Method for setting alarm levels for a machine

A system for setting alarm levels for a machine comprising:

• the system configured to define at least one condition indicator reflecting the condition of the machine with respect to a defect to be monitored of the machine, the at least one condition indicator being defined from the measurements of machine kinematic data,
• the system further configured to record, by one or more sensors, measurements of machine condition data and of process related parameters during a predetermined period during which the machine is operating normally,
• the system further configured to perform a first calculation to calculate condition indicator values for the at least one condition indicator for each recorded machine condition data measurement,
• the system further configured to determine a graph representing the at least one condition indicator value, on a vertical axis, as a function of a first process related parameter chosen from the measured process related parameters,
• the system further configured to divide the graph into operating classes along a horizontal axis, each operating class being representative of a different operating condition of the machine and having upper and lower boundaries for each operating class,
• the system further configured to perform a second calculation to calculate an alarm level value for each operating class based on the statistical characteristics of the condition indicator values for each operating class,
• the system further configured to set the determined alarm level value in the graph at a horizontal axis midpoint of each operating class.
