HOW TO DISMANTLE SYSTEM 5000

First, remember to demount the connectors with hazardous voltages. By lifting the
bottom lock, the module 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 program-
ming connector is accessible as shown in picture 3.

PROGRAMMABLE TRANSMITTER 5114
Input for RTD, TC, mV, linear resistance, mA, and V
3-port 3.75 kVAC galvanic isolation
Current and voltage output
Universal voltage supply
1- and 2-channel versions
Loop supply > 18 V in Ex zone 0

APPLICATION:

Electronic temperature measurement with resistance sensor or thermocouple
sensor. • Ex barrier for temperature sensors, potentiometers, and current /
voltage signals • Ex power supply for 2-wire transmitters in zone 0, 1, and 2.
• 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. • The transmitter is especially suitable for
emitting the output current signal, either as a standard current signal or as a
loop signal.

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 jumpers 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 tempera-
ture 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 Windows 95/98/-NT-based PC and PR electronics A/S' communica-
tions interface Loop Link 5905.

INPUT TYPES:

Temperature input - jumpers in position 1:
Thermocouple input (TC) for standard thermocouples type B, E, J, K, L, N, R, S,
T, U, W3, W5 according to the norms IEC 584, DIN 43710 and ASTM E988-90.
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
