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. The protective sleeve
should not be removed from the lamp
for safety reasons as there is a
remote possibility of the lamp
shattering violently, especially if it is
submitted to mechanical shock or
vibration.
Quartz lamps should not become
contaminated with oils, grease or
come into contact with skin.
When fitting the lamp:
Always isolate the equipment from
the supply before inserting a lamp;
Ensure the circuit is suitably
fused;
Ensure that the lamp is of the
recommended type and rating;
Check the lampholder is in good
condition. If the contacts show any
sign of corrosion the lampholder
should be replaced;
Check that 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:
Loosen all the thumbscrews on
the front of the searchlight,
allowing the bezel and glass to
hang clear on the captive bolt;
For easier access the light shield
may be removed by firstly undoing
the centre screw;
Cut open one end of the protective
sleeve surrounding the lamp;
Using the sleeve to prevent the
fingers coming into contact with
the lamp, position the two lamp
pins above the holes in the
lampholder;
Gently push the lamp into the
lampholder and discard the
protective sleeve;
Replace the light shield, fixing the
centre screw in position;
Position the front bezel onto the
searchlight and tighten the
thumbscrews until hand tight.
Testing
Upon correct installation and
connection to an electrical supply, the
equipment can be tested in order to
ensure it's correct
performance. This
work must be carried out by a
competent person with some
knowledge of electrical equipment.
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:
