Step (5): Autotuning(AT) Function
A. Once installed in the field, carry out selftuning to allow the controller to determine the optimum AT
parameters.
B. AT calculation will choose the optimum PID Parameters based on the controllers auto tuning algorithm.
C. The maximum value of the process curve should be about 80% of the range of instrument detection.
D. Before the program is not started (fixed value control STA=0), it is better to carry out AT around the maximum
value of the process curve (SV=0.3). E. In LEVEL1 process, press SET key several times to reach AT option,
Step (6) Manually modifying PID parameters. (Optional Fine Tuning)
Use the below duie to change the P, I, D values for fine tuning of manual tuning (LEVEL 2)
Example: To Set four groups as shown in the above figure
In the first group, there are five stages: the first stage, the step temperature is C1, and the step time is T1.In the
second segment, the end temperature is C2 and the end time is T2.In the third stage, the step temperature is C3
and the step time is T3.In the fourth section, the step temperature is C4 and the step time is T4. In paragraph 5,
the step temperature is C5 and the step time is T5.
The second set of seven sections: the first section, the end temperature is C7, the end time is T7 .In the second
segment, the end temperature is C8 and the end time is T8. In the third section, the end temperature is C9 and
the end time is T9. In the fourth segment, the end temperature is C10 and the end time is T10.In paragraph 5,
the step temperature is C11 and the step time is T11. In the sixth paragraph, the step temperature is C12 and
the step time is T12.In the seventh section, the end temperature is C13 and the end time is T13. The third set of
three sections: the first section, the end temperature is C15, the end time is T15. In the second segment, the end
temperature is C16 and the end time is T16. In the third section, the end temperature is C17 and the end time is
T17.
The fourth set of five segments: the first segment, the end temperature is C19, the end time is T19.In the second
segment, the end temperature is C20 and the end time is T20.In the third section, the step temperature is C21
