Sample water faults and alarm relays
If the sample water falls below the minimum flow
volumes (sample water fault), the controller
switches to fault mode and control of all measuring
channels stops.
The alarm relay is not factory-activated.

WARNING!
Sensor run in periods
This can result in hazardous incorrect metering.
Consider the run in period of the sensor when
commissioning:
– There must be sufficient feed chemical in the
sample water for your application (e.g. 0.5 ppm
chlorine).
– Correct measuring and metering is only pos‐
sible if the sensor is working perfectly.
– It is imperative that you adhere to the run in
periods of the sensor.
– Calculate the run in period when planning com‐
missioning.
– It may take a whole working day to run-in the
sensor.
– Refer to the sensor's operating instructions.
After mechanical and electrical installation, the controller must be
integrated into the measuring point.
