104 Operating Instructions, 01/2019, A5E00074631-AD
When operating the positioner with natural gas, you must follow and adhere to the following
safety notes:
WARNING
Operation with natural gas
1. Only positioners and option modules which are connected to power supplies with type of
protection "Intrinsic safety, protection level [ia]" may be operated with natural gas.
2. Do not operate the positioner with natural gas in closed spaces.
3. Natural gas is continuously blown off, depending on the model. Special care must therefore
be taken during maintenance activities near the positioner. Always ensure that the
immediate surroundings of the positioner are adequately ventilated.
The maximum values for ventilation are listed in section "Technical data for natural gas as
actuator medium (Page 247)".
4. The mechanical limit switch module must not be used when operating the positioner with
natural gas.
5. Depressurize the devices operated with natural gas adequately during maintenance
activities. Open the cover in an explosion-free atmosphere and depressurize the device for
at least two minutes.
Note
Quality of natural gas
Only use natural gas which is clean, dry and free from additives.
7.2 Overview
Note
● During the initialization process, the operating pressure must be at least one bar more than
that required to close or open the valve. However, the operating pressure should not be
greater than the maximum permissible operating pressure for the actuator.
General information about commissioning
1. After installing the positioner on a pneumatic actuator, you must supply electric and
pneumatic auxiliary power to it.
2. The positioner is in the "P manual mode" before initialization. At the same time, "NOINI"
blinks in the lower line of the display.
3. Position feedback: You can adjust the range of position detection using the friction clutch if
necessary.
4. Adjust the positioner as per the respective actuator with the help of the initialization process
and by setting the parameters. If required, use the "PRST" parameter to cancel the
adjustment of the positioner on the actuator. The positioner is again in the "P manual mode"
after this process.

7.2 Overview
SIPART PS2 with 4 to 20 mA/HART
Operating Instructions, 01/2019, A5E00074631-AD 105
Types of initialization
You can initialize the positioner as follows:
● Automatic initialization:
during automatic initialization, the positioner determines the following one after the other:
– The direction of action
– The actuator travel and angle of rotation
– The travel time of the actuator
The positioner also adjusts the control parameters as per the dynamic response of the actuator.
● Manual initialization:
the actuator travel and the angle of rotation of the actuator are set manually. The remaining
parameters are automatically determined. This function is useful for valves which are lined,
for example, with PTFE.
● Copying the initialization data when replacing a positioner:
the initialization data of a positioner can be read and copied into another positioner. A
defective device can thus be replaced without interrupting an ongoing process through
initialization.
You have to define a few parameters for the positioner before initialization. Owing to the preset
values, you cannot adjust further parameters for initialization.
You can use a suitably configured and activated binary input to protect the configured settings
against accidental adjustment.

2. Now move the actuator to the horizontal position of the lever.
3. A value between 'P48.0' and 'P52.0' is shown on the display.
4. If a value beyond this value range is shown on the display, you must move the friction clutch.
Move the friction clutch until a value between 'P48.0' and 'P52.0' is reached. The closer this
value is to 'P50.0', the more accurately the positioner determines the stroke travel.
Note
For device versions with flameproof enclosure
The inner friction clutch is fixed. Therefore, only move the outer friction clutch. This also
applies when using an internal NCS module.
The following applies to device versions without flameproof enclosure with internal NCS
module 6DR4004-5L.:
The inner friction clutch has no function. This means you should only adjust the adjustment
wheel of the magnet clamp; see section "Internal NCS module (iNCS) 6DR4004-5L/-5LE
(Page 66)". Requirement: The '1.YFCT' type of actuator (Page 145) parameter is set.

7.9 Device replacement
Introduction
Note
Initialization
The positioner can be replaced without having to interrupt ongoing processes. However,
copying and transferring of the initialization parameters only allows an approximate adjustment
of the positioner to your actuator. Following initialization, the positioner initially works with the
manually defined parameters.
● For this reason, an automatic or manual initialization should be carried out as soon as
possible.
Note
Deferred initialization
Initialize the new positioner as soon as possible. The following properties can be ensured only
after initializing:
● Optimum adjustment of the positioner as per the mechanical and dynamic properties of the
actuator.
● Non-deviating position of end stops
● Correctness of the maintenance data
There are two ways of replacing a positioner when the equipment is in operation, without having
to interrupt the process. The two options depend on whether your positioner has
communication.
First possibility - with communication
1. Read the initialization parameters from the previous positioner. Use the parameter
assignment tools suitable for this purpose.
2. Transfer the initialization parameters read in the parameterization software under Point 1
into the new positioner.
3. Fix the actuator at its current position mechanically or pneumatically. Use the locking
function of your mounting kit, if available.
4. Determine the actual position value. To do this, read the actual position value from the
display of the previous positioner. Note down the read value.
5. Dismount the previous positioner from the actuator.
6. Attach the lever arm of the previous positioner to the new positioner.
7. Mount the new positioner on the actuator.
8. Set the transmission ratio selector of the new positioner to the same position as that of the
previous positioner.
9. If the displayed actual position value differs from the noted value, correct the deviation by
moving the friction clutch.

10.The new positioner is ready for operation when the displayed and noted values match.
11.Release the fixing of the actuator.
Second possibility - without communication
1. Fix the actuator at its current position mechanically or pneumatically. Use the locking
function of your mounting kit, if available.
2. Determine the actual position value. To do this, read the actual position value on the display
of the previous positioner. Note down the read value.
Note
Electronics defect
If the positioner's electronics is defective, measure the actual position value with a ruler or
protractor at the actuator or valve. Convert the read value into %. Note down the converted
value.
3. Dismount the previous positioner from the actuator.
4. Attach the lever arm of the previous positioner to the new positioner.
5. To prevent interference with the ongoing process, initialize the new positioner on an
actuator with a similar stroke or swivel range. Attach the new positioner to this actuator.
Initialize the new positioner.
6. Then dismount the new, initialized positioner from this actuator.
7. Mount the new, initialized positioner on the fixed actuator.
8. If the displayed actual position value differs from the noted value, correct the deviation by
moving the friction clutch.
9. Use the buttons on the positioner to enter the parameters which deviate from the factory
setting, such as type of actuator or tight closing.
10.Change to the measured value view using the button, see section "Description of
operating modes (Page 97)".

Functional safety 8
8.1 Range of applications for functional safety
The positioner is suitable for use on valves that satisfy the special requirements in terms of
functional safety up to SIL 2 in accordance with IEC 61508 or IEC 61511. The 6DR5.1.-0....-....-
Z C20 versions are available for this.
These are single-acting positioners for mounting on pneumatic actuators with spring return.
The positioner automatically depressurizes the valve actuator on demand or in case of faults,
which thus switches the valve to the specified safety position.
This positioner meets the following requirement:
● Functional safety up to SIL 2 in accordance with IEC 61508 or IEC 61511 for safe venting
See also
Functional safety in process instrumentation (http://www.siemens.com/SIL)
8.2 Safety function
Depressurizing of the connected actuator is the safety function for the SIPART PS2 positioner.
The built-in spring brings the valve to the required safety position. Depending on the direction
of action of this spring, the valve is completely opened or closed.
The positioner starts the depressurizing process of the connected pneumatic actuator at the
latest 100 ms after the request. The progress of the depressurizing process depends on the
connections and properties of the pneumatic actuator.
This safety function can be triggered by:
● With 2-wire connection: a signal source with 0 mA.
● With 3/4-wire connection: a power supply source with 0 V.
The safety function is not affected by other device functions, particularly the microcontroller,
software and communication interface. With respect to this safety function, the positioner must
therefore be considered as a type A subsystem in accordance with EN 61508-2.
SIPART PS2 with 4 to 20 mA/HART
Operating Instructions, 01/2019, A5E00074631-AD 129
Situations in which it is not possible to depressurize the actuator on demand or in the case of
a fault represent a dangerous failure.
WARNING
Disregarding conditions for fulfilling the safety function
Disregard can result in a malfunction of the process plant or application, e.g. process pressure
too high, maximum level exceeded.
The mandatory settings and conditions are listed in sections "Settings (Page 132)" and
"Safety characteristics (Page 133)".
● These conditions must be met in order to fulfill the safety function.
The pneumatic block of the positioner pressurizes and depressurizes the actuator. The
pneumatic block contains two pilot valves. The characteristic service life of the pneumatic block
depends on the load. On average it is approx. 200 million switching cycles for each of the two
pilot valves with symmetrical load. The number of control procedures for the switching cycles
is called in the local display or via HART communication. For more details, see Diagnostic value
'42.VENT1' / '43.VENT2' (Page 212).
NOTICE
Freezing of the exhaust air outlets
When devices of the type 6DR5..0/1/2/3 are used, the exhaust air outlets ② may freeze. The
function of the device is impaired.

