Description of function:
Starting The safety start switch circuit of this engine is identical with the one used
on the mechanically controlled engines.
The engine controller module (A15) is activated via relay K51 by the
ignition lock (S64). During the starting procedure, the engine controller
module (A15) receives the speed signal from the sensor provided on the
camshaft and starts the injection.
Engine monitoring All sensors relevant for operation and monitoring of the engine are
mounted on the engine wiring loom. Only the water level sensor is
connected to the CLAAS wiring loom.
The coolant level monitoring is fully electric. An optical and acoustic
warning is given when the diesel engine is not running (K23 is not
activated – see also diagram 3a).
A lack of coolant during operation makes the engine temperature rise.
This temperature in turn is read in and processed as a safety parameter
of the diesel engine.
The engine controller module (A15) transmits the signals for displaying
the coolant temperature and the engine speed to the CAB module (A10)
via the CAN bus J1939. The CAN module (A10) converts this signal to the
CLAAS CAN bus, thus allowing display on the terminal.
Engine diagnosis The number of engine errors occurred and the corresponding error codes
can be displayed in the terminal. Further diagnosis is carried out using the
DM diagnosis plug and the Daimler Chrysler diagnosis tool Minidiag.
Diesel engine speed
adjustment
The diesel engine speed depends on the position of switch S35. Three
positions are possible, i.e. idle speed, half throttle and full throttle.
When third gear is engaged, gearbox switch Z95 cuts the power supply to
the CAB module (A10) and the diesel engine speed is reduced – road
travel (see also diagram 44). The maximum speed which can be achieved
now is country-specific and can be configured using the Claas diagnosis
system CDS.
