DIPPED HEADLIGHTS - DESCRIPTION

DESCRIPTION

The vehicle is equipped with two dipped headlamps in the lights. The headlamps are switched on by the steering column switch unit by turning the ring nut to the position after the side lights.

A special relay, located in the junciton unit under the dashboard, controls the engagement of the dipped headlamps via two lines protected by special fuses. The relay for engaging the dipped headlamps is managed by the Body Computer. relay energizing is activated by enablement signals with the TEG inserted (INT) and from the specific signal from the steering column switch unit.

With the dipped headlamps on, the simultaneous presence of the main beam and fog lights commands disables the dipped headlamps. The subsequent deactivation of one of these two commands, with the dipped headlamps control still on, involves the dipped headlamps being turned back on.

The dipped headlamps can be automatically activated by means of the dusk sensor, if the AUTO function is set on the steering column switch unit. The dusk sensor is an infrared device that works at different sensitivity settings: when the dusk sensor is activated a message is shown on the instrument panel display indicating the sensitivity setting (from 1 to 3): this setting can be adjusted using the "Mode +" and "Mode -" buttons.

The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (TEG extracted) for a period of 30 seconds or multiples thereof. The "dipped headlamps" warning light in the instrument panel signals that the lights have remained on.

It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the TEG being extracted: each time the lever is operated the length of time the lights remain on is increased by 30 seconds, up to a maximum of 210 seconds. Inserting the TEG or keeping the flasher lever pulled for more than 2 seconds eliminates the function.

Gas discharge headlamps

DESCRIPTION

The vehicle is fitted with two GAS DISCHARGE headlamps.

The electronics built into each of the two headlamps switch them on and off according to the times defined by the software and, in accordance with international regulations, the gas discharge bulbs too. The system comprises an igniter located in the base of the bulb and a ballast located in the bottom part of the lamp.

The left lamp is the master control unit, whilst the right one performs a slave role.

The master lamp acquires the command for the dipped headlamps, the vehicle speed and from the potentiometers located on the wheel axles. Depending on the inputs, it directly controls the switching on of the left front headlamp (dipped headlamps) and controls the right one in a similar way via the serial line.

The dipped beams are activated by turning a wheel on the stalk switch to the next position after the side light setting.

A relay in the underfacia control unit controls activation of the low beams via two lines protected by specific fuses.

The low beam activation relay is controlled by the Body Computer relay energizing is activated by enablement signals with the TEG inserted (INT) and from the specific signal from the steering column switch unit.

With the dipped headlamps on, the switching to main beams causes the shutter in gas discharge bulb to be raised with a switch to main beams.

The dipped headlamps can be automatically activated by means of the dusk sensor, if the AUTO function is set on the steering column switch unit. The dusk sensor is an infrared device that works at different sensitivity settings: when the dusk sensor is activated a message is shown on the instrument panel display indicating the sensitivity setting (from 1 to 3): this setting can be adjusted using the "Mode +" and "Mode -" buttons.

The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (TEG extracted) for a period of 30 seconds or multiples thereof. The "dipped headlamps" warning light in the instrument panel signals that the lights have remained on.

It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the TEG being extracted: each time the lever is operated the length of time the lights remain on is increased by 30 seconds, up to a maximum of 210 seconds. Inserting the TEG or keeping the flasher lever pulled for more than 2 seconds eliminates the function.
