NOTE
•To protect your new investment, your opener is equipped with a Timer and Cycle Counter which work together to prevent any chance of heat damage to electrical circuits caused by too many cycles in too short a time.. If your Opener suddenly stops responding to the Wall Console
-Do Not Unplug the Unit - simply wait
10 minutes for the Timer/Cycle Counter to reset itself and try again..
a..Every 10 minutes you wait restores 5 cycles up to the maximum of 25.
•Unplugging the unit will prevent the Timer/ Cycle Counter from resetting.
DTest Door Opener:
•Run door up and down a few times using Wall Console and observe door travel..
•Repeat steps above as needed to set Limit Switch positions..
NOTE
•Little effort is required to turn the Force Adjusting Knobs..
•If the door stops moving while opening or closing, adjust the Open Force or Close Force Controls slightly clockwise (to slightly increase the force) and retry the step..
•The Open Force and Close Force Controls are to be set to the minimum force necessary to ensure the door smoothly opens fully and closes completely..
•The garage door will move slowly the first time it runs, until the Opener “learns” the type of door..
•Ensure the Magnetic Carriage Assembly is engaged and is between the two Limit Switches before operating the Opener..
EAdjust Open Force to minimum needed:
•Place door in closed position using Wall Console.
•Gently adjust Open Force fully counterclockwise (minimum force).
•Run Opener using Wall Console.
•Observe that door runs to Open Limit Switch.
–If not, adjust Open Force Control slightly clockwise, close garage door, and open it again.
•Repeat steps above until garage door runs smoothly from Close Limit Switch to Open Limit Switch..
