7.2.2 Menu settings and description
Any menu can be retrieved by selecting NEXT on the operation display. One is directed to respective
menu settings by selecting ENTER. After leaving the menu setting, the display reverts back to the
standard operation display screen.
Generally, inputs or settings are displayed in addition to NEXT and ENTER.
If there is no input within 6 minutes in a menu mode, then the display automatically switches back to
the standard operation mode display.
Each menu setting must be set to the respective position the first time the controller is used. Any
adjustments are permanently stored in the internal memory, and can be overwritten at any time.
RESET Function / Factory settings:
The device can be reset to factory settings by the simultaneous pressing of both the NEXT and ENTER
buttons (for approx. 5 s)
1.
Time: 00:00:00 hrs
2.
Number of membranes: MEM = 1
3.
Start time T1: T1 = 03:00 hrs
4.
Start time T2: T2 = 15:00 hrs
5.
Pump cycles: A1/A2 = 55 / 0
6.
Blower time: Air ON / Air OFF = 5 / 5 (min/min)
7.
Suction overflow: SO=0 week
8.
Sludge pump: SLP/t=14 /30 (days/sec)
Menu 1: Number of membranes
(MEM = 1 to 6)
With this setting, the number of installed membranes is confirmed. This has reference to the
best setting for suction pump performance in the filtration process.
Note: MEM can always be modified even while flushing/backflushing is in progress.
Menu 2: Suction overflow
(Suction Overflow SO = 0 to 4)
This setting determines how many weeks shall pass before the pump will automatically
enforce a controlled overflow of the bioreactor tank.
With this function, through the AQUALOOP pre-filter, the sediment/light weight sludge at the
bottom of the tank is siphoned/drawn out via the suction overflow. As the water level rises,
the surface contaminants are sucked out through the overflow skimmers.
SO week = 0: Not operating.
SO week = 1 to 4: Suction overflow after first, second, third or every fourth week. (The
aeration Air ON/OFF further runs in normal rhythm.)
