6.3
Calibration of the UV C 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.
NOTE
The CALIBRATION key is only released 1 minute after having activated the UV disinfection
system. Thus, the UV C sensor can be calibrated 1 minute after having activated the UV
disinfection system at the earliest.
Calibration

Press CALIBRATION
for 2 seconds;
the displayed UV C sensor signal starts to flash
왘
Press ENTER
for 2 seconds within 5 seconds;

After 2 seconds, the system returns to the standard display. The alarm threshold and the safety
threshold are now newly set. The operating hours counter as well as the counter of the lamp
activations are now reset to zero.
The calibration of the UV C sensor is now complete.

Maintenance
The maintenance of the UV disinfection system is limited to the cleaning of the lamp protection
tube as well as the replacement of the lamp at the end of the maximum permissible service life.
An operating journal should be used for documentation; a form is enclosed in the annex.
WARNING
•
Replace the UV lamp after expiry of the maximum permissible service life at the latest!
Otherwise, the operating safety of the UV disinfection system is no longer guaranteed.
•
The maximum permissible service life is described in the datasheet enclosed with the
UV disinfection system!
•
Disconnect from mains before commencing any maintenance work!
•
Depressurise the radiation chamber before commencing any maintenance work!
•
UV C radiation is harmful to eyes and skin.
Only commission the UV lamp when installed!
Properly install the UV disinfection system before commissioning the lamp!
