9.2 Other failures
In addition to the monitoring function performed by the control unit (see chapter 9.1 “S40
control alarm messages”), the basic plant functions must be checked with visual inspections.
It is important to be able to recognise unusual water levels.
The plant is too full
overall; the water
level is so high that
the wastewater is
flowing out of
the emergency
overflow.
The clearwater cannot be
transported out of the
plant because the
receiving water or
seepage system will not
absorb it.
The plant is hydraulically
overloaded.
Switch on the clearwater lifter
and observe whether the
wastewater is carried away or
whether it flows back into the
plant.
Ask the operator if an unusual
amount of wastewater or
external water has entered
the plant.
The clearwater discharge
is not functioning,
because:
a. The hose is
connected incorrectly
b. The air lifter is not
receiving enough
compressed air
Check the function by
activating the clearwater lifter
in manual mode.
Check that the blue hose is
connected correctly.
Check:
Whether the compressor is
performing optimally during
aeration (check filters if
necessary).
Whether the blue hose is
damaged or bent.
Whether hose
connections/nozzles are
damaged, including in the
capsule.
Whether the air lifter is
blocked.
The valve is either defective
or not activated correctly
by the controller.
