ABSTRACT:
A system and method for the automatic control of electrically operated gates is disclosed which includes a gate position transducer which provides an output signal in the form of pulses representing the incremental motion of the gate. The system also includes electronic circuitry responsive to the output signal of the position transducer for determining when the gate is either fully open or fully closed and also for determining when the gate motion is obstructed. The control system is fully automatic and does not require mechanical adjustments or the use of limit switches. Optional operating modes include an automatic close mode and the simultaneous operation of two gates.
