GDL Bulbs (2005-2009): Function: Safety
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.
- 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), Bulb holder = 170 °C (338 °F), Bulb = 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 appropriate diagnostics tool 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.
