<p>The device has switching valves (5, 7, 9, 11) e.g. membrane valves, for opening and closing an associated medium inlet pipe (13, 15, 17, 19). Control valves (51, 53, 55, 57) e.g. magnetic valves, open and close the switching valves. Unit for detecting pressure (61, 63, 65, 67) e.g. extensible measuring sensor, detects pressure in a control air line (43, 45, 47, 49) between the valves. Another unit is arranged for detecting the pressure in the pipe. An evaluation unit (69) recognizes control malfunctioning of the control valves by using the detected pressure in the control air line. An independent claim is also included for a method for recognizing control malfunctioning in a device for filling of liquid, in particular beverages in a container or for rinsing the container.</p> |
