8.13 Replacement of the dowser (shutter)
Dowser assembly
The dowser or shutter (“dowser” is more common in the cinema market and “shutter” in the events market) of the projector is mounted
upon the Light Processor just above the light output path of the prism. The dowser assembly has an “open” and a “close” state. In
the “close” state the dowser blade shuts off the light beam between the Light Processor (DMD’s) and lens. In the “open” state, the
dowser is retracted from the light beam. Note that the local keypad has a dedicated button “DOWSER” to operate the dowser.
The Light Processor has to be removed from the projector before replacing the dowser. This procedure as-
sumes that the Light Processor is already removed from the projector.
Necessary tools
2,5 mm Allen wrench.
