Output Assignments
Signals available as allocated outputs are the control output (heat),
control output (cool), alarm 1, alarm 2, alarm 3, LBA, and HBA. The
auxiliary outputs of the Digital Controller cannot be used as control
outputs.
Control output (heat), control output (cool) , alarm 1, alarm 2, alarm
3, LBA, error 1 (input error), error 2 (A/D converter error), and error 3
(RSP input error) output functions are available. These functions
are assigned to control outputs 1 and 2 and auxiliary outputs 1 and
2.
The assignment destination of each output function is may be re-
stricted. Refer to the following table.
Standard Models

Error 3: RSP input error --- --- Yes Yes
With control output (cool), the conditions for switching from
standard control to heating and cooling control are reached
when the output function is assigned at the cooling side during
heating and cooling control.
In other words, heating and cooling control is carried out when con-
trol output (cool) is assigned, and standard control is carried out
when output is not assigned.

LBA
The LBA (loop break alarm) function is available when it is assigned
as an output. The LBA function is not available when a memory or
A/D converter error results.
LBA is a function for determining that an error has occurred some-
where on the control loop and outputting an alarm when the process
value does not change with the manipulated variable at a maximum
or minimum state. Accordingly, the LBA function can be used as a
means for detecting a malfunctioning control loop.

Level 1 Mode The main mode for adjusting control. In this mode, execute A T (auto-tuning), and set alarm values,
the control period, and PID parameters.
Level 2 Mode The auxiliary mode for adjusting control. In this mode, set the parameters for limiting the manipulated
variable and set point, switch between the remote and local modes, switch between the SP mode,
and set the loop break alarm (LBA), alarm hysteresis, and the digital filter value of inputs.
Setup Mode The mode for setting the basic specifications. In this mode, set parameters that must be checked or
set before operation such as the input type, scaling, output assignments and direct/reverse opera-
tion.
Expansion Mode The mode for setting expanded functions. In this mode, set ST (self-tuning), SP setting limiter, select
advanced PID or ON/OFF control, specify the standby sequence resetting method, and set the time
for automatic return to the monitoring display.
Option Mode The mode for setting option functions. Select this mode only when the Option Unit is set in the Con-
troller . In this mode, set the communications conditions, transfer output and event input parameters
to match the type of Option Unit set in the Controller . Heater burnout latch function, position-propor-
tional travel time, and remote SP scaling parameter are also located in this mode.

Input Shift
When temperature input is selected, scaling is not required. This is
because input is treated as the “temperature” as it is matched to the
input type. However, note that the upper- and lower-limit values of
the sensor can be shifted. For example, if both the upper- and lower-
limit values are shifted by 1.2°C, the process value (before shift) is
regarded as 201.2°C after shift when input is 200°C before shift.
To set the input shift, set shift values in the “input shift upper limit”
and “input shift lower limit” parameters (level 2 mode).

