  • Page 77: On/Off Control Setting

    5.3.2 ON/OFF control setting When a measurement value (PV) being controlled reaches the target value (SV), the control output is turned off. Then, the control output is turned on when the measurement value (PV) goes beyond the peak value, approaches the target value (SV), and goes beyond it. This move is repeated at a particular position. The adjustment sensitivity (sensitivity range), in this case, is defined as the difference between the point where the control output turns off (measurement value) and point where the control output turns on.
  • Page 78 Continued from the previous page 2) How to set the adjustment sensitivity In order to stabilize the equipment operation, a particular range is provided for switching on and off in the ON/OFF control. This range is called “adjustment sensitivity (hysteresis or sensitivity range).” What is described below is how to set the adjustment sensitivity after the control method is changed to the ON/OFF control in the bank setting.
