9. Self-help in case of failure
Symptom Cause
Remedy
No display
-
Jumper (s. section 6.1) not
inserted
-
Plug in jumper
-
No 24 V voltage supply and
discharged battery
-
Display cable is loose or
defective
-
Check AC switching power
supply, recharge battery via
internal charging switch. *
-
Check display cable or change
display
Battery operating mode
display
-
Power failure
-
24 V Switching power supply is
not connected
-
24 V Switching power supply is
defective
-
Wait for power to come back on
-
Connect AC switching power
supply
-
Change AC switching power
supply
Display after power failure
-
Display (for 30 seconds) after
power failure of 24 V voltage
supply
-
Check the number of failures in
status mode in a period of 24 h,
for instance. If the number
increases and the reason is not a
general power failure, then the
power supply is to be checked.
Display after power failure
-
Display with power failure
during pump cycle
-
Check pumps via test menu. If
there is a power failure even in
test mode, then check for defect
in respective pump or power
supply.
Less clear water running

-
Leakage clogs the membrane
fibres
-
Check backflushing pump in
test mode (see. start-up
process) and change if
necessary
-
Perform leakage test (see.
section 8) and remove source
of leak if necessary
Display failure
-
Display crashed - for instance,
by voltage surge in power
supply (lightning) or
electrostatic effect
Note: The program runs
normally in future.
-
Restore the display function by
RESET (adjusted parameters are
lost) or disconnect the cable
bridge (s. section 6.1) on
control board.
* Note:
If the battery voltage does not reach more than 8.5 Volt (see. Status display) after a charging period of
approx. 14 h, then the battery needs to be replaced.
