METAL HALIDE MODE LAMP NOT IGNITING
Fixture must have 120VAC at the control input (u ground plug), not a
dimmed line and display at the rear of the hanger assembly must be lit.
Check that the lamp lock door is closed and door interlock switch is
operating.
Flip power switch on and off and listen for contactor assembly to click in
and out.
Check head extension cables and panel mount connector pins (paying
particular attention to the small pins are not dislodged or damaged which
would cause improper contact.
Install lamp ensure is properly seated (ceramic against ceramic and the
contact tee bolt clamp is tight).
Test with a ballast (ensure output matches lamp wattage) and a head
extension cable that are known to be good.
Ensure line voltage to ballast input is above 205 VAC when under load.
Check socket contacts and wiring to socket. Check for signs of overheating
contacts or arcing.
Wet ballasts will need to be placed in a warm dry location and allowed to dry
before attempting to use.
Hot restrike: it is important to note that if the power to the U ground plug
is interrupted the lamp will shut off, and will require a fifteen minute
cooling cycle. Power should be restated as soon as possible to allow the fans
to cool the fixture and lamp.
TUNGSTEN OR METAL HALIDE LAMP RUNS AND
SHUTS OFF AFTER TEN OF MORE MINUTES
Check lamp cooling fan (not the gel fan) for air flow and obstructions. The
air intake is located in the underbody of the yoke on the lamp left side.
The lamp fan should turn on and run for ten minutes when the control
system is first powered on and operate for ten minutes then shut off. The
fan will then restart when the lamp is started.
Check that the lamp lock door is properly closed.
Check that control system voltage at the fixture is 120 VAC, long cable runs
can significantly reduce voltage, thus decreasing fan performance.
