1) A failed safety interlock automatically prevents power from going to the lamp and disables the lamp button on the
TPC Main menu. Since most interlock alarm conditions are triggered by switches, regularly check the operation of these
switch levers. 2) With interlock integrity restored, the lamp button on the TPC Main menu is automatically re-enabled.
How to Correct
Make sure the lamp door is securely shut.
Check for interference at vane switch. Make sure the
220V line cord near Panel C (rear, underside) is still
plugged in. Replace fan.
May not be turned on. 600 cfm required.
Replacement heat extractor may be required.
Check auxiliary switch wiring in pedestal. Check the
external controlling device.
Lock the projector lid. If still failed, double-check the
high-security lock itself, plus all related harnessing.
Make sure a "Type 3" Interface Board is installed
and that you are using main s/w v10.0.30 or higher.
Power down & cool projector. Ambient temperature
may be too high. Check air filter and fan.
Power down & cool projector. Reduce lamp power.
Ambient temperature may be too high. Check air
filter and sensor. Check liquid cooler fan.
Power down & cool projector. Reduce lamp power.
Ambient temperature may be too high. Check air
filter and sensor. Check liquid cooler fan.
Power down & cool projector. Reduce lamp power.
Ambient temperature may be too high. Check fluid
flow and level. Check air filter. Check liquid cooler
fan.
Power down & cool projector. Reduce lamp power.
Ambient temperature may be too high. Check fluid
flow and level. Check air filter. Check liquid cooler
fan.
Power down & cool projector. Reduce lamp power.
Ambient temperature may be too high. Check fluid
flow and level. Check air filter.
Cool, then cycle the projector down-and-up
normally. If the over-temp recurs, there is a cooling
problem in the ballast that may require service.
Check ballast fan.
Replacement fan may be required.
Replacement fan may be required.
Replacement LAD filter or fan may be required
Replacement of the lamp is recommended
Increase Lamp Power. Check that DMDs have not
overheated. An interlock may have momentarily
tripped. Lamp may have to be replaced.
If interlocks are OK, make sure the 220V line cord
near Panel C (rear, underside) is still plugged in. If
lamp re-try still fails, replace the lamp.
Check cabling. Cycle projector power for a normal
start-up. Check LEDs on card cage boards, which
can indicate a light engine problem instead. Check
LVPS/Processor voltages. Also, if shutter or lamp
are functioning normally, SSM likely OK.
There may be a power problem with the main
electronics (I 2 C). Check LVPS/Proc. voltage.