Figure 8-2 Safety-instrumented system in single-channel operation
The combination of transmitter, automation system and final controlling element forms a safety-
instrumented system that performs a safety function.
The transmitter generates a process-related measured value that is transferred to the
automation system. The automation system monitors this measured value. If the measured
value exceeds the range of the high or low limit, the automation system generates a shutdown
signal for the connected final controlling element, which switches the associated valve to the
specified safety position.
8.3 Safety Integrity Level (SIL)
The international standard IEC 61508 defines four discrete Safety Integrity Levels (SIL) from
SIL 1 to SIL 4. Each level corresponds to a range of probability for failure of a safety function.
Description
The following table shows the dependency of the SIL on the "average probability of dangerous
failures of a safety function of the entire safety-instrumented system" (PFDAVG). The table deals
with "Low demand mode", i.e. the safety function is required a maximum of once per year on
average.

3 10-4 ≤ PFDAVG < 10-3
2 10-3 ≤ PFDAVG < 10-2
1 10-2 ≤ PFDAVG < 10-1
The "average probability of dangerous failures of the entire safety-instrumented system"
(PFDAVG) is normally split between the following three components:

Checking the safety function
Prerequisite for checking the safety function
● Positioner is in operation.
● The actuator belonging to the positioner is not in the safety position.
Procedure
● On the positioner, switch the signal source to 0 mA or the power supply source to 0 V.
● Reduce the inlet pressure (PZ) to a third of the maximum supply pressure.
● Always carry out the validation of the safety function with positioner and valve under
operating conditions.

8.5 Safety characteristics
The safety characteristics necessary for use of the system are listed in the SIL declaration of
conformity. These values apply under the following conditions:
● The positioner is only used in applications with low demand rate for the "Low demand mode".
● The positioner is blocked against unwanted and unauthorized changes/operation.
● The signal source with 0 mA or the power supply source with 0 V for the SIPART PS2
positioner is generated by a safe system that fulfills SIL 2 for single-channel operation.
● The connected single-acting type actuator returns the valve to the safe end position by
spring force in the following scenarios:
– With a chamber pressure (Y1 connection) up to a third of the maximum available supply
air pressure (PZ connection)
● The air outlet does not contain any additional cross-sectional contractions leading to an
increased dynamic pressure. In particular, a silencer is only allowed if icing or other
contamination is ruled out.
● The restrictor in the Y1 circuit may not be completely closed during operation.
● The auxiliary pneumatic power is free of oil, water and dirt in line with:
DIN/ISO 8573-1, maximum class 3
● The average temperature viewed over a long period is 40 °C.
● Fault rates are calculated on the basis of a mean time to repair (MTTR) of 8 hours.
● In case of a fault, the pneumatic outlet of the positioner is depressurized. A spring in the
pneumatic actuator must move the valve to the pre-defined, safe end position.
● A dangerous failure of the positioner is a failure whereby the pressure outlet is not
depressurized or the safety position is not reached when the signal source is 0 mA or the
power supply source is 0 V.

Parameter assignment 9
9.1 Introduction to parameter assignment section
A positioner is responsible for controlling a valve and for monitoring the status of a valve. The
parameters described in this section are used to optimally adapt the positioner to the valve and
its application.
The parameters are divided into initialization parameters, application parameters, and the
extended diagnostics parameters.
● Initialization parameters 1 to 5 (Page 145): Describes die parameters which are relevant for
initial commissioning of the positioner on the valve. For example, you can start the
automatic initialization here.
● Application parameters 6 to 52 (Page 149): Describes die parameters with which the
positioner is adapted to the valve application, for example tight closing at the end stops.
● Advanced diagnostic parameters A to U (Page 166): Describes the diagnostics functions
which are provided by the positioner. These include monitoring of leakages as well as the
partial stroke test. Following activation of these functions, the positioner continuously
monitors the status of the valve. If you enter thresholds in the parameters of the diagnostics
functions, the positioner actively signals high or low violation of these thresholds. The
current monitoring state for these thresholds is displayed as a diagnostic value. For
additional details on diagnostics and diagnostic values, refer to the section Diagnostics
(Page 198).
The following configuration schematic shows the principle of operation of the parameters. This
is followed by a tabular overview of the parameters. Finally, the individual parameters and their
functionality are described.
Furthermore, the positioners with HART, PA and FF communication interface in combination
with a host system, e.g. SIMATIC PDM or HART communicator etc., offer the following
advantages:
● Offline tests such as full stroke test, step response test, multi-step response test and valve
performance test.
● Diagnostics cockpit which provides an overview of the state of positioner and valve.
● Logbook with time stamp for documentation of all events such as the violation of thresholds.
● Wizards which provide prompting through the relevant parameters during commissioning,
the partial stroke test as well as the offline test.

146 Operating Instructions, 01/2019, A5E00074631-AD
Additional information:
● The '3.YWAY' Range of stroke (Page 148) parameter is
displayed only for 'WAY', '-WAY', 'ncSLL' or '-ncLL'.
● turn/-turn: The '2.YAGL' Rated angle of rotation of feedback
(Page 147) parameter is automatically set to 90° and cannot be
changed.
● WAY/-WAY: The positioner compensates the non-linearity. The
non-linearity is caused by the transformation of the linear
movement of the linear actuator into the rotary movement of the
positioner shaft. For correct compensation see section
"Preparing linear actuators for commissioning (Page 114)".
Factory setting: WAY
9.4.1.2 '2.YAGL' Rated angle of rotation of feedback
Requirement: Transmission ratio selector and the value set in the '2.YAGL' pa‐
rameter match. Only then does the value shown on the display
match the actual position.
Possible settings: ● 33°
● 90°
Purpose: Use this parameter for a linear actuator. For a linear actuator, set an
angle of 33° or 90° depending on the range of stroke. The current
setting of the actuator is then measured more accurately. The fol‐
lowing is applicable:
● 33°: Strokes ≤ 20 mm
● 90°: Strokes 25 ... 35 mm
● 90°: Strokes > 40 ... 130 mm
Use the mounting kit:
● 6DR4004-8V for strokes up to 35 mm
● 6DR4004-8L for strokes greater than 35 up to 130 mm
'2.YAGL' can only be adjusted if '1.YFCT' is set to 'WAY'/'-WAY' or
'FWAY'/'-FWAY'.
With all other settings of '1.YFCT', an angle of 90° is automatically
set for '2.YAGL'.
Factory setting: 33°

50.0 | 60.0 | 70.0 | 90.0 | 110.0 | 130.0
Purpose: Use this parameter to display the determined stroke value in mm
when initialization of a linear actuator has been completed.
If you select the 'OFF' setting, the real stroke is not displayed after
initialization.
From the possible settings shown above, select the value which
corresponds to the range of stroke of your actuator in mm.
If the range of stroke of the actuator does not correspond to a pos‐
sible setting, use the next higher value. Use the value specified on
the nameplate of the actuator for this purpose.
'3.YWAY' is only displayed if '1.YFCT' is set to 'WAY'/'-WAY' or
'ncSLL'/'-ncLL'.

9.4.2.2 '7.SDIR' Setpoint direction
Possible settings: ● riSE
● FALL
Purpose: This parameter is used to set the setpoint direction. The setpoint
direction is used to reverse the direction of action of the setpoint.
● Rising (riSE): A higher value at the setpoint input results in
opening of the valve.
● Falling (FALL): A higher value at the setpoint input results in
closing of the valve.
The setpoint direction is primarily used for the split-range mode and
for single-acting actuators with the safety setting 'uP'.
Factory setting: riSE
9.4.2.3 '8.SPRA' Setpoint split range start / '9.SPRE' Setpoint split range start end
Adjustment range: 0.0 ... 100.0
Purpose: With these two parameters in combination with parameter "'7.SDIR'
Setpoint direction (Page 150)", you can limit the effective setpoint.
This allows split range tasks with the following characteristic curves
to be solved:
● rising/falling
● falling/rising
● falling/falling
● rising/rising

Possible settings: With "TSUP"
● Auto
● 0 ... 400
With "TSDO"
● 0 ... 400
Purpose: The setpoint ramp is effective in "Automatic" mode and limits the
speed of change of the effective setpoint. This parameter is used to
set the value in seconds. When switching over from "Manual" mode
to "Automatic" mode, the setpoint ramp is used to adjust the effective
setpoint to the setpoint of the positioner.
This smooth switching from "Manual" mode to "Automatic" mode
prevents pressure excess in long pipelines.
The parameter "TSUP = Auto" means the slower of the two actuating
times determined during initialization is used for the setpoint ramp.
Parameter value "TSDO" then has no effect.

