Abstract: A pump system comprises a bilge pump powered by an electric motor and a controller controlling the electric motor. The controller is configured to determine if the pump system is malfunctioning. In response to determining that the pump system is malfunctioning, the controller is configured to control the electric motor according to a predetermined routine configured to rectify the malfunction. A pump system comprises a first bilge pump including a first electric motor configured to power the first bilge pump and a first controller controlling the first electric motor and a second bilge pump including a second electric motor configured to power the second bilge pump and a second controller controlling the second electric motor. The first and second controllers are in signal communication with one another.

Abstract: A system for a marine vessel includes a first peripheral device including a controller, and a second peripheral device. A first serial bus connects the controller to the second peripheral device. At least one sensor is coupled to the controller via a second serial bus. The first peripheral device's controller can do one or more of the following: automatically control switches in the first peripheral device in response to information from the sensor; stage the first peripheral device upon start-up of the system; diagnose a malfunction of the first peripheral device and control the second peripheral device in response to determining that the first peripheral device is malfunctioning; and/or report a status of the first peripheral device over the serial bus.
