Belt hand-over controller

The belt hand-over controller activates the drive of the belt hand-over. The position of the drive is indicated to the belt hand-over controller by a Hall sensor in the drive.

The end position of the extended belt hand-over is picked up by another Hall sensor. The end position is signalled to the belt hand-over controller.

Both signals are sent by the belt hand-over controller via the LIN bus to the footwell module (FRM).
