knobs or potentiometers during normal operation.
RECEIPT AND UNPACKING
Unpack the device without damaging it. The packing should always follow the
device until this has been permanently mounted. Check at the receipt of the device
whether the type corresponds to the one ordered.
ENVIRONMENT
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as
well as rain and heavy moisture. If necessary, heating in excess of the stated limits
for ambient temperatures should be avoided by way of ventilation.
All devices fall under Installation Category II, Pollution Degree 1, and Insulation
Class II.
MOUNTING
Only technicians who are familiar with the technical terms, warnings, and
instructions in the manual and who are able to follow these should connect the
device.

4 5131V104-UK
Should there be any doubt as to the correct handling of the device, please contact
your local distributor or, alternatively,
PR electronics A/S
www.prelectronics.com
Mounting and connection of the device should comply with national legislation for
mounting of electric materials, i.e. wire cross section, protective fuse, and location.
Descriptions of input / output and supply connections are shown in the block
diagram and side label.
The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power
switch, it should be easily accessible and close to the device. The power
switch should be marked with a label telling it will switch off the voltage
to the device.
Production year can be taken from the first 2 digits of the serial number.
CALIBRATION AND ADJUSTMENT
During calibration and adjustment, the measuring and connection of external
voltages must be carried out according to the specifications of this manual. The
technician must use tools and instruments that are safe to use.
NORMAL OPERATION
Operators are only allowed to adjust and operate devices that are safely fixed in
panels, etc., thus avoiding the danger of personal injury and damage. This means
there is no electrical shock hazard, and the device is easily accessible.
CLEANING
When disconnected, the device may be cleaned with a cloth moistened with
distilled water.
LIABILITY
To the extent the instructions in this manual are not strictly observed, the customer
cannot advance a demand against PR electronics A/S that would otherwise exist
according to the concluded sales agreement.

HOW TO DEMONT SYSTEM 5000
First, remember to demount the connectors with hazardous voltages. By lifting the
bottom lock, the device is detached from the DIN rail as shown in picture 1.
Then, by lifting the upper lock and pulling the front plate simultaneously the PCB
is removed as shown in picture 2.
Switches and jumpers can now be adjusted. By opening the front, the programming
connector is accessible as shown in picture 3.

2-WIRE PROGRAMMABLE
TRANSMITTER 5131
• Input for RTD, TC, mV, linear resistance, mA, and V
• 3.75 kVAC galvanic isolation
• 4...20 mA loop output
• 1- and 2-channel versions
• ATEX Ex version
• DIN rail mounting
Application
Electronic temperature measurement with resistance sensor or thermocouple
sensor. • Ex barrier for temperature sensors, potentiometers and current /
voltage signals. • Conversion of current signals from supplied transmitters to
2-wire 4...20 mA signals. • Amplification of mV signals. • Conversion of linear
resistance variation. • Galvanic isolation of analogue signals. • Measurement of
floating signals. • Linearisation of non-linear Ohm, mV, mA, or voltage signals.
• Separation of circuits in PELV/SELV installations.
Technical characteristics
The unit is based on a microprocessor core with an efficient program operation.
The basic calibration data and present set-up are stored in an EEPROM thereby
avoiding the loss or change of data at power off. The 2-channel version has a full
galvanic isolation between the channels. By way of a jumper on the PCB the input
in the standard version can be programmed either for a temperature or a current /
voltage input. This means that one channel can work as for instance a temperature
transmitter and the other can work as an isolation amplifier. Measurement range,
signal parameters, and output span are configured to the present task by way of a
PC and PR electronics A/S’ communications interface Loop Link.
Input types
Temperature input - jumper in position 1:
Thermocouple input (TC) for standard thermocouples type B, E, J, K, L, N, R, S, T,
U, W3, W5, LR according to the norms IEC 584, DIN 43710, ASTM E988-90 and
GOST 3044-84.

5131V104-UK 7
The CJC can be selected in 3 different ways: internally in the terminal, externally
by way of a Pt100 / Ni100 sensor, or externally with a constant temperature. If
internal compensation is selected, a terminal with a built-in temperature sensor
must be ordered separately (PR type no. 5910 and 5913). Sensor error detection
is available.
RTD input for Pt100...Pt1000 according to the norm IEC 751 and Ni100...Ni1000
according to the norm DIN 43760. Automatic cable compensation at a 3- or
4-wire connection. At a 2-wire connection the cable resistance can be entered
or measured by the configuration program and sent to the device which then
compensates by the entered cable resistance. Sensor error detection is available.
Resistance input for resistance measurement with cable compensation as
described under the RTD input. Sensor error detection is available.
The mV input is programmable in the range -150...+150 mV.
Current / voltage input - jumper in position 2:
The current input is programmable in the range 0...100 mA, for instance 4...20 mA.
The voltage input is programmable in the range 0...250 VDC.
Output
Standard loop 4...20 mA current output. The output signal is proportional and linear
to the value of the input signal. Special set-ups can be selected in the configuration
program, for instance a customised linearisation, a reversed output, a limiter
according to the selected output span, and selection of an output value in case of
a sensor error. Maximum load on the current output is 1375 Ω.
Sensor error detection
The output can be set up at a RTD, thermocouple and linear resistance input to
go to max., to min., entered value, NAMUR NE43 Upscale or Downscale at sensor
error detection.
Configuration
The transmitter is configured to the present task by way of a and PR electronics
A/S’ communications interface Loop Link. The transmitter can be configured with
or without a connected supply voltage as the communications interface supplies
the necessary voltage to the set-up. The communications interface is galvanically
isolated to protect the PC port. Communication is 2-way to allow the retrieval of
the transmitter set-up into the PC and to allow the transmission of the PC set-up
to the transmitter. For users who do not wish to do the set-up themselves, the
5131 can be delivered configured according to customer specifications: input type,
measurement range, sensor error detection, and output signal.
