Deni aer. ON/OFF: Aeration times/pauses during the
denitrification phase.
Aer. phase: Duration of the complete charging phase. ON/Off norm: Aeration times/pauses during
the normal phase.
Aer. ON/OFF econ: Aeration times/pauses during the economy phase.
sediment.: Duration of the settling phase.
CW evacuation: If the removal of the clarified water at the end of the settling phase takes longer than
the run time specified a flooding warning takes place.
followup: As the AQUAswitch

has a very small switching hysteresis, the
clarified water pump still continues to run on for the set time after 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
Selection of the volume of the alarm sound.
