Abstract
A method for use with a pumping system includes receiving a pump command signal for starting a pump; initiating a valve command signal for opening a valve, in response to the receiving the pump command signal; receiving a valve sensor signal indicating that the valve is open; and initiating a pump start command signal, in response to the received valve sensor signal.
Claims17
A method for use with a pumping system, the method comprising:
- receiving a pump command signal for starting a pump;
- initiating a valve command signal for opening a valve, in response to the receiving the pump command signal;
- receiving a first valve sensor signal, from a sensor coupled to the valve, indicating that the valve is open;
- initiating a pump start command signal, in response to the received first valve sensor signal indicating that the valve is open;
- initiating a pump stop command;
- receiving a pump signal indicating that the pump has stopped;
- sending a close valve signal to close the valve;
- receiving a second valve sensor signal indicating that the valve is not closed;
- and
- generating an error signal in response to the second valve sensor signal.

A pumping system comprising:
- control circuitry configured to:
- receive a pump command signal for starting a pump;
- initiate a valve command signal for opening a valve, in response to the pump command signal;
- receive a first valve sensor signal, from a sensor coupled to the valve, indicating that the valve is either open or closed;
