ABSTRACT:
A control system for an electrical device includes a controller that outputs an AC device enable system when one or more monitored sensors are in a proper state for operation of the electrical device. The control system may also include a sensor signal integrity checking circuit that outputs a validation signal when the sensor is one of a discrete set of acceptable sensor states. The control system may also include a current monitor that monitors the current draw of the electrical device and compares the current draw to a range of acceptable current draw levels and durations and disables operation of the electrical device when the current draw falls outside of the range.
