• LAMP INFORMATION
Displays the Serial Code, Lamp Serial Number and the
maximum rated Lamp Power.
• LUMINANCE ADJUSTMENT
• Adjust (Luminance)
Luminance Adjustment allows you to calibrate the
Luminance vs. Lamp Power table stored in the
Projector.
Because Lamp Output vs. Lamp Power drops most rapidly
during initial hours of operation you may wish to perform
the Luminance Adjustment process more often, e.g., every
25 hours of lamp operation, during this period. Typically,
after the initial 100 hours of lamp operation the changes to
Lamp Output vs. Lamp Power is more gradual and
performing Luminance Adjustment every 50 to 100 hours
of lamp operation should be adequate.
Refresh SMS Server
In the REFRESH SMS Server group you can manually
force the SMS Server application to refresh the SMS
Server with Projector stored data.
Normally the SMS Server is the only device controlling
the Projector and tracks any changes made by the SMS
Server to the Projector as they are made. However, if
changes are made to Projector settings using the SRX
Controller application these changes are not under the
control of the SMS Server and are invisible to it. While
normal operation does not make use of the SRX Controller
application, maintenance operations may. Once any
changes are made to the Projector using the SRX
Controller, you should insure that you are seeing the most
current information on the Projectionist Terminal by
manually refreshing the SMS Server data and returning to
the PROJECTOR MAINTENANCE pane.
To refresh the Projector Data, tap Menu , tap
Maintenance , tap Projector , and then tap Refresh
Projector Data in the REFRESH SMS Server group.
Lamp Information
Every lamp is identified by a unique 16 digit Serial Code
that includes the manufacturer id, lamp power (min./max.
range), and the individual lamp serial number.
The Serial Number of the currently installed Lamp and the
Drive Elec. Power (max) is shown in LAMP
INFORMATION. A new Lamp Serial Code is entered
during the Lamp replacement process using the SRX
Controller application or the Installer screen (Role
restricted). The Lamp Hours and Timer ON Hours values
(see
“Lamp Status” on page 37 ) are automatically set to
“0” (zero) and the Replacement Date is set to allow
tracking of hours of usage following replacement.
Luminance Adjustment
Projector maintenance may require the re-calibration of
Luminance.
Adjust (Luminance)
The SRX-R320 Projector includes a Lamp Control Mode
feature which, when enabled using the SRX Control
application, maintains a nearly constant screen luminance
as the lamp ages and the bulb brightness vs. lamp power
applied is reduced. During the lamp replacement
procedure, lamp positioning is optimized. In addition, a
lamp brightness (luminance) vs. Lamp Power table is
created.
