Abstract
A microprocessor-based controller for regulating the operation of a fluid pump motor is disclosed, wherein the controller includes a protection circuit which prevents fluid over- or under-delivery conditions from occurring by shutting down the pump motor whenever the actual speed of the pump motor differs from a desired pump motor speed by more than a predetermined amount. A simulation means interconnected with the protection circuit simulates fluid over- or under-delivery conditions to test the accuracy of protection circuit operation.
