XENON TROUPER TROUBLESHOOTING
Bulb fails to ignite.
1.MODE switch S3 set to “AUTO.” Place in “MAN.” position when not employing automated or remote lamphouse operation.
2.AC power not on to lamphouse. Turn switching power supply 30 A. circuit breaker ON. If 115 V.AC not read at 2 & 4, see power supply manual.
3.Top cover or side access panel interlock switch (S1, S5) open. Close and secure lamphouse top cover. Tighten all four mounting screws; check switch actuating screw. Tighten side access panel screws.
4.Faulty interlock switch(s). Check for 115 V.AC at 9 & 12; replace switch(s) if defective.
5.Faulty S2
Bulb fails to ignite; ping audible, bulb flash visible.
1.Inadequate DC output from xenon power supply. Set power supply output to correct range required for bulb wattage (65 A. for 1.6 kW, 75 A. for 2 kW).
2.If bulb flash is visible but faint, check for defective glass capacitor 65216 in igniter (capacitor body cracked or leaking oil). Replace if defective.
3.Faulty or expired xenon bulb. Replace as required.
Bulb fails to ignite; ping audible, no bulb flash.
1.Faulty xenon bulb. Check for cracked electrodes or darkened envelope. Replace if defective.
2.Ignition pulse shorting to ground. Inspect DC leads for burned insulation; dress leads away from grounded metal components.
No high voltage ping audible; MODE switch in “MAN.” and LAMP switch in “ON.”
1.Loss of AC control voltage. Check xenon power supply for tripped circuit breaker or open thermal switch. See power supply manual.
2.Little or no DC “No Load” voltage. Measure DC “No Load” voltage at 10 & 15. See power supply manual.
3.Open fuse F1 (600 V.) on switching power supply. SEE POWER SUPPLY MANUAL. Allow (20) minutes for capacitor discharge before replacing.
4.Faulty igniter. Check for adequate DC “No Load” at 10 & 15. If present, and igniter does not fire, replace igniter.
Bulb goes out during operation.
1.Xenon power supply overheated; thermal switch open. Check power supply blower(s), air inlets and outlets unobstructed. See power supply manual.
