This is how to change mode:
PROCEDURE

Go to the “Categories Menu”.

Tap on the category “Temperature Control”.

Tap on the category “TAC/Manual”.

Tap on the sub-category “Select auto/expert”.

Choose between the dialog entries “Automatic mode” and “Expert mode”.

Confirm your choice by tapping on “OK”.
4.2.8 Sub-category: “Configuration auto”
You can only select this menu entry if “Automatic mode” is set.
4.2.8.1 Sub-category: “Find parameters”
4.2.8.1.1 Dialog entry: “Fast Identification”
Considering the small effort, the “Fast Identification” function of the controlled system provides you
with very quick and reliable adapted control parameters. These control parameters achieve a fast
and very accurate tuning performance. The more complex but also more precise identification “With
Preliminary Test” is only very rarely required.
Do not make any changes to the temperature control unit and to the application (temperature
control unit / external application) after your system has been started. Changes include e.g. filling /
draining process chamber, changing the mixer speed, change of position of Pt100 process control
sensor etc.
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 “Fast Identification”.

Confirm your choice by tapping on “OK”.

Read the message displayed and confirm it by tapping on “OK”.

Select the thermal fluid used from the list.

Confirm your choice by tapping on “OK”.

Choose between the dialog entries “Internal” and “Process (Cascade)”.

Confirm your choice by tapping on “OK”.

Enter a new setpoint using the number keypad that appears. This should be at least 10 K away
from the current setpoint.

Confirm your entry by tapping on “OK”. Setting of the control parameters using “Fast Identifica-
tion” starts and after a while a message appears on the display.

Read the message displayed and confirm it by tapping on “OK”.
4.2.8.1.2 Dialog entry: “With Preliminary Test”
In some complex applications, the “Fast Identification” of the control circuit may not yet lead to
optimum control. This can happen, in particular, if the hydraulic build-up cannot be adjusted to the
necessary circulation volumes. Further information on this is provided on page 36 in the Section »To
be noted when planning the test« .
A further optimization of control behavior can be achieved if you select the control parameterization
“With Preliminary Test”. With this, the control parameters within the set limits of the minimum and
