adjusted.(X.TUNE)!
Always observe the following sequence: X.TUNE → P.Q‘LIN → P.TUNE.
To operate the positioner as a process controller, implement the following steps:
setting up the position controller:
→
Specify the standard settings of the positioner and automatically adjust the position controller
(
X.TUNE).
setting up the process controller:
→
Start the P.CONTROL auxiliary function via the configuration menu in the main menu.
The P.CONTROL function also inserts the P.Q’LIN function into the main menu.
→
Implement the standard settings for the process controller under P.CONTROL.
Linearisation of the process characteristic
If this is a flow control process, the process characteristic can be linearised automatically:
→
Implement the P.Q’LIN function.
Self-optimization of the process controller
→
Implement the P.TUNE function.
