Ziegler-Nichols method for the optimization of a PID controller:
Parameters
: Setpoint, P-Band, Reset time, Derivative time
The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and program

ming details. Choose control upwards or downwards.
Control upwards or downwards
Setpoint:
User-defined process value for the selected parameter.
P-Band:

trol) the set-point, within the dosing intensity is reduced from 100% to
0% to reach the setpoint without overshooting.
