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 empty lamp 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.
Before you proceed with lamp replacement.
◊
Read, and make sure you understand the Lamp Replacement procedure before
you begin.
◊
Do not stick hands into an empty lamp compartment while the projector is
still plugged into an AC outlet.
◊
Use caution when handling lamps. Lamps, even those that have been through a
cool down period, are still hot due to the temperature emitted by the other
operational lamp.
◊
Do not touch the glass surface of the lamp. Handle the lamp by its handle
only. Intense heat can accumulate in areas where fingerprints exist. These
"hotspots" can lead to an accumulation of intense heat, which may result in the
lamp exploding. Wearing clean cotton gloves when handling the lamp will
prevent getting fingerprints on the glass surface.
