Abstract

PURPOSE: To enable to detect easily a disconnection and a short-circuit of an electric apparatus with use of a potential detecting circuit with a potential detection level, two or more resistors and a fault signal generator.
CONSTITUTION: In an ordinary state of an electric apparatus 32, and output terminal 61 of a potential detecting circuit 81 is in "H" state and an output terminal of a potential detcting circuit 82 is in "L" state when the electric apparatus 32 is not driven. If there is a disconnection in the electric apparatus 32, each output terminal 61, 62 of the potential detecting circuit 81, 82 is in "L" state. When the electric apparatus is driven but has no fault, each output terminal 61, 62 is in "L" state. When a short-circuit happens in the electric apparatus, the output terminal 61 of the potential detecting circuit 81 is in "H" state and the output terminal 62 of the potential detecting circuit 62 is in "L" state. A fault signal generator 25 separates the signal from the potential detecting circuit 81 and generates the signal for a disconnection or a short-circuit according as the electric apparatus is driven or not.
