manual.

Should you ever need to contact Francis Searchlights Ltd. regarding your equipment, please

quote the Product Serial Number at all times.

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;

◼EmArc lamps operate under very high-pressure conditions (up to 200 bar) and at high

temperatures (inner bulb temp 1000°C max) and may unexpectedly shatter;

◼Lamps must not be used beyond their rated service life. Operation beyond the rated

service life will increase the likelihood of bulb rupture; fast switching cycles will reduce lamp

life.

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

eyesight from UV. 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 lid removed, always use safety

goggles or face mask and protective gloves to ensure a safe working environment;

◼Never attempt to clean the searchlight whilst in use;

◼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 (minimum 10 minutes after

switching off);

◼If undue force appears necessary to remove the lamp, the equipment should be inspected

by a competent person or contact the manufacturer;

◼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.

◼In the event of a bulb rapture, a limited amount of mercury vapour could be emitted. To

avoid inhaling this mercury vapour (which is toxic and can be harmful for lungs and

nervous system) using a mask remove the front bezel from the searchlight and ventilate

thoroughly for a period of at least 30 minutes.

◼At the end of rated life, when lamp is removed from service, please dispose of in

accordance with local universal waste law (Lamps are stamped with Hg mark). Some areas

require all mercury containing lamps to be recycled, contact your environmental

department for any regulation that may apply.

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. When in the desired position fasten 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. If no cabling is required to be seen

on deck, there is the option to wire from underneath the base directly into the deck. See

drawing A7180 for details.

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) The junction box should NOT be positioned more than 30 metres away from the searchlight

using standard cables supplied.

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:

Note: This equipment must be earthed.

Installation Guidelines

A typical installation and connection routine for the VM500RC searchlight is as follows:

Referring to wiring diagram C27386, a supply is fed to the junction box which then provides a

common feed to the searchlight and joystick panel.

The following cables have been supplied as standard: -

4 metres of 2 pair twisted 0.22mm screened cable from the junction box to searchlight.

4 metres of 3 cores 1.5mm cable from the junction box to the mains supply.

4 metres of 7 cores 1.5mm cable from the junction box to searchlight.

4 metres of 2 pair twisted 0.22mm screened cable from the junction box to the joystick panel.

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.

Switch On

The panel is activated using the PANEL button. This will illuminate brightly when the panel is

active. Alternate operations of the PANEL button will switch the panel on and off.

Lamp Control

When the panel is active pressing the LAMP, button will switch the lamp on or off.

If the control panel is switched off with the PANEL button the lamp will switch off.

Focus Control

The lamp focus can be adjusted using the FOCUS button. Lamp focus will adjust continuously

whilst FOCUS is pressed.

Beam Direction

The beam direction can be adjusted using the joystick when the panel is active. Moving the

joystick left or right will pan the beam clockwise or anticlockwise.

Moving the joystick up or down will move the beam up or down. The speed of movement is

proportional to the movement of the joystick. It is possible to move the beam in both directions

at once by moving the joystick diagonally.

Home

The lamp can be returned to a pre-set home position. By default, this is dead ahead with the

beam level although different positions can be programmed as described below.

To send the lamp to the home position switch the panel off then press the LAMP button.

Set New Home Position

To set a new home position move the lamp to the new desired home position. Switch the panel

off then press the joystick down to its limit and press the lamp button. The current position will

now be the new home position.

Set Motion Limit (only available when Remote Focus is fitted)

The lamp travel can be limited in either axis and either direction. To set a new limit switch the

panel on and move the lamp to the desired limit position. Switch the panel off then press and

hold the focus button whilst moving the joystick full travel in the direction of the desired limit.

Hold in this position for 4 seconds. For example, to set a limit to the tilt up motion; -

1. Switch panel on and drive lamp to desired tilt up limit position.

2. Switch panel off.

3. Press and hold the FOCUS button and hold joystick in the full up position for 4

seconds.

4. Tilt up motion will now be inhibited above the current position.

Clear Motion Limits

Motion limits as set above can be cleared by switching the panel off then pressing and holding

the focus button and lamp buttons together for 10 seconds.

Adjusting Panel Illumination

The panel illumination and indicators intensity can be adjusted to suit ambient light levels. To

adjust the intensity, switch the panel on then switch it off with the PANEL button and keep the

PANEL button pressed. To increase intensity, move the joystick to the right. To decrease move

to the left. Note that the panel button must be kept depressed whilst the joystick is moved. All

indicators will illuminate whilst adjustments are performed. Adjustment is complete when the

panel button is released.

Obtaining Fault Status

Fault codes can be accessed by switching the control panel on with the PANEL button and

keeping the PANEL button pressed for 10 seconds. Fault codes are indicated by the PANEL

button flashing a number of times related to the fault. Fault codes are detailed below. If more

than one fault is present the PANEL button will indicate them in sequence.

1. Pan Limit. –Either of the pan limit switches operated. Note that this

may not actually be a fault. The LED will flash when a limit switch is

operated under normal circumstances i.e. the lamp is at the limit of

travel. This will also indicate when a variable limit is reached.

2. Tilt Limit. –Either of the tilt limit switches operated. Note that this may

not actually be a fault. The LED will flash when a limit switch is

operated under normal circumstances i.e. the lamp is at the limit of

travel. This will also indicate when a variable limit is reached.

3. Pan motor over current. –The pan motor is taking excessive current.

The motor will be disabled for a period when this occurs. Fault

indication will remain until power is removed or the fault is corrected.

4. Tilt motor over current. –The tilt motor is taking excessive current. The

motor will be disabled for a period when this occurs. Fault indication

will remain until power is removed or the fault is corrected.

5. Focus motor over current. –The focus motor is taking excessive

current. The motor will be disabled for a period when this occurs. Fault

indication will remain until power is removed or the fault is corrected.

6. FBUS interface over current. –The speed control card supplies 24VDC

to the remote-control panels. This fault indicates the 24VDC output is

taking excessive current. The FBUS supply output will switch off. To

restore this output, remove the supply from the speed control card for a

period.

7. Anti-condensation heater output over current. –The 24VDC anti

condensation heater output is taking excessive current. The heater

output will switch off. To restore this output, remove the supply from the

speed control card for a period.

8. Limit Switch Error. Some lamp types do not use all or some limit

switches. If an invalid limit switch input is detected it is probable the

speed control card is set to the wrong product or there is a wiring error.

9. Datum Error. The start-up datum system has not completed correctly.

10.Product type not set or corrupt. The product type has not been set, has

been set incorrectly or is corrupt.

11.Supply voltage out of tolerance. The 24V supply is outside the range

18-30V.
