2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment
and the safety of the user.
Note: When unpacking or manoeuvring the searchlight into its fixing position, suitable
lifting points must be used in order to prevent damage to the equipment or personal
injury.
Because of the high internal pressure within the lamp, there is a risk of explosion in either a
hot or cold state;
During operation this lamp emits intense UV radiation which is harmful to the eyes and
skin. Suitable protection should be worn;
The high luminance of the arc can cause severe damage to the eye if viewed directly.
ALWAYS wear suitable protective goggles when viewing the lamp;
Always use protective jackets supplied with the lamp;
Should it be necessary to examine the lamp with the front bezel removed, always use a
protective shield and wear goggles to ensure a safe working environment;
Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for
cooling down after turning the searchlight off;
Never place anything on or cover the searchlight when in use;
Ensure the lamp has cooled sufficiently before removal;
If undue force appears necessary to remove the lamp, the equipment should be inspected
by a competent person or contact the manufacturer;
When disposing of lamps there are several options available:
Return the lamp, via the supplier, to the lamp manufacturer in its complete
packaging
Because of the cold internal pressure of the lamp is approximately 8 bar,
the lamp must first be depressurised before disposal. Place the lamp, in its
protective jacket, in a plastic bag and drop from a height of 1 to 2 metres
onto a hard surface;
These lamps do not contain materials which are harmful to the environment and thus are
not subject to special waste disposal regulations;
Due to the vast range of lamps available it may appear possible that more powerful lamps
can be used in the equipment than for which it was designed. Even when the unit will
physically accept a higher wattage lamp, this substitution is not recommended and is
dangerous. This action will also void any warranties on the equipment.
Always refer to the lamp manufacturer’s technical data when dealing with lamps.

5 - Electrical Installation
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1) Disconnect the supply before working on the electrical system;
2) The searchlight must be connected to a fused electrical supply, using suitably sized cable;
3) If the searchlight is located a considerable distance from the supply, provision must be
made in the cable size in order to overcome the voltage drop.
The following table below indicates the maximum length of cable to be used for the AC
supply cable:
Searchlight

10.0
1869 MTRS
4) Whenever possible cable terminations should be made below deck and with approved
terminal devices;
5) If a spare auxiliary fuse or circuit breaker is not available, one of the correct type and rating
should be fitted and connected to a positive supply. It is advisable to locate a bus bar or
main connection and avoid any direct connection to the supply:
6) For 240v AC products, the following colour coding system should be used for the customer
supply cable:
Brown - Live
Blue - Negative
Green/Yellow - Earth
Note: This equipment must be earthed.

Installation Guidelines
A typical installation and connection routine for the LX300RC searchlight is as follows:
Referring to wiring diagram C27465, a supply is fed to the power supply unit, which then
provides a common feed to the motor gearbox, searchlight and joystick panel.
The searchlight has been pre-wired with 3 metres of cable from the motor gearbox to junction
box provided. The searchlight head is pre-wired along with the connecting cable to the motor
gearbox.
Cables required to be connected by the customer: -
2 pair twisted 0.22mm 100 ohm screened cable from the joystick panel to the junction box.
5 core 1.5mm cable from the PSU to the junction box.
3 core 2.5mm cable from the PSU to the junction box.
Supply cable to the PSU.
When the light is in operation the output from the PSU should be 20v at 15 amps.
Basic Operation
When the searchlight is switched on a supply is fed to the PSU. This in turn generates a
sufficient voltage to the ignitor in order that the ignition voltage is achieved and the Xenon lamp
strikes.
After the lamp has lit, the PSU regulates the voltage through the ignitor so that the lamp
operates within its design parameters.

6 - Operating Instructions
This equipment is designed for use out of doors, in free air. Never place anything on or cover
the searchlight when in use as this may present a hazard.
The searchlight can be remotely positioned via the joystick control panel, with the facility for
movement up, down, left and right. (See Fig 1 below for aid to instructions)
To operate the panel, press panel button (1), the button will light up & the joystick (4) is now
operational. To switch the lamp on or off press the lamp button (2)
The speed of movement depends on the more pressure applied to the joystick (4) the faster the
searchlight moves. When in the desired position the joystick should be released so that it
returns to dead centre.
On remote focus models the beam of the searchlight can be adjusted to give a variety of beam
types. Using the focus button (3) on the joystick panel, the desired beam can be achieved for
any particular application. The beam will move continuously through ‘spot’ to ‘flood’. In order to
fix the beam type, simply release the focus button at the desired position.
To return the searchlight to Factory set auto home position (forward and horizontal) simply
switch off the joystick panel using the panel button (1) and then press the lamp button (2), the
searchlight will then move to the per-programed home position.
To set a new Home position, move the searchlight to the desired home position, switch off the
panel (1), move the joystick to the downward position ↓ and simultaneously press the Lamp
button (2).
There is the option for added slave panels, the slave panel has all the features of the main
control panel i.e. joystick, focus and on/off.
When the lamp is switched on, this will illuminate the Lamp button (1) on both the Main & Slave
Control panel, also when the Focus button (3) is pressed, both Focus buttons will be
illuminated.
The brightness of the panel can be increased or decreased by holding the panel switch (1)
down and moving the joystick left and right, left to decrease right to increase.

Setting to Work
Safe service in use necessitates the strict observance of the following precautions.
Any article fabricated from quartz or glass is inherently fragile and care should
therefore be taken, at all times, when handling lamps;
Eye protection must be worn when handling lamps that have been removed from
their packaging materials. The protective jacket should not be removed from the
lamp for safety reasons, as there is a remote possibility of the lamp shattering
violently, especially if it is subjected to mechanical shock or vibration;
Ensure that the power rating of the Xenon lamp to be fitted is suitable for the lamp
house and power supply equipment;
Always isolate the equipment from the supply before inserting a lamp;
Before inserting the lamp ensure that all contacts are clean. Contacts must be
renewed at the slightest sign of corrosion. Sanding or filing down corroded areas is
not recommended as this will only make the conducting surface between the pin
and lampholder smaller, thus causing the lamp to overheat;
Do not twist or bend the fused quartz bulb when fitting the lamp as mechanical
stresses MUST be avoided;
When inserting or removing a lamp, always hold it securely by its’ base in order to
prevent breakage between base and bulb;
The lampholder must not exercise mechanical tensions on the lamp, neither during
insertion or operation. Contacts must not discolour during use;
For safety reasons, the lamp should be replaced once it has reached its’ average
life, and not later than 1.25 times the stated life. With continuing use, the risk of the
lamp exploding increases due to alterations within the quartz;
Before the protective sleeve is removed, suitable protection must be worn i.e face
mask and gloves with wrist protection;
Never touch the quartz bulb with bare hands, as fingerprints will make the glass
cloudy and cause a severe loss of light. This may also cause recrystallisation and
thus weaken the bulb material. Should the bulb be inadvertently touched, remove
fingerprints with methylated spirit and a clean, soft paper towel. The bulb should
then be wiped with distilled water. NOTE: ALWAYS WEAR MASK AND GLOVES
DURING CLEANING);
All packaging and the protective sleeve must be retained for re-use. Whenever
removing a lamp, the protective sleeve must always be used for safety reasons;
In all circumstances the lamp manufacturer’s data should be referred to when dealing
with lamps.
