Abstract

PURPOSE: To improve response by automatically switching the signal of main control circuit to a gain matching with an operation mode.
CONSTITUTION: Signal V1 from main control circuit 11 is inputted to multiplier 15 and switching signal KV2 from change-over circuit 16 switched by pump operation mode signal 17 is also inputted to multiplier 15. Then, feed water valve 14 is controlled via driving mechanism 13 by output MV of multiplier 15. Consequently, the signal of main control circuit 11 is automatically switched to a gain matching with an operation mode, thereby improving response.
