Operation and control (Compact Control)
The control of the UV system is used to monitor and control the
connected UV lamps, valves etc.
The control monitors the lamps in the UV disinfection unit during
operation, switches connected valves, and issues a message:
n
when the required safety threshold is transgressed.
n
when a thermal switch is required if a defined operating tem‐
perature is exceeded.
n
when a flow detector is required if a defined flow is trans‐
gressed.
During operation, the control displays the radiation intensity in
W/m
2
, the operating hours and the lamp activations alternately (60
seconds / 10 seconds / 10 seconds).
5.1 Operating modes
The control has 3 operating modes:
n

The control can be switched to
‘Automatic’ operating mode exter‐
nally.
Bridge in terminal 7/8
If the control is not controlled externally, then ter‐
minal 7/8 must be bridged.
Remote activation is provided by the contact of terminal 7/8.
5.2 Operating levels
The UV system is operated exclusively at operating level L5. L5 is
the sole operating level authorised for operation in compliance with
