Abstract
A control system and method for ensuring proper closure of a dual swing gate. The control system employs position sensors for monitoring the position of each gate arm. A “differential position” is maintained between the arms during closing to ensure proper sequencing. The control system regulates the speed of the master arm and the slave arm to ensure that the differential position is maintained throughout the closure process.
