Note the electrical connection values on the nameplate of the
measuring and control station. The cable ends of the connecting
lines of the sensors are labelled according to the measured vari‐
able.
The cable ends of the connecting lines of the sensors are labelled
according to the measured variable. The cable ends are labelled
by a cable marker defined as follows for the respective measured
variables:

CAUTION!
Defective control by incorrect measured values
Cause: Electrical faults are coupled into the control
circuit via the sample medium.
Consequence: Defective control by incorrect meas‐
ured values. The measuring fault can lead to an
uncontrolled control circuit.
Measure: Do not fit any sources of EMC interfer‐
ence into the water circulation system and close to
the system.
Perform regular comparative measurements with a
galvanically isolated measuring device.
Provide for potential separation of the power
supply from the measuring device to the power cir‐
cuit of the voltage to be measured or a potential
separation in the measuring signal path.
Connect the system to its own power supply, if
needed.
Fit a power repeater, if needed.
Please also observe the operating instructions

for the controllers and fittings and any other
units, such as sensors, sample water pumps ...
