6.13.3. Scheduling dependent on an external signal

Scheduling dependent on the Y
whereas scheduling dependent on the Z-signal has to be configured with C51-6. In the cascade
control mode, C52-5 or C52-6 can also be set to implement adaptation for the master controller
loop.
The following parameters must be set before starting the adaptation algorithm:

The scheduling procedure dependent on an external signal is the same as the one dependent
on the controlled variable or output variable signal (see section 6.13.2.). The section factors,
however, are not calculated by the adaptation algorithm, but have to be entered manually in
the ADAPTATION PARAMETER level PA AdP.
The adaptation range set in the factory is 10% to 90 %. The section factors are assigned the
value 1.

6.13.4. Notes on adaptation

In a cascade control arrangement, adaptation must be first carried out in the follow-up or
secondary control loop. The operator has to open the cascade in the OPERATING level (press
B key). Then, a appears in the top right corner of the display. The control station can be put
either in the MANUAL or AUTOMATIC mode. After having carried out adaptation for the
follow-up control loop, the cascade must be closed (press B key) and the controller must be set
to the AUTOMATIC mode. Subsequently, adaptation can be implemented for the master
controller loop.
The factory settings for the controlled variable test range and the output variable test range for
adaptation are from 10 % to 90 %. If the operator modifies these two values, the two values
should always be the same in the beginning. Should the control station indicate insufficient
oscillation of the controlled variable during adaptation (cin 202, accept with A key), the output
variable test range (GWY

In case of an error, the adaptation algorithm provides different error messages. These are
