Automatic Opening/Closing Force Adjustment
The opener will adjust the opening and closing force automatically so it operates at the most
efficient setting. To allow the opener to adjust the opening and closing force automatically,
operate the opener once after setting travel limits.
To operate the opener:
• Press the push button to open the door, until it reaches the
fully open position.
• Press the push button to close the door completely, until it
reaches the fully closed position.
You have now finished setting the opening and closing force.
In order to readjust the opening/closing force, you must first enter travel limit adjustment.
Force adjustment will proceed automatically after travel limit adjustment sequence.
Press
NOTE:
• After adjusting the Up/Down travel limits, the opener will re-adjust its opening and closing force during
the first opening and closing cycle. Therefore, it is important to pay attention not to obstruct the door
during the first opening and closing cycle after adjusting the travel limits. The opener has now finished
adjusting the opening and closing force.
• During the force adjustment, do not obstruct the door's travel or the safety beam sensor.
