Description

Resistance/potiposition transducer

MINI MCR-SL-R-UI(-SP)

Data Sheet

INTERFACE

The slim MINI MCR-SL-R-UI... potiposition transducer has a

width of only 6.2 mm and converts potentiometer positions

as a percentage to an analog standard signal. If the potenti-

ometer range cannot be utilized to the full, an externally ac-

cessible slide switch is used to set the upper and lower poti-

position end values. The output signal between 0 and 100%

is based on this fixed end value.

The DIP switches are accessible on the side of the housing

and allow the following parameters to be configured:

–

Output signal,

–

Automatic potentiometer detection,

–

Open circuit detection slider and

–

Fault evaluation type.

Power (19.2 V DC to 30 V DC) can be supplied through con-

nection terminals on the modules or in conjunction with the

DIN rail connector.

WARNING: Correct usage in potentially explosive areas

The module is a category 3 item of electrical equipment. Follow the instructions provided here during instal-

lation and observe the safety instructions.

Make sure you always use the the latest documentation.

Safety notes

WARNING: Correct usage in potentially explosive areas

The module is a category 3 item of electrical equipment. Follow the instructions provided here during instal-

lation.

Install the module in housing with IP54 protection according to EN 60529. The specified limits for mechanical

strain or thermal loads for the module must not be exceeded.

Only modules suitable for operation in zone 2 potentially explosive areas may be connected.

Repairs must not be carried out by the user.

In potentially explosive areas, snap the module onto the DIN rail and connect the cables only when the power

is disconnected.

CAUTION

Installation, operation, and maintenance may only be carried out by qualified electricians. When installing and

operating the device, the applicable safety directives (including national directives), accident prevention re-

gulations, as well as general technical regulations, must be observed.

CAUTION: Electrostatic discharge

The module contains components that can be damaged or destroyed by electrostatic discharge. When hand-

ling the module, observe the necessary safety precautions against electrostatic discharge (ESD) according

to EN 61340-5-1 and EN 61340-5-2.

Power supply

Supply via the MINI Analog Module

Where the total current consumption of the aligned MINI Analog modules does not exceed 400 mA, the power can be sup-

plied directly at the connection terminal blocks of one MINI Analog module. A 400 mA fuse should be connected.

Supply via a Power Terminal Block

The MINI MCR-SL-PTB power terminal block (Order No. 2864134) or the MINI MCR-SL-PTB-SP power terminal block (Or-

der No. 2864147), which are the same shape, are used to supply the supply voltage to the DIN rail connector. A 2 A fuse

should be connected.

Supply via the System Power Supply Unit

The system power supply unit with 1.5 A output current connects the DIN rail connector to the supply voltage and can thus

be used to supply several modules from the mains.

– MINI-SYS-PS-100-240AC/24DC/1.5 (Order No. 2866983)

– Potentially explosive areas:

MINI-PS-100-240AC/24DC/1.5/EX (Order No. 2866653)

ATTENTION

Never connect the supply voltage directly to the DIN rail connector.

It is not permitted to draw power from the DIN rail connector or from individual MINI Analog modules.

Installation

The assignment of the connection terminal blocks is shown

in the block diagram. The module can be snapped onto all 35

mm DIN rails according to EN 60715.

When using T-BUS DIN rail connectors, first insert the DIN

rail connector in the DIN rail to bridge the power supply (see

assembly). Direction: Snap-on foot below and connector left.

WARNING

In potentially explosive areas, snap the modu-

le onto the DIN rail and connect the cables only

when the power is disconnected.

ATTENTION

Never connect the supply voltage directly to

the DIN rail connector.

It is not permitted to draw power from the DIN

rail connector or from individual MINI Analog

modules.

If the modules are not configured (all DIP switches set to

pos. 0), the module does not have a defined function until the

DIP switches have been set.

You can use the S1 DIP switch to prescribe the output signal

range, potentiometer/open circuit detection and fault evalua-

tion.

Activate automatic potentiometer detection to obtain opti-

mum measurement results.

You can use the S2 DIP switch to select the voltage and cur-

rent output.

CAUTION: Electrostatic discharge

The module contains components that can be

damaged or destroyed by electrostatic di-

scharge. When handling the module, observe

the necessary safety precautions against elec-

trostatic discharge (ESD) according to EN

61340-5-1 and EN 61340-5-2.

The "Teach In" function serves to adjust the potentiometer

range if it is not possible to exploit the entire range and yet

the output signal is to be exploited to the full. The press/slide

button provided under the transparent cover is used for con-

figuring the settings.

Setting to the lower Teach-In value

Set the potentiometer to the lowest Teach-In value and press

the button downwards for approx. 1 second (towards termi-

nal 1). If the value is saved successfully, the LED flashes

once.

Setting to the upper Teach-In value

Set the potentiometer to the highest Teach-In value and

press the button upwards for approx. 1 second (towards ter-

minal 5). If the value is saved successfully, the LED flashes

once.

Resetting to the lower potentiometer value

If the button is pressed downwards for more than 3 seconds

(towards terminal 1), the lower Teach-In value is reset to the

lower potentiometer value. After deleting the values success-

fully, the LED flashes twice.

If the button is pressed for more than 3 seconds, both Teach

In values are reset and the entire potentiometer range (0 %

to 100 %) is used.

Resetting to the upper potentiometer value

If the button is pressed upwards for more than 3 seconds (to-

wards terminal 5), the upper Teach-In value is reset to the

upper potentiometer value. After deleting the values suc-

cessfully, the LED flashes twice.

If the button is pressed for more than 3 seconds, both Teach

In values are reset and the entire potentiometer range (0 %

to 100 %) is used.
