TROUBLE SHOOTING (continued)
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 the
"No Load" DC voltage between the lamphouse and power supply. Measure the DC voltage across
terminals J1-1 (+) and J1-2 (-). DO NOT measure voltage across the bulb end caps. A reading of
130-170 V.DC should be measured. If this voltage is not indicated, the problem is in the leads between
the lamp h ouse and power supply, the MS connectors, or in the power supply boost circuit. See the
trouble shooting section of the xenon power supply manual for additional instructions.
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, re p lace 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, and DC
"no load" voltage exceeds 130 V.DC, the problem is in the igniter assembly.
EXCHANGE of components (i.e. igniters, igniter PC boards) between similar Strong
Xenon Super Troupers to aid in diagnosis of a problem is encouraged. This will not lead to equip-
ment damage, and will not void equipment warranty.
THE STRONG DC PULSE IGNITER STORES ENERGY IN ITS
CAPACITORS AFTER THE UNIT HAS BEEN DE-ENERGIZED.
TO PREVENT SHOCK, THIS ENERGY CAN BE DISCHARGED
BY PLACING THE BLADE OF AN INSULATED-HANDLE
SCREWDRIVER ACROSS THE TIPS OF THE TWO SPARK
GAP SCREWS MOUNTED TO THE IGNITER PC BOARD.
