Lamp Does Not Strike; Lamp Shuts Off - High End Systems Cyberlight User Manual

Lamp does not strike

Possible causes and solutions:
1. Cause: Bad lamp.
Solution: Replace with a new or known good lamp.
2. Cause: Improper voltage setting or power cord cap wiring.
Solutions: Do both of the following:
a. Make sure the fixture is set for the same voltage as the power supply. See
"Setting the Cyberlight® Fixture Voltage" on page 1-10.
b. Make sure the power cord cap is wired correctly. See "Obtaining and Installing
the Power Cord Cap" on page 1-9.
3. Cause: Power supply fuse F2 has failed. (Other symptoms are: the fans won't work
and control commands fail.)
Solution: Follow the instructions in the section titled "Replacing Power Supply
Fuses" on page 3-15 to inspect the fuse and replace it if necessary.

Lamp shuts off

Possible causes and solutions:
1. Cause: Over-temperature.
Note The fixture's maximum operating temperature is 50° C (122° F). An over-temperature
condition can be confirmed by a rapidly-flashing yellow Lamp LED. The location of rear-
panel LEDs is shown in Figure 1-1 on page 1-8.
Solutions: Do all three of the following:
a. Check for restricted air flow. Clean the fans, especially the fans in the lamp box
access door. The lamp box access door is shown in Figure 1-2 on page 1-11.
Instructions for cleaning the fans are shown in the section titled "Cleaning the
Fans" on page 3-3.
b. Verify fan power connectors are attached to the power supply board. See
"Setting the Cyberlight® Fixture Voltage" on page 1-10 for instructions on
removing the lamp box access door so you can check fan connections.
c. Check power supply board fuse F4. Follow the instructions in the section titled
"Replacing Power Supply Fuses" on page 3-15 to inspect the fuse and replace it
if necessary.
