LIMIT SWITCH ADJUSTMENT (CONTINUED)
ADJUST THE SCREEN’S RETRACTED (UP) STOPPING POSITION
CAUTION: Making adjustments to the yellow switch can inadvertently damage the screen or the
motor if the fully retracted stopping position is set too high into the housing. This will cause the
screen’s batten bar to impact the screen roll and
may cause optical damage to the screen. Improper
adjustment can also cause the batten to jam into the
housing which obstructs it from deploying when the
“down” command is sent. Left in this position, the
motor will fail due to overrun. Only qualified,
experienced technicians should attempt to make
adjustments to the “up” yellow limit switch (see
Figure 16).
NOTE: Failure to follow these directions may
result in voiding your warranty.
In the fully “up” retracted stopping position, the
screen’s batten bar must hang freely underneath the screen roller tube.
The batten bar cannot
contact or press against the projection screen roll. Make sure to check and correctly adjust
the yellow or “up” limit switch to avoid screen damage from a compacted batten bar.
Switches are sensitive. Go slowly and do quarter turns at all times with the 5/32” hex driver to
prevent damage to the motor and to the screen.
Counterclockwise adjustments of this switch will raise the batten bar and clockwise adjustments will
lower
the batten’s top setting. Lowering the batten’s top stopping position is valuable when trying to
align the s
creen’s batten with the bottom of the Visionary case.

CAUTION
Please remember that improperly adjusted motor limit switches will cause damage to
your projection screen or motor. Make sure that both of the motor limit switches have
been properly adjusted, allowing the projection screen to stop correctly at both the
retracted and deployed positions.
