Abstract
In a method for error containment and diagnosis in a fluid power system the fluid volumetric flow of the overall system or at least a part thereof or a quantity dependent thereon is detected as a measurement quantity respectively during an operating cycle and is compared with stored references. In each case at the point in time of a deviation or change in the deviation from the reference the method finds at which component or at which components (through) in the system an event has occurred influencing the fluid consumption in order to then to recognize same as subject to error. In the case of such a deviation or change therein and the simultaneous occurrence of several activities influencing fluid consumption by several components (through) a process of exclusion is performed, in which during the following activities involving at least one of such components (through) a check is made to see whether a deviation or a change in the deviation has occurred, and in each of such further examination steps the components involved are excluded from such further examination, if no deviation or change in the deviation takes place.
