Operation monitoring by EMR3
z The EMR3 system operates the engine con-
dition and itself.
z The states are indicated by the fault lamp.
z Lamp test:
– The fault lamp lights for about 2 s after ig-
nition (ignition lock stage 1).
z Steady light:
– There is an error in the system or a vari-
able of the engine (temperature, pressu-
re, etc.) is in the warning range.
Depending on the fault, the engine perfor-
mance can be reduced by the EMR3 to
protect the engine.
z Fast flashing:
–
Attention, the engine is in danger and
must be switched off.
– The control unit switches the engine
off automatically depending on the ap-
plication.
– To cool down the engine before switching
off, the control unit can command forced
engine operation at low idling speed or
automatic switch off.
– There may be a start lock after stopping
the engine.
– Additional control lamps, e.g. for oil pres-
sure or oil temperature may be switched
on if necessary.
– With the override button, the power re-
duction can be bypassed, the automatic
shutdown delayed or a start prevention
bypassed to avoid critical situations. This
overriding of the engine protection func-
tion is logged in the control unit.
– The start lock is released by switching off
the system with the ignition key for about
30 s.
