126.96.36.199. Function of detection of malfunctions
Function of detection of power failure on an entrance
If the entrance tension of the control unit of a gas-discharge headlight (9–16 V) is less than norm (except for undervoltage right after inclusion of a headlight), the control unit switches off gas-discharge headlights for protection.
The control unit of a gas-discharge headlight includes headlights again at renewal of giving of normal operational tension.
Function of failure detection on an entrance
At detection of an aberration at the 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 at the exit of system, then headlights remain switched off until the switch of external lighting is not installed in the situation corresponding to inclusion of headlights again.
