MAINTENANCE RECORD
SOLUTION
Allow lamp to cool 10–15 minutes
before restarting.
Check that lamp is tight in socket.
Check connections inside connection
boxes on light fixtures and tower.
Check for:
broken arc tube or outer lamp jacket
broken or loose components in lamp envelope
blackening or deposits inside lamp tube.
Turn off circuit breaker.
Have a licensed electrician repair or replace the circuit
breaker.
Check incoming voltage to ballast. If voltage is incorrect,
engine speed may need to be adjusted or generator may
require service.
With the fixture cord removed from its receptacle, the
voltage should measure 400 to 445 VAC. If proper voltage
is not achieved, perform capacitor check to determine if
capacitor or coil needs to be replaced.
Replace lamp due to normal lamp life.
Check ballast for proper voltage output.
Clean reflective surface inside fixture
and both inside and outside surface of glass lens.

Fix the steel wire rope into the suitable position
