If the motor shaft rotation direction does not coincide with the required one, disconnect
electrical network and swap the connection of phase conductors L1 and L2.
4. Limit Switch Adjustment
At the beginning of the limit switch adjustment the awnings of roller shutter should be
in the fully lowered position.
The limit switches are factory set at approximately 2 turns.
This sequence of the limit switch adjustment is suitable for the right-hand and left-hand
installation of the motor.
The limit switch adjustment is performed by means of adjusting screws 1 on the head part of the
motor (Fig.12). Next to the adjusting screws there are arrows 2 that indicate the direction of the
motor shaft rotation (not to be confused with the direction for movement of the awnings of the
roller shutter!). The rotation of adjusting screw corresponding to the arrow towards "+" increases
the duration of the rotation; the rotation towards "-" decreases the duration of the rotation.
Up Limit Switch Adjustment:
•
Enable the motor to lift the awning. The motor will automatically stop through the activation
of the "up" limit switch; in this case the awnings of the shutter should not move up to the up-
per limit position;
•
Holding down the button of the switch, rotate the adjusting screw towards "+", waiting for the
awnings reaches the upper limit position.
Down Limit Switch Adjustment:
•
Enable the motor to lower the awning; and using rotation of corresponding adjusting screw
towards "-" waiting for the awning stop when it reaches the lower limit position;
•
Continue lowering the awnings; and using rotation of adjusting screw towards "+" wait for the
awning reaches the lower limit position.
After limit switch adjustment it is required to perform trial start and make sure that adjustment is
correct. If the limit switch adjustment is incorrect, repeat the adjustment.
The limit switch adjustment is performed by the wrench from the set of the motor. Do
not use electrically operated tool for the limit switch adjustment!
