6. The small wastewater treatment system's control unit
29 / 54
After the 5-second delay, there is an intermittent beep with a red flashing signal. Five
flashing signals and one beep repeat at intervals of 5 seconds for around 12 hours (if the
emergency power supply is fully charged).
The device cannot be switched off when in this state.
When the mains voltage is restored, the device is returned to the monitoring status and the con-
trol unit continues from where it left off without any keys having to be pressed. The fault mes-
sage disappears automatically. If the emergency power supply is flat, the device restarts with a
cycle pause.
Power cut
Please note:
If the system is disconnected from the mains for more than
24 hours, the system will be unable to clean the wastewater properly if at all.
Never switch off system
(the only exceptions are if maintaining system parts
and in the case of system faults restricting function)