Setpoint characteristic curves, standardization of manipulated variables, and tight closing
function
Input of the setpoint turning points is only possible if the "'12.SFCT' Setpoint function
(Page 152)" parameter is set to "FrEE". You can only enter one monotone rising characteristic
curve and two consecutive interpolation points must differ by at least 0.2%.
9.4.2.7 '34.DEBA' Deadband of closed-loop controller
Possible settings: ● Auto
● 0.1 ... 10.0
Purpose: This parameter is used with the "Auto" setting to adjust the dead‐
band in automatic mode continually and adaptively to the require‐
ments of the control loop. If a regulator oscillation is detected, then
the deadband is incrementally enlarged. The reverse adaptation
takes place using a time criterion.
The deadband is set using the values 0.1 to 10.0. The value is given
in percent. Control oscillations can then be suppressed. The smaller
the deadband, the better the control accuracy.
Factory setting: Auto

9.4.2.8 '35.YA' Start of manipulated variable limit / '36.YE' End of manipulated variable limit
Adjustment range: 0.0 ... 100.0
Purpose: These parameters are used to limit the mechanical actuator travel
from stop to stop to the configured values. The value is given in
percent. This allows the mechanical travel range of the actuator to
be limited to the effective flow, preventing integral saturation of the
controlling closed-loop controller.
See the figure in the description of the '37.YNRM' Standardization of
manipulated variable (Page 154) parameter.
'Dead angle' function
The dead angle is the angle range in which the process valve allows
no flow. The dead angle range starts at the lower endstop of the
valve, for example, and ends at the angle at which the medium be‐
gins to flow. Use this function if you want to use the entire signal
range for valve control (for example, 4 to 20 mA).
To now use the entire signal range for valve control (for example, of
ball and segment valves), set the low limit of the manipulated varia‐
ble (YA) to the percentage at which the medium begins to flow.
To display the new start value as 0%, set '37.YNRM' Standardization
of manipulated variable (Page 154) to 'FloW'.
Factory setting: When 'YA': 0.0 When 'YE': 100.0
Note
'YE' must always be set larger than 'YA'.
9.4.2.9 '37.YNRM' Standardization of manipulated variable
Possible settings: ● MPOS
● FLoW
Purpose: Use the '35.YA' Start of manipulated variable limit / '36.YE' End of
manipulated variable limit (Page 154) parameters to limit the ma‐
nipulated variable. This limitation causes two different scaling types
'MPOS' and 'FLoW' for the display and for the position feedback
through the current output.
The MPOS scale shows the mechanical positions from 0 to 100%
between the upper and lower endstops of the initialization. The po‐
sition is not influenced by the '35.YA' Start of manipulated variable
limit / '36.YE' End of manipulated variable limit (Page 154) parame‐
ters. The 'YA' and 'YE' parameters are shown in the MPOS scale.

The FLoW scale is the standardization from 0 to 100% in the range
between the 'YA' and 'YE' parameters. Over this range, the setpoint
w is also always 0 to 100%. This results in a more or less flow-pro‐
portional display and position feedback. The flow-proportional dis‐
play and position feedback also results from the use of valve char‐
acteristics.
In order to calculate the control deviation, the setpoint in the display
is also shown in the corresponding scale.
The following uses the example of an 80-mm linear actuator to illus‐
trate the dependence of the stroke on the scaling as well as on the
'YA' and 'YE' parameters; see the following figure.

Note
Activated tight closing/fast closing function
If the function is activated, then the monitoring of control deviation is turned off in the respective
overflow direction for the '49. LIM' parameter. The following applies: 'YCDO: < 0 %' and
'YCUP: > 100 %'. This functionality is especially advantageous for valves with lining. For long-
term monitoring of the end positions, we recommend that you activate the 'F. ZERO' and 'G.

Purpose: Use the 'YCDO' parameter to set the value as of which the "Tight
closing/fast closing Down" function is activated. If the effective set‐
point is at or below the value set here, the actuator moves in tight
closing Down or fast closing Down.
Factory setting: 0.5
Note
The value in the 'YCDO' parameter is always smaller than that in 'YCUP'. The tight closing/fast
closing function has a fixed hysteresis of 1%. The 'YCDO' parameter is relative to the
mechanical stops. The 'YCDO' is independent of the values set in the '7.SDIR' Setpoint

● BIN1 or BIN2 = On or -On
Binary messages from peripherals, e.g. from pressure or
temperature switches, are read over the communication
interface or fed through a logical OR combination with other
messages to trigger the error message output.
● BIN1 = bLoc1
Use this parameter value to interlock the "Configuration" mode
against adjustment. The lock is performed e.g. with a jumper
between terminals 9 and 10.
● BIN1 = bLoc2
If binary input 1 has been activated, the "Manual" as well as
"Configuration" modes are blocked.

● BIN1 or BIN2 =
contact uP or doWn closes, or
contact -uP or -doWn opens
If the binary input is activated, the actuator uses the value defined
by the "'35.YA' Start of manipulated variable limit / '36.YE' End of
manipulated variable limit (Page 154)" parameter for controlling
in "Automatic" mode.
● BIN1 or BIN2 contact closes = StoP or -StoP contact opens
In "Automatic" mode, the piezo valves are blocked when the
binary input is activated. The actuator remains at the last
position. Leakage measurements can be performed in this way
without using the initialization function.
● BIN1 or BIN2 = PSt or -PSt
Using binary inputs 1 or 2, a partial-stroke test can be triggered
by actuation of your choice of a normally closed or normally open
switch.
● BIN1 or BIN2 = OFF
No function
Special function of binary input 1: If binary input 1 is activated in
"P-manual mode" by means of a jumper between terminals 9 and
10, the firmware version is displayed when the button is
pressed.
If one of the above functions is activated simultaneously with the
"BIN1" and "BIN2" parameters, then: "Blocking" has priority over
"uP". "uP" has priority over "doWn". "doWn" has priority over "PST".

9.4.2.16 '45.A1' / '46.A2' Response threshold of alarm
Adjustment range: 0.0 ... 100.0
Purpose: These parameters are used to specify when an alarm should be
displayed. The response thresholds of the alarms (in percent) refer
to the MPOS scale in the '37.YNRM' Standardization of manipulated
variable (Page 154) parameter. The MPOS scale corresponds to the
mechanical travel.
Depending on the setting of the alarm function in the '44.AFCT'
Alarm function (Page 159) parameter, the alarm is triggered upon an
upward violation (Max) or downward violation (Min) of this response
threshold.
Factory setting: With 'A1': 10.0 With 'A2': 90.0
9.4.2.17 '47.\\FCT' Function for fault message output

● Slot initiator alarm module (SIA module)
● Mechanical limit switch module
Possible settings: Normal direction of action Inverted direction of action
●
● nA
● nAb
● -
● - nA
● - nAb
Purpose: The fault message in the form of monitoring of control deviation over
time can also be triggered due to the following events:
● Power failure
● Processor fault
● Actuator fault
● Valve fault
● Compressed air failure
● Threshold 3 message of extended diagnostics.
See parameter '52.XDIAG' Activating for extended diagnostics
(Page 165).
The fault message cannot be switched off, but it can be suppressed
(factory setting) when you exit 'Automatic' mode. Set the ' FCT' pa‐
rameter to ' nA' to also generate a fault message here.
You also have an option to "or" the fault message with the status of
the binary inputs. To do this, first set the '42.BIN1' / '43.BIN2' Func‐
tion binary input (Page 158) parameter to 'on' or '-on'. Subsequently
set the ' FCT' parameter to ' nAb'.

