In many gateinstallations, this setting will need to be adjusted toovercome the weight and size of the gates.The stall force potentiometer on the circuit board con-trols the obstruction sensitivity (or the amount of forcethe opener will apply to an obstruction) before it auto-matically stops and reverses direction of the gate afterapproximately two seconds. Adjust the sensitivitybeginning at the factory default counter-clockwise posi-tion (fig. 43). Continue to incrementally increase theforce until the gate can open and close withoutobstructing under its own weight. |
