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
A single lamp can be replaced without having to power down the projector. In this
case, it is strongly recommended that you cut power to the lamp you want to replace
by switching to the single lamp mode for the lamp you are not replacing. For example,
if you want to replace Lamp 1, switch to Single Lamp 2 operation mode. When the
lamp is successfully turned on you can proceed with replacement. It may take a
minute for the lamp just turned on to reach full brightness, but your presentation will
not be interrupted.
NOTE: When a lamp is removed the safety interlock is “open”. As an added safety
feature, a lamp (functional or not) must be installed within two minutes of removing
an old lamp, otherwise the projector will automatically power down.
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.
