11.2 Behaviour When Switching on Mains Power and in the Event of Mains
Power Failure
WARNING!
Automatic start-up
Each time mains power is switched on, the stirrers start up
without regard to the system status measured
Each time mains power is switched on, preparation mode
can commence.
Therefore keep all covers or inspection openings closed.
If it is necessary to work on the system, disconnect the
system from the mains and secure it to prevent switching
back on.
Each time mains power is switched on, the stirrers start up without regard
to the system status measured
By contrast, the system only starts in preparation mode if the Min. Switch
point has been reached in reservoir 3. If there is a loss of mains power
during preparation mode, even if only for a short period, once mains power
is reconnected, preparation mode is not continued.
Following a mains power failure, or in the event of a longer loss of mains
power, which results in the controller being restarted, the controller will
unrestrictedly continue with the operation of the system based on the sta‐
tuses measured If the level of the storage tank is within the normal range,
no preparation operation will be started even if a preparation process was
running prior to the interruption
