The lamp power and ignition system consists of the lamp power supply, lamp
base assembly, and the lamp cartridge assembly. In the event you have a power
supply failure, it is recommended that the power supply be returned to ST

supplies come up to voltage immediately. The lamp power supply has a built in
delay of 1 to 2 seconds before it will attempt to start the lamp. If the lamp is
unsuccessful at igniting, the power supply will try 6 to 10 times in rapid
succession before ceasing. After successful ignition, the supply switches to a 15
VDC output at approximately 20 amps of current.
Cooling is provided by a 100 CFM, 12 VDC fan. Air is drawn through the sides of
the unit, across the power supply and lamp, and exhausted through the rear
mounted exhaust louver. An infrared filter which is located between the lamp
lens and the lamp housing provides additional cooling of the light. This filter
blocks the infra-red "heat" from the output turret while passing the visible light,
thus lowering the temperature of the instruments and cables. Caution should still
be used as there are still potentially hazardous temperatures at the turret.
The following procedures are meant to aid the technician/engineer in replacing
defective or damaged components. These procedures are meant to be used by
qualified personnel only. Extreme caution should be used and all necessary
safety precautions taken when working on this equipment.
