DANGER
Voltage > 42 V
Direct contact with live parts may cause serious
injury or death.
The fixed connection to the operating mains must
only be done by trained specialists (electrician).
The 4 LEDs in the control box door indicate the basic
functions. The oil sepparator system can be started and
the operating modes selected via a main switch and a
switch "Hand"-"0"-"Auto". There are terminals for two level
switches in the bilge in order to switch automatic mode of
the system on or off depending on the level. By factory
default the terminals of the floating switches are bridged.
See chapter

7.8,Fig. 10 Control box
Decide whether to operate in "Manual mode" or
"Automatic mode".
Note
In "manual mode", the oil separator operates
independent of the level switch signals in the bilge.
The oily water separator does not switch off
automatically according to the level. Therefore you
should only select this mode if permanent monitoring
is ensured.
Switch on the main switch "POWER".
1)
The control light "RED-OILDISCHARGE" lights up in red
(oil to the collector tank), because the sensor electrode
indicates air and oil (both non-conductive media). The
pneumatic piston valves at the flushing water inlet
(pos. 15) and oil outlet (pos. 4) are open (voltage is
applied to both solenoid valves) and the system is
automatically filled with flushing water, at the same time it
is vented via the oil outlet. In this process, the pump
remains switched off.
As soon as the water level reaches the sensor
2)
electrode
(pos. 9) (conductive medium detected), the control light
switches over to “ORANGE-FLUSHING” (backflash). The
pneumatic piston valve (pos. 5) opens (voltage applied at
solenoid valve) and with a time delay the oil outlet valve
(pos. 4) closes (no voltage applied to solenoid valve).
As soon as the system is filled,
3)
the piston valves (pos. 5 and 15) close (no voltage applied
to either solenoid valve). The control light "GREEN
WATERDISCHARGE" lights up in green at the automatic
control box (water outboards). Now the pump starts up
and draws from the bilge. The system is now ready for
operation.
The heater can now be switched on with the switch
4)
"Heater".
