Advanced: Lamp History Menu Functions - Christie CP2000 User Manual

BASIC OPERATION
3-26
ADVANCED / LAMP MENU:
controls for optimizing lamp alignment (LampLOC), maintaining a specific light
output over time (LiteLOC), or setting a precise power level for the lamp. Two read-
only areas display related lamp performance details—the side bar graph represents
the current light output and, if LiteLOC is enabled, a heavy line shows the chosen
LiteLOC setting. In addition, the "New Lamp" button activates a window for
entering the serial number of a newly installed lamp. This button is also available
with an "Operator" login (with the rest of the Lamp menu disabled—refer back to
Figure 3.4).
LiteLOC Maintains a chosen light level at the screen over time—the lamp ballast
will gradually increase power to the lamp as necessary, until it reaches
the maximum level possible for the installed lamp. To disable LiteLOC
temporarily or permanently, clear the LiteLOC "Enable" checkbox or
adjust Lamp Power directly.
Set (Brightness) With the desired light output measured at the screen (typically 14 Fl),
press the Set Brightness button to automatically enable LiteLOC. The
current brightness level will be maintained as long as possible. NOTE:
Arbitrary units-of-measure appear here, not footlamberts or lumens.
Lamp Power Indicates what percentage of power (appropriate for the installed lamp)
to supply to the lamp, automatically overriding any LiteLOC setting that
may be in effect. This causes the bar graph to rise or fall, but the
LiteLOC line and "Set" values will not change unless "Set" is pressed
(defining a new LiteLOC setting). Lamp Power range = 75%-110%,
representing the percentage of the lamp's power rating. Factory default
= 75% power.
LampLOC LampLOC buttons activate motors that reposition the bulb in the
projector for optimized light output. Use the Do Auto button
(recommended) or the individual buttons. Notes: 1) Lamp must be ON
to begin. If it is turned off during a re-positioning, the bulb will return to
its former position. 2) Douser opens and remains non-functional during
a LampLOC adjustment.
Lamp (read-only) Indicates the current lamp age, amps (current), volts (voltage) and
watts (lamp power). Read-only "FYI".
New Lamp Activates the lamp history window and text editing box for recording a
new lamp's serial number, which resets the lamp timer.
Light Level Indicates current light output (shown as solid vertical bar) and LiteLOC
(Meter Reading) level set (single horizontal line). Consider the value at the top of the
meter as arbitrary—i.e., not representing actual lumens or fL.
ADVANCED / LAMP HISTORY MENU:
appears here, along with their dates of entry and number of hours logged. This is a
read-only menu unless activated via the "New Lamp" button on the Lamp menu,
which adds edit boxes and a Save button for recording in memory the serial number
of a new lamp and the number of hours it has already been in use (if applicable).
