CAUTION!
Incorrect metering due to sensor failure
Possible consequence: Slight or minor injuries. Material damage.
– If a sensor fails then there may be an incorrect measured value at the input of the
measuring/control unit.
– This incorrect measured value can lead to uncontrolled metering.
– The operator should therefore ensure that no subsequent damage results from this.
CAUTION!
Incorrect metering due to premature ageing of the sensor
Possible consequence: Slight or minor injuries. Material damage.
Measure: Do not disconnect the sensor from the power supply during measuring breaks.
Exception: If there is a break between measurements lasting more than a week and the pro‐
portion of disinfectant in the sample water falls during this period to 0 ppm then electrically
disconnect the sensor.
– An extra run in period will be necessary following operation without disinfectant. Switch
on the feeder assembly with a time delay if necessary.
Run in period
The sensor requires a specific run in period to display a steady display value.
With initial commissioning:
When re-commissioning:
When replacing electrolyte or diaphragm:
* the exact run in period depends on the application.
