Strong XENON SUPER TROUPER, Instruction Manual

Page: 28 / 58

TROUBLE SHOOTING (continued)
THE VANE on the air flow switch should raise. With the MODE switch in the “MAN.”
position and the LAMP switch in the “ON” position, the running time meter should start and indicate
elapsed time. If this meter does not operate, check for continuity at the MODE and LAMP switches.
A DEFECTIVE RUNNING TIME METER will not prevent bulb ignition.
WITH THE “LAMP” SWITCH in the “ON” position, a distinct high voltage arc ping
should be heard at the spark gap in the igniter, and the flash of the xenon bulb should be visible through
the ammeter as a high DC voltage pulse is applied across the bulb electrodes.
IF THE HIGH VOLTAGE PING or the flash at the ammeter is not apparent, check for
115 V.AC at terminals 5 & 6 at the igniter terminal board. If 115 V.AC is present, and terminals are
tight, check then the “No Load” DC Voltage between the lamphouse and power supply. Remove
either lead #5 or #6 at the igniter terminal board to prevent bulb ignition and defeat the cover interlock
switch. Check the DC voltage across terminals #10 (-) and #15 (+). A reading of 85-150 V.DC should
be measured if using a high reactance power supply; 120-170 V.DC if using a switching type. If this
voltage is not indicated, the problem is in the leads between the lamphouse and power supply, or in the
power supply boost circuit. See the trouble shooting section of the power supply manual for addi-
tional instructions. Replace lead #5 or #6 at the igniter before proceeding.
IF THE HIGH VOLTAGE ARC is audible at the lamphouse and the bulb does not
flash, check for a lamphouse DC lead arcing to ground. If no ground fault is detected, replace the bulb
and attempt ignition with the new bulb.
IF THE HIGH VOLTAGE ARC is audible at the lamphouse, the flash of the bulb is
visible in the ammeter, but ignition of the bulb is not sustained, the problem area is in the power supply.
See the trouble shooting section of the power supply manual for additional instructions.
IF THE HIGH VOLTAGE ARC is not audible or the flash of the bulb visible, the
problem is in the igniter assembly.
EXCHANGE of components (i.e. igniters, printed circuit boards) between similar Strong
Xenon Super Troupers to aid in diagnosis of a problem is encouraged. This will not lead to equipment
damage, and will not void equipment warranty.
CAUTION - HIGH VOLTAGE
THE IGNITER SPARK GAP (SEE FIGURE 3, ITEM 7) MUST
BE SHORTED OUT WITH AN INSULATED HANDLE
SCREWDRIVER BEFORE SERVICING OR BENCH TESTING
THE IGNITER.
