mode will not automatically switch to the single lamp mode. It is strongly
recommended if after 5 minutes the second lamp does not ignite, you manually
switch to a single lamp operation mode and replace the lamp that won't strike.
•
In single lamp mode, the projector will try to strike the lamp again in 90
seconds (considered re-strike #1). Only after the third attempt (re-strike #2)
will the projector declare the lamp as "Failed to Strike" (in Lamp submenu)
and automatically switch to the single lamp operation mode for the lamp that
was not ignited. All lamp specific menu options will then change to reflect the
true lamp operation mode of the projector.
NOTE: P-VIP lamps, by nature, do not successfully ignite when "hot" and
therefore the 90 second wait period is taken by the projector before each strike
attempt and between powering the projector down and up again.
Lamp operation modes will also automatically change if there is a failure of one of the
lamp related components, such as the lamp driver, color wheel or fan. An error code
or failure message will be displayed in the status LED or through the RS-232 serial
communications log that indicates which component has failed. The lamp status will
also show one of several messages that points to the failed component. The lamp in
this instance is typically still okay and does not require replacement.
MANUALLY SWITCHING FROM DUAL TO SINGLE LAMP MODE
to single lamp operation mode occurs immediately. The result is an instant dimming
of the displayed image. At this time, you can modify the lamp power or adjust other
settings to increase desired brightness.
MANUALLY SWITCHING FROM SINGLE TO DUAL LAMP MODE
switch from a single lamp mode to the dual lamp mode, the projector immediately
tries to ignite the second lamp. If the first attempt to ignite the lamp fails it will wait
90 seconds and try again. This process will continue indefinitely. It is recommended
you switch the lamp operation mode back to single lamp mode if the second lamp
does not ignite after 5 minutes.
MANUALLY SWITCHING BETWEEN SINGLE LAMP MODES
between single lamp modes, there is a 35 second overlap when both lamps are on.
This overlap allows the "new" lamp to warm up before the other lamp is turned off.
The new lamp operation mode displays immediately in the menus. Only after the third
attempt (re-strike #2), will an error message display to indicate the type of error that
was detected. If no specific error is detected, then the error will be "Failed to Strike".
If this occurs, the first lamp will not turn off and the projector will continue to operate
in the original lamp operation mode. In summary, it could potentially take the
projector up to 4.5 minutes to successfully switch lamp modes. The projector will
attempt to maintain light on the wall during this time. NOTE: If a problem is fixed
before the last strike attempt the lamp could turn on.
If a lamp fails during operation, the projector will immediately attempt igniting the
other lamp if it's not already on. Only in this case, will there be a brief interruption in
the display.
NOTE: A lamp will naturally decrease in brightness as it ages. Lamp life can also be
decreased further by a frequent change in lamp operation modes (number of times its
ignited).
