Abstract

PURPOSE: Aimed at is to prevent erroneous judgement, and to protect power circuit with a high fidelity, devised is to carry out a cut-off operation against malfunction by an electronic computer's theoretical "AND operation" between the output of the theoretical judgement, and the output such as each detector relay used a shortcircuit or an earth-circuit.
