The extension and retraction limit switches have been preset at the factory.
In general, we advise you to avoid readjusting these switches.
In some cases, to enable proper alignment of the displayed image on the
screen, you may need to adjust the extension of the screen or the mask. If
adjustment to the extension is necessary, carefully follow these instructions.
Modifying the screen extension
You can increase the extension of the screen and mask up to 3" / 7.6 cm
past the factory preset stop, or you can decrease the extension by
approximately 4" (10 cm) from the factory preset stop.
Do not attempt to
modify the screen extension beyond these recommended amounts.
Improper adjustments to the screen's deployment setting will cause screen
problems.
The limit switches are located on the left side of the screen roller tube inside
the housing.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the white "Down" extension limit located on the motor's
head, left side of the screen tube. Use an electrician style
screwdriver or 4 mm hex key to turn this switch in a counter-
clockwise direction. If the power is applied to the motor, the
screen will drop incrementally as the switch is turned.
Note: One complete turn of the switch will make approximately a
1" (2.5 cm) change in the screen stop position.
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down and
then press "Stop."
2. Locate the white "Down" extension limit switch located on the left
side of the screen tube. Use an electrician style screwdriver or 4
mm hex key to turn the switch in a clockwise direction.
Note: One complete turn of the switch will make approximately a
1" (2.5 cm) change in the screen 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.

Caution
Improper adjustment of
any of the motor's limit
switches can cause
irreparable damage to
the screen and related
components, resulting
in voiding the factory
warranty.
Caution
The screen is fully
retracted when the
batten stops just inside
the bottom of the
housing. Do not
attempt adjustments
with the "yellow" (UP)
retraction limit switch
that will further retract
the screen. Incorrect
adjustment of the
switch will cause
severe and permanent
screen damage. This
switch also controls the
signal for the door
closure. Improper
adjustment could cause
the door to close
prematurely on the
screen. Consult the
factory if you have any
questions.
