GF82.15-P-0002GH Headlamp Cleaning System (HCS), Function
- with CODE (600a) headlamp cleaning system







Function prerequisites:
- Circuit 15 ON

Function
- The headlamp cleaning system is switched on by pressing the SRA [HCS] switch (S4/1) .
- The corresponding input of the Extended Activity Module (EAM) (N10/1), which receives the input from the switch, sends the signal to relay 5 (F2k5) .
- The relay switches circuit 30 , for a duty cycle of approx. 1 second, through to the HCS pump (M5/2).
- The HCS pump (M5/2) builds up pressure in the washing water line.
- The water pressure acts against the return springs of the telescopic nozzles.
- The telescopic nozzles extend and spray washing water onto the headlamp glass.
- After the duty cycle, the pressure in the washing water line drops again and the telescopic nozzles move back to their starting position due to spring load.

Pressing the SRA [HCS] switch (S4/1) again during an ongoing headlamp cleaning cycle has no effect. A further cleaning cycle can only be initiated after the previous cycle has ended.
