    27 Controller 27.2 Controller optimization Optimum The optimum adaptation of the controller to the control loop can be tested by adjustment recording the starting phase. The following diagrams (referred to the PID action) indicate where the adjustments may be incorrect, and how they can be rectified. It can be seen that a slower control action with higher stability can be achieved by increasing either the proportional band Pb or the reset time rt.

    28 Manual operation Description In manual operation, outputs K1, K2 and K3 can be operated by hand, independently of the controller. Manual operation is only possible if it has been configured first. Chapter 26.4 “Controller options - C211”, page 76. The output level limiting is effective during manual operation (except for limit controllers).
