monitor OMD. No voltage is applied to the solenoid valve
of the 3-way valve (pos. 23). The 3-way valve (pos. 23)
guides the water back to the bilge or the bilge water tank.
The display of the oil separator control system still
indicates
and the oil separator keeps operating.
Additionally an alarm message to the engine control room
is activated. On the monitor, two red LEDs signal that both
limit values are exceeded and thus an alarm.