● 0 ... 100
Purpose: The '48. TIM' parameter is used to set the time in seconds within
which the positioner must have reached the regulated condition. The
corresponding response threshold is specified in the '49. LIM' pa‐
rameter.
When the configured time is exceeded, the fault message output is
set.
Factory setting: Auto
Note
Activated tight closing/fast closing function
If the function is activated, then the monitoring of control deviation is turned off in the respective
overflow direction for the '49. LIM' parameter. The following applies: 'YCDO: < 0 %' and
'YCUP: > 100 %'. This functionality is especially advantageous for valves with lining. For long-
term monitoring of the end positions, we recommend that you activate the 'F. ZERO' and 'G.
OPEN' parameters.
9.4.2.19 '49.\\LIM' Response threshold of fault message 'Control deviation'
Possible settings: ● Auto
● 0 ... 100
Purpose: This parameter is used to set a value for the permissible size of the
control deviation to trigger a fault message. The value is given in
percent.
If the '48. TIM' and '49. LIM' parameters are set to 'Auto', then the
fault message is set if the slow step zone is not reached within a
certain period of time. Within 5 to 95% of the actuator travel, this time
is twice the initialization travel time, and ten times the initialization
travel time outside of 10 to 90%.
Factory setting: Auto
Note

test. Extend the partial stroke test to give the higher-level control
loop a chance to react to the partial stroke test.
Factory setting: OFF
A6.RPRT - Ramp rate
Adjustment range: 0.1 ... 100.0
Purpose: Change the ramp rate to shorten or extend the duration of the partial
stroke test. The ramp rate refers to the total stroke of the control valve
and is set in % stroke per second (%/s). Smaller values extend the
duration, larger values shorten the duration of the partial stroke test.
Example: Setting "10.0" means that the partial stroke test is run with
10% stroke per second.

The reference stroke time corresponds to the controlled movement
from the start position to the target position.
If the positioner has already been initialized, the calculated average
travel time of the control valve is displayed as a reference value.
● NOINI: Positioner has not yet been initialized.
● (C)##.#: An average travel time of 1.2 seconds, for example, is
shown in the display as "C 1.2", whereby "C" stands for
'calculated'. The average travel time can be used as a reference
stroke time. However, it merely represents a rough guideline
value.
● FdIni: If the starting position cannot be approached or the stroke
target cannot be achieved, "FdIni" is displayed. "FdIni" stands for
"failed PST initialization".

Requirement: The '52.XDIAG' Activating for extended diagnostics (Page 165) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
Possible settings: ● OFF
● On
Purpose: This parameter allows you to monitor the dynamic control valve be‐
havior. The actual position course is compared with the expected
position course for this purpose. This comparison helps in drawing a
conclusion about the correct operational response of the control
valve. Monitoring is performed in three steps. To activate monitoring,
set the parameter to 'On'. Sub-parameters are displayed. Appropri‐
ately set the sub-parameters.

Parameter assignment
9.4 Description of parameters
SIPART PS2 with 4 to 20 mA/HART
Operating Instructions, 01/2019, A5E00074631-AD 173
Requirement: The '52.XDIAG' Activating for extended diagnostics (Page 165) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
Operating mode 'Automatic' (AUT) is set for the leakage compen‐
sation.
Possible settings: ● OFF
● On
Purpose: This parameter is used to activate leak monitoring and leakage
compensation. Leakages mainly occur in the actuator or in the pipe
installation. To activate monitoring or compensation, set the param‐
eter to 'On'. Sub-parameters are displayed. Appropriately set the
sub-parameters.
The leakage compensation compensates the leakage in control
phases with constant setpoint. The control quality is increased by
reducing or preventing the typical, periodic oscillations of leaky
valves. The leakage compensation compensates leakages up to 2%
of the positioner's air performance.
The two following diagnostics values indicate the length and period
of the current leakage compensation pulse:
Diagnostic value '57.LKPUL - Length of the leakage compensation
pulse' (Page 214), Diagnostic value '58.LKPER - Period of the leak‐
age compensation pulse' (Page 214)
The leak monitoring is carried out in three stages for all control pha‐
ses (dynamic and static setpoints).
The current value of the monitoring is displayed in Diagnostic value
'16.ONLK - Pneumatic leakage' (Page 207).
Factory setting: OFF
C1.LIMIT - Limit
Adjustment range: 0.1 ... 100.0
Purpose: Use this sub-parameter to set the limit of the leakage indicator in
percent. Set the limit in a range from '0.1' to '100.0'. If no leakage
exists, monitoring of the pneumatic leakage is automatically calibra‐
ted in such a way during the initialization (section Commissioning
(Page 103)) that the leakage indicator remains below the value 30.
A value above 30 means that a leakage exists. '30.0' is therefore an
advisable setting for the parameter. After a certain time this limit can
be varied slightly depending on the application.

174 Operating Instructions, 01/2019, A5E00074631-AD
To optimize the sensitivity of the monitoring of the pneumatic leak‐
age to your specific application, follow these steps:
1. After initializing the positioner automatically, use a calibration
device to initiate a ramp movement.
2. Conditions for the ramp movement:
– The ramp covers the normal operating range of the valve.
– The steepness of the ramp matches the dynamic
requirements of the corresponding application.
– The characteristic of the ramp corresponds to the
characteristic of the setpoint that actually occurs.
3. During the ramp movement, the Diagnostic value '16.ONLK -
Pneumatic leakage' (Page 207) provides information about the
actual values. Define the limit of the leakage indicator
accordingly.
The positioner triggers a message if the current value exceeds one
of the three thresholds. How to set the three thresholds is described
below.
Factory setting: 30.0

Requirement: The '52.XDIAG' Activating for extended diagnostics (Page 165) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
Possible settings: ● OFF
● On
Purpose: Use this parameter to continuously monitor the current stiction (slip‐
stick) of the control valve. If the parameter is activated, the positioner
detects the slipstick that may occur. Sudden changes in the valve
position, so-called slip jumps, indicate excessive stiction. Where slip
jumps are detected, the filtered step height is stored as a slipstick
value. If slip jumps no longer exist, the stiction (slipstick) is reduced
slowly. Monitoring is performed in three steps. To activate monitor‐
ing, set the parameter to 'On'. Sub-parameters are displayed. Ap‐
propriately set the sub-parameters.
The current value is displayed in Diagnostic value '17.STIC - Stiction
(slipstick)' (Page 207). The positioner triggers a message if the cur‐
rent value exceeds one of the thresholds.
Factory setting: OFF
Note
Incorrect interpretation in case of travel times below one second
If the travel times are less than one second, the positioner does not accurately differentiate
between a normal movement of the actuator and a sudden change. Therefore, increase the
travel time if required.

General procedure
1. Press all three buttons at the same time for at least 2 seconds. You are now in the
diagnostics display.
2. Use the button to select the next diagnostics value.
3. Press the button for at least 2 seconds in order to exit the diagnostics display.
How to show the diagnostics values in reverse order
Press the and buttons simultaneously.
How to set values to zero
Specific values can be set to zero by pressing the button for at least 5 seconds. The
diagnostics values which can be reset are listed in the table in section "Overview of diagnostics
values (Page 199)".
10.2.2 Saving the diagnostics values
The diagnostic values are written into a non-volatile memory every 15 minutes so that, in the
event of a power failure, only the diagnostic values of the previous 15 minutes are lost. The
values in the resettable parameters can be set to zero.
To do this, press the button for at least 5 seconds.
The diagnostic values which can be reset can be found in the table in section Overview of

10.2.4 Meaning of the diagnostics values
10.2.4.1 Diagnostic value '1.STRKS - Number of total strokes'
Display range: 0 ... 4.29E9
Purpose: In operation, the movements of the actuator are summed up and
displayed in this diagnostics parameter as the number of strokes.
Unit: 100% strokes, i.e. the path between 0 and 100% and back.
10.2.4.2 Diagnostic value '2.CHDIR - Number of changes in direction'
Display range: 0 ... 4.29E9
Purpose: Every change in direction of the actuator is noted in the controller
and added to the number of changes in direction.
10.2.4.3 Diagnostic value '3.\\CNT - Number of fault messages'
Display range: 0 ... 4.29E9
Purpose: Every fault is noted in the closed-loop controller with '3. CNT' and
added to the number of fault messages.
10.2.4.4 Diagnostic value '4.A1CNT - Number of alarms 1' / '5.A2CNT - Number of alarms 2'
Requirement: '44.AFCT' Alarm function (Page 159) parameter is activated.
Display range: 0 ... 4.29E9
Purpose: This value indicates how often the alarm has been triggered.

