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.
3 - Technical Information This product has been designed to operate in accordance with the product specification. The L230RC searchlight has the following features: All marine grade materials and fixings; Parabolic formed aluminium reflector; Powder coated finish & stove enamel paint finish;...
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.
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.

Installation Guidelines A typical installation and connection routine for the L230RC Low Voltage searchlight is as follows: Referring to wiring diagram C27423, a supply is fed to the junction box, which then provides a common feed to the motor gearbox, searchlight and 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. The searchlight can be remotely positioned via the joystick control panel, with the facility for movement up, down, left and right.

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; Eye protection must be worn when handling lamps that have been removed from their packaging materials.

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;...

FBUS ADDRESS SWITCHES OVERVIEW FBUS uses two types of address switch. One type is rotary, and the value selected is the value shown on the dial. The other type is rows of switches whose operation is described below: - The switches all operate in the same manner producing a binary value with the highest binary value to the left and the lowest value to the right.
Page 16
EXAMPLES Standard control panel – panel address set to 5 Switch 1 = Off Switch 2 = On (Value 4 added to address) Switch 3 = Off Switch 4 = On (Value 1 added to address) 4 + 1 = 5 Speed control card - lamp address set to 11 Switch 4 = Off Switch 5 = On (Value 8 added to address)

FBUS DATA PROTOCOL OVERVIEW The Francis bus (FBUS) is a custom communication protocol based on RS485 two wire bi directional communication hardware. The system provides a simple bi-directional link between lamps and lamp control panels. The system allows given panels to communicate with different lamps and also allows a number of panels to communicate with the same lamp.
Page 18
PANEL TRANSMITTED DATA Panels only send data when there is data to be sent i.e. there has been activity at the panel which must be sent to a given lamp. If there is no data to be sent, a panel will not transmit. The amount of data a panel sends will depend upon the amount of activity at the panel and can be 2 to 10 bytes.
Page 19
DATA_FOCUS_BUTTON (Hex 0B) This is a single byte command. When the lamp receives this, it will run the focus motor as long as the command remains. A panel will send this command so long as the focus button is pressed. DATA_HOME_BUTTON (Hex 0C) This is s single byte command.
Page 20
DATA_TILT_POSITION (Hex 19) This is a three-byte command. Following the DATA_TILT_POSITION command two data bytes specify the position to which the lamp must move. The bearing resolution is 0.1 degrees. The value is sent LSB first with the first byte representing the lower position command bits. The MSB (sent last) lower 4 bits represents the remaining value.
Page 21
The CRC is a simple data checking system. Basically, this is just the sum of the lamps address and bytes above. The value is radix to 8 bits. If the lamp address was 0 (bus address value 16) and the pan and tilt were both at centre and the lamp was switched on and all other status bits were 0 the values would be Hex 110, 80, 80, 01.
Page 22
4. Send pan value half speed = 128 + (64/2) = Hex A0 within 1mS. 5. Send CRC value, in this case Hex 116 + Hex 01 + Hex A0 = 1D7 after radix to 8 bits = B7. 6. This completes the transmission RECEIVING FROM A LAMP Lamps broadcast data sequentially.

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.

FBUS INTERFACE UNIT (if supplied) OVERVIEW Francis Searchlights FBUS system is designed to allow multiple control panels to manage a number of searchlights on a common data cable. The data system is application specific and, as such, has a fixed data rate and complex timing.
Page 25
SET PANEL ADDRESS The FBUS interface looks like a standard control panel to the FBUS as such it must have a panel address. The panel address must not be set to the same value as any other panel on the system. Panel addresses start at 0 and go up to 15.

LAMP SOFTWARE This displays the software version of the currently selected lamp LAMP TYPE No This displays the lamp type number. EXT COMMS DATA This item is included to aid external interface development.
Page 27
DATA_STORE_HOME (0x 0F) This is a four-byte command (Sync, Lamp address, command, CRC). A lamp receiving this will store the current pan and tilt position values and will move to these values when the DATA_MOVE_TO_HOME command is issued. DATA_PAN_CLOCKWISE (0x14) This is a five-byte command (Sync, Lamp address, command, speed, CRC) The speed value is between 0 and 127.

increment as the lamp moves from centre. The least significant byte comprises the lower 7 bits of the value with the most significant bit set to zero. As an example, a value of 0x0A followed by 0x08 would indicate an angle 1 degree up of centre.

10. Fault Status 2 Bit 0 - Limit switch error. Bit 1 - Datum error. Bit 2 - Lamp type invalid. Bit 3 - Supply voltage out of tolerance. 11. Lamp software version. 12. Lamp type No. 13. CRC ERROR CONTROL Error control is supported by a CRC following each data packet.
7- Fault Finding All fault finding must be conducted by a competent person or qualified Electrical Engineer. Failure of Lamp to light Causes: 1) Power not supplied; 2) Fuse blown; 3) Failed lamp Remedy: 1) Check voltage at supply. If supply is not present the fault is at the customer supply. If power is present, see remedy 2;...
8 - Maintenance and Servicing In order to prolong the service life and performance of your searchlight, the following maintenance guidelines are recommended: Maintenance checks should be conducted before every voyage or at least every three months; Before checking, disconnect the equipment from the supply; ...
