Operation monitoring by EMR3
The EMR3 system monitors the engine condition
and itself.
The statuses are displayed by the error lamp.
z
Lamp test:
–
The error lamp lights up for approx. 2 s after
switching on the ignition (ignition lock stage
1)
z
Steady light:
–
There is a system error or an engine variable
(temperature, pressure etc.) is in the warning
range.
The EMR3 can reduced the engine perform-
ance depending on the error 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 auto-
matically depending on the application.
–
The control unit can preset a forced engine
operation with low idling speed to cool down
the engine before switching off, automatic
switch-off if necessary.
–
There may be a start lock after engine stop.
–
The start lock is released by switching off the
system with the ignition key for about 30 sec-
onds.
–
Additional control lamps, e.g. for lubricating
oil pressure or lubricating oil temperature,
are switched on if necessary.
–
The power reduction can be bypassed, the
automatic switch-off delayed or a start lock
bypassed with the override key on the instru-
ment panel to avoid critical situations. This
brief deactivation of the engine protection
functions is logged in the control unit.
Display instrument
Possible displays:
z
Colour scale
–
Display of the operating state by coloured ar-
ears (green = OK/red = take suitable action).
z
Measured value scale
–
Actual value can be read off directly. The
nominal value should be taken from the
Technical Data (
