1. A control system for a dual swing gate, said dual swing gate having a master arm, a slave arm, a first linear actuator for actuating said master arm, a second linear actuator for actuating said slave arm, a first motor operatively attached to said first linear actuator so that said first motor drives said first linear actuator, a second motor operatively attached to said second linear actuator so that said second motor drives said linear actuator, said master arm and said slave arm each configured to pivot between an open position and a closed position when actuated by said first linear actuator and said second linear actuator, said control system comprising:

  • a. a first position sensor configured to observe the position of said master arm;

    b. a second position sensor configured to observe the position of said slave arm;

    c. a controller configured to actuate said first linear actuator and said second linear actuator during a closure process, said controller further configured to receive position data from said first position sensor and said second position sensor, wherein said controller is configured to determine the differential position of said master arm and said slave arm during said closure process and maintain a designated differential position between said master arm and said slave arm during said closure process so that said slave arm reaches said closed position before said master arm.
