Abstract: A method for predicting a service state of a printing machine at a defined point in time includes: measuring a plurality of successive process values of a process parameter which is an indicator of the functionality of the printing machine; determining a plurality of successive scatter values which describe the spread of the measured process values within a predetermined time range; determining a local scatter minimum of the scatter values; determining a baseline, in that a baseline value is established that correlates with the value of the process parameter at the point in time of the local minimum and that does not change up until a new determination of a baseline; and determining a health value at a specific point in time, with a predetermined relation of the process value to the baseline value at this point in time. A service state is assessed upon the health value exceeding a predetermined threshold.

Abstract: In a method for monitoring a pump arranged in a flow path to pump a fluid, the temperature of a fluid is regulated by a tempering element during the operation of the pump. The regulation of the temperature may include detecting at least one status point which is formed from an energy supplied to the tempering element and a temperature slope of the tempering element. The status point may be determined in a hazard range by checking whether the status point is located outside of a normal status range, which means that the lifespan of the pump is limited.
