Installation SteCpH9: SET LIMIT SWITCHES AND FORCE CONTROLS Setting of Limit Switches A Setting Close Limit Switch (Figure 34): • Check that Magnetic Carriage Assembly is disengaged. • With garage door fully closed, slide Close Limit Switch until it is aligned with Carriage Assembly Magnet. • Tighten Set Screw. 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 Carriage Assembly Magnet. • Tighten Set Screw. Do not over-tighten. • Re-engage Magnetic Carriage Assembly. Setting Force Controls and Final Adjustment of Limit Switches WARNING • The garage door opens rapidly, and can cause serious injury or death. • Keep the path clear. • Position the ladder to the side of the Power Head so it is clear of all moving parts of the Opener and the door. • Set the door Opener to use the minimum force needed to open the door. A Pre-set Force Controls to midpoint between fully counter clockwise 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 distance from bottom of door to floor. Move Limit Switch same amount toward door and try again. - If door reverses after contacting floor, move Limit Switch toward Power Head and try again. - If door reverses before contacting floor, increase Close force and try again. - If door fails to move, check Safe-T-Beam® System. See Safe-T-Beam® Troubleshooting Guide on pg. 26, and Opener System Self-diagnostic Troubleshooting on 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 Switch toward Power Head. - If door opens completely, but motor continues to run, move Limit Switch toward door. • Tighten Limit Switch Set Screw. Do not over-tighten (strip) Limit Switch Set Screw. 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.
