Commissioning and operation
49
– In the case of an engine slow down alarm, short-term lowering of engine
speed below 800 rpm so that higher engine speed can be reached
– In the case of a stop alarm, the alarm can only be deleted if the engine is at
a standstill
The following light-emitting diodes function continuously:
D
Power on: Diagnosis unit is receiving voltage
D
Ignition: Ignition is on
D
Serial data activity: Data interchange at the bridge.
If this fails, no more data is displayed on the bridge, neither
on the display (MMDS-L /-LC) nor on the round instruments.
The two light-emitting diodes below the “Horn off” key must
always be functioning.
The light-emitting diode below the “Test” key only reacts when
alarms are acknowledged.
If the following light-emitting diodes light up, there is a fault
D
Diagnostic unit failure: The diagnosis unit is defective
D
Sensor failure: A sensor is defective. The measurement point of the defective
sensor flashes with the same frequency as “Sensor failure”
D
Speed sensor failure: Defective engine speed input
D
Remote slow down: Remote reduction of speed.
Alarm at other engine. The defective engine reduces
the intact engine.
This prevents a curving manoeuvre in the case of an alarm.
Shutting down
After the engine has been running at a high load level, do not shut it down immediately
but allow it to idle about 5 minutes so that temperatures may equalize.
Set deck switch to “Neutral” and switch off the engine at the ignition key.
Remove key from starting lock.
Danger:
Ensure that the engine can not be started by unauthorized persons.
