  • Page 247: Tuning And Control

    This chapter explains PID control and supplies some starting PID values and tuning instructions to help appropriately set control parameters in the PPC system. For more information on PID control, consult the Watlow Anafaze Practical Guide to PID. The control algorithm dictates how the controller responds to an input signal.

  • Page 248: Control Algorithms

    On/Off control turns an output on or off when the process variable reaches limits around the desired setpoint. This limit is adjustable; Watlow Anafaze controllers use an adjustable spread. For example, if the set point is 1000°F, and the spread is 20°F, the heat output switches On when the process variable drops below 980°F and Off when the process rises above 1000°F.

  • Page 249: Figure 6.2-Proportional Control

    However, a process which uses only proportional control settles at a point above or below the setpoint; it never reaches the setpoint by itself. This behavior is known as offset or droop. offset Figure 6.2 Proportional Control Doc.# 30002-00 Rev 2.3 Watlow Anafaze...
