compromised.
ACTION
– Ensure that the ambient temperature for the Source is within
specification.
5.2 Other Troubleshooting Tips
5.2.1 Source does not flash
-
Verify whether or not the Source is fitted with a visible light filter. A
Source with a visible light filter does not display a flashing light.
-
Verify that the wiring is correct and that there are no stray wire strands
that could create an intermittent short.
-
Verify that the voltage at the Source wiring terminal is stable and meets
minimum requirements.
-
If all above conditions are met and the Source does not flash, replace
the lamp. Detailed instructions are in the lamp replacement kit listed in
the Spare Parts section.
