NOTE: Enter a serial number only if you have just installed a new lamp. This helps to ensure that the lamp timer
is not reset on an old lamp and that the number of hours logged on the lamp is accurate.
IMPORTANT !
Always record the serial number of a NEW lamp
.
Use the Cable Length (m) slidebar to define what lengths of high voltage DC cables are currently connected
between the lamp ballast and the "Anode" and "Cathode" ports on the rear of the projection head (refer back to
Figure 3-35 ). This regulates the voltage drop that occurs over distance, and ensures that adequate voltage
reaches the lamp. Particularly in projectors rented for temporary installations, this setting may have to be
changed from its last use. Adjustment range is 2-30m (6½-100 ft.).
IMPORTANT !
Always match this setting to your current cable lengths.
3.10.6 Adjusting Lamp Position (LampLOC™)
Use LampLOC ™ to align a newly installed lamp after its first power-up. For best results, select the Do Auto
control in the
LampLOC
menu and wait a few moments for the X-Y-Z values to stabilize. The motors and
sensors will work together to precisely position the lamp for optimized performance and brightness at the
screen, utilizing filtering to eliminate signs of lamp flicker. Progress status is displayed near the bottom of the
menu. When complete, the lamp alignment is optimized for the current installation.
NOTES: 1)
A 10-minute warm-up is recommended before adjusting LampLOC ™ .
2)
Intensity mode (brightness
tracking/LiteLOC
™
) is disabled during a LampLOC
™
adjustment.
NOTE
: Using "Max Brightness" or a maximum Lamp Power setting exceeds the maximum values shown here by
approximately 10%. Avoid prolonged use.
Using the LampLOC™ Slidebars
The individual LampLOC ™ slidebars, each of which moves the lamp along one axis only, are provided
incase the Do Auto button fails or if you feel a manual, operator-assisted lamp optimization produces more
output. Either measure your results with a light meter at the lens and screen, or simply watch the intensity
values near the top of the menu. Note, these slidebars you may attain a slightly higher peak than with the
Do
Auto button, but this peak may not be centered on the lamp curve thus lamp performance may not be
optimized. The Do Auto button also utilizes filtering to eliminate the effects of any lamp flicker. In general,
use the individual slidebars if you feel it is unavoidable.
