4.2 Measurement unit connection

Attention: Switch off power supply before opening the housing cover. Do not install or connect the unit to power. If this is not followed

parts of the electronic circuit will be damaged.

• Sensors: Connect the sensor lead to the respective head transmitter terminals (Terminals 3 to 6) by following the wiring diagram

(see figure 4.1).

• Output signal and power supply: Open the PG cable gland on the head transmitter or field housing. Feed the cable through the

opening in the PG cable gland and then connect the cable cores to terminals 1 and 2 according to the wiring diagram (see figure

4.1).

• PC configuration (SETUP socket): Open the flap on the SETUP socket (Figure 4.1, Pos. A) and connect the SETUP connection

cable.

Note: The screws on the terminals must be screwed tightly. Head transmitter configuration during measurement operation is possible.

There is no need to disconnect leads.

POTENTIAL LEVELING

Please take note when installing the head transmitter remotely in a field housing. The screen on the (4 to 20) mA signal output must

have the same potential as the screen at the sensor connections. When using earthed thermocouples, screening of the output

(4 to 20) mA cable is recommended. In plants with strong electromagnetic fields, screening of all cables with a low ohm connection

to the transmitter housing is recommended.

5 OPERATION

5.1 Short form instructions (SETUP)

5.2 Communication

The head transmitter must be set up using a PC and configuration kit. The following points must be taken into account if trouble

free setting up is to be achieved:

• Configuration software installation

• Connect the head transmitter to the PC using the connection cable from the configuration kit.
