Wolf Cinema Owner's Manual 3-50
For example, a 1000 watt lamp can be driven at no more than 1000 watts. To produce desired
brightness at the screen, a new lamp would likely need less than this maximum rating — perhaps
812 watts (example only). Over time, however, the lamp will require more and more current in order
to generate the desired light, until eventually the lamp wattage reaches its 1000-watt maximum
and the lamp power automatically levels off. at this point, the tracking function terminates (i.e.,
the power level stabilizes) and the lamp will begin to dim normally. either reduce your “Intensity”
setting or replace the lamp.
Do not lower the “Intensity” so much that the corresponding “Power” value reaches its minimum
— the intensity setting will be inaccurate and cannot be maintained. For best results in achieving
uniform intensity amongst tiled images, choose an “Intensity” setting that enables all lamps to
operate at less than the maximum number of watts available in your projector but high enough to
keep the corresponding lamp power above its minimum. See “Power”, above.
nOTes: 1)
Lamps become more stable over time, thus a specific intensity is more easily
maintained as the lamp ages. 2) Intensity can be set only if the lamp is in “Intensity” mode 3)
Intensity cannot exceed the output of Max Brightness mode.
IRIs – The iriS inside the projector controls the diameter of the
light beam passing through the system. With a fully open aperture
(slidebar default of “0”), the maximum amount of light passes
through for maximum brightness in your images. increase the
slidebar setting to reduce the aperture diameter and maximize
contrast ratio instead.
laMP HIsTORY – This read-only option lists the lamps most recently installed
and recorded in the projector. lamp History automatically updates whenever
you record a new lamp serial number — the new lamp is added to the bottom
of the list.
Use CHanGe laMP to record the serial number for a newly installed lamp:
in the Lamp S/N window, use the number text entry keys to record the new lamp serial number
and press again to accept the change. See Using Slidebars and Other Controls if you need help
entering the number. Once entered, the new lamp serial number will be
added to the Lamp
History menu and the Lamp Hours timer will reset to “0”. Lamp Mode and Lamp Limit remain as
they were for the previous lamp and can be changed at any time. See Figure 3.12.
