The T-Series motors – T06, T20 & T35 have a mechanical progressive limit system that is adjusted by rotating the appropriate limit screws on the motor head.
As the limits are not set by the factory, a tool
is provided with each motor so the “Up” and “Down” end limits can be set onsite.When adjusting the limits setting screw the Plus (+) will add travel. Minus (-) will reduce travel.
Please note:
This can take up to 30 rotations of the limits screw on the motor head.
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.
To ensure the top stop limit is set correctly,
stop the curtain 2 slats down from the bottom of the head box by using the limit screw adjustment, then adjust the curtain height again by using the limit screw adjustment to stop the curtain 3cm from the bottom of the head box.
If the shutter height limit is not set correctly,
the bottom bar of the curtain has a bottom bar V stopper each side, which stops the curtain from going completely into the head box, but this causes the motor to jam and stop, this should be avoided and the up limit set to stop the curtain before this happens
