TROUBLESHOOTING (continued)
Xenon Bulb Fails to Ignite; Blowers Operating,
GO
Indicator glowing
1. Defective or expired xenon bulb. Replace as required.
2. Incorrect igniter printed circuit board. Strong AC type igniters should be connected to high
voltage igniter PC board (Part No. 40913, 65992B, or equivalent).
3. Check DC no load output voltage. Should measure 150 - 180 V.DC; if lower, consult factory.
4. Faulty DC output connection. Check and correct as required. Tighten connections securely.
5. No DC voltage output. Blown fuse on primary board; allow power supply twenty minutes (power
OFF) to discharge capacitors before removing fuse. Good fuse should measure 0 Ohms; replace
as required. If fuse blows repeatedly, consult factory.
6. Defective igniter. Allow unit to cool and attempt re-ignition. Check DC voltage at output;
should measure 150 V.DC or higher. If voltage is correct, check DC connections in lamphouse
and power supply; tighten securely. Attempt re-ignition; if no ping is audible in the lamphouse,
replace igniter. If ping is audible, but no flash is apparent, check for lamphouse DC lead shorting
to ground. If ping is heard and arc is visible between bulb electrodes, and bulb fails to ignite,
replace bulb.
Xenon Bulb Goes Out During Operation (Intermittent Operation)
1. Defective or expired xenon bulb. Replace as required.
2. Fault in lamphouse interlock circuit (loose access door, inadequate exhaust draft). See lamp-
house manual.
3. Power supply overheated. Check for blower operation and unobstructed air flow in power
supply enclosure. Thermal switches will open if heat sink temperatures exceed 175° Fahrenheit
(80° Celsius).
4. Brown-out (voltage drop) or spike (voltage surge) in AC supply. Measure AC source.
No Output Current Adjustment
1. Defective power module. Consult factory.
Xenon Power Supplies, Lamphouse Igniters, and other components shipped to the
factory for credit, repair or repair/exchange must be returned through an authorized
Strong International Equipment Dealer. Contact your Strong International Dealer
