BIF/CAB module (A10) The abbreviation BIF stands for the German "Bordinformator" (Fieldwork
computer), the abbreviation CAB for CAN bridge.
The essential machine data (serial no., operating hours, etc.) are stored in
this module = BIF.
At the same time, this module constitutes the interface between different
CAN bus systems (CLAAS - Caterpillar - Daimler/Chrysler) = CAB.
Data storage All yield data is saved in the yield meter module (A21) whereas all other
performance data is saved in the fieldwork computer / CAN bridge module
(A10). It is therefore recommended to transmit these data prior to
replacing a defective module, using the diagnosis system CDS.
MONTANA control unit
(axle and front attachment
control system)
The MONTANA control system includes the axle control system and a
front attachment control system complementing the CLAAS AUTO-
CONTOUR system (CAC).
The axle control system varies the height of the final drives of the rear
axle. For tilting the machine to one side, first the uphill side is lowered and
then the downhill side is raised.
The MONTANA front attachment control system allows varying the swing
angle (cross levelling) and the cutting angle by adjusting the front
attachment frame, in addition to the CAC functions.
The electronic control of the MONTANA functions is via a separate CAN
bus. The CAN data are converted in the MONTANA GEN II module (A42)
and made available to the CLAAS CAN bus system.
A
ccording to the axle position, the value of the feed rake conveyor position
sensor (B35) is offset in the AUTOCONTOUR module (CAC). This allows
working in hilly ground with the CAC function "Pre-set cutting height
control" and area counting.
