XC70 AWD L6-3.2L VIN 98 B6324S (2009)
There is normally a 3 second delay between activation with the light switch or ignition on and the Bi-Xenon lamp coming on.
-
As with normal headlamps, Bi-Xenon lamps remain off while the engine is cranking and come on once the engine is running.
-
Each time voltage is supplied to the ballast (from the central electronic module (CEM)), 3 1-second attempts are made to light the Bi-Xenon lamp.
Safety
-
In the event of a short-circuit on the high voltage side, the power supply is cut off for less than 10 ms.
-
If the high voltage circuit is broken (such as due to an open circuit, defective bulb or no bulb in the lamp socket), during each activation the system
attempts to light the lamp for a period of 700 ms. During the period, there is high voltage across the ballast.
-
Approximate component temperatures during operation: Ballast = 130 °C (266 °F), Lamp holder = 170 °C (338 °F), Bi-Xenon lamp = 400 °C
(752 °F).
-
The glass body of the Bi-Xenon lamp is filled with various gases and metal vapors and is under pressure. Because the lamp is subjected to gas
pressure, it could explode.
Warning!
-
Follow the safety instructions and recommendations in VIDA carefully when working with high voltage.
-
Use safety goggles when handling the bulb. Risk of explosion!
-
The electrical system must be switched off before starting work.
-
Risk of burn injury. The components operate at very high temperatures.
