Description
The 6.2 mm wide MINI MCR-SL-R-UI... potiposition transducer converts potentiometer positions as a percentage of an
standard analog signal. If the potentiometer range cannot be
utilized to the full, an externally accessible slide switch is used
to set the upper and lower potiposition end values. The output
signal between 0 and 100% is based on this fixed end value.
Features
–
–
–
–
Configurable potipostion transducer
Output signal range can be configured using a DIP switch
Approval for Ex-zone 2 (nA)
Screw or spring-cage connection can be provided
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 loop as well as
– error indication type.
Power (19.2 V DC to 30 V DC) can be supplied through connection terminal blocks on the modules or in conjunction with
the DIN rail connector.
Attention: Correct usage in potentially explosive areas
The module is a category 3 item of electrical equipment. It is absolutely vital to follow the instructions provided
here during installation and observe the information in the "Safety regulations and installation notes".
Make sure you always use the latest documentation.
It can be downloaded from the product at www.phoenixcontact.net/catalog.

Installation in the Ex area (zone 2)
Observe the specified conditions for use in potentially explosive areas.
The device must be installed in a housing (control or distributor box) which meets the requirements of EN 6007915 and provides at least IP54 (EN 60529) degree of protection.
During installation and when connecting the supply and
signal circuits, observe the requirements of EN 6007914. Devices may only be connected to circuits in zone 2 if
they are suitable for operation in Ex zone 2 and for the
prevailing conditions at the place of use.
In potentially explosive areas, terminals may only be
snapped onto or off the DIN rail connector and wires may
only be connected or disconnected when the power is
switched off.
The device must be stopped and immediately removed
from the Ex area if it is damaged, has been subjected to
an impermissible load, has been stored incorrectly, or if it
malfunctions.

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
(Order No. 2864147), which are the same shape, are used to
feed the supply voltage to the DIN rail connector.
A 2 A fuse should be connected upstream.
Supply via a 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
therefore be used to supply several modules from the mains.

Use a screwdriver to tighten the screw in the opening
above the connection terminal block.
Spring-cage connection:
Mount the module on a 35 mm DIN rail according to EN
60715.
When using the DIN rail connector, first place it into the
DIN rail (see A – C). It is used to bridge the power supply.
It is also absolutely vital that you snap the module and the
DIN rail connector into position in the correct direction:
the snap-on foot should be at the bottom and the connector on the left.

Configuration
If the modules are not configured (all DIP switches set to position 0), the module does not have a defined function until the
DIP switches have been set.
The output signal range, potentiometer/open circuit detection
and fault evaluation is specified by the SP1 DIP switch.
Activate automatic potentiometer detection to obtain optimum
measurement results.
You can use the S2 DIP switch to select the voltage and current output.

Resetting to the upper potentiometer value
If the button is pressed upwards for more than 3 seconds (direction of terminal 5), the upper Teach-In value is reset to the
