ABSTRACT:
Systems for diagnosing fault conditions in a plurality of inputs are useful in many applications. Advantageously, such systems allow a technician to quickly and clearly identify the fault condition. The subject invention includes a plurality of sensors to produce a plurality of sensor signals. Each of the sensor signals is in one of a normal state or a fault condition and has an associated pin number. A plurality of indicator lights are also each associated with one of the sensor signals. A display individually indicates each pin number associated with a sensor signal in the fault condition. Each of the indicator lights associated with one of the sensor signals in the fault condition is flashed. The indicator light associated with the sensor signal for which the associated pin number is indicated by the display is steadily illuminated.
