9. Malfunctions and remedial measure faults
Faults
Battery voltage too high
Relay error
The display of the control
does not show anything or shows
the message "Mains failure"
The display shows the
message "Extraction"
Other possible faults
The water level in the preliminary
sedimentation is exceptionally
high, while the aeration exhibits a
normal water level
The water level in the preliminary
sedimentation and in the aeration
is exceptionally high
Causes
- Battery not available
- Battery contact error
- Relay contact in control unit is
stuck together
- The plant is currentless
- The display is defective
- Maximum extraction time too
short
- Uncontrolled inflow to the plant
(e.g. rain water, plant leaks)
- Water cannot drain off (e.g.
backup, compressed air syphon
hose not in drain)
- Floating switch too low (setting
see floating switch)
- Excessive impact load on plant
- Compressed air syphon for the
feeding is clogged
- Plant undersized
- Mains failure
- Exceedingly high external water
inflow. In case of heavy rainfalls
due to surface water or on soa-
ked soils due to a leaky tank.
- Compressor does not work
- Compressed air syphon for clear
water extraction is clogged
- Pressure hose leaky or no longer
connected.
Elimination
- Insert a battery
- Check battery polarity and seat
- Replace the control unit
- Check pre-fuse and / or earth
leakage circuit breaker
- Call after-sales service, adapt
maximum extraction time
- Ensure that there is no inflow of
external water into the plant
- Provide free drainage.
- Replace the floating switch
- Control the impact load
- If it is not possible to restore the
function even during longer ma-
nual operation, remove the
compressed air syphon and
rinse clean
- Adapt the inflow quantities or
expand the plant
- Connect the plant to the grid
- External water may not penetra-
te into sewage treatment plants
for a longer period of time. If ne-
cessary seal concrete tank or
eliminate other causes.
- Check function in manual mode.
If it is not possible to start up
the compressor, call the after-
sales service.
- If it is not possible to restore the
function even during longer ma-
nual operation, remove the
compressed air syphon and
rinse clean.
- Check connections and pressu-
re hose and if necessary restore
