    3 - Technical Information This product has been designed to operate in accordance with the product specification. The L560RC searchlight has the following features:  All marine grade materials and fixings;  Parabolic formed aluminium reflector;  Powder coated & Stove enamel paint finish; ...
  • Page 6: Unpacking And Installation Instructions

    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.
  • Page 7: Electrical 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.
  • Page 8 Installation Guidelines A typical installation and connection routine for the L560RC searchlight is as follows: Referring to wiring diagram C27425 a supply is fed to the junction 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 junction box provided.
  • Page 9: Operating Instructions

    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.
  • Page 10 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;...

  • Page 14 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 15 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)
  • Page 16 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 17 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 18 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 19 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 20 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 21 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.
  • Page 22 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.
  • Page 23 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 24 currently selected lamp is responding the bottom line of the display will show the current pan and tilt angles. 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.
  • Page 25 FOCUS This function is not implemented on all searchlights. Focus displays the current focus position with a value of 0-100. A value of 50 should represent the most focused beam with the beam diverging above and below 50. Note that the value will ascend from 0-100 the reset back to 0. Pressing the arrow up button will operate the focus motor.
  • Page 26 DATA_MOVE_TO_HOME (0x0C) This is a four-byte command (Sync, Lamp address, command, CRC). A lamp receiving this will automatically move to the pre-set home position. The command does not need to be maintained while the lamp moves to home. If a home position has not been defined the home position will be straight ahead with the lamp horizontal.
  • Page 27 DATA_MOVE_TO_TILT_POSITION (0x19) This is a six-byte command (Sync, Lamp address, command, position LSB, Position MSB, CRC). The position value is 12 bits and gives a resolution of 0.1 degrees. The most significant byte (sent last) comprises the top 5 bits. The most significant bit (bit 4 –...
  • Page 28 8. Focus position - Value between 0 and 100 - finest focus at value 50. 9. Fault Status 1 Bit 0 - Pan motor current high. Bit 1 - Tilt motor current high. Bit 2 - Focus motor current high. Bit 3 - FBUS +24V out current high.
  • Page 29: Fault Finding

    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;...
