Abstract (en)
[origin: WO2015080886A2] A self-monitoring valve module responsive to an actuating signal for admitting liquid into a sump container to test a sump pump includes an electrically-actuated valve responsive to the actuating signal to establish flow into the container, and a flow sensor which provides an output signal indicative of liquid flow through the valve, and a monitoring circuit which provides a fault signal indicating failure of the valve when the actuating signal is not calling for actuation of the valve and the flow sensor output signal indicates flow through the fluid conduit, or when the actuating signal is calling for actuation of the valve and the flow sensor output signal indicates no flow in the fluid conduit.
