ADJUSTING THE SCREEN MOTOR LIMIT SWITCHES
We typically don’t advise users to make adjustments of this switch because they can inadvertently dam-
age the screen and or 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 over run The “Up” limit
switch is the “Yellow” adjuster in fig 1
Down unit adjustment
UP unit adjustment
Fig 1
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
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
Contact the factory if you have any questions or concerns regarding the use of your projection screen limit
