Step 6: Limit Switch Adjustments
1 By using the mechanical disconnect, manually open the gate to its full open position (Note
direction of limit nut travel).
2 Remove control panel cover and locate the rotary limit switch assembly. Disengage the
retaining bracket from the limit nuts.
3 Depending on the “hand” of the operator, rotate the open limit nut until it makes contact with
the open limit switch lever and trips the open limit switch activation button.
4 Adjust the other limit nut so that it is near the open limit nut but not touching.
5 Manually close the gate to its full closed position.
6 Disengage the retaining bracket and rotate the close limit nut until it makes contact with the
close limit switch lever and trips the close switch.
7 Re-engage the retaining bracket into both limit nuts and also re-engage the mechanical
disconnect.
