Strong Enterprises FOLLOW SPOTLIGHT 48057 - Manual (Page 20)

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 RF 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. 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; 140-170
V.DC if using a switching type. If this voltage is not indicated, the problem is in the leads between the lamp-
house and power supply, or in the power supply boost circuit. See the trouble shooting section of the power
supply manual for additional instructions.
THE SWITCHING-TYPE xenon power supply normally furnished with the spotlight system
contains thermal overload switches and circuits to protect the power supply from high or low AC input voltage.
A lack of open circuit voltage, or interruptions in sustaining DC current, may be traced to these circuits.
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, power supplies) between similar Strong Xenon
Troupers to aid in diagnosis of a problem is encouraged. This will not lead to equipment damage, and will not
void equipment warranty.
