Abstract
The occurrence of a condition indicative of an impending shutdown causes the closing of a switch which completes a circuit powering an indicator and a relay coil. The powering of the relay coil causes the closing of the associated contacts which completes a circuit for powering the relay coil independent of the initial closing of the switch so that the indicator remains powered/lit until manually disabled. The powering of the coil also results in the establishing of a summary fault signal. A timing relay is used to avoid false signals at start up.
