Calibration of UV sensor
WARNING
•
Only a correctly calibrated UV C sensor guarantees sufficient disinfection.
•
When calibrating the UV C sensor, the water to be disinfected must flow through the
radiation chamber.
IMPORTANT
When calibrating the UV C sensor, a new UV lamp must be used and the lamp protection
tube as well as the sensor window must be cleaned.
NOTE
See also Chap. 6.2 “Switching on of the disinfection system“.
The UV C sensor is to be calibrated during commissioning as well as at each lamp replacement.
During calibration, the alarm threshold and the safety threshold are newly set. The operating
hours counter as well as the counter of the lamp activations are reset to zero.
Before calibration, the UV C sensor signal must be stable. A changing sensor signal shows that
the UV lamp has not reached its final operating temperature.
