Maximizing Light Output
Upon powering up the projector with a newly-installed/replaced
lamp, adjust lamp position to help ensure optimized operation as
well as peak brightness at the screen—you do not need an image
displayed yet. Once you have done this LampLOC
adjustment,
the lamp will be well centered and distanced correctly from the
remainder of the illumination system.
At the TPC, automatically optimize lamp position by pressing the
DO AUTO
button in the
Advanced: Lamp
menu. Watch the
gauge on this menu. After 2-3 minutes, with the projector using an
internal light sensor, the best lamp position will be established and
the
DO AUTO
button will no longer be disabled. At this point,
light output is optimized.
NOTE
:
Lamp must be on and the shutter open during LampLOC
adjustment,
however the projector does not need to be displaying an image.
2.9.1 Determining Screen Brightness (fL)
In order for the TPC to display screen brightness in footlamberts (fL), you must measure screen brightness at
both extremes of lamp power (minimum and maximum) for a given lamp type, and record these two readings
in the TPC
Admin: Lamp
menu available to installers. These measurements establish a range (stored in
memory) from which the TPC can interpolate all other lamp power settings, converting them to approximate
footlamberts for display in the menus. Repeat the calibration if you ever switch to a different lamp type/size.
For more information about menus and footlamberts, refer to
Section 3 Basic Operation
.
2.10 Basic Image Alignment
NOTE:
Assumes projector is fully assembled and powered up in its final location.
This procedure ensures that the image reflected from the DMDs is parallel to and well-centered with both the
lens and screen. This initial optical alignment is the foundation for optimizing images on the screen, and must
be completed before final boresight adjustments. To save the focus, offset and zoom settings to the channel,
you must make the adjustments using the motorized lens mount adjustment features in the
Main: Lens
menu
or
Custom: Lens
menu from the TPC. Using the Emergency Override knobs on the lens mount to adjust these
positions does not save the settings to the channel. They are designed for temporary/emergency use therefore
hone reference settings will be lost once the channel changes. If used, click
Lens Reset
from the
Advanced:
Lens
menu to ensure ILS settings are properly recalled. Ensure the
CP2000-XB is properly positioned relative
to the screen before you begin.