10.2.4.5 Diagnostic value '6.HOURS - Number of operating hours'
Display range: 0 ... 4.29E9
Purpose: The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner.
10.2.4.6 Diagnostic value '7.HOURR - Resettable operating hours counter'
Display range: 0 ... 4.29E9
Purpose: The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner. In contrast to Diagnostic
value '6.HOURS - Number of operating hours' (Page 202), this value
can be reset.
Description: In order to minimize the control valve wear resulting from a poor
control quality, it makes sense to optimize the positioner's parame‐
ters. You can recognize optimum parameter settings when the val‐
ues of the Diagnostic value '44.VEN1R' / '45.VEN2R' (Page 213) are
low. Low values mean that the switching frequency of the positioner
pneumatics is also low. In order to carry out a comparison with var‐
ious parameter settings, determine the number of switching cycles
per hour. To do this, use the values of the Diagnostic value
'44.VEN1R' / '45.VEN2R' (Page 213) and '7.HOURR'. These three
parameters can be reset to enable simpler determination of the val‐
ues.
10.2.4.7 Diagnostic value '8.WAY - Determined travel'
Requirement for
linear actuator:
The travel is set in the '3.YWAY' Range of stroke (Page 148) pa‐
rameter.
Display range: 0 ... 130
Purpose: This value in mm or ° specifies the travel determined during the
initialization.
10.2.4.8 Diagnostic value '9.TUP - Travel time up' / '10.TDOWN - Travel time down'
Display range: 0 ... 1000
Purpose: This value indicates the current UP or DOWN travel time in seconds
determined during the initialization.

10.2.4.9 Diagnostic value '11.LEAK - Leakage test'
Requirement The positioner is initialized and in manual mode (MAN).
Display range: ● -
● 0.0 ... 100.0
Purpose: You can use this diagnostics parameter to read the last test result or
start an offline leakage test with which you can detect leakages in the
actuator or in the pipe installation. Display is percent stroke per mi‐
nute referred to the total stroke. A test result originates from one of
the following options:
● Function '11.LEAK' has already been carried out.
● Leakage test was already carried out during initialization, see
procedure of RUN 3 in section Sequence of automatic
initialization (Page 107).
● 'Offline leakage test' function was already executed by a HOST
system.
"-" in the display can have the following causes:
● A leakage test has not yet been carried out.
● Resetting to the factory settings was carried out using
the '50.PRST' Preset (Page 163) > ALL parameter.
● Positioner is not initialized.
How to start the test
1. Move the actuator to the position at which you wish to start the
test.
2. In 'Diagnostics' mode, go to the '11.LEAK' diagnostic value as
described in section Display of diagnostics values (Page 198).
3. Start the function by pressing the button for at least 5 seconds.
Description: 'Strt' is output in the display. The function is started after 5 seconds.
'tESt' and the current position of the actuator (actual value) are then
displayed alternately for one minute.
After one minute, the display shows the difference in the actuator
position before and after the test. This means: the actuator position
has changed by the displayed value in one minute.

Requirement 2 -
change values
● The positioner is initialized and in manual mode (MAN) or
automatic mode (AUT).
● The current position of the actuator is within the range -10 to
+10% of the lower endstop (P0).
● The current position of the actuator is within the range 90 to 110%
of the upper endstop (P100).
Purpose 2:
Change values
You can use these two parameters to change the lower endstop (P0)
and the upper endstop (P100).
Since initialization is not usually carried out under process condi‐
tions, the values for the lower endstop (P0) and the upper endstop
(P100) may change when the process is started. These changes may
result from temperature changes with the associated thermal expan‐
sion of the material. If the Monitoring of lower endstop 'F.\\ZERO'
(Page 179) and Monitoring the upper endstop 'G.\\OPEN' (Page 180)
parameters are active, the thresholds set in these two parameters
can be exceeded as a result of thermal expansion. An error message
is output in the display.
The process-dependent thermal expansion may represent the nor‐
mal state in your application. You do not wish to receive an error
message as a result of this thermal expansion. Therefore reset the
'P0' and/or 'P100' parameters after the process-dependent thermal
expansion has had its complete effect on the control valve. The pro‐
cedure is described in the following.
Description: Procedure for manual mode (MAN)
1. Move the actuator to the desired position of the lower endstop
(upper endstop) using the and buttons.
2. Switch to diagnostics mode.
3. Go to diagnostic value 21.P0 (22.P100).
4. Apply the setting by pressing the button for at least 5 seconds.
After 5 seconds, '0.0' (with 22.P100: '100.0') is displayed. Result:
The lower endstop (upper endstop) now corresponds to the
current position of the actuator.
5. Switch to manual mode (MAN). Result: Values for the upper
endstop (lower endstop) have changed.
Procedure for automatic mode (AUT)
1. Check in the display whether the current position of the actuator
is at the desired position of the lower endstop (upper endstop).
2. Switch to diagnostics mode.
3. Go to diagnostic value 21.P0 (22.P100).
4. Apply the setting by pressing the button for at least 5 seconds.
After 5 seconds, '0.0' (with 22.P100: '100.0') is displayed. Result:

Display range: 0 ... 4.29E9
Purpose: Control procedures of the pilot valves in the pneumatic block of the
positioner are counted and displayed in this parameter.
Description: The pneumatic block of the positioner pressurizes and depressurizes
the actuator. The pneumatic block contains two pilot valves. The char‐
acteristic service life of the pneumatic block depends on the load. This
amounts on average to approx. 200 million switching cycles for each of
the two pilot valves with symmetrical load. The number of control pro‐
cedures for the switching cycles serves to assess the switching fre‐
quency of the pneumatic block.
Counting procedure for single-acting actuators:
● Pressurize => 42.VENT1
● Depressurize => 43.VENT2
Counting procedure for double-acting actuators:
● Pressurize (Y2) / Depressurize (Y1) => 42.VENT1

el' (Page 202) to Diagnostic value '11.LEAK - Leakage test'
(Page 203) and Diagnostic value '21.P0 - Potentiometer value of
lower endstop (0%)' / '22.P100 - Potentiometer value of upper end‐
stop (100%)' (Page 208) to Diagnostic value '28.SSUP - Slow step
zone up' / '29.SSDN - Slow step zone down' (Page 211) are saved
in the non-volatile memory as 'data of last maintenance'. This diag‐
nostics data contains selected values whose changes can give in‐
formation about mechanical wear and tear of the valve.
This function is normally operated through the PDM, menu com‐
mand 'Diagnostics-> Save maintenance information'. The data of
the last maintenance operation can be compared with the current
data using SIMATIC PDM.

10.2.4.33 Diagnostic value '49.WT00' ... '56.WT95' - Number of operating hours in the travel range
WT00 to WT95
Display range: 0 ... 4.29E9
Purpose: When the positioner is in "Automatic" mode, statistics are continu‐
ously maintained regarding the duration for which a valve or a flap is
operated in a particular section of the travel range. The entire travel
range is divided into 8 sections from 0 to 100 %. The positioner
records the current position continuously and increments the run‐
time meter assigned to the corresponding travel range every hour.
This helps in drawing conclusions about the past operating condi‐
tions and especially in assessing the control properties of the control
loop and the entire control valve.

10.3.2 Overview of online diagnostics
Online diagnostics means diagnostics during ongoing operation. During operation of the
positioner, a few important values and parameters are continually monitored. In configuration
mode, you can configure that monitoring so that the fault message output will be activated if, for
instance, a limit is exceeded.
Information about what events can activate the fault message output can be found in the table
in section "Overview of error codes (Page 216)".
This section contains particular information about the following situations:
● Possible causes of the fault message.
● Events which activate the fault message output or alarm outputs.
● Settings of parameters needed for event monitoring.
● Cancelling an error message
When the fault message output is triggered in "Automatic" or "Manual" mode, the display shows
which fault triggered the message. The two digits on the lower left show the corresponding error
code. If multiple triggers occur at the same time, they are displayed one after the other
cyclically. The device status, including all fault messages, can be called up using command
"#48" over HART.

10.3.4 Meaning of error codes
10.3.4.1 1 Remaining control deviation
The deviation between the setpoint and the actual value is continuously monitored in
"Automatic" mode. The fault message for a remaining control deviation is activated depending
on the setting of the application parameters " TIM" - monitoring time for setting the fault
messages - and " LIM" - response threshold for the fault message. The fault message is
cancelled as soon as the control deviation drops below the response threshold. This monitoring
function is always active.
10.3.4.2 2 Device not in "Automatic" mode
When the device is not in automatic mode, an error message is generated if the ' FCT'
parameter (function of fault message output) is set correctly. A warning is then sent to the
control system if the device was switched to manual or configuration mode on-site.
10.3.4.3 3 Binary input BIN1 or BIN2 active
If the binary input is activated, an error message is generated when the " FCT" parameter
(function of fault message output) and the "BIN1" parameter (function of binary input 1) are set
correctly. For example, it can be a switch to monitor the packing glands, a temperature switch
or a limit switch (e.g. for pressure).
Binary input 2 (in the optional alarm module) can be configured in a similar manner.
10.3.4.4 4 Monitoring the number of total strokes
The diagnostics value "1 STRKS" is constantly compared with the thresholds that are
determined from the "L1.LIMIT" to "L4.FACT3" parameters. If the thresholds are exceeded, the
fault message output or the alarm outputs respond depending on the mode of the extended
diagnostics. These two functions can be deactivated using the parameter setting "OFF" for
"L. STRK".
10.3.4.5 5 Monitoring the number of changes in direction
The diagnostics value "2 CHDIR" is constantly compared with the thresholds that are
determined from the "O1.LIMIT" to "O4.FACT3" parameters. If the thresholds are exceeded,
the fault message output or the alarm outputs respond depending on the mode of the extended
diagnostics. These two functions can be deactivated using the parameter setting "OFF" for
"O. DCHG".

