Configuration
To configure this item, refer to Section 3 – Configuration.
Two-loop and Cascade Operation
Accutune can be used on either or both loops. However, while one loop is operating
by SP tuning, the configuration of either loop cannot be changed. When one loop is
operating by PV adaptive tuning, the other loop can have its configuration changed.

TUNE On Demand tuning will work for all control algorithms except
ON/OFF. Process line out is not required.
TUNE On Demand tuning works for integrating processes.
SP tuning will work only for algorithm PID a or PID B selections; i.e., it
will NOT work with ON/OFF, Three Position Step, or PD+MR control
algorithms.
SP tuning can tune on all local or computer setpoints except ramping
setpoints; i.e., cannot be done during SP Ramp or SP Program or
when using remote setpoint.
Tuning is done in automatic mode.
Tuning can be monitored or reconfigured using communications
option.
Tuning can be enabled via digital inputs.
Tuning can be aborted by going to manual mode or disabling via
configuration.
When tuning is in progress, a large T appears in the upper display
and disappears as soon as tuning is completed.
Can tune two independent loops.
Setpoint changes can be made during operation. The setpoint at the
time tuning starts is captured and Tune runs until completion, then
proceeds to the new SP value following the completion of tuning.
