摘要

Arrangement for monitoring the condition of a system that the system at least one frequency converter (20), which is arranged, one or more loads (30) to food products, with the arrangementDetermining means (24), which are arranged, one of the aforementioned at least one frequency converter (20) has been taken or one or more loads (30) supplied amount of energy in the course of a predetermined period to determine, characterized in thatthe determining means (24) in addition, are arranged, which of the aforementioned at least one frequency converter (20) has been taken or one or more loads (30) in the course of energy supplied to determine the predetermined cycle is once again; and that the arrangement in addition,Comparison means (60), which are arranged, the specific quantities of energy to be compared to one another and the abnormal state of the system to determine if the compared amounts of energy at least about a predetermined limit value deviate from each other.