10.3.4.6 6 Monitoring the lower endstop / 7 Monitoring the upper endstop
If the parameter "F. ZERO" is set to "ON", monitoring of the lower endstop is activated. This
function can be used to detect the errors in the valve seat. An overshot limit indicates the
possibility of deposits or foreign bodies in the valve seat. An undershot limit indicates probable
wear and tear of the valve seat or flow restrictor. Even a mechanical misalignment of the
position feedback can trigger this fault message.
Monitoring is always carried out whenever the valve is in the "tight closing/fast closing Down"
position. The current position is compared with the position that was determined as the lower
endstop at the time of initialization. Requirement: '39.YCLS' Tight closing/fast closing with
manipulated variable (Page 156) Parameter is set to one of the following values: 'do', 'uP do',
'Fd', 'Fu Fd'.
Example: A value of 3% is set. The position is normally adopted for "tight closing/fast closing
Down". A fault is reported if a value > 3% or < -3% is determined instead.
The fault message remains activated until either a subsequent monitoring remains within the
tolerance or a re-initialization process is executed. Even the deactivation of monitoring ("F.
ZERO"=OFF) may trigger an error message.
This monitoring function does not deliver any utilizable results if the end stops were not
determined automatically at the time of initialization, but the limits were set manually (manual
initialization, "5.INITM").
Similar diagnostics is carried out for the upper endstop. The "G. OPEN" parameter is used to
set the limit for this. Requirement: '39.YCLS' Tight closing/fast closing with manipulated
variable (Page 156) Parameter is set to one of the following values: 'uP', 'uP do', 'Fu', 'Fu Fd',
'uP Fd', 'Fu do
10.3.4.7 8 Monitoring deadband
If the deadband increases disproportionately when adjusting it automatically ("DEBA"=Auto
parameter), it indicates an error in the system (e.g. severely increased packing gland friction,
play in the position displacement sensor, leakage). A limit can therefore be entered for this
value ("E1.LEVL3", threshold for deadband monitoring). An error message output is activated
when this value is exceeded.
10.3.4.8 9 Partial stroke test
On the one hand, this fault message appears when a manual or cyclic partial stroke test is
initiated and the test cannot be started since the valve is not within the starting tolerance. On
the other hand, the fault message appears when one of the three thresholds of the partial stroke
test that are determined from the 'A9.PSTIN' reference stroke time multiplied by factors
'AA.FACT1', 'Ab.FACT2' and 'AC.FACT3' is violated. The severity of the fault message is
shown by the number of bars on the display. The severity of the fault message is simultaneously
displayed using the fault message output or alarm outputs depending on the mode of the
advanced diagnostics.

10.3.4.9 10 Monitoring of dynamic control valve behavior
The monitoring of the operational behavior responds when the actual valve position shifts from
a narrow corridor between the setpoint and the expected position course. In this case, the
deviation between the expected and actual position course is filtered, displayed and compared
with the configured thresholds that are determined from the "b2.LIMIT" limit multiplied by the
factors "b3.FACT1" to "b5.FACT3".
10.3.4.10 11 Monitoring/compensation of pneumatic leakage
This fault message appears if a leakage is present. For additional information, see Monitoring/
compensation of pneumatic leakage 'C.\\LEAK' (Page 173).
10.3.4.11 12 Monitoring of stiction (slipstick)
If the stiction of the control valve increases during operation or if an increasing number of
Slipjumps is detected, "d1.LIMIT" could be exceeded and result in this fault message.
10.3.4.12 13 Monitoring the lower limit temperature
This fault message appears when the lower limit temperature thresholds are undershot.
10.3.4.13 14 Monitoring the upper limit temperature
This fault message appears when the upper limit temperature thresholds are overshot.
10.3.4.14 15 Monitoring the position average value
This fault message appears when a position value calculated after the expiry of a comparison
interval deviates from the reference value by more than the configured thresholds.
10.3.4.15 16 Monitoring the plausibility of values for the partial stroke test
This error message is triggered if, when starting a partial stroke test, the plausibility check of the
"A1.STPOS", "A3.STRKH" and "A4.STRKD" parameters was not successful.
10.3.4.16 17 Monitoring the pressure sensors
If the pressure sensor module is activated and at least one connected pressure sensor is
defective, this fault message is displayed.
10.3.4.17 18 Monitoring low limit of supply pressure (PZLIM)
If the supply pressure is below the configured low limit (PZLIM), this alarm message is
displayed.

External position detection B
B.1 Introduction
WARNING
External position detection system
Versions with flameproof enclosures may not be operated with an external position detection
system with the same type of protection.
In some cases it makes sense to mount the position detection and the controller unit separately.
A separate mounting the case, for example, with continuous and strong vibrations, high or too
low ambient temperatures and nuclear radiation. A universal component is available for this
purpose. It is suitable for part-turn and linear actuators. You will require the following:
One of the following external position detection systems
● Article number C73451-A430-D78 made of polycarbonate or with article number
6DR4004-1ES made of aluminum consisting of:
– Positioner enclosure
– Integrated friction clutch
– Integrated potentiometer
– Various blanking plugs and seals
● An external position detection system with article number 6DR4004-2ES, 3ES or 4ES
comprising:
– Positioner enclosure
– Internal NCS module
– Various blanking plugs and seals
– Integrated SIA module (6DR4004-3ES) or GWK module (6DR4004-4ES)
● NCS sensor for contactless position detection 6DR4004-6N.../-8N.
● Potentiometers with 3 kΩ, 5 kΩ or 10 kΩ
● Position sensor with a signal range from 0 to 20 mA
● Position sensor with a signal range from 0 to 10 V
And a positioner
● Positioner in combination with EMC filter module 6DR5..0/1/2/3-0...2/3 or retrofitted as
accessory 6DR4004-6F/-8F.
– An EMC filter module as an accessory is provided in a set along with cable clamps and
M20 cable glands.

B.2 Non-Contacting Sensor
B.2.1 Principle of operation of NCS
The NCS contains a magnetic field sensor. This sensor changes its electrical resistance in
response to the immediate presence of a permanent magnet. The sensor has a high signal-to-
noise ratio to external magnetic fields due to the measurement method used.
The following figure shows the mode of operation with a rotating magnet.
①Magnet ③Resistance change
②Sensor ④Angle
Figure B-1 Relative resistance change depending on the angle of the magnet
The figure shows that a circular movement of the magnet generates a sinusoidal change of the
resistance. The mechanical stops of the fitting ensure that only one part (quadrant) of the
sinusoidal curve is used at any one time. The principle-related non-linearity of the curve is
corrected by means of software based on a curve that is stored in the positioner.
A linear movement of the magnet in the sensor range also generates a resistance change that
is used to identify the position. The following figure highlights the principle:
①Magnet ③Resistance change
②Sensor ④Angle
Figure B-2 Resistance change depending on the position of the magnet
Non-linearity is corrected automatically in the SIPART PS2 positioner by software.
The great advantage of this principle is the absence of wear. Moreover, vibration, dampness
and temperature only have a minor impact on the measurement result.

270 Operating Instructions, 01/2019, A5E00074631-AD
B.2.2 Mounting the NCS
Function
The positioner facilitates the separate installation of the position detection system. The stroke
or rotary angle is measured directly at the actuator by means of a non contacting sensor. It is
therefore possible to install the controller unit at some distance away, e.g. on a mounting pipe
or similar. The positioner is connected to the position detection system by means of an
electrical cable.
Such a separate installation is useful whenever the ambient conditions at the valve exceed the
specified positioner values.
The NCS consists of a molded sensor for fixed installation and a magnet. The magnet is
mounted to the spindle on linear actuators, or to the stub shaft on part-turn actuators. The
sensor housing is mounted onto the console on part-turn actuators and to the bracket on linear
actuators. The bracket can be a NAMUR type, or any other mounting bracket.
Auxiliary power is supplied to the NCS via the EMC filter module 6DR4004-6F and EMC-
compatibility is ensured at the same time.
EMC filter module ordering options:
● Installed in the positioner; see Catalog FI 01
● For retrofitting in the positioner; item number 6DR4004-6F. For information on retrofitting
the EMC filter module, refer to the positioner operating instructions, chapter "Installation/
Mounting".

