Abstract

A method for monitoring operating condition of an apparatus (1) comprising a rotating equipment. The method comprises the following steps repeated at certain time intervals: recording vibration data by a vibration detecting unit (11) associated with the apparatus (1) at a certain sampling frequency, which vibration data is representative of a vibration acceleration of the rotating equipment; obtaining a frequency spectrum of the vibration data by converting the vibration data using Fourier transform operation to a representation in a frequency domain; and performing an analysis of a plurality of selected narrow individual predetermined frequency bands (61-65) of the obtained frequency spectrum for determining whether the apparatus (1) is running or not, and/or for triggering an alert when a maximal magnitude of the frequency spectrum within any of said frequency bands (61-65) exceeds a corresponding individual threshold value (21-30).
