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 40 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
maximum setpoint are determined. Temperature control is then also carried out to the setpoint
limits in some circumstances.
Before starting the automatic controller parameterization, verify the correct setting of the mini-
mum and maximum setpoint. A limitation to the actually used operating temperaturerange is
advantageous. 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 mixerspeed, change of position of
Pt100 process sensor etc.
Since the working temperature range can sometimes be very large, finding the parameters takes
correspondingly longer in this mode. The control defines up to three temperature setpoints and
automatically processes them one after another. One of these is below room temperature, one
roughly at room temperature and one above room temperature, if the setpoint limits allow this.
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.
