If the derivative time is too short the controller would not react quickly to process disturbances A long derivative time means more derivative action If the derivative time is too large the con troller would react too dramatically to process disturbances creating rapid process oscillation A process which is very dynamic such as pressure and flow applications is more efficiently controlled if the derivative action is turned off because of the oscillation problem which would result Tuning Tuning as with any PID loop requires tuning each parameter sepa rately and in sequence To achieve good PID control manually you can use the trial and error method explained below Tune the Proportional Band Set Integral Time 0 off Set Derivative Time 0 off Start with a large Proportional Band value which gives very sluggish control with noticeable offset and tighten by decreasing the value in half Analyze the process variable If the control is still sluggish tight en by decreasing the value in half again Continue with the same pro cedure until the process starts to oscillate at a constant rate Widen the Proportional Band by 5096 or multiply the setting 1 5 times From a cold start test and verify that the Proportional Band allows maximum rise to setpoint while maintaining minimum overshoot and offset If not completely satisfied fine tune the value up or down as needed and test until correct The Proportional Band is now tuned
