8.13 Replacement of t he dowser (shutter)
Dowser assembly
The dowser or shutter (“dowser” is mor e common in the cinema market and “shutter” in the events market) of the projector is m ounted
upon the Light Processor just above the light o utput path of the prism. The dowser as sem bly has an “open” and a “close” s tate. 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 k eypad has a dedicated button “DOWSE R” to operate the dowser.
The Light Processor has to be removed from the projector before replacing the dowser. This procedur
eas-
sumes that the Light Processor is already remo ved from the projector.
Necessary tools
2,5 mm Allen wrench.
