Adjusting Lamp Power (Liteloc™ Or Manually); Using Liteloc; Adjusting Lamp Position (Lamploc™) - Christie CP2000-ZX User Manual

3.6.2 Adjusting Lamp Power (LiteLOC™ or Manually)
There are two different lamp modes for general operation - maintain a specific brightness level (LiteLOC™) or
a specific lamp power level. NOTES: 1) Requires Advanced user permissions. 2) Keep in mind the formula:
Current (Amperes) x Voltage (Volts) = Lamp Power (Watts). 3) Adjust LiteLOC™ before or after
adjustment of lamp position.

Using LiteLOC™

Maintain a specific brightness level from your lamp over time as follows:
1. In the Advanced: Lamp menu, adjust Lamp Power until the desired light output is reached at the screen
(typically 14 fL). Any LiteLOC™ will automatically be disabled.
2. Click Set to record the current brightness reading in memory. NOTE: arbitrary units-of-measure are
shown above the light output bar.
3. Enable LiteLOC™. As the lamp
ages and loses efficiency, the
projector gradually and
automatically supplies more current
to the lamp as necessary to maintain
your chosen level of light output for
as long as possible (the light level is
read from an internal light sensor).
To change your LiteLOC™ setting,
adjust the Lamp Power as desired
and then click Set. The LiteLOC™
function automatically begins to
maintain this new setting.
When should I use LiteLOC™?
Typically, most theatre installations
would use LiteLOC™ for daily
operation, since it need only be set once for each lamp install and ensures consistent worry-free brightness at
the screen for as long as possible. If desired, reset LiteLOC™ to a different level at any time or override with a
specific lamp power setting.
How long can I maintain brightness?
Software can maintain a LiteLOC™ setting until the required power exceeds the maximum rating for the lamp
(2.0 or 3.0 kW) by approximately 10%. The lower your LiteLOC™ setting, the longer it takes to reach this
"over-drive" threshold and the longer you can maintain the desired brightness.
Adjusting Lamp Position (LampLOC™)
Align a newly-installed lamp as soon as possible to ensure optimized lamp performance and peak brightness at
the screen for the life of the lamp. NOTES: 1) Before adjusting, a 10-minute warm-up is recommended. Also
make sure to follow all the criteria specified in
either before or after adjustment of Lamp Power or LiteLOC™.
