Strong International XENON GLADIATOR IV, Instruction Manual

Page: 11 / 48

OPERATION
OPEN THE BOOMERANG ACCESS COVER and verify that the round glass heat filter and
ring assembly is installed into the bracket mounted to the fadeout and douser support housing. NOTE: The
coated side
of the filter, with the XX or other marking,
must be facing the reflector
.
REMOVE THE PLASTIC COVER from the xenon bulb. DO NOT ignite the lamp with the
cover on the bulb. Store the cover for future re-use. Replace and secure the bulb enclosure covers.
CLOSE THE LAMPHOUSE COVER and secure using both latches. Turn on the main line
switch and/or circuit breaker to energize the xenon power supply. The spotlight blowers will start and operate
continuously until the xenon power supply is de-energized.
PLACE THE LAMP
SWITCH in the “ON” position and the lamp will ignite. Check the
reading on the lamphouse ammeter. Nominal current for the 4500 watt xenon bulb is 135 amperes. If using
a lower wattage bulb, check the documentation packaged with the bulb for its current ratings. DO NOT, AT
ANY TIME, exceed maximum rated amperage;
the “wattage” readout on the digital display is an approximate
figure and should not dictate the output setting
. Output current is adjusted at the xenon power supply; see power
supply manual for instructions. Operation of a new bulb is normally started at the lower end of its range, and
current is gradually increased as the bulb ages to maintain light output. During the ignition cycle, the display
will also briefly indicate the high “no load” (open circuit) DC voltage applied to the xenon bulb for ignition.
REMOVE THE REAR COVER above the instrument panel by releasing the (3) quarter-turn
fasteners. This exposes the bulb positioning controls in the lamphouse back casting. To focus the xenon bulb
and obtain the best light on the stage, the two methods outlined below are the most suitable.
MOVE THE SPOT SIZE CONTROL HANDLE (trombone) on the large lens carriage all the
way forward to project the smallest spot possible; place the iris, masking shutters (choppers) and the fadeout
douser blades in their full open positions. Project a spot to a wall or similar flat perpendicular surface opposite
the spotlight position.
XG4/009
THE CENTER SECTION of the bulb
positioning controls is a threaded member that
focuses the bulb in relation to the reflector. Turning
this adjustment moves the bulb in only one plane,
into or away from the reflector. Turning this section
clockwise moves the arc away from the reflector.
The small knurled screw to the left of this section can
be tightened to lock the focusing mechanism after
the following procedures have been completed.
THE LARGE THUMB SCREWS, on
either side of the focusing control, lock the
horizontal and vertical adjustment mechanism
in position.
