Abstract: Method for error detection and for local limitation of a cause of the error in an installation for machining a workpiece which is preferably formed at least in sections from wood, a wood material, and/or a synthetic material, the installation having several segments, comprising the steps: Detecting a workpiece parameter in at least two segments of the installation; determining whether there is an error on the basis of the detected workpiece parameter; if there is an error, identifying in which of the at least two segments of the installation the error is present for local limitation of the cause of the error; and outputting a signal containing the information regarding which segment the error is in.

Abstract: In a method for controlling a fuel injection system of an internal combustion engine with at least one combustion chamber, wherein the fuel injection system comprises a high pressure pump, whose flow rate is controllable, a control parameter of the high pressure pump is evaluated during the operation of the internal combustion engine. Said control parameter makes a detection of a bottleneck with the high pressure pump with respect to fuel quantity possible.
