  • Luminaire diagnostic and configuration identification system
    Patent number: 6841944
    Abstract: A diagnostic and configuration identification system for an electrical device and a Photo-controller which automatically turns the electrical device on and off in response to ambient light levels. A detector senses the load drawn by the electrical device when it is on. A processor is responsive to the load drawn by the electrical device when it is on and programmed to detect a cycling fault condition based on the load drawn by the electrical device and to provide an indication of a cycling fault condition according several possible programming configurations. When no cycling or other fault condition is detected the processor determines the cycling fault condition indication configuration and then outputs a cycling signal indicative of the program configuration.

  • Luminaire diagnostic and configuration identification system
    Publication number: 20040124786
    Abstract: A diagnostic and configuration identification system (40) for an electrical device and a photocontroller (10) which automatically turns the electrical device on and off in response to ambient light levels. A detector (32) senses the load drawn by the electrical device when it is on. A processor (54) is responsive to the load drawn by the electrical device when it is on and programmed to detect a cycling fault condition based on the load drawn by the electrical device and to provide an indication of a cycling fault condition according several possible programming configurations. When no cycling or other fault condition is detected, the processor (54) determines the cycling fault condition indication configuration and then outputs a code signal indicative of the programming configuration.
