R599791 - FORCE 3D User Manual 73
• Dual Lamp Use mode will use both lamps together. After 3 failed attempts to stay in Dual Lamp Use mode, the
projector will switch to Single Lamp operation; however, the user-selected mode remains as Dual Lamp Mode.
•Auto-Select a Single Lamp mode will choose the best lamp for single lamp operation. The lamp selection is
based on:
a) The lamp that will be the fastest to turn on (a lamp can be chosen if it is currently on, or if it has been off for at
least the minimum hot re-strike period)
b) The lamp that has been least used (determined by the lamp voltage, which increases as the lamp ages)
c) The lamp with the fewest hours (this attempts to balance the lifetime of the two lamps)
In Auto-Select Single Lamp mode, a failure of a lamp to strike will cause a switch to the other lamp.
Lamp Mode
Determines how the lamp’s power and intensity are controlled. If Maximum Brightness the lamp burns as brightly as
possible. Select Constant Intensity mode to maintain a specific brightness level over time. As the lamp ages, the
projector will increase power as needed, to closely maintain the required output from the lamp. Select Constant
Power to specify the power level supplied to the lamp. Both Constant Intensity and Constant Power modes extend
lamp life.
NOTES: Constant Intensity mode cannot operate correctly if the LiteLoc calibration has not been performed.
Lamp Power
Set the lamp’s power in Watts. The Power control represents the amount of power sent to the lamp(s). Power
increases when operating in Intensity mode, until it reaches its maximum. The value remains stable when in Max
Brightness or Power mode. If using Power mode, setting a lower power level reduces brightness and extends lamp
life.
Lamp Intensity
Adjust the lamp intensity to “%” of full. This value is used as a target value by the LiteLOC system to maintain
constant intensity.
Yellow Notch Filter
Refer to “Yellow Notch Filter (YNF)”, page 53.
Single Lamp Switch on Fail
Selecting this check box causes the projector to automatically attempt to start the other lamp if the current lamp
experiences problems, and is preventing a light on the wall. This applies if there is a failure to start a lamp, or a
failure during operation. This feature applies only to systems which have multiple lamps and are currently set to run
in a single lamp operating mode. A brief period with no light may occur before the other lamp becomes active.
Dynamic Iris
Refer to “Dynamic Iris”, page 59.
Warn when Lamp reaches (hours)
Enter the maximum number of hours (threshold) for lamp usage. When the threshold (set number of hours) is
reached on either lamp, a warning message displays on the status system, indicating that the lamp should be
changed. This setting is user-defined only, has no bearing on lamp warranty, and is not tied to actual lamp life in any
way. The default setting is 0, which means that the feature is off, and no warning will be generated.
Lamp 1 s/n and Lamp 2 s/n
Enter the serial number for the specified lamp. This will apply the serial number to the current lamp statistics file. It
will not perform the archiving as done by the CHANGE LAMP function.
Change Lamp - Submenu
Initiates the lamp change process for the selected lamp and allows the serial number of the new lamp to be entered.
Lamp serial numbers are used for keeping statistics on each lamp used in each lamp position. Entering of serial
numbers is optional, but is recommended.
When using this function, the statistics from the previous lamp are archived, and starts statistics tracking for the new
lamp. If this function is not used, statistics are accumulated (combined) for both the new and old lamps.
Lamp 1 History and Lamp 2 History
Lists the serial number and the number of hours logged for each lamp (current and previously) installed in the
projector. The current lamp appears at the bottom of the list. This entry is added automatically when you record a
new serial number during the lamp change process. See Change Lamp - Submenu.
