E.g.:
UV treatment is based on operating data for the end of the lifetime of the radiator, which is
indicated by a 50 % radiation output. In order to achieve a constant radiation output greater
than 50 %, the reference value must be set at 60 %, the safety threshold at –10 [%] and the
warning threshold at –5 [%]. Regardless of the lifetime of the radiator, the radiation output is
now automatically readjusted so as to constantly obtain a probe signal equal to 60 % of the ori-
ginal value. If the signal falls short of this value by 5 per cent, a warning message will be issued.
With a 10 per cent shortfall an alarm message is issued and the system shuts down, as now the
minimum radiation output has fallen to 50 %, which was the level defined when designing the
system.
6.3.3.2 Setting the radiation output in operating mode "external control"
Before commissioning the operating mode "external control ", a definitive reference value zzz
needs to be calculated for the system:
zzz = reference value x F/F
