188.8.131.52. Function of detection of malfunctions
Function of detection of power failure on an entrance
If entrance tension of the control unit of a gas-discharge headlight (9–16 In) is less than norm (except for a voltage reduction right after headlight inclusion), the control unit switches off gas-discharge headlights with a view of protection.
The control unit of a gas-discharge headlight again includes headlights at renewal of giving of normal operational tension.
Failure detection function on an entrance
At deviation detection from norm on a system exit (break or short circuit in a chain of a plait of wires), the control unit switches off gas-discharge headlights.
If the control unit of a gas-discharge headlight worked because of deviations on a system exit, headlights remain switched off until the switch of external lighting will not be again established in the situation corresponding to inclusion of headlights.
