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.
