2 continue the program at the same point
where the cycle has been interrupted.
After a power failure > 30 minutes or after rebooting the control starts the cycle with the last
denitrification phase (exception with the XLA cycle; here the restart begins with the central
charging phase (i.e. with charging 5/10 with factory setting of 10 charges). Depending on the
water level in the buffer tank [SW3] with this one charging takes place.
Flushing pulses
To keep pumps free from sludge and to have a short operation during longer downtimes, the
charging, clear water, and sludge pumps are automatically switched on for the time of the
flushing pulse. This takes place in the middle of the settling phase or with each feeding
phase (independent of the position of the float switch).
Float switches
Open float switch (OFF)
= 0 in the status display
(float switch has dropped)
Closed float switch (ON)
= 1 in the status display
(Float switch has floated up)
ATTENTION! Switching can be detected through a clear “click”. The switch statuses
change relatively late (ca. +/- 50° related to the water level), so that a float switch that
has apparently already floated can still be open and a float switch that has apparently
already dropped down can still be closed.
Take note of status indicators!
