:
Never open an interlocking adapter of a stacked projector which is still suspended. First place
the stacked projectors on the fl oor.
4.2 Aligning stacked FLM projectors
Necessary tools
8 mm Allen key.
How to align two stacked FLM projectors ?
1. Make sure that the internal hatch pattern projected by the reference projector is sharp and has a perfect rectangle outline. If this
is not the case, readjust the reference projector before aligning the other stacked projector(s) with the reference hatch pattern.
Note: The reference projector in a stacked con fi guration is the lowest projector in case of table mount and the uppermost
projector in case of ceiling mount.
2. Project with the stacked projector the same internal hatch pattern as the reference projector.
Tip: Use a white colored hatch pattern for the reference projector and e.g. green colored for the stacked projector. This
makes it easier to see the difference between both hatch patterns projected.
3. If necessary, adjust the rotation of the stacked projector with respect to the reference projector by turning in or out the height
adjustment ring of the interlocking adaptors at the rear of the stacked projector. Adjust until the outline of the hatch pattern is
most symmetric with the reference hatch pattern.
Tip: You can increase leverage by using a screw driver in the holes of the adjustment ring

4. If necessary, adjust the inclination of the stacked projector with respect to the reference projector by turning the height adjustment
ring of the interlocking adaptor at the front of the stacked projector in or out. Adjust until the outline of the hatch pattern is most
symmetric with the reference hatch pattern.

5. If necessary, adjust the skew of the stacked projector with respect to the reference projector by turning the screw Q in or out
using a 8 mm Allen key. The screw Q is located behind the cover of the lamp, just above the volt meter. Adjust until the outline
of the hatch pattern is most symmetric with the reference hatch pattern.
Note: See procedure "Removal of the lamp cover", page 181, to access the skew adjustment screw Q.
