These tubular motors are provided with a system of electromechanical limit switches that
stops the feed when the awning or the rolling shutter get to the maximum opening or
closing limits. To adjust these limits and adapt them to any need, simply screw or unscrew
the two adjusting screws on the motor head. The limits of the limit switches are preset at
about three turns of the roller.

1. To decide which adjusting screw to fix, simply watch the direction
of rotation of the stop ring nut: if the stop ring nut pulled by the
roller goes in direction A, use the adjusting screw A to set the limit
switch in that direction. If it goes to the opposite direction (B), use
the adjusting screw B.
2. start up the awning or the rolling shutter in the direction in which
you wish to set the first limit switch. After a few turns the motor will
stop on the preset stop.
3. screw the adjusting screw suited to the direction (see point 1.) in
direction "+" till it gets to the chosen position.
