Each time mains power is switched on, the stirrer starts up without
regard to the system statuses measured.
Preparation mode can start every time mains power is switched on.
If it is necessary to work on the system, disconnect the system
from the mains/power supply and secure it to prevent it from being
switched back on.
Each time the mains power is switched on, the stirrer starts up

If there is a loss of mains power during preparation mode, even if
only for a short period, preparation mode is not continued once
mains power is reconnected.
Following a mains power failure, or in the event of a longer loss of
mains power, which results in the control being restarted, the con‐
troller will unrestrictedly continue with the operation of the system
based on the statuses measured.
