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

Section 1: Introduction
3.8.3 Adjusting Lamp Power (LiteLOC™ or Manually)
There are two different lamp modes for general operation-you can maintain either a specific brightness level
(LiteLOC™) or a specific lamp power level. NOTES: 1) Requires Advanced/Admin TPC rights. 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 (Figure 3-46):
1. In the TPC's 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 will gradually and automatically
supply 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).
4. To change your LiteLOC™ setting, adjust the Lamp Power as desired and then click Set. The LiteLOC™
function will automatically begin 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.