How to Use the Error Display
When an error has occurred, the No.1 display alternately indicates error codes together with the current display item.
This section describes how to check error codes on the display, and the actions that must be taken to remedy the problem.
Input Error
Meaning Input is in error.
Action Check the wiring of inputs, disconnections, and shorts, and check the input type and the input type
jumper connector.
Operation at Error For control output functions, output the manipulated variable matched to the setting of the “MV at PV
error” parameter (level 2 mode). Alarm output functions are activated when the upper limit is exceed-
ed.
Memory Error
Meaning Internal memory operation is in error
Action First, turn the power OFF then back ON again. If the display remains the same, the E5AK/E5EK Con-
troller must be repaired. If the display is restored to normal, the probable cause may be external noise
affecting the control system. Check for external noise.
Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in
case of other outputs). Alarm output functions turn OFF.
A/D Converter Error
Meaning Internal circuits are in error.
Action First, turn the power OFF then back ON again. If the display remains the same, the E5AK/E5EK Con-
troller must be repaired. If the display is restored to normal, the probable cause may be external noise
affecting the control system. Check for external noise.
Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in
case of other outputs). Alarm output functions turn OFF.
Calibration Data Error
This error is output only during temperature input and is displayed for two seconds when the power is
turned ON.
Meaning Calibration data is in error.
Action Must repair.
Operation at Error Both control output functions and alarm output functions are active. However , note that the readout
accuracy is not assured.
Display Range Over
Meaning Though not an error, this is displayed when the process value exceeds the display range when the
control range (setting range ±10%) is larger than the display range (–1999 to 9999).
•When less than “–1999”
•When greater than “9999”
Operation Control continues, allowing normal operation.
E5AK E5AK
20
Motor Calibration Error (Displayed on the No. 2 Display)
Meaning Motor calibration has ended with an error.
Action First, correctly connect the wiring for the potentiometer, open output, and close output.
Execute the motor calibration again.
Operation Procedure
Operation at Error When motor calibration is executed, open output will operate and then close output will operate.
However, as the value is incorrect, the result turns out to be an error.
E5AK E5AK
21
Fuzzy Self-tuning
Fuzzy self-tuning is a function that enables the E5AK/E5EK to cal-
culate the most suitable PID constants for the controlled object.
Features
•The E5AK/E5EK determines by itself when to perform fuzzy
self-tuning.
Fuzzy Self-tuning Function
The fuzzy self-tuning function has three modes.
In SRT (step response tuning) mode, the PID constants are tuned
using a step response method at the time the set point is changed.
In DT (disturbance tuning) mode, the PID constants are amended
so that the controlled temperature will be within the target range
set in advance when there is external disturbance.
In HT (hunting tuning) mode, when hunting occurs, the PID
constants are amended to suppress the hunting.
Note: Be sure to turn on the power supply to the load either before
or simultaneously with the start of Temperature Controller
operation.
Dead time will be measured from the time the Temperature
Controller starts operating. If a load such as a heater is
turned on after the Temperature Controller is turned on,
dead time longer than the actual value will be measured
and inappropriate PID constants will be obtained. If an ex-
tremely large amount of dead time is measured, the control
amount will be set to 0% for a short period of time before
being returned to 100%, and the constants will then be re-
tuned. Retuning is performed only for large amounts of
dead time, so be sure to follow the precaution given above
when starting operation.
Startup Conditions of SRT
SRT will start if the following conditions are satisfied simultaneously
when the E5AK/E5EK is turned on or the set point is changed.
At the time the E5AK/E5EK
starts operating At the time set point is
changed
1. The set point at the time the
E5AK/E5EK starts operating
is different from the set point
used at the time SRT was last
executed (see note).
2. The process value at the time
the E5AK/E5EK starts operat-
ing is smaller than the set
point in reverse operation and
larger than the set point in
normal operation.
1. The new set point is
different from the set point
used at the time SRT was
last executed (see note).
2. The process value is in
stable condition before
the set point is changed.
3. A larger set point value is
set in reverse operation
and a smaller set point is
set in normal operation.
Note: The last SRT -executed set point is set to 0 before shipping
and when changing from advanced PID control to ad-
vanced PID control with fuzzy self-tuning.
PID Constant Refreshing Conditions
If the step control amount is applied before the maximum tempera-
ture slope (R) is obtained, SRT will not renew any PID constant. If
the proportional band obtained from the R and L values that were
measured before the imposition had been completed is larger than
the present proportional band, the PID constants will be renewed
because the measured value is in the direction towards the suitable
proportional band value, and the set point at that time will be the
SRT-executed set point.
Temperature Slope (R) Stable range
Time
SP
Stable Temperature Status
If the temperature is within the stable range for a certain time, it is
deemed that the temperature is stable. This time is called stability
judgement time. Like PID constants, stability judgement time is ad-
justed with fuzzy self-tuning according to the characteristics of the
object to be controlled. Fuzzy self-tuning will not be activated if the
temperature is stable because the Temperature Controller deems
that temperature control is smooth.

Balanced Status
If the process value is within the stable range for 60 s when there is
no output, it is deemed that the the temperature is balanced.
Startup Conditions of DT
1. DT will start if the temperature that has been stable varies due
to external disturbance and the deflection of the temperature
exceeds the stable range, and then the temperature
becomes stable, provided that the number of maximum
temperature values is less than four.
2. DT will start if the set point is changed under the condition that
SRT does not start and the temperature becomes stable,
provided that the number of maximum temperature values is
less than four.
If there are four or more maximum temperature values, HT
will start.

Precautions
General Precautions
Operating Environment
Keep within the rated ambient operating temperature, ambient op-
erating humidity, and storage temperature ranges.
Use the Unit according to the vibration resistance, shock resist-
ance, and enclosure ratings.
Do not use the Unit in places with corrosive gas or excessive dust.
Do not use the Unit nearby machines generating high-frequency
noise.
Correct Use
Mounting
The dimensions of the Digital Controller conform to DIN 43700.
Recommended panel thickness is 1 to 8 mm.
Mount the Unit horizontally.
Connection
To reduce inductive noise influence, the lead wires connecting the
input type to the Digital Controller must be separated from the power
lines and load lines.
Use the specified compensating conductors for thermocouples.
Use lead wires having a small resistance for platinum resistance
thermometers.
Connection Example
Wire the terminals of the Unit using solderless terminals.
The tightening torque applied to the terminal screws of the Unit must
be approximately 0.78 N S m or 8 kgf S cm.
Use the following type of solderless terminals for M3.5 screws.
7.2 mm max.
7.2 mm max.
Operation
The alarm outputs of a model with an alarm function may not turn
ON properly when the model malfunctions. The use of alarm equip-
ment with the model is recommended.
The parameters and internal switch are set before shipping so that
the Unit will function normally. Change the settings of the parame-
ters and internal switch according to the application if necessary.
Several seconds are required until the relay is turned ON after pow-
er has been supplied to the Digital Controller. Therefore, take this
time delay into consideration when designing sequenced circuits
which incorporate a Digital Controller.
Do not use excessive force when drawing out the internal mecha-
nism from the housing. Protect the internal connector or electronic
parts of the Unit from shock. Protect against static discharge when
changing the settings of the internal switch. Changing the settings
on a grounded conductive mat is recommended.
When connecting the Control Output Unit to the Temperature Con-
troller or Digital Controller , make sure that the Control Output Unit is
a suitable type. The use of an improper type of Control Output Unit
may cause the system to malfunction.
The heater burnout alarm will not be available if the Linear Output
Unit is used.
