4.10 Accutune III
Introduction
Accutune III (TUNE) may be used for self-regulating and single integrating processes.
This autotuning method is initiated on-demand, typically at initial start-up.
There are no other requirements necessary, such as prior knowledge to the process
dynamics or initial or post tune process line-out to setpoint or manual output.
Also, the setpoint value is not required to change in order to initiate the tuning process,
but the controller must be in the Automatic mode to start tuning. The process need not be
in a static (lined out) state and may be dynamic (changing with a steady output).
Configuration check
Make sure:
• TUNE has been enabled see to Subsection 3.6 - Accutune Set Up Group for details.
Tuning indicators
A “T” will show in the leftmost alphanumeric of the upper display until tuning is
completed.
