DIGITAL DISPLAY
UPON ENERGIZING the LAMP circuit, the backlighting will illuminate the LCD screen.
The display
CHECK TOP COVER
will appear if the top cover if not secured. When the lamphouse access
cover is closed and correctly secured, and the blowers are operating, the display will appear as shown:
000V 000A 0000W
1234BLB 12345HR *
FOR PURPOSES OF ILLUSTRATION, the above display indicates a non-operating bulb
with 1,234 hours of use installed into a spotlight with 12,345 hours of operation. The asterisk (*) at the end
of the second line, when flashing, indicates that the display is active and awaiting input. Upon bulb ignition,
the upper line will display the arc voltage (V), the DC current (A), and the operating wattage (W) of the bulb.
The “wattage” readout on the digital display is an approximate figure and should not dictate the DC output
setting.
The figures will shift for the first few moments of bulb operation, but will stabilize after the bulb
reaches normal operating temperature and pressure. A plus sign (+) will replace the asterisk.
CLOSURE OF THE
LAMP
SWITCH will energize the contactor of the xenon power supply.
The high open circuit (“no load”) DC voltage will be displayed. When the open circuit voltage reaches 140
V.DC, the igniter will generate a RF pulse to bridge the gap between the bulb electrodes. This pulse, coupled
with the high open circuit DC voltage, will ignite the bulb. The voltage reading (V) will then fall to the bulb’s
sustaining level, and the DC amperes (A) and wattage (W) will be displayed continuously until the bulb is
extinguished.
ELAPSED HOURS will begin counting upon bulb ignition. Bulb hours (BLB) are limited to
four digits, and must be re-set when the xenon bulb is replaced. To re-set bulb hours, press the RESET button
accessible through marked hole below the LCD screen. The 5/64” allen wrench supplied with the accessory
kit is the correct diameter to clear the hole.
NOTE: WHEN RECORDING start-up and removal hours on the Xenon Bulb Record, use
the
total elapsed hours
(HR) figures. The (BLB) figure, re-set upon installation of the bulb, is a convenience
feature ONLY. Basing records of the lamp system on the total hours (HR) figures permits an accurate and
ongoing history of bulb usage.
IF THE XENON BULB fails to ignite, the following diagnostic messages will display on the
lower line of the LCD screen:
CHECK PWR SUPPLY
: If no DC current is sensed, and voltage does not exceed 125 V.DC, check the xenon
power supply. Repair or replace as required.
CHECK IGNITER
:
If the DC open circuit voltage reaches and exceeds 140 V.DC and the igniter fails
to pulse, replace the igniter.
CHECK XENON BULB
: Check the DC cables connected to the bulb. If the high voltage is shorting to
ground, and not arcing between the bulb electrodes, locate and correct (insulate)
the short circuit. If the high voltage arc appears between the bulb electrodes, and
the bulb fails to ignite, replace the bulb.
