Lamp Replacement
- Instruction Sheet -
If you have ruled out the cause being an aged lamp or another component in the projector, it
may indicate that your lamp has prematurely burned out or failed for some other reason (check
status LEDs and/or error codes through RS-232, if possible). Burned out lamps or lamps that
have failed due to some characteristic flaw should be replaced, as soon as possible.
In general, monitor the performance of your projector and replace lamps as needed.
About the Lamp Hot-Swap Feature
The projector is designed with the ability to remain operational during lamp replacement. You
can replace a single lamp without having to power down the projector. In this case, it is
strongly recommended that you switch to the single lamp mode for the lamp that you are not
replacing. For example, if you want to replace Lamp 1, switch to the Single, Lamp 2 mode of
operation. By switching modes, you cut power to the lamp that you want to replace, only after
the other lamp successfully turns on. It may take a minute for the lamp you just turned on to
reach full brightness, but your presentation will not be interrupted.
Once you have removed a lamp from the module, the lamp interlock remains “open”. As an
added safety feature, the projector will power down if you do not install another lamp (good or
bad) back into the module within two minutes from the time you removed the old lamp.
Can “live” lamps be replaced?
Live lamps (lamps that are still on) can be hot-swapped out of the projector. However, this is
not common practice and it is strongly recommended that you cut power to the lamp you are
about to replace, by switching Single Lamp modes, as described above.
If you still want to continue with replacing a “live” lamp it is important to remember that
when the lamp is removed the power supply for that side of the module is still active. Do not
stick your hands in the compartment!
NOTE: If you pull the only “live” lamp out in Single Lamp mode, the projector automatically
tries to turn the other lamp on. If this lamp was previously declared as a failed lamp, then the
projector automatically powers down.
To replace a lamp:
1.
TURN PROJECTOR OFF: If your presentation allows, it is recommended that you power
down the projector prior to replacing a lamp. Press
Power*
to power down the projector. The
projector fans will continue to operate for a short cool-down period. It is recommended
that you wait approximately 5 minutes to allow lamps to cool before replacing.
WARNING
It is strongly recommended that you allow the lamp to cool before replacing –
approximately 5 minutes.
