Abstract
A pump control system includes a controller coupled to first and second pressure sensors. The sensors couple serial pressure related information to the controller. The controller can evaluate respective liquid levels, in response to received pressure related information from the sensors. A current sensor coupled to the controller can provide signals indicative of operation of one or more pumps coupled to the controller. The controller includes circuits to detect the presence of predetermined, prioritized, faults and to emit a wired or wireless fault indicator in response thereto.
