PID Adjustments
calculated PID parameters. To do this, a chart recorder or data logging device is
needed to provide a visual means of analyzing the process. Compare the actual
process response to the PID response figures with a step change to the process.
Make changes to the PID parameters in no more than 20% increments from the
starting value and allow the process sufficient time to stabilize before evaluating
the effects of the new parameter settings.
MANUAL TUNING
between process cycles. This procedure is an alternative to the controller’s Auto-
Tune function. It will not provide acceptable results if system problems exist.
1. Set the Proportional Band (ProP) to 10.0% for temperature models (T16) and
2. Set both the Integral Time (Intt) and Derivative Time (dErt) to 0 seconds.
3. Set the Output Dampening Time (OPdP) in Output Module 2-OP to 0 seconds.
4. Set the Output Cycle Time [CYCt] in Output Module 2-OP to no higher than

control results or induced oscillations may cause system problems. In these
applications, Manual Tuning is an alternative.
7. If the process is stable, decrease Proportional Band setting by two times and
8. Fix the Proportional Band to three times the setting that caused the oscillation
9. Set the Integral Time to two times the period of the oscillation.
10. Set the Derivative Time to 1/8 (0.125) of the Integral Time.
11. Set the Output Dampening Time to 1/40 (0.025) the period of the oscillation.
In some unusual cases, the Auto-Tune function may not yield acceptable

with this step until the process oscillates in a continuous nature.
