PROCEDURE

Before setting the control parameters, make sure that the temperature control unit has reached
the set setpoint and has been controlling the temperature at this setpoint for a few minutes. Do
not stop the temperature control.

Do not make any changes to the temperature control unit and the application during parameter
determination.

Go to the “Categories Menu”.

Tap on the category “Temperature Control”.

Tap on the category “TAC/Manual”.

Tap on the sub-category “Configuration auto”.

Tap on the sub-category “Find parameters”.

Tap on the dialog entry “Estimate Control Parameters”.

Confirm your choice by tapping on “OK”.

Read the message and confirm it by tapping on “Yes”. The current control parameters will be overwritten.

Select the thermal fluid used from the list.

Confirm your choice by tapping on “OK”.

Read the message displayed and confirm it by tapping on “OK”.

Enter the filling volume using the number keypad that appears.

Confirm your entry by tapping on “OK”.

Tap twice on the “Arrow” touchbutton to return to the category “Temperature Control”.

Tap on the category “Process/Internal”.

Choose between the dialog entries “Internal” and “Process (Cascade)”.

Tap on “OK” to confirm your choice.
4.2.8.2 Sub-category: “Control Dynamics”
You can choose between a faster tuning performance with a possible and accepted small tempera-
ture overshoot and a tuning performance without temperature overshoot. The default setting is
“Fast, small overshoot” .
The overshoot always refers to the leading temperature. If, for example, you have activated the process
temperature control, this will be the leading temperature. Contrary to this, the bath or flow temperature
must always be ahead of the process temperature. To achieve the best possible transmission of energy
the largest possible temperature difference between bath and flow temperature and the process temper-
ature is required. Note the illustration “Representation of an optimum process temperature control” .
→ From page 48, section »Temperature control to process temperature« . This can only ever be done
with the largest possible volume flow of thermal fluid. In the setting “Fast, small overshoot” , the combi-
nation of high thermal fluid flow rate and the superbly designed control electronics hardly ever results in
an overshoot, while reaching the setpoint as quickly as possible. Contrary to the mode “Faster, small
overshoot” there is the setting “Without overshoot”. The target temperature is approached more cau-
tiously and thus aperiodically. It takes longer to adjust to the selected setpoint. The statement “without
overshoot” is only valid with little external disturbance influence. Please note the specifications. → Page
34, section »To be noted when planning the test« .
The adjustment behavior can be selected at any time without reactivating the “Find control parameters”.
