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.

4 - Unpacking and Installation Instructions

The following instructions should be read and fully understood prior to installing the equipment

to ensure that the correct procedures are followed, and all safety precautions are observed.

Note: If the equipment has been in storage for a considerable amount of time, it is

advisable to conduct a routine maintenance check on all parts before installation.

Safety Precautions

This equipment should not be connected to an electrical supply before being installed.

Installation procedures should be adhered to in order to ensure a safe working environment

and reduce the risk of damage or personal injury.

Preparing the Mounting Position

Mark out and drill the fixing holes through the deck (refer to drawing C21501). If anti-vibration

mounts are to be fitted, the fixing holes for the mounts should also be marked out and drilled.

Prior to manoeuvring the searchlight into its’ fixing position, the AV mounts should be fitted to

the base. When in the desired position, bolt the searchlight firmly down. On an uneven surface

it may be necessary to use a suitable sealant such as silicone, in order to ensure a

weatherproofed joint.

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:

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.
