Screen Adjustment For Screens Without A Built-In Low Voltage Control
Screen travel is stopped automatically in the down and up positions by the limit switches that are preset at the factory.
No further adjustment is necessary.
If you need to make minor stop position adjustments see the appropriate step below.
SETTING THE DOWN LIMIT POSITION
NOTE: One turn of the limit screw equals approximately 2" of
screen travel.
To Reduce Screen Drop: Turn the down limit switch screw clockwise
to decrease the amount of screen drop. Run the screen down to test
the stop position. If the screen drops too far, raise the screen about
one foot and adjust the limit switch again. Repeat until the
desired position is set.
To Increase Screen Drop: Turn the down limit switch screw
counterclockwise to increase the amount of screen drop. Run the
screen down to test the stop position. If the screen does not drop
enough, raise the screen about one foot and adjust the limit switch
again. Repeat until the desired position is set. Do not adjust for more
drop than what was ordered. At least 1-1/2 wraps of fabric must remain
on the roller.
SETTING THE UP LIMIT POSITION
CAUTION: Do not allow the slat bar to wrap over the top
of the roller when the screen is rolling into the case.
The screen could be damaged.
ATTENTION: Évitez que la barre inférieure ne s'enroule au
dessus du cylindre lorsque l'écran est enroulé dans le caisson.
L'écran pourrait être endommagé.
Screen Travels Into Case Too Far: Turn the up limit switch screw
clockwise to decrease the amount of travel. Run the screen up to test
the stop position. If the screen does not stop properly, lower the
screen about one foot and turn the limit switch again. Repeat until the
desired position is set.
Screen Does Not Travel Far Enough Into Case: Turn the up limit
switch screw counterclockwise to increase the amount of up travel.
Run the screen up to test the stop position. If more travel is desired,
lower the screen about one foot and adjust the limit switch again.
Repeat until the desired position is set.
