Always isolate the equipment from the supply when fitting a lamp
See next sheets for fitting aid diagram
Before fitting the lamp:
-
Loosen and remove five M8 socket bolts with the dubo washer on the underneath of the
searchlight, then remove the upper hood off the searchlight & store along with the bolts and
washers in a safe area;
After fitting the lamp
,
-
Replace the upper hood, ensuring the groove aligns correctly with the glass gasket replace
the bolts and washers and make sure they are securely fastened.
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 the lampholder is in a good dry condition. Never allow water to collect in the lamp
fitting or come into contact with the lamp.
To fit the lamp:
-
Fit the rear lamp holder lead over the thread of the lamp and then screw into the rear lamp
holder;
-
Connect the front lead to the lamp and secure in place with the knurled nut;
Testing
Upon correct installation and connection to an electrical supply, the equipment can be tested in
order to ensure its’ correct performance. A competent person with some knowledge of electrical
equipment must carry out this work.
Equipment required:
Multi-meter with leads
Ammeter
Using the equation P=VI, the approximate power output of the equipment can be calculated in
the following way:
-
Using the multi-meter, take a voltage reading across terminals 4 & 5 inside the junction
box;
-
Using the ammeter, take an amp reading from the cable in terminal 4 inside the junction
box;
-
Multiply these figures together to give an approximate wattage (Power output).
For example:
Using a 300w xenon lamp:
Voltage reading = 20v; Amps reading = 15 amps
Therefore, Wattage = 20 x 15 = 300 watts
