<p>PROBLEM TO BE SOLVED: To omit an indicator and an operating part in order to reduce the work load of an operator an also to reduce the cost of a process controller while attaining a special function of the controller. SOLUTION: The process controller has the automatic and manual operation modes and is provided with an actuator manual setting device 6 which outputs a manual setting signal (d) in the manual operation mode by the increase/ decrease operations of a manual operating part 10, a bias setting device 2 which outputs a bias application value signal (b) that is varied according to the operation contents of the part 10 in the automatic operation mode, a deviation calculator 7 which calculates a deviation signal (g) from the signal (d) and a control command (c) received from an adder 3 in the manual operation mode and outputs the signal (g), an indicator 9 which indicates the inputted one of both signals (b) and (g), and a signal switch 4 which switches its contacts 4a to 4f according to the operation mode and outputs the signal (b) or (g) to the indicator 9.</p> |
