Electric System LEXION Montana 570-520 TIC
41t-4 Lex-e-41t 03/05
Description of function:
Axle control system The system identifies the machine position using the inclination sensors
B126-1 / B126-2 which transmit their values to the MONTANA GEN II
module (A42) via an internal CAN bus. The solenoid coils (Y114, Y115,
Y116, Y117) are actuated by the MONTANA GEN II module (A42) so that
the machine is always in a vertical position by means of front axle
movements.
Front attachment control
system
The position of the front attachment is adapted by rotating the front
attachment frame (Y112, Y113) and by changing the cutting angle (Y110,
Y111). This front attachment control system works in addition to and
independently of the CLAAS AUTO-CONTOUR system (CAC).
The MONTANA GEN II module (A42) receives the necessary feedback
about the current position of the corresponding function from the
respective angle sensors (B91, B92, B93, B94, B95).
Montana axle hydraulics
master valve
The MONTANA GEN II module energizes the working hydraulics
master valve (Y77) with priority, according to the actuated MONTANA
functions. Actuation here is via the CAN bus. Only when the control
deviation becomes too small within a defined period of time (e.g. machine
raises too slowly), the MONTANA master valve (Y128) is additionally
energized – see circuit diagram 4t.
Calibration of
MONTANA system
All calibrations are carried out via the CEBIS terminal in connection with
the CLAAS Diagnosis System CDS.
Diagnosis of
MONTANA system
Reading out of data and display of sensor values is by means of the
CLAAS Diagnosis System CDS.
