7.3.6.3 Connecting the conductive conductivity sensor
NOTICE!
The sensor must be dry
Do not allow the conductivity sensor to come into contact with liquid. Only allow the conduc‐
tivity sensor to come into contact with liquid once the conductivity sensor has been con‐
nected, configured and calibrated. The sensor parameters (zero point) of a moist or wet con‐
ductivity sensor can no longer be properly calibrated.
If the conductivity sensor has come into contact with liquid prior to calibration, there is an
option to dry the conductivity sensor. A dry conductivity sensor can be successfully recali‐
brated to the sensor parameters.
Shielded sensor cable
All conductivity sensors connected to the controller require a shielded sensor cable.
Connect the sensor in accordance with the wiring diagram.
Tab. 8: If you use a sensor without fixed cable or wish to extend the fixed cable, use the pre-assem‐
bled sensor cables:
Accessories Part number

Tab. 9: If you wish to extend the fixed cable with a CTF or CCT sensor, then use the pre-assembled
sensor cable:
