摘要：An operating mode of an electro-pneumatic converting unit is stored in advancein an electro-pneumatic converting unit operating mode storing unit. A blockage locationidentifying function is provided in a calculating unit. The operating unit monitors the

magnitude of shift and the direction of shift of the control output, relative to the nozzleback pressure, through the blockage location identifying function, and identifies whethera blockage has occurred in the fixed orifice or the nozzle/flapper mechanism based onthe magnitude of shift and direction of shift of the control output, relative to the nozzleback pressure, and based on the operating mode of the electro-pneumatic convertingunit, stored in the electro-pneumatic converting unit operating mode storing unit. Anelectro-pneumatic converting unit operating mode identifying function may be providedin the calculating unit, and the operating mode of the electro-pneumatic converting unitmay be identified through this function, and the identification result may be stored in theelectro-pneumatic converting unit operating mode storing unit.
