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) 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 front bezel removed, always use
safety goggles or face mask and protective gloves 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
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.

Installation Guidelines
A typical installation and connection routine for the VM330 RC 240v supply searchlight
is as follows:
Referring to wiring diagram C24077, a supply is fed to the junction box (control devices), which
then provides a common feed to the searchlight and joystick panel.
The searchlight to junction box has been pre-wired with 3 meters of 12cores 0.5mm and
3 cores 2.5mm cable. The only cables that need to be supplied by the customer are the
12 cores 0.5mm cable from the joystick panel to the junction box and the mains cable
Optional Slave Panel Wiring
12 cores 0.5mm2 cable from the Slave Panel to the Junction Box.
NOTE both panels MUST NOT be operated simultaneously as this may damage the
equipment
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.
The pan speed can be adjusted using the potentiometer mounted on the joystick panel. The
movement increases from 2 to a maximum of 20/sec when turned clockwise. The tilt speed
runs at 10/sec and cannot be adjusted.
The beam of the searchlight can be adjusted to give a variety of beam types. Using the yellow
remote focus button 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 button at the desired position.
The heaters specified on this equipment are self-regulating and will shut off when they reach
the dew point temperature.
There is the option for added slave panels, the slave panel has all the features of the main
panel i.e. joystick, speed control focus and on/off.
NOTE both panels MUST NOT be operated simultaneously as this may damage the
equipment
This product should not be used for any purpose other than for which it was designed.
Any modifications to the product should not be undertaken without consulting the
manufacturer.
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;
The following safety equipment must be worn when handling lamps eye protection
i.e. safety goggles or full-face mask and safety gloves;
Always isolate the equipment from the supply before inserting a lamp;
Do not twist or bend the fused quartz bulb when fitting the lamp as mechanical
stresses MUST be avoided;
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);
In all circumstances the lamp manufacturer’s data should be referred to when dealing
with lamps.
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 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:
- Loosen all the socket screws on the front of the searchlight, remove the bezel and glass
and store in a safe place;
- Fit the rear lampholder lead over the thread of the lamp and then screw into the rear
lampholder;
- Fit the front lampholder lead over the thread of the lamp and fasten in place using the nut
supplied with the lamp;
- Replace the front bezel and glass, ensuring the socket screws are securely fastened.
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 from the terminal block inside 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 350w Em Arc lamp:
Voltage reading = 240v; Amps reading = 1.45 amps
Therefore, Wattage = 240 x 1.45 = 350 watts
