Patent ID: 7123144

Claim:
An automatic door system for operating a motor driven door, comprising: a motor operatively connected to a door; a controller for operating said motor; a activation switch, wherein said switch operates the said motor to control the door; a sensor switch for detecting a hazard condition, wherein said sensor generates a hazard signal when said sensor detects a hazard, wherein said hazard signal is one of a first mode and a second mode, and wherein said hazard signal is transmitted to said controller when the switch is activated; said sensor switch comprised of at least two conductors which contact each other upon physical pressure resulting from a hazard condition, whereby each conductor includes a means to connect the conductor at each end of the conductor such as to allow the passing of an electrical current through the conductor to test the continuity of each conductor; said controller testing for continuity of each of the said at least two conductors to determine a fault in any one of said conductors; said controller performs a diagnostic check to determine whether at least one of said sensor, a connection between said sensor and the switch, the switch, a connection between the switch and said controller, and said controller are functioning properly and if so, said sensor generates a signal, and wherein if any of said sensor, said connection between said sensor and the switch, the switch, the connection between the switch and said controller, and said controller are not functioning properly, the said signal is not generated and said controller switches to a fault mode.
