9.4.7.2 Connection of amperometric sensors
9.4.7.3 Connecting the conductive conductivity sensor
Tab. 15: If you use a sensor without a fixed cable or wish to extend the fixed cable, you must use the pre-
assembled sensor cables:

Connect the sensor, as described in the sensor operating instruc‐
tions, to the corresponding terminals of the controller, see
Ä Chapter 9.4.5 'Terminal diagram' on page 42 .
NOTICE!
The sensor must be dry
Do not allow the conductivity sensor to come into
contact with liquid. Only allow the conductivity
sensor to come into contact with liquid once the
conductivity sensor has been connected, config‐
ured and calibrated. The sensor parameters (zero
point) of a moist or wet conductivity 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 recalibrated to the
sensor parameters.
Shielded sensor cable
All conductivity sensors connected to the controller require a
n
shielded sensor cable.
Connect the sensor in accordance with the terminal diagram.
n
Adjacent power lines
In the event of a fault, ensure that no lines are touching an
n
adjacent power circuit.
Solution: Strip off the outer sleeve of the cable as short as pos‐
n
sible.
Use cable ties to fix the wires.
n
All the sensor-dependent settings are reset to the
values when the connected sensor is changed.
