ABSTRACT:
An electronic failure detector includes an electronic processor having processor inputs and processor outputs, a memory connected to one of the inputs, a logic circuit having logic circuit inputs and logic circuit outputs, the logic circuit inputs and logic circuit outputs being connected to others of the processor inputs, and instructions, stored within the non-volatile memory, for causing the processor to perform a logic check of the logic circuit and to generate a first signal on the processor output if said logic check is true, and to generate a second signal on the processor output if said logic check is false.
