ADJUST THE SCREEN’S RETRACTED
(UP) STOPPING POSITION
We typically don’t advise users to make ad-
justments of this switch because they can
inadvertently damage the screen and or
motor if the fully retracted stopping posi-
tion is set “too high” into the housing This
will cause the screen’s batten bar to impact
the screen roll and may cause optical dam-
age 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 over run The “Up” limit switch is the “Yellow” adjuster in fig 1 It is
the # 2 adjuster on older screen motors
In the fully “up” retracted stopping position, the screen’s batten bar must hang freely underneath the
screen roller tube The batten bar can not 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
Counter-clockwise adjustments of this switch will “raise” the batten bar and clock-wise adjustments will
“lower” the batten’s top setting Lowering the batten’s top stopping position is valuable when trying to
align the screen’s batten with a finished ceiling slot
SUMMARY
Please remember that improperly adjusted limit switches will cause damage to your projection screen
or motor Make sure that both of the limit switches have been properly adjusted allowing the projection
screen to stop correctly at both the retracted and deployed positions
