Section 3: Operation
The Lamp Operation modes are:
•
Lamp 1 single lamp use
or
Lamp 2 single lamp use
modes will only use the lamp specified. If the selected
lamp will not strike, then the projector will not turn on. If the “Single Lamp Switch on fail” option is enabled,
the projector will always attempt to turn on the selected lamp first, but if that lamp fails all attempts to strike,
it will cause a switch to the other lamp. This option is not enabled for DLV models, which are restricted to
operate in Dual Lamp Use mode only.
•
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:
• 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)
• The lamp that has been least used (determined by the lamp voltage, which increases as the lamp ages)
• 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. This
option is not enabled for DLV models, which are restricted to operate in Dual Lamp Use mode only.
Single Lamp
mode, available for DLV models only.
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: 1)
On DLV projector models, the power control is fixed at
150W to maximize lamp life. In
Constant Power
mode, use the
Dynamic Iris Position
slider (
Dynamic Iris
Menu, see
Appendix A: Menu Tree
) to adjust brightness. Make sure that Dynamic Iris is set to Manual mode. In
Constant Intensity
mode, use the
Intensity
slidebar to adjust brightness.
2)
Constant Intensity
mode cannot
operate correctly if the LiteLoc calibration has not been performed.
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.
INTENSITY
Adjust the lamp intensity to the required % of full. This value is used as a target value by the LiteLOC
system to maintain constant intensity.
NOTE
:
When operating in Constant Intensity mode on DLV projector
models, the Intensity slidebar will adjust both the lamp intensity and the Dynamic Iris position to maintain the
required intensity.
