Cause
Sensor connecting cable incorrectly
attached.
UV sensor and/or lamp protection
tube is/are dirty.
UV lamp too old.
The spectral attenuation coefficient
SSK-254 of the water is too high.
Remote ON/OFF switch not con‐
nected or remote ON/OFF terminal
not bridged.
Cause
Indicates a UV lamp malfunction and the
number of malfunctioning UV lamps.
Indicates when the temperature of a con‐
nected thermal switch has been
exceeded.
Indicates that the adjusted minimum radi‐
ation intensity / warning threshold has not
been reached (e.g. due to water quality,
deposit formation, operating life of the UV
lamp).
WARNING!
Live parts!
Possible consequence: Fatal or very serious inju‐
ries.
– Measure: Disconnect the device from the

– Disconnect damaged and defective devices or
devices that have been tampered with from the
mains power supply.
– Only permit an authorised electrical technician
to undertake troubleshooting on the open con‐
trol cabinet and replace components.
Solution
Check connections and change if
necessary.
Perform cleaning.
Replace UV lamp.
Check the spectral attenuation coeffi‐
cient SSK-254 of the water and repro‐
gram S1 and S2 if necessary.
Ensure that the maximum permissible
flow is not exceeded in accordance
with the characteristic curve.
Connect and activate remote
ON/OFF switch or insert bridge in
remote ON/OFF terminal
Solution
Check contacts. Replace the UV
lamp.
