Do Not over-tighten.B Setting Open Limit Switch:• Manually open garage door to full open position.• Slide Open Limit Switch until it is aligned with CarriageAssembly Magnet.• Tighten Set Screw. Do not over-tighten.• Re-engage Magnetic Carriage Assembly.Setting Force Controls and Final Adjustment ofLimit SwitchesA Pre-set Force Controls to midpoint between fully counterclockwise and fully clockwise (Figure 35).B Adjust the Close Limit Switch:• Press Wall Console to close garage door.– If door does not close completely, measure distancefrom bottom of door to floor. Move Limit Switchsame amount toward door and try again.– If door reverses after contacting floor, move LimitSwitch toward Power Head and try again.– If door reverses before contacting floor, increaseClose force and try again.– If door fails to move, check Safe-T-Beam® System. SeeSafe-T-Beam® Troubleshooting Guide on pg. 26, andOpener System Self-diagnostic Troubleshootingon pg. 27.• Tighten Limit Switch Set Screw. Do not over-tighten(strip) Limit Switch Set Screw.C Adjust Open Limit Switch:• Press Wall Console to open garage door.– If door does not open completely, move Limit Switchtoward Power Head.– If door opens completely, but motor continues torun, move Limit Switch toward door.• Tighten Limit Switch Set Screw. Do not over-tighten(strip) Limit Switch Set Screw.WARNING• The garage door opens rapidly, and can cause seriousinjury or death.• Keep the path clear.• Position the ladder to the side of the Power Head so it isclear of all moving parts of the Opener and the door.• Set the door Opener to use the minimum force neededto open the door.NOTE• Little effort is required to turn the ForceAdjusting Knobs.• If the door stops moving while opening orclosing, adjust the Open Force or Close ForceControls slightly clockwise (to slightlyincrease the force) and retry the step.• The Open Force and Close Force Controls are tobe set to the minimum force necessary toensure the door smoothly opens fully andcloses completely.• The garage door will move slowly the firsttime it runs, until the Opener “learns” thetype of door.• Ensure the Magnetic Carriage Assembly isengaged and is between the two LimitSwitches before operating the Opener.Close Limit Switch(door fully closed)Carriage(disengaged) MagnetSwitchSwitchMagnetOpen Limit Switch(door fully open)Carriage(disengaged)Figure 34 Setting Limit SwitchesHI LO HI LOOPENFORCE CLOSEFORCEForce ControlsFigure 35 Making Force Adjustments
