Storage time exceeded
Note: Flashing LCD and audible signal
ON/OFF (1 sec. / 1sec.)
-
The water in the bioreactor has
not been filtered for at least 21
days (no filtration process has
been started within this time)
-
Check the greywater inlet flow
-
Repeat the start –up phase of the
bioreactor (s. section 9.2)
Power failure
Note: Flashing LCD and audible signal
ON/OFF (1 sec. / 1sec.)
-
power failure for more than 2
hours
(Biological treatment could be
affected when the failure
duration is more than 1 day!)
-
If power failure is less than 1 day
please confirm with NEXT
-
If a power failure occurred for more
than 1 day please repeat the start –
up phase of the bioreactor (s.
section 9.2)
Aeration failure
Note: Flashing LCD and audible signal
ON/OFF (1 sec. / 1sec.)
-
Working pressure of the blower
is too low
(Biological treatment could be
affected when the failure
duration is more than 1 day!)
-
Water level in the bioreactor
too low < 30cm
-
Check the blower, replace if
necessary
-
If a power failure occurred for more
than 1 day repeat the start –up
phase of the bioreactor (s. section
9.2)
Optional if the pressure
sensor mounted:
Failure backwash pump
Note: Flashing LCD and audible signal
ON/OFF (1 sec. / 1sec.)
-
For 4 pump cycles, backwash
pressure > 0.1 bar was detected
(normal 0.3-0.5 bar).
-
Check the backwash pump in test
menu
-
If a pump failure occurred, clean
the pump in case of blockage or
replace the pump.
Informative: Maximum level
of the bioreactor
-
Floating switch detected the
maximum level in the
bioreactor (only if the floating
