Abstract

PURPOSE:To speedily detect a machine in trouble by judging trouble even if the variation rate of the discharge pressure after the switching of the damper of a compressor does not largely deflect from the pressure variation rate before said switching. CONSTITUTION:A trouble monitoring program is stored into a program memory 42 in an operating machine number controller 4. The total supplied air quantity of the compressor at present is calculated in a central calculation processing part 41 and memorized in a data memory 43 up to the next sampling. The case of trouble is judged even if the variation rate of the discharge pressure after the switching of the damper of the compressor does not deflect largely from the pressure variation rate before the switching. Therefore, a machine in trouble can be detected speedily.
