3.3 Limit Switch Adjustments
1. Be sure that power to the operator is OFF.
2. Push the gate to the open position. Adjust the OPEN limit nut so that it is activating
the OPEN limit switch.
3. Push the gate to the close position. Adjust the CLOSE limit nut so that it is activating
the CLOSE limit switch.
4. After adjusting the limit-nuts, be sure that the lock-plate is engaged in the slots on the
limit-nuts to prevent them from slipping.
5. Turn power on and activate the gate operator. If gate runs towards the close
position, turn power OFF and change direction switch (SW-1, switch 1). Turn power
ON and activate the gate operator.
6. Re-adjust the limit-nuts as necessary for full-open and full-close gate travel.
7. If the partial open feature is used (input to terminals 1 and 5), the partial open
distance can be adjusted by moving the magnetic pick-up across its slotted bracket.
Be sure that the magnet imbedded in the center limit nut is aligned with the magnetic
pick-up on the bracket.
