Display Device Mmds-L - Man D 2840 LE 403 Operating Instructions Manual

2. Display device MMDS-L

The engine monitoring alarms the officer
guiding the ship when important engine
operating values are outside the permitted
tolerance range.
D Acoustically by means of an integrated
buzzer or horn connected at the ship-
yard
D Visually in that the relevant warning
lamp flashes
The engine operating parameters shown
on the display device are monitored.
If gearbox parameters are to be moni-
tored, this depends whether the corre-
sponding sensors have been fitted in the
gearbox.
The device distinguishes between the following types of alarm, error messages:
D Preliminary alarm: the corresponding light-emitting diode flashes
D Main alarm:
D Sensor fault:
The alarm "Sensor fault" means that the corresponding sensor is classified by the moni-
toring system as defective, as it is returning an unrealistic value.
The engine speed is not reduced.
In the event of a fault in the electronic system, the warning lamp lights up continuously.
There is then a defect in the electronic fuel injection (EDC).
So as not to endanger the engine, the engine power is automatically reduced in the case
of selected main alarms.
Note for engines with electronically controlled diesel injection (EDC):
After the ignition has been switched on, the lamp "Electronic fault" lights up briefly
(lamp test). If there is a fault in the electronically controlled diesel injection (EDC),
the lamp "Electronic fault" lights up permanently.
