Setting parameters individually
PID parameters can also be set individually according to the following value range:
●
P-Part (Xp)
2…500% of the measurement range
●
I-Part (Tn)
0…2000s, 0=no I part
●
D-Part (Tv)
0…1000s, 0=no D part

● By increasing the proportional band, the temperature/pressure deviation is lowered.
Using too great a proportion will result in temperature/pressure fluctuation.
● The integral action time defines the time that it takes for the temperature/pressure
deviation to return back to zero.
● The derivative action time speeds up control. Set the P and I parts while the value
for the D part is 0.
● Using too great a derivative action time will result in temperature/pressure
fluctuation.
Parameter adaptation
During adaptation, the burner control calculates PID parameters for process which is
controlled based on the characteristics.
