Automatic Tune Mode
Automatic Tune Mode is selected when it is desired to use the Pre-tune and Self-tune
facilities on a controller to assist the user in setting up Proportional band, Integral and
Derivative parameter values. Refer to the following Automatic Tune Mode table.
Pre-tune can be used to set Controller PID parameters approximately. Self-tune may then be
used to optimise the tuning. Pre-tune can be set to run automatically after every power-up
using the Auto Pre-Tune
@/
parameter in Setup Mode.
The AT indicator will flash while pre-tune is operating, and is continuously on
whilst Self-tune is operating. If both Pre-tune and Self-tune are engaged the AT indicator will
flash until Pre-tune is finished, and is then continuously on.
Navigating in Automatic Tune Mode
Press to select the next parameter in the table and or to set the value
required.
Hold down and press to return to Select Mode.
Note:
If there is no key activity for 2 minutes the controller automatically returns to operator
mode
