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.
Refer also to the operating instructions for purchased parts
when troubleshooting.
A system fault/malfunction (collective alarm) is acoustically reported with a
warning tone and visually by the red warning light on the control cabinet.
The controller also displays a fault message. The warning tone can be
switched off by pressing
[Reset F4]
.
The activation of the downstream feed pump (polymer solution) remains
unaffected by the collective alarm.
The fault message must be acknowledged with the Reset key once the
cause of the fault has been eliminated so that the system can restart ope‐
ration following the fault.
Should a problem occur, which is not included in this list or should a listed
fault not be remedied by the suggested troubleshooting measures, please

For every fault analysis it should first be considered that a capacitive prox‐
imity sensor or a concentrate flow sensor may possibly be incorrectly sig‐
nalling a fault (because its sensitivity has been set too high or it is trig‐
gering/responding to suddenly changed ambient conditions).
