Function
Process control including keeping airflow, pressure, and the amount of flow constant, can be
exercised using feedback signals (4 to 20mA, 0 to 10V) from a detector.
Or, it is also possible to always set 0 for integral and differential at terminal input.
Refer to "PID control instruction manual: E6581879” for details.
