General Function
The system is powered directly from the vehicle battery (24V system).
Both motors are switched by a full bridge driver in the electronic box. The CDL motor has an
internal switch for signalling the mechanical position to the electronic controller. The OS motor has
an integrated strong spring for pulling the motor back into the “zero position”, so the OS motor
needs no switch inside.
The system can be used in both 12V and 24V systems. The CDL and OS motors are 12V motors.
Voltage and current of the motors are fully controlled by the electronic –> results are a constant
force in the full temperature range and a protection against overload and overheat.
The rotor switch monitors the information of a fully closed cabin door.
Power consumption in idle mode: < 8 mA
Power consumption with CDL motor working: < 5 A
Power consumption with OS motor working: < 9 A
