To best adapt the controller parameters to the process, we recommend the following:
1.
Set values for controller parameter ("Values for user settings" field for linear curve or
"Parameter" field for segmented curve).
2.
Deflect the process.
"Simulation" field: Set function to "Manual" and enter a manipulated variable. Using the actual
value, you can observe how the process is deflected.
3.
Switch the function to "auto". Now you can observe how the controller returns the actual value
to the set point.
4.
If you want to set other parameters, press "Enter" and you come back to the "Values for user
settings" field. During this time, the controller continues to run in the background.
5.
Press the "Enter" key to return to the "Select simulation" field. You can continue or end
simulation here.
!
Note!
Always end controller simulation with "Simulation off" in the "Select simulation" field. Otherwise,
the simulation will continue to run in the background.

• Function
– auto
– manual
• Set
-2.00 ... 16 pH
• Act.
• y
-100 ... 100 % (only if
function = manual)
Function:
Here you can specify whether the
manipulated variable calculated by the
controller should be output for "Automatic" or
whether a manipulated variable y to be entered
by the user should be output for "Manual".
Control point:
Displays the current set point.
If necessary, you can change the set point. The
other points (start/end of neutral zone,
optimization points, control points) change
accordingly.
Act:
Displays the current actual
value/measured value.
y:
For the "Automatic" function: Displays the
manipulated variable determined by the
controller. With the "manual" function, you can
enter an actuating variable here.
Values < 0 % mean acid dosing, values > 0 %
mean base dosing.
