reaching the actual float switch tripping point. Thus an inadvertent
“false” level signal caused by water movements is prevented.
Sl back
: Time for the excess sludge removal. This takes place once
during a cycle, immediately following an aeration.
Flush pulse
: In order to free the clarified water pump of activated
sludge, which has collected in the casing during the aeration phase,
the pump is operated during the settling phase for the time set (with the
BASIC the number of the charging batches). Through the short-term
build-up of a head of water and the subsequent subsidence, the sludge
is driven out of the casing.
run-in phase
: During the listed number of days no excess sludge
removal takes place.
Current limits
Minimum/maximum current consumption of the
individual units below/above which an alarm
signal takes place.
Alarm pause
If errors occur within the selected time interval
(max. 12 hours), then the acoustic alarm is
emitted only after run-out of this time.
Sludge evacuation
With activation the aeration times are reduced by
20% for a period of six weeks (no further reduction
in winter operation).
Following successful activation this function is
blocked for six months.
Signal sound
