5.2 Measurement unit connection
Attention:
Switch off power supply before opening the housing cover. Do not install or connect the unit to mains power. If this is not followed parts of the electronic circuit will be damaged.
Sensors:
Connect the sensor cables to the respective head transmitter terminals (Terminals 3 to 6) by following the wiring diagram (see fig. 5.1).
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 fig. 5.1).
PC configuration (SETUP socket):
Open the flap on the SETUP socket (Fig. 5.1, Pos. A) and connect the SETUP connection cable.
Hint:
The screws on the terminals must be screwed up tightly. Head transmitter configuration during measurement operation is possible. There is no need to disconnect cables!
Potential leveling Hint:
Please take note of the following when installing the head transmitter remotely in a field housing. The screen on the output (output signal 4...20 mA) must have the same potential as the screen at the sensor connections! For an effective screening the cable screen must be widely connected to the field housing. This can be achieved by connecting the cable screen to the special EMC-PG13.5 cable gland.
Open the field housing PG cable gland and connnect the screen of the output and sensor connection according to Fig. 5.2.
