General
Signal and setting values are converted and adjusted as a percent-
age value of the signal.
A slow process will normally not be critical for the setting of P-part
and I-part.
However, if the process is quick, more careful setup is required.
A general balancing might be:
- Check max. and min. settings
- Increase the integration time so that it is not mixed up with the
balancing
- Reduce Kp to start with
- Start the process
- Adjust Kp until the process starts fluctuating and is constantly
fluctuating
- Adjust Kp to half the value
- Adjust Tn down until the process starts fluctuating again
- Adjust Tn to double values
