Tune PAR Set Up Group
Introduction
Tuning consists of establishing the appropriate values for the tuning constants you are using so that
your controller responds correctly to changes in process variable and Set Point. You can start with
predetermined values but you will have to watch the system to see how to modify them. The
Accutune feature automatically selects Gain, Rate, and Reset on demand.
ATTENTION
Because this group contains functions that have to do with security and
lockout, we recommend that you configure this group last, after all other
configuration data has been loaded.