Requirements
1. An EMC filter module in the positioner.
2. A non contacting sensor for part-turn actuators 6DR4004-.N.10 or 6DR4004-.N.40.
3. A part-turn actuator with interface to VDI/VDE 3845 and mounting console to VDI/
VDE 3845, or a part-turn actuator with manufacturer-specific interface.
NOTICE
Incorrect mounting
A clearance of 3 mm must be maintained between the magnet and the mounting console
in order to ensure correct measurement of the actuator position. The values transferred
may be incorrect if this clearance is not given.
● Maintain a clearance of 3 mm between the top edge of the magnet ④ and the top edge
of the mounting console ⑩.

Procedure for the part-turn actuator to VDI/VDE 3845
1. Slide the clamping table ⑨ onto the stub shaft of the part-turn actuator.
2. Mount the clamping table ⑨ to the stub shaft using a hex socket head screw ⑦ and
washer ⑧.
3. Depending on the material of the magnet holder, proceed as follows:
Magnet holder made of glass fiber reinforced
polyester
Magnet holder made of anodized aluminum
1. Insert the plastic washer ⑥ into the
magnet ④.
2. Fix the magnet ④ onto the clamping
table ⑨. The magnet ④ can now be rotated
easily on the clamping table ⑨.
3. Slide the tensioning ring ① over the
magnet ④. Make sure that the spring
elements ③ and the hook ⑤ on the
magnet ④ are lined up above one another
and that they engage. You will now have
more resistance when turning the tensioning
ring ① and magnet ④.
1. Place the magnet ④ onto the clamping
table ⑨.
2. Secure the magnet ④ to the clamping
table⑨ by connecting the two parts of the
tensioning ring ① to the two hex socket
head screws ②. The magnet ④ can now be
rotated easily on the clamping table ⑨.
3. Then tighten the two hex socket head
screws ②. The magnet ④ can then no
longer be rotated on the clamping table ⑨.
4. Screw the NCS ⑬ onto the mounting console ⑩ using the hexagon socket-head screw ⑫,
hex nut ⑪ and the washer ⑧.
5. Once the NCS ⑬ is mounted, the clearance of 3 mm between the top edge of the
magnet ④ and the top edge of the mounting console ⑩ is set automatically.
Procedure for part-turn actuators with manufacturer-specific interface
1. Steps 1 to 4 as above.
2. Set a clearance of 3 mm between the top edge of the magnet ④ and the top edge of the
mounting console ⑩. Extend the stub shaft accordingly, or insert washers underneath the
NCS housing ⑬.

Procedure
The NCS sensor is equipped with a shielded four-pole cable. Wire this cable to the positioner
as follows:
1. Feed the four-pole NCS cable ⑩ through the union nut and the cable gland. Note: The type
of cable gland depends on the positioner version.
2. Tighten the cable gland ⑨.
3. Terminate the four-pole NCS cable ⑩ in the EMC module of the positioner in accordance
with the wiring diagram.
4. Place the cable clamp ⑦ onto the outer insulation of the four-pole NCS cable ⑩.
5. Use the screw ⑧ to bond the cable shielding lug ⑫ and the cable clamp ⑦ to the ground
terminal of the positioner.
6. Grounding:
The rear steel panel of the NCS sensor is inevitably bonded to the ground potential of the
system when mounting on the console. This ground connection is only functional if there is
a low-impedance connection to ground potential of the system. Ensure this state by
measuring the ground resistance. If necessary, ensure proper grounding by means of an
additional cable from the NCS sensor to ground potential.
B.2.4 Commissioning of NCS
B.2.4.1 Prerequisites / default settings
1. Supply electrical and pneumatic auxiliary power to the SIPART PS2 positioner. The top row
of the display shows the current sensor voltage (0 to 100%), while the "NOINI" info flashes
in the bottom row. The pneumatic actuator does not move.
2. If the SIPART PS2 positioner has already been initialized, carry out a reset. Carry out the
reset of parameter group "Init" in the '50.PRST' Preset (Page 163) parameter.
3. Preset for part-turn actuators:
While the valve or flaps are closed, align the North pole of the magnet with the cable; "N" in
position ⑦ in "Figure B-4 Mounting on part-turn actuator with magnet holder made of glass
fiber reinforced polyester (left figure) or anodized aluminum (right figure) (Page 272)".
4. Monitor the display of the positioner while adjusting the actuator to its mechanical stops by
means of and at the positioner. Verify that the displayed values never exceed the
range from P2.0 to P98.0.
Note
This condition cannot be met with slipping flaps or linear actuators that exceed the
mechanical actuation limits.

B.3 External position detection system
B.3.1 Principle of operation of external position detection systems
The external position detection systems essentially consist of an enclosure and an internal
position detection system. The position is recorded by a potentiometer or an internal NCS
module, section "Principle of operation of NCS (Page 270)". The controller unit is separated
from the positioner.
Such a separate installation is useful whenever the ambient conditions at the valve exceed the
specified positioner values.
The external position detection system is secured to a console on rotary actuators and to a
mounting bracket on linear actuators, section "Mounting to linear actuator (Page 39)".
Auxiliary power is supplied to the external position detection system via the EMC filter module,
and EMC is ensured at the same time.

CAUTION
Increased sound pressure level
Changes to the sound absorber of the positioner or the mounting of pneumatic components
or pneumatic options on the positioner can cause a sound pressure with a level of 80 dBA to
be exceeded.
● Wear suitable hearing protection to protect yourself against hearing damage.
E.1 Booster introduction
In order to shorten the travel times, use a booster between the positioner and actuator. The
booster increases the air performance.
With single-acting positioners, use of the boosters 6DR4004-1RJ, -1RK, -1RP or -1RQ, you
connect to the air output Y1.
With double-acting positioners, use two of the boosters 6DR4004-2RJ, -2RK, -2RP or -2RQ
which you connect to the air outputs Y1 and Y2.
Note
SIPART PS2 double-acting
The booster changes the double-acting SIPART PS2-operation in the event of the loss of
supply air. The Integral Volume Booster or external Volume Booster is used to depressurize the
output pressure; the valve position cannot be determined in the event of loss of supply air. The
Integral Volume Booster does not have any effect on the operation of the positioner in the event
of the failure of the control signal or power supply. You can find more detailed information on
this in the SIPART PS2 manual.
SIPART PS2 with 4 to 20 mA/HART
Operating Instructions, 01/2019, A5E00074631-AD 295
E.2 Operating principle of booster
The input pressure from the positioner which acts on the effective surface of the upper
diaphragm, produces a force which counteracts the force of the outlet pressure acting on the
lower diaphragm at a ratio of 1:1. A change of the inlet pressure results in a difference so that
balance has to be restored by a pilot valve. This increase presses the diaphragm module down,
opens the pilot valve and releases supply air to the outlet until balance is restored. A decrease,
on the other hand, ensures that the diaphragm module is raised, which opens the outlet air seat
and lowers the outlet pressure such that it corresponds to the inlet pressure. These devices
have a stabilizing bypass needle valve, so that the inlet pressure can directly go to the output
in the event of small or gradual changes at the input. As the booster has a bypass, there is no
loss of accuracy and if the needle valve is set properly, the persistence stability can be retained.
The suitable setting of the needle valve depends on the size of the actuator. The larger the
actuator, the more the needle valve can be closed and its stability retained.

