Strong XENON GLADIATOR II Instruction Manual page 13

THESE ADJUSTMENTS should not be disturbed until it is necessary to replace the xenon
bulb. At that time, the procedure on obtaining a smooth, round black spot, or "hot spot," may have to be
repeated. Replace the cover plate over the bulb positioning controls.
BECAUSE OF NORMAL BULB AGING, and manufacturing tolerances between individual
xenon bulbs, it may be necessary to operate lamps at slightly higher or lower current settings to maintain
uniform light output when two or more spotlights are used in one installation. This entails a slight current
output adjustment at the xenon power supplies. See the power supply manual.
TO EXTINGUISH the arc, place the LAMP switch on the instrument panel to "OFF." The
lamphouse blowers will continue to operate until the xenon power supply is de-energized. Allow the blowers to
operate for ten minutes before turning off the power supply; a forced-air bulb cooling cycle is required by all
bulb manufacturers.
DAILY OPERATION in the "Manual" mode requires only that the xenon power supply be
energized, the MODE switch be left in the "MAN." position, and the lamp switched ON and OFF by means of
the LAMP switch. No bulb alignment or "warm up" are necessary. Always allow for the ten minute bulb
cooling cycle.
OPERATION IN THE "AUTO" MODE is intended for use only if the spotlight is to be used as
a fixed spot without an operator at the equipment. Place the MODE switch in the "AUTO" position, and the
LAMP switch to "ON." The lamp will ignite when a sustained dry contact is made between the automation
leads 3 and 6, and extinguish when the contact is opened. See the INSTALLATION DIAGRAM in the power
supply manual. The lamphouse blowers will operate until the xenon power supply is de-energized; allow for ten
minutes bulb cooling.
BEFORE OPENING the lamphouse enclosure for servicing, allow the blowers to operate for
twenty minutes, or until the bulb has cooled to room temperature.
GENERALLY THE BEST POSITION for the operator to stand is hear the center of the spot-
light on the right side. The angle of tilt, the size of the porthole, and the layout of the spotlight position may
dictate another location.
EACH OPERATOR will, after a few minutes of operation, generally develop his own system
and position for most convenient operation.
THE HORIZONTAL SWING and vertical tilt are individually adjustable to give the desired
degree of friction to suit the operator. The locking clamps are located on the right side of the yoke assembly.
THE EASE with which the spot size control handle ("trombone") can be operated may be
adjusted by means of the nylon friction brake screw in the outrigger of the large lens carriage casting. To access
this adjustment, open the color boomerang and remove the gel frames. Slide the large lens carriage to the
extreme rear position. Reach through the boomerang housing and loosen the nylon friction screw locknut. Turn
the nylon friction screw clockwise to increase drag, or counterclockwise to relieve. Tighten the locknut after the
desired adjustment is reached.
