ADJUSTMENT STEP 2

Adjust the Force

The force, as measured on the closing edge of the door, should not exceed 400N (40kg). If the closing force is measured to more than 400N, a Safety Infrared Reversing Sensor must be installed See step 3 on page 27.

The force setting button is located on the back panel of the motor unit. The force setting regulates the amount of power required to open and close the door. If the forces are too light, door travel may be interrupted by nuisance reversals.

Locate the button on the back panel of motor unit. Push the button twice to enter into Force Setting Mode. The LED (Indicator Light) will flash. Push the wall control or the programmed remote control that was shipped with your opener. The door will travel to either the OPEN or CLOSE position. Push the button again, the door will travel to the opposite position. Push the button again if the LED is stilling blinking.

The door must travel through a complete cycle UP and DOWN in order for the force to be set properly. If the unit reverses before it reaches the Open or Close Limit repeat the process. The LED (indicator light) will stop flashing when the force has been learned.

Note: If unable to set limits return to page 25.
