DescriptionA device allows the headlamp beam to be adjusted, directly from the driver's seat, in accordance with the load. The headlamps are thus always aligned quickly and correctly. The adjustment device consists of a motor mounted on each of the two headlamps which tilts them as appropriate, lowering the light beam if the car is heavily laden, and raising it if the load decreases. A specific knob in the dashboard selects the four positions indicated:position 0 - up to three persons in the front seats;position 1 - six persons;position 2 - six persons with luggage in the boot;position 3 - driver and maximum load, all stowed in the boot.The device is only enabled when the dipped headlamps are switched on.The headlamp adjustment circuit is protected by the same fuses as the dipped beam headlamps circuit, located in the junction unit.

Functional description The headlamp alignment device H15 is supplied at pin 2 - with the dipped headlamps on - by a line coming from the steering column switch unit H5 : in involves a supply controlled by the ignition (INT/A) for the line protected by the fuse F5 for the junction unit B1 . The supply is maintained even when the main beam headlamps are switched on, through the special relay J45 ( 2888832SeeE2011DIPPED HEADLAMPS ). Pin 4 of device H15 is earthed, whilst pin 1 sends the signal to adjust the motors N30 (left) and N31 (right), through a resistance divider which alters the output voltage according to which of the four positions has been selected. Motors N30 and N31 contain a transducer that establishes actual motor travel on the basis of the voltage of an adjustment signal received by pin 2 from device H15 whilst pin 1 is earthed. Motors N30 and N31 are supplied, at pin 3, by the same line for the circuit for the dipped headlamps and the line protected by the fuse F5 for the junction unit B1 ( 2888832SeeE2011DIPPED HEADLAMPS ). The device therefore only works when the dipped headlamps are switched on.
