The causes of errors are tabulated in the order of their probable
frequency. To find an error, go through the list from top to bot-
tom.
Attention! Only open the cover of the terminals or lamps when
the system is switched off. Do not measure the lamp’s burning
voltage under any circumstances as the high-frequency signal
could destroy the measuring device.
Warning! The lamp is ignited by means of a high voltage pulse
generated by the ballast. Do not measure this pulse under any
circumstances as it represents a serious hazard to human beings.
Table G-1: Troubleshooting
This is what you observe This is the cause This is what to do
Er 1 and UV lamp light up. Irradiance < limit value.

System is dirty inside.

Service life (730 days or
18,000 h) of UV lamp has been
exceeded.

Clean the system (rinse).

Replace the UV lamp
Recalibrate the system sensor.
Er 1 and UV lamp do not light up.

UV lamp is defective.

Ballast is defective.

Replace the UV lamp.

Replace the ballast.
Er 2 and LED ALARM flash Irradiance is now only 10% above
the limit value (Er 2 only displayed
in the error memory). After switching on the cold UV
lamp, Er 2 is most probably in the
error memory because the irradi-
ance only slowly increases.
When the LED ALARM flashes
continuously:

Clean the system (rinse).

Replace the UV lamp.

Recalibrate the system sensor.
Er 3 Temperature flushing (only when
the optional temperature flushing
system is installed). Is a normal operating response
after a longer time period without
water withdrawal.

Water temperature > 38 °C.

Set rinsing temperature lower.

Check the functionality of the
rinsing valve.
