  • Method and apparatus for diagnosing a twin-coil, bi-stable, magnetically latched solenoid
    Patent number: 5497093
    Abstract: Electrical and mechanical operation of a bistable magnetically latching solenoid is diagnosed by monitoring induced voltage across the one of a pair of solenoid coils not energized. Energization of one of the pair of coils induces voltage across the other of the coils not energized and plunger actuation in response to energization induces another voltage therethrough. The various induced voltages are distinguishable as between those caused by energization of a coil or motion of the plunger.
