5.11.1 Alarms
The following alarm messages (pre-alarms and error messages)
are configured:
• *UV value?
• *Temp. Water?
• *Temp. Cabinet?
• *Flow?
• *Cleaning?
• *Lamp x?
• *UV Dose? (with activated dose function only)
• Pre-alarm UV
• Pre-alarm water temperature
The alarms are output via red or yellow (pre-alarm) LEDs on the
operating panel and / or voltage-free relay contacts. The error
messages are displayed as a text message and can also be view-
ed in the diagnosis menu. Safety deactivation of the lamps is also
configured (optional time delay). (For details on the criteria for trig-
gering safety deactivation, see 3.7.2 Safety functions, controller).
The contacts for the pre-alarms are NO (normally open), i. e. they
are open, when there is no pre-alarm. The contacts for the alarms
are NC (normally closed), i. e. they are closed, when there is no
alarm. The signal status can be viewed in the „Diagnosis” menu.
