CHAPTER III
INSTALLATION AND OPERATIONAL CHECKOUT
NOTE
The following checkout procedures are to be performed by competent technicians.
3-1
PRE-OPERATIONAL CHECKS.
Prior to applying power to the searchlight, all cabling should
be rechecked for proper connections. Ship’s power should be off. The Power Supply circuit breaker should
be in the OFF position and the remote control panel STANDBY/ON/IGNITE switch A3S1 should be in the
STANDBY position.
3-2
LAMP IGNITION.
Place the 500 Watt searchlight in operation by performing the following
steps:
(1) Connect the ship’s power to the searchlight Power Supply by closing the disconnect located
near the Power Supply.
(2) Position Power Supply single-phase circuit breaker A1CB1 to ON.
(3) Position remote control panel STANDBY/ON/IGNITE switch A3S1 to ON or IGNITE.
NOTE
As the xenon lamp accrues hours, it may take longer to ignite in the ON or IGNITE position.
Momentarily move remote control panel STANDBY/ON/IGNITE switch A3S1 to the IGNITE
position and when the lamp ignites, release switch A3S1 immediately.
(4) Position remote control panel STANDBY/ON/IGNITE switch A3S1 to ON or IGNITE position. If
lamp does not ignite after several attempts.
(5) Check remote ammeter A4 near remote control panel A3 when xenon lamp ignites. The initial
current indication should rise to 20 - 25 amperes and remain relatively steady.
CAUTION
Wait 15 minutes before positioning circuit breaker and ship’s power to OFF.
Position remote control panel STANDBY/ON/IGNITE switch
to STANDBY and allow blower fans to cool searchlight.
(6)
If current in remote ammeter is above 25 amperes:
(a) Position ship’s power to OFF and Power Supply circuit breaker to OFF.
3-3
MANUAL-BEAM FOCUS ADJUSTMENT.
Beam limits can be set for a desired pattern by per-
forming the following steps:
(1) Open searchlight head rear cover.
(2) Remove screw and lock washer from spherical link.
