Operation of the engine monitoring system BE1
The engine monitoring system BE1 warns
the ship operator if important engine oper-
ating values are outside the permissible
tolerance range.
The display unit of the engine monitoring
system (see picture) is installed in the
main navigating stand and, as an option,
in the secondary navigating stand (fly-
bridge) too. The alarm is raised:
D acoustically by means of a horn
D visually by the flashing of the respective
red check lamp (exception: in the event
of a fault in the electronic system the
respective check lamp is permanently
illuminated)
To protect the engine, the speed will be reduced if alarm warnings like engine oil pres-
sure, engine coolant temperature, charge-air temperature and coolant level) is raised.
The check lamp "reduced speed" is then illuminated permanently.

After the ignition has been switched on, the lamp "Fault in the electronic system"
will come on momentarily (lamp check). If there is a fault in the electronically con-
trolled diesel injection system (EDC), the lamp "Fault in the electronic system" will
be illuminated permanently.
