6.3.2 Steering controller LES / 3A1
6.3.2.1 Description
The LES (Linde Electrical Steering) steering controller is composed of a control card with two
microprocessors, a main “CP” and a safety “CS”, and a power stage with 4 Mosfet transistors. The
transistors are controlled by an electronic circuit called DRIVER (optocoupled for galvanic insulation)
located in the power stage.
If a fault appears, it is detected instantly and the control system is put in safety and controls the truck stop.
The control module is equipped with a connector 3X1 of 29 terminals.
