Several options of controller parameterisation are available:
1.
Fast identification (valid as from E-Grade Exclusive)
2.
With preliminary Test (valid as from E-Grade Exclusive)
3.
Estimate control parameters (valid as from E-Grade Basic)
1. Fast identification:
Delivers a relatively fast and reliable control parameter with which a rapid regulation
with a relatively high constancy can be reached.
First, start temperature control and run for some minutes to achieve a suitable stable
set-point. During the following do not carry out any changes on the system (e.g. filling /
emptying the reactor core, change of agitator speed, change of the process sensor
position etc.).
After activating this function, a table with thermal fluids is displayed. Select the
appropriate thermal fluid here. If your thermal fluid is not listed in the table, please
select
no specification.
If your thermal fluid is not listed, the controller assumes a
thermal fluid with characteristics, which normally results in an overshoot-free (slower)
control. After selecting the thermal fluid, you are asked, whether you want to identify
and control
Internal
or
Process (cascade or set-point tracking)
. You are then requested
to enter a set-point. Please note, that the identification is only successful, if the new
set-point differs from the current set-point by at least 10 K. In the status field of the
chart display (60), the information
Temp. + Ident.
active is displayed.
