3.7 Platform operation devices which are not part of the safety
system
On both connecting rod assemblies (right and left) connecting the tracked
chassis and the central frame, there are two Can Bus angle sensors.
The angle sensors are redundant (thus consisting of two separate sensors) and
monitor the X inclination axis of the respective connecting rod.
The values of the two sensors are constantly compared with the X values of the
sensors attached to the frame.
By measuring their difference, it is possible to determine the relative position of
the connecting rod with respect to the frame.
The position of the two connecting rods is used by the control unit to decide
which one should be moved during the lateral levelling operations (according to
the X axis).
Since neither the travel height nor the operating height depend on the position
of the connecting rods, they are not part of the safety system but only of the
system required for the operation of the machine.
