4 Increase the KP value until the controlled system tends to oscillate.4 Slightly decrease the KP value until the oscillations are eliminated.4 Decrease the TN value until the controlled system tends to oscillate.4 Slightly increase the TN value until the oscillations are eliminated.5.3 PD controller4 Enter KP = 0.1, TV = 1 and derivative-action gain TVK1 = 1.4 Adjust the reference variable to the desired value in operating level.4 Use the cursor keys to change the output variable to a value at which the control valve slowlyopens and the error Xd becomes approximately zero.4 Switch to automatic mode.4 Increase the KP value until the controlled system tends to oscillate.4 Increase the TV value until the oscillations are eliminated.4 Increase the KP value until the oscillations appear again.4 Increase the TV value further until the oscillations are eliminated.4 Repeat this procedure several times until the oscillations can no longer be suppressed.4 Slightly decrease the KP and TV values to allow the controlled system to settle down.4 To eliminate the remaining system deviation, proceed as follows: switch to manual mode.Change the output variable until the error Xd = 0. Read the value displayed for the outputvariable and adjust the parameter Y.PRE (CNTR, C.PID) to this value.Note! Each change of the reference variable also changes the operating point!5.4 PID controller4 Enter KP = 0.1, TN = 1999 and TV = 1.4 Adjust the reference variable to the desired value.4 Use the cursor keys to change the output variable to a value at which the control valve slowlyopens and the error Xd becomes approximately zero.4 Switch to automatic mode.4 Increase the KP value until the controlled system tends to oscillate.4 Increase the TV value until the oscillations are eliminated.4 Increase the KP value until the oscillations appear again.4 Increase the TV value until the oscillations are eliminated.4 Repeat this procedure several times until the oscillations can no longer be suppressed.4 Slightly decrease the KP and TV value to allow the controlled system to settle down.4 Decrease the TN value until the controlled system tends to oscillate again. Now increase thevalue again slightly, so that the oscillations disappear.EB 6493-1 EN 67Start-up
