Stewart Filmscreen Corp B - Manual (Page 17)

Modifying the extension of the screen
You can increase the extension of the screen up to 3" past the factory
preset stop, or you can decrease the extension by approximately 4-6" from
the factory preset stop. Do not attempt to modify the screen extension
beyond these recommended amounts.
The limit switches are located on the left side of the screen roller tube inside
the case, as shown in Figure 12.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the white extension (down) limit switch on the left side of
the screen tube. You access the white limit switch through the
small electrical grommet located on the case next to the end
plate. Use a small electrician’s style screwdriver or a 5/32” hex
wrench to turn the switch in a counterclockwise direction. If the
power is still on, the screen will drop incrementally as the switch
is turned.
Note: One complete turn of the switch will make approximately a
3/4" change in the screen's stop position.
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down.
Note: If your Luxus screen has a screen trigger, leave in the up
retracted position.
2. Locate the white extension (down) limit switch on the left side of
the screen tube. You access the white limit switch through the
small electrical grommet located on the case next to the end
plate. Use a small electrician’s style screwdriver or a 5/32” hex
wrench to turn the switch in a clockwise direction.
Note: One complete turn of the switch will make approximately a
3/4" change in the screen's stop position.
3. Activate the screen in the down direction until it reaches the
newly reduced stop position. Repeat this procedure until the
desired stop position is reached.
Once you have made the adjustment, whenever you lower the screen, it will
automatically stop at the new position.
Note: It is recommended that you make a note of any changes made to the
factory preset.
