PREFACE
The SEL10 is a 10,000 watt xenon searchlight mounted on a rotating yoke. The angle and direction
of light projection are independently adjustable on a 360° horizontal arc and through 90° of vertical tilt,
and locks in the desired position. The base assembly is a weathertight enclosure containing the xenon
power supplies. The unit is mounted on a trailer and powered by a diesel engine-generator unit.
Continuous high output performance is assured by means of a coated, 30 inch precision electro-
formed, parabolic nickel reflector. The reflector is carefully positioned at the factory and requires no
operator adjustment. The light source is a 10,000 watt xenon bulb which can operate in any position
(vertical to horizontal) and maintains a constant color temperature of 5600° Kelvin. A squirrelcage blower
is mounted in the lamphead to provide continuous forced-air cooling while the bulb is in operation. The
bulb is warranted for 500 hours. It is recommended to replace the bulb upon expiration of the warranty.
Operator controls mounted to the instrument panel include a SYSTEM ON/OFF switch and a STRIKE
(“emergency ignite”) switch to bypass the autostrike circuit. A FOCUS switch controls an AC motor inside
the lamphead which moves the bulb inside the reflector to adjust focus. An hour meter, located adja-
cent to the switches, records the elapsed time of xenon bulb operation. A volt meter and ammeter
monitor xenon bulb operation.
Direct current for the xenon bulb is derived from two high reactance xenon power supplies mounted
in the base of the unit. All models are designed for 50/60 Hertz operation, and are available in varying AC
input types, depending upon the confuguration of the main power transformer. Check the Equipment
Data Plate to determine the exact AC requirement prior to installation.
Coarse and fine taps are easily set to regulate the DC current to the xenon lamphead. Some models
of these power supplies have the capability of overdriving the xenon bulb; carefully check the power require-
ments specified by the bulb manufacturer and do not exceed the maximum current stated.
The two power supplies, wired in parallel, produce the high open circuit ( “no load”) voltage
required for bulb ignition, and, after ignition, the filtered low voltage current to sustain operation. The
bridge rectifiers utilize silicon diodes as the power conversion elements. The diodes are mounted to
oversize heat sinks to disperse the heat generated by normal operatrion. Internally wired squirrelcage
blowers provide additional forced-air cooling of each power supply. Thermal switches act as safety
interlocks to shut down the power supplies and protect the rectifier diodes in case temperatures reach
excessive levels.
INSTALLATION
Check all equipment Data Plates and make certain that the generator unit conforms to the
input requirements of the main transformers of the xenon power supplies. Refer to the instructions fur-
nished separately for generator start-up procedures. Set generator output to 208/230 V.AC, 60 Hz. All
output connections to the xenon power supplies and lampheads are factory prewired.
Remove the (2) end panels from the base assembly to gain access to the tap terminal boards of
the xenon power supplies. Remove the upper clamping knob (“TRANSPORT ONLY”) from the projection
angle locking arm. Loosen the (2) set screws securing the yoke position and fold the hinged plate of the
transport support mechanism down. Loosen the projection angle clamping knob and lower the lamphead
to a horizontal position. Retighten the clamping knob to secure the lamphead. Release the (4) cowl
clamps and remove the front cowl assembly.
