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, 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. 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, to ensure a weatherproofed joint.
Please refer to the drawing C29556 for the Joystick Panel cut out size, which you can find at the
back of this manual.

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.
Referring to wiring diagram C28381 (at the back of the manual), a supply is fed to the driver 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 driver 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 100ohm screened cable from the joystick panel to the driver box.
•Mains supply cable to the driver box.
3m of cable supplied by

To obtain the maximum light output from the searchlight, it is essential that the full operating
voltage of the LED fitted be applied to the LED contacts.
Method of Electrical Connection
•Disconnect the supply before working on the electrical system.
•The searchlight must be connected to a fused electrical supply, using suitably sized cable.
•If the searchlight is located a considerable distance from the supply, provision must be
made in the cable size to overcome the voltage drop.
The following table below indicates the maximum length of cable to be used for the supply cable,
from the mains supply to the driver box.

•Whenever possible cable terminations should be made below deck and with approved
terminal devices.
•If a spare auxiliary fuse or circuit breaker is not available, one of the correct type/ratings
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.
•For 115/240v 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.

6 –Start-up and Operating
Start-Up
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 1/0 button on the control panel.
Operating
Switch On
The panel is activated using the 1/0 button. This will illuminate brightly when the panel is active.
Alternate operations of the 1/0 button will switch the panel on and off.
Lamp Control
When the panel is active pressing the LIGHT button will switch the light on or off.
If the joystick panel is switched off with the 1/0 button the light 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. The LED’s illuminate indicating which direction the
searchlight is travelling in. The pan movement is in a circular array of LEDs, when the LED’s start
to flash this indicates that the searchlight has reached the end of its travel in either left or right
direction. The tilt movement is illustrated with 11 vertical LED’s, the LED will also flash when the
searchlight has reached the end of its travel.
Home
The searchlight 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 searchlight to the home position switch the panel off then press the HOME button.
Set New Home Position
To set a new home position move the searchlight to the new desired home position. Switch the
panel off then press the joystick down to its limit and press the LIGHT button. The current position
will now be the new home position.

Set Motion Limit
The searchlight travel can be limited in either axis or either direction. To set a new limit, switch the
panel on and move the searchlight 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 the searchlight 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 LIGHT 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 1/0 button and keep the 1/0
button pressed. To increase intensity, move the joystick to the right. To decrease move to the left.
Note that the 1/0 button must be kept depressed whilst the joystick is moved. All indicators will
illuminate whilst adjustments are performed. Adjustment is complete when the 1/0 button is
released.
