13. HDF Light Processor
13.5 Replacement of the shutter
Dowser assembly
The shutter of the projector is mounted upon the Light Processor just above the light output path of the prism. The shutter assembly
has an “open” and a “close” state. In the “close” state the shutter blade shuts off the light beam between the Light Processor (DMD’s)
and the lens. In the “open” state, the shutter is retracted from the light beam. Note that the local keypad has a dedicated button
“SHUTTER” to operate the shutter.
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.
