    INSTALLATION Step 8 Dual Gate Setup There are two options for dual gate communication: wired or wireless. Follow the directions according to your application. Do not use wired and wireless communication simultaneously. Wired dual gate applications will have a longer battery standby time than wireless applications. Wireless dual gates will require the installation of two control boxes, one for each operator arm.

See Adjust Limits section. 3 MOVE GATE Buttons: The MOVE GATE buttons will either open or close the gate when the operator is in Limit setting mode. See Adjust Limits section. 4 BATT FAIL: When AC power is OFF and battery voltage is critically low the gate will latch at a limit until AC power is restored or batteries voltage increases.

  • Page 29: Manual Release

    OPERATION Manual Release In case of a power failure, the operator can be disengaged from the gate. With an operator, the release action may sometimes feel stiff/jerky, which is normal and has no effect on function. NOTE: It is normal for the operator to run slow right after a disconnect or complete loss of AC/ battery power (the operator will need to run a complete open and close cycle).
