Caution Do not allow anything to be placed upon the power supply case; the perforated top is for ventilation and must not be obstructed. Try to select a location as close to the lamphouse as practical. Many users install the power supply adjacent to the searchlight where space is available and local codes permit.

Warning The power supplies have two sources of power. Disconnect (turn off) primary power before making adjustments or service procedures. Output power adjustment Warning The power supply stores energy after primary power is switched off. Wait a minimum of two minutes for the capacitor charge to bleed off. Taps are provided on TB1 to alter the output of the power supply.

Xenon lamp power supplies have two stages of operation: Before igniting the bulb – At this time, the voltage at the power supply output terminals reaches “open circuit” value (110 VDC or greater). After igniting the bulb – At this time, the voltage at the power supply output is determined by the load placed on the power supply by the xenon lamp (18-30 VDC).

the capacitor is functioning. Reconnect it. High ripple current caused by a diode failure will result in overheating of R3. You may use a clamp-on A.C. ammeter on the common D.C. line to the capacitor bank as an indirect method of checking ripple. The 8502 capacitor bank will have a nominal 25 ampere (AC) current flow.
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 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 lamp fitted be applied to the lampholder contacts.

Installation Guidelines A typical installation and connection routine for the searchlights is as follows: Referring to wiring diagram C23114, a supply is fed to the PSU, which then provides a common feed to all other functions and equipment. Cables required to be connected by the customer: - 4 cores 6mm cable from the S/L into the PSU, doubling up the pairs, 3 cores 1.5mm cable from the S/L into the PSU, 3 cores 1.5mm cable to the Heater in the Searchlight,...

Fitting instructions for the 2Kw xenon lamp Referring to the diagram overleaf: Unfasten the eight Latches (A) on the front and rear of the searchlight; Remove the front bezel (B) and rear bezel (C) assemblies; Unscrew the two M6 hexagon screws (D) from the front lampholder mounting block (E) and remove the front lampholder assembly from the mounting bracket;...
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 PSU should be housed below deck/in doors. Never leave the PSU exposed to weather conditions.

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.

Notes: 1) XBO lamps are designed for dc operation only. The dc current may only be varied within the limits of the current control range. An XBO lamp operates best at rated current; over the life of the lamp, the current may be increased to its maximum value to compensate for loss of light.
7- Fault Finding All fault finding must be conducted by a competent person or qualified Electrical Engineer. Please refer to the following table for the trouble-shooting of Xenon lamps. Fault Cause Remedy Wrong Polarity Lamp incorrectly fitted Anode (large electrode) ...

Failure of Lamp to Ignite In the event of the xenon lamp failing to light the following steps should be taken: 1) Check that the mains supply is connected to the input of the PSU. On operating the switch, if the lamp does not light switch off mains supply and check all fuses; 2) On pressing remote starting switch the lamp still does not ignite, check the searchlight head.
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; ...
Switch (Weatherproof PSU enclosure) In order to prolong the life and performance of your product, we recommend that you only specify Francis Searchlights spare parts. This will ensure that any warranties on your equipment will not be invalidated. When ordering spare parts please contact the Sales Department at Francis Searchlights Limited.
