Abstract
PURPOSE: To provide the subject device wherein only in the case where the deviation between the automatic output and the manual output is in the defined range, the change-over to the manual operation is allowed thereby to prevent the occurrence of a great outer distrubance in the process and improve the reliability of the control system.
CONSTITUTION: At the time of automatic control, automatic control is selected by an automatic-manual converter 6, and a relay contact 11a is turned off and a relay contact 11b is on by a relay circuit 10. Upon this occasion, the output of a primary lag generator 5, that is, the automatic control output and a manual signal constantly supplied as input are compared with each other at a deviation announciator 9. Upon changing over to manual operation, the converter 6 is changed over to a manual control. Upon this occasion, when the deviation between the automatic signal and the manual signal is in an allowable range, the relay circuit 10 is turned on, and the realy contact 11a is turned on and the relay contact 11b is turned off, thus the output of the manual operator 3 becoming an operation signal.