Procedure for booster commissioning
1. Check whether the restrictor(s) on the positioner are completely open. With a new
positioner, the restrictors are factory-set to open. The position of the restrictors is shown in
the figure in section Device components (Page 26).
2. Set '34.DEBA' Deadband of closed-loop controller (Page 153) to the largest value
permissible for your process. The largest value is usually 0.5.
3. Start the automatic initialization process as described under Commissioning (Page 103).
Booster
E.5 Booster commissioning
SIPART PS2 with 4 to 20 mA/HART

4. With RUN 3, the initialization is stopped for five seconds. During these five seconds, start
the function for setting the booster using the button.
A cycle is started which continuously determines the overshoots. The values 'oSuP' and
'oSdo' are shown alternately in the display. 'oSuP' and 'oSdo' represent the values of the
overshoot in % of the total stroke.
5. During the automatic initialization, adjust the booster bypass using the adjustment screw on
the booster. For single-acting actuators, there is one adjustment screw; there are two
adjustment screws for double-acting actuators. Observe the description of your booster.
If 'oCAY' is shown on the display, the overshoot is less than 3%.
Adjustment of the booster is sufficient. If you do not achieve the message 'oCAY' (<3%
overshoot), try instead to achieve as small a value as possible. Observe the travel time in
the process.
6. Press the or button. The positioner again runs through the initialization step RUN 3,
starting with determination of the travel times. The following figure schematically shows the
RUN 3 sequence for the booster.
7. 'FINISH' is shown on the display when the initialization has been completed.
If the process value on the display does not remain stable or if a constant manipulated variable
cannot be achieved for a constant setpoint, further optimization of the controller data is
necessary. This is described in section Optimization of controller data (Page 99).

Positioner with remote control electronics F
F.1 Introduction to remote control electronics
In some cases it is advisable to use the positioner separately from the control electronics. The
option of separating the control electronics of the positioner is available for this purpose. The
positioner is in a different location than the control electronics. This remote control electronics
of the positioner allows the valves to be controlled in radiation contaminated environment, as
all highly integrated electronic components are located in the area that is protected from
radiation. Highly integrated electronic components are, for example, memory blocks and
microprocessor blocks.
For the above described deployment you required the two following components:
● Component 1 consisting of the control electronics in the form of a 19" slide-in module. The
19" slide-in module is installed in the control cabinet and is available in the following two
versions:
– Slide-in module as 4 to 20 mA with 2-wire connection, article number A5E00151560
● Component 2 consisting of the positioner without control electronics. The positioner with
control electronics is mounted on the valve.
– Positioner without control electronics with position detection system and pneumatic unit,
mounted on the valve, article number 6DR5910-0NG00-0AA0.
Positioner without basic electronics 6DR5910 (Page 318)
Components 1 and 2 are connected electrically to each other. The components are described
below.

F.2.1 Description of 19" slide-in module 4 to 20 mA
Description
This component is a control electronics in the 19" slide-in module in 4 to 20 mA version.
Commissioning is only possible in conjunction with a positioner component 6DR5910. The 19"
slide-in module has three channels and controls up to three valves.
The control electronics supplies the current position of the valve in the form of a current of 4 to
20 mA, which corresponds to the position feedback.

An analog-to-digital converter is an interface between the analog environment and the digitally
working computers. Only then can the computers be used for measurement and control tasks.
Analog-to-digital converters convert analog input signals to digital signals. Analog
measurement data is thus converted into digital information. On the other hand, a digital-to-
analog converter coverts digital information into analog signals.

Degree of protection
The degree of protection of a device indicates the extent of protection. The extent of protection
includes the safety of persons against coming in contact with live or rotating parts, and the
protection of electric resources against the penetration of water, foreign bodies and dust. The
degrees of protection of electric machines are indicated by an abbreviation comprising two
letters and two numbers (e.g. IP55). The degree of protection is coded using the IP code. The
degrees of protection are standardized in DIN EN 60529.

Failure that causes a dangerous situation
Failure with the potential to switch a safety-instrumented system to a hazardous or non-
functioning safety status.
Firmware
Firmware (FW) is software that is embedded on a chip in electronic devices – in contrast to
software which is saved on hard disks, CD-ROMs or other media. These days, firmware is
mostly stored in a flash memory or an EEPROM. Firmware is software in the hardware, and is
thus an intermediate between software and hardware. Firmware is normally model-specific.
This means that it does not function on other device models and is delivered by the
manufacturing company. The corresponding devices cannot function without the firmware. The
firmware mostly contains elementary functions to control the device, as well as input and output
routines.
Frequency shift keying
ENGLISH: Frequency shift keying (FSK)
Frequency shift keying is a simple modulation format in which digital values 0 and 1 are
represented by two different frequencies.
GSD file
The file that describes the properties of a PROFIBUS DP slave or a PROFINET IO device.
The GSD file is a database file for PROFIBUS devices. The device manufacturer provides the
corresponding GSD file containing the description of device properties. The information in the
file can be read using Engineering Tools.
HART
HART (Highway Addressable Remote Transducer) is a standardized and widely used
communication system for configuring industrial fieldbuses. This communication system
enables digital communication of multiple participants (field devices) using a common data bus.
HART implements the widely used 4/20 mA standard to transfer analog sensor signals.
Existing cables of the old system can be used directly and both systems can be operated
simultaneously. HART specifies several protocol levels in the OSI model. HART enables
transfer of process and diagnostics information and control signals between field devices and
the higher-level control system. Standardized parameter sets can be used for manufacturer-
independent operation of all HART devices.

328 Operating Instructions, 01/2019, A5E00074631-AD
HART communication
HART devices use the 4 to 20 mA lines for data exchange, and communicate with each other
using the HART protocol. The process enables bidirectional data exchange even in hazardous
environments. With HART communication, digital data from an FSK modem is modulated to the
analog 4 to 20 mA signals. As a result, additional information such as measuring and/or device
data can be transmitted without influencing the analog signals. The FSK modem required for
this is installed in the field device or HART communicator. In the case of an operator station, the
connection is made externally via the serial interface. A point-to-point connection is used
between the field and HMI device. In this case, a HART HMI device is connected to exactly one
HART field device. However, further devices can be integrated using a multiplexer.
HART communicator
For parameter assignment with the HART Communicator, the connection is made directly to
the 2-wire cable. For parameter assignment with a laptop or a PC, a HART modem is connected
in between.
Increment
From the Latin word incrementare, increase. Increment is the defined amount of change when
increasing a variable gradually. IT term that refers to a step-by-step increase in a numeric
value.→Decrement.
Initialization
Setting the most important basic parameters. Requirement for commissioning the positioner.
IP code
The abbreviation IP stands for International Protection as per DIN. In English-speaking
countries, IP stands for Ingress Protection.
Microcontroller

NEMA
National Electrical Manufacturers Association. NEMA is a standardization institute in the USA.
NEMA was formed in 1926 with the merge of Associated Manufacturers of Electrical Supplies
and the Electric Power Club.
Parameter assignment
Individual parameter settings are specifically changed to adjust the positioner as per the
actuator or other requirements. Parameter assignment is carried out after the complete
commissioning of the positioner.
Piezoelectric effect
Name of a physical phenomenon. Due to mechanical compression loads on a crystal, an
electric potential develops on specific crystal surfaces. In a reverse case, applying an electric
field to specific crystal surfaces leads to crystal deformation.
Potentially explosive atmosphere
Mixture of air, combustible gases, fluff, fibers or dusts.
Pressure chamber
The pneumatic actuators are available in single and double-acting versions. In a single-acting
version, only one pressure chamber is pressurized and depressurized. The pressure
developed works against a spring. In a double-acting version, two pressure chambers work
against each other. Pressurizing the volume of one chamber simultaneously depressurizes the
volume of the other.
Process Device Manager
PDM is a Siemens software package for configuration, parameter assignment, commissioning
and maintenance of network configurations and field devices. Part of SIMATIC STEP 7. Used
for configuration and diagnostics.

Protocols
Protocols contain information about data formats, time sequences and error handling when
exchanging data between computers.
A protocol is a convention about establishing, monitoring and terminating a connection.
Different protocols are required for a data connection. Protocols can be assigned to every layer
of the reference model. Transport protocols are used for the lower four layers of the reference
model and higher protocols are used for control, data provision and application.
Safety function
Defined function executed by a safety-instrumented system with the objective of attaining or
maintaining a safe status of the system by taking a defined hazardous incident into account.
Example: limit pressure monitoring
Safety-instrumented system
A safety-instrumented system (SIS) executes safety functions that are required to attain or
maintain the safe status in a system. It consists of sensors, logic unit/control system and final
controlling elements.
Example: a safety-instrumented system consists of a pressure transmitter, a limit signal
indicator and a servo valve.
Sensor
Converter that converts mechanical or other non-electric variables into electric signals.
SIL
The international standard IEC 61508 defines four discrete safety integrity levels (SIL) from SIL
1 to SIL 4. Every level indicates a probability range for the failure of the safety function. The
higher the SIL of the safety-instrumented system, the higher the probability that the required
safety function works. The achievable SIL is determined by the following safety-instrumented
characteristics:
● Average probability of dangerous failures of a safety function on demand (PFDAVG)
● Hardware fault tolerance (HFT)
● Safe failure fraction (SFF)
