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!
