Strong XENON SUPER TROUPER, Instruction Manual

Page: 27 / 58

TROUBLE CHART
NORMAL OPERATION
WHEN THE SWITCH in the main AC supply line to the xenon power supply is in the
ON position, and the 30 A. circuit breaker on the switching power supply is ON, the POWER light on
the xenon power supply will glow. The lamphouse blower will start. The blower in the power supply,
if an older high reactance type (61000, 61001) or current production switching type, will operate.
OPERATION OF THE LAMPHOUSE BLOWER will close the air flow interlock
switch, and if the lamphouse top cover and access panel are correctly installed, the control circuit to
the LAMP switch will be completed.
THE MODE SWITCH, located on the lamphouse instrument panel, should be in the
“MAN.” (manual) position. This is the normal setting for spotlight opertion, as it allows direct igni-
tion control by the operator.
WHEN THE “LAMP” SWITCH is placed in the ON position, the AC control circuit in
the lamphouse will energize the power supply circuitry providing DC current to the igniter and bulb.
THERE WILL BE a distinctly audible high voltage arc ping at the igniter arc gap and
across the bulb electrodes. The bulb should ignite immediately after one or two of these high voltage
pulses, and the lamp current will adjust to the output setting of the xenon power supply. Multiple
ignition pulses prior to bulb ignition normally indicate a low DC output setting. See xenon power
supply manual. A “warm” or aged xenon bulb might also require multiple strikes.
TROUBLE SHOOTING
IF THE XENON BULB does not ignite, observe the following operational sequences
for assistance in locating and isolating the trouble area.
WHEN THE FAN(S) and the indicator light on the power supply are on, the AC
circuit in the power supply is trouble free up to the terminal block in the power supply.
AT THIS TIME, the lamphouse blower should operate. If this does not occur, the
trouble is in the cover interlock switch, the access panel interlock switch, the blower motor, a loose
connection, or a broken #2 or #4 lead. CAUTION: To prevent bulb ignition when checking the AC
control circuit in the lamphouse, remove lead #10 from the igniter terminal strip. Check at this time
for 115 V.AC Control Voltage at the cover interlock switch (wires 2 & 4), the side access panel
(wires 13 & 14), and the blower terminals (9 & 12). The cover interlock switch must be manually
actuated to energize the blower. Replace #10 lead before proceeding.
