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.

Prevent rain, snow, condensation and water droplets from contacting the lamp as this may

cause bulb failure and possible shattering;

Quartz halogen bulbs run with a high internal pressure in excess of atmospheric. Whilst the

construction is inherently strong, there is a slight risk of the bulb shattering;

Never look directly into an illuminated searchlight as this may cause severe damage to

eyesight. If it is necessary to inspect a lamp whilst in operation, always wear suitable

protective goggles;

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;

Never attempt to clean a lamp whilst in use;

Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for

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 breaking a lamp for disposal, care must be taken to ensure the glass fragments are

safely contained. This operation must be performed out of doors in free air. In all

circumstances refer to the lamp manufacturers instructions packed with the lamp;

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 or voltage lamp, this substitution is not recommended

and is dangerous. This action will also void any warranties on the equipment.

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

Note: ~

When the main power is first applied to the searchlight, the searchlight will carry out a

self-test, it will Pan to the left limit and Tilt down to the limit, once this is complete, the

searchlight will then move to the centre and horizontal, during this please do not try and

operate the searchlight while this test is being carried out. Once the searchlight is back

at centre the searchlight can then be operated normally, by pressing the Panel button on

the control panel.

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, from the control panel to the searchlight:

Note: This equipment must be earthed.

Installation Guidelines

A typical installation and connection routine for the L560RC searchlight is as follows:

Referring to wiring diagram C27425 a supply is fed to the junction box which then provides a

common feed to the motor gearbox, searchlight and joystick panel.

The searchlight has been pre-wired with 3 meters 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.

Supply cable to the junction box.

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 pre-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.

When fitting the lamp:

-Always isolate the equipment from the supply when inserting a lamp;

-Ensure the circuit is suitably fused;

-Ensure the lamp is of the correct power rating and type;

-Check lampholder is in good condition. If the contacts show any sign of corrosion, replace

the lampholder;

-Check the lampholder is in a good dry condition. Never allow water to collect in the lamp

fitting or come into contact with the lamp.

To fit the lamp:

-Remove the front bezel assembly by operating the safety catch and lifting the latch body;

-For easier access the light shield/spill ring may be removed by undoing the fasteners;

-Position the two pins above the holes in the lampholder;

-Gently push the lamp into the lampholder;

-Replace the light shield/spill ring and front bezel assembly, ensuring the safety catch is

engaged.

Testing

Upon correct installation and connection to an electrical supply, the equipment can be tested in

order to ensure its’ correct performance. A competent person with some knowledge of electrical

equipment must carry out this work.

Equipment required: Multi-meter with leads

Ammeter

Using the equation P=VI, the approximate power output of the equipment can be calculated in

the following way:

-Using the multi-meter, take a voltage reading across terminals 3 & 7 in the searchlight;

-Using the ammeter, take an amp reading from the live cable to the lamp;

-Multiply these figures together to give an approximate wattage (Power output).

For example:

Using a 240v 2000w Tungsten halogen lamp:

Voltage reading = 240v; Amps reading = 8.3 amps

Therefore, Wattage = 240 x 8.3 = 2000 watts
