Abstract : An on-line indicator connected to each fuse of an electrical circuit includes an LED which becomes illuminated if its protected fuse blows. Groups of these on-line indicators can be connected via on OR gate to a single master fuse status indicator which also includes an LED which becomes illuminated if any of the on-line indicators connected thereto has its LED illuminated. The circuitry can accommodate power supplies of different voltages of either polarity. Opto-isolators can be used to reduce stand-by current drain and to isolate the on-line indicators from each other. (Author)
