The limits are not set by the factory, but a tool is provided with each motor so you can set the “Up” and “Down” end limits.
Please note: This can take up to 30 complete 360 degree rotations of the limits screw on the motor head.
Please note: When adjusting the limits setting screw the
Plus(+) will add travel. Minus(-) will reduce travel.
Setting the down stop limits is best done with two people, one near the stop button on the controller inside the house, the other person adjusting the down stop limit screw (shown in picture below) until the curtain stops in the correct position.
Please note: The Box Locking System must be set at the correct position. When the locking system is set in the correct position it will be almost imposable to raise the curtain from the out side, this is a simple set to make your shutter more secure.
