Patent ID: 8861156

Claim:
An apparatus for controllably providing operating power to a load, comprising: a control board assembly configured to receive an input and provide an output based, at least in part, on an operating mode selected by a user; a user interface allowing the user to select the operating mode for the control board assembly; and an electronic overload relay electronically interconnected with the control board assembly and a contactor relay, the contactor relay being selectively capable of supplying operating power to a load; wherein, upon the control board assembly receiving a start input: the contactor relay is enabled to supply operating power to the load; the electronic overload relay senses one or more aspects of the operating power supplied to the load; and based at least in part on the sensed one or more aspects of the operating power, the control board assembly operates a status relay outputting an indication of operating status of the load, wherein the indication of operating status of the load indicates proof of flow.
