Diesel engine electric starting motor

Montana machine is only in a cable branch at connector P to P1. The signal of ground speed control lever in neutral position (Z57) is required on Montana machines for releasing the gear shifting.

As a safety start switch, relay K53 is supplied with earth only when

switches (Z57a/Z57b) on the ground speed control lever are in neutral position and the threshing mechanism is disengaged via relay K13. The ignition lock (S64) then actuates the diesel engine starting motor (M21) via relay K53 with +50a.

Montana

Montana machine is only in a cable branch at connector Y to Y1. The gearbox switch on connector Y is dropped for Montana machines. The Montana functions are supplied with power via the unactuated relay K56. During the starting process, relay K56 is actuated and thus interrupts the power supply.

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.

mounted on the engine wiring loom. Only the water level sensor is connected to the CLAAS wiring loom. The engine controller module (A15) transmits the signals for displaying the engine speed and the coolant temperature 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.

codes can be displayed in the terminal (see also the error code list in the Electric System documentation

297550.x - Diagram 2e). Further diagnosis is carried out via the diagnosis plug in the central terminal compartment, using the Caterpillar diagnosis tool CAT-ET. The display of error codes can also be activated by the diagnosis LED (D1) after actuating the rocker switch (U22).

The diesel engine speed depends on the position of switch S35 and of the

2nd gear actual value switch (Z83) – see also circuit diagram 42s. If full throttle speed is selected and the 2nd gear engaged (signal input A36 / pin 4), the connection between Z41a and Z41b inside the Montana gearshift control module (A36) is cut (pins 10 and 11) – see also circuit diagram 42s. The full throttle speed is reduced to road travel speed, depending on the contry version. The maximum speed which can be achieved now can be configured using the Claas diagnosis system CDS.

Description of function:

Montana machine: On Montana machines, actuation of the working hydraulics master valve

Activation of road travel During road travel, the road travel switch (S52) must be locked in order to

cut the power supply for all unnecessary electrical and hydraulic functions.

In order to be able to build up the necessary working pressure for many

hydraulic controls, the neutral hydraulic circulation must be blocked (see also the "Hydraulic system" section). In this case, the solenoid coil (Y77) is actuated in parallel with the function directly via the diode PCB (DO) and the gearshift control module (A36). A LED (D5) provided on the diode PCB indicates the activation of the circuit.

For the Montana functions as well, the circulation of the independent axle

control system hydraulics must be blocked (see also "Hydraulic System" document). According to the actuated functions, the Montana control unit (A35) actuates the Montana master valve (Y128) and/or the working hydraulics master valve (Y77) via the gearshift control module (A36).

The sensor/switch (B90) controls the brake system accumulator pressure

and, if necessary, actuates the working hydraulics master valve (Y77) via the gearshift control module (A36) in order to recharge the brake circuit accumulator.

If the diesel engine speed drops below 2300 rpm while braking, the RIO

module (A50) actuates the working hydraulics master valve (Y77) via A50/pin R5 and the axle hydraulics master valve (Y128) via A50/pin R3. This hydraulic load on the diesel engine increases the braking effect. In addition, a brake restrictor is activated in the hydrostatic ground drive – circuit diagram 42s.
