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 LED fitted be applied to the LED 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;
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 110/220v 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 - 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
