Abstract
A closing mechanism controller includes contactor operating logic that generates a software or firmware based closing mechanism command signal. The controller also includes hardware interlock circuitry that generates an interlock signal, the hardware interlock circuity being configured to compare an interlock signal to the software based closing mechanism command signal and to provide an enable signal to the closing mechanism when the interlock signal matches the closing mechanism command signal.
