Abstract
A fault indication method for equipment includes receiving a fault signal indicative of a fault of a device; energizing a light emitter based on the received fault indication, in which a luminous material is made to fluoresce based on receipt of light emitted by the light emitter; detecting fluorescence of the luminous material by a light detector, and outputting a voltage and/or current indicative of the fluorescence; and providing a fault output signal when the voltage and/or current exceeds a predetermined value.
