If the roller shutter does not reach the bottom of the opening or there is still a gap between the slats when the motor stops, you need to increase the bottom limit of the motor.

To identify the correct switch, the arrows on the motor correspond with the rotation direction of the axle on the front. When the shutter is going down, the front of the axle moves up, and vice versa.

Use the hexagonal adjustment tool and turn towards the plus sign.

This will mean that the shutter will go down more.

If the roller shutter goes down completely but the motor doesn’t stop, you need to decrease the bottom limit of the motor. If this happens, you can see that the springs start to roll around the axle again which causes stress and they will break after a while.

Use the hexagonal adjustment tool and turn towards the minus sign.

This will mean that the shutter will go down less. Also Note the correct position of the springs for optimal operation.

If the roller shutter is not going all the way up, you need to increase the top limit of the motor. Use the adjustment tool and the corresponding switch, and turn towards the plus sign. This will mean that the shutter will go up more.

If the shutter goes up to the maximum height but the motor still keeps working, you need to decrease the top limit of the motor. As you can see the plastic stops are pushed up and the motor is still working which decreases the lifetime of the motor.

Use the adjustment tool and turn in towards the minus sign.

This will mean that the shutter will go up less.

 

Adjusting the limits when the motor is already programmed

To adjust the limits when the motor is already programmed, you first need to reset the remote control and then follow the programming and limit adjustment sequence.

To reset the remote control, switch the power off and wait for 5 seconds and then switch back on.

Then press and hold all the three buttons until motor gives a feedback.

Now press and hold the small button at the back of the remote control for 7 seconds until two feedbacks are given.

 

Programming and limit adjustment:

Step 1: With the motor powered on, press and hold the up and down buttons simultaneously until you get feedback. Feedback means the motor jiggling up and down to confirm the action.

The motor is in programming mode now.

Step 2: First you need to make sure the rotation direction of the motor is correct. This means the shutter going up when pressing up and vice versa.

If the shutter goes up when you press up, wait for 5 seconds until you get one feedback.

If the shutter goes down when you press up, reverse the direction by pressing and holding the stop button until feedback is given. if it takes more than 5 seconds to reverse direction, cut the power supply and restart from step 1.

Step 3: Reach the required bottom limit by pressing down. Also Note the correct position of the springs for optimal operation.

Step 4: Store the bottom limit point by pressing and holding Stop button until feedback is given

Step 5: Reach the required top limit by pressing up. Also note that If the shutter goes up to the maximum height but the motor still keeps working, you need to decrease the top limit of the motor. As you can see the plastic stops are pushed up and the motor is still working which decreases the lifetime of the motor.

Step 6: Store the top limit point by pressing and holding Stop button until two feedbacks are given.
