If you have no experience in setting control
parameters, these defaults

process
are intended as an aid to adapting the
controller behaviour to the process. Select a default
and use the "controller simulation" (see below) to check
if these settings are relevant for your process.
Enter all the characteristic values yourself with the

Select controller simulation
Here, you can switch a configuration loop on or off. The
hold is removed with an active controller simulation.
Simulation on
: The characteristic values entered in the
previous field are used in the next field to simulate the
controller behaviour.
Off
: Press "E" to leave the controller simulation.

Controller simulation
Function
: Here, you set whether an actuating variable
calculated by the controller ("auto"), or an actuating
variable y entered by the user ("manual") is to be
output.
Set
: 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.
Actual
: Displays the current actual/measured value.
Y
: With the "auto" function: displays the actuating
variable determined by the controller. With the "manual"
function, you can enter an actuating variable here.
Values < 0 % mean a dosing of acid, values > 0 %
mean a dosing of alkali.
