Light flickering Check Are abnormal wiring conditions at fault Has the system reached the normal end of life Are the lamp, power coupler and generator compatible Is the generator operating correctly Is the line voltage correct Are the lamp, power coupler and generator compatible Is the system temperature high yes yes no no no yes yes Action Correct abnormal condition(s) and check for normal operation. Replace the system and check for normal operation. Replace the incorrect component(s) and check for normal operation. Replace faulty generator and check for normal operation. Correct the supply voltage to within the specified tolerance or correct tap connection. Correct abnormal condition(s) and check for normal operation. Check temperature conditions and system mounting. See reference (A) (B) (C) (D) (E) (F) (F) Problem solved no Contact experts for further problem solving at info<strong>QL</strong>@philips.com. 36
Reference (A) Lamp base to power coupler contact Faulty wiring Good contact between the lamp base and the power coupler is essential. The lamp is attached to the fixture by the power coupler only, check to see if the lamp is mounted on the power coupler correctly. Check all 5 connections (ground, mains input, HF-output) on the generator for correct wiring, loose contacts, poor connections, or broken wiring. All generators must always be grounded. Generators and components may be grounded to the fixture or otherwise connected to the ground. It is hazardous and possibly fatal for a human to make contact with an ungrounded fixture, generator or other electrical component while it is in operation. Coaxial cable The coaxial cable of the power coupler may not be crushed, i.e. the bending diameter is limited. The distance between the (coaxial) generator output cable and the generator input leads (mains cable) should be as big as possible, but at least 10cm (~4 inch). The wire and plug-in connectors between the power coupler and generator must not be altered in any way and must be kept away from the surface of the lamp. Power coupler cooling <strong>QL</strong> lamps are restricted to an optimum operating temperature. For example, lamp and power coupler should be firmly attached on a heat sink with 4 bolts with a prescribed diameter, length and material. Otherwise, the lamp may produce low light output or fail early. The generator and power coupler are not mounted on a shared heat sink. Generator cooling Lamp damage due to handling or shipping The bottom of the generator is mounted flat against a large metallic surface of the fixture for good heat transfer. The generator and power coupler are not mounted on a shared heat sink. Damage to the system from handling or shipping may cause a crack in the glass or broken wires. 37
