Lamp shuts off when shutter closed
After a Shutter Close command is issued, the lamp shuts off and goes into cool down mode.
Details
The following are potential root causes for the issue:
• The lamp extinguishes due to age. Lamp power is automatically reduced when the shutter is
closed. Older lamps have difficulty maintaining the arc when the power is too low.
• The projector may be operating out of specification for tilt angle, which can accelerate the aging
process of the lamp.
• The projector line drawings were not available on the Christie website; therefore, the installers
may not have been aware of the angle limitations of the projector.

Solution
1. To check for an old lamp, reduce lamp power to minimum without closing the shutter and check
if the lamp automatically extinguish on their own within five minutes. Replace the lamp with a
new one and check if the problem persists.
2. Ensure the projector tilt is no more than 15 degrees as specified in the lines drawings available
on the Christie website:
