4.14 Fuzzy Overshoot Suppression

Fuzzy Overshoot Suppression minimizes overshoot after a setpoint change or a
process disturbance. This is especially useful in processes which experience load
changes or where even a small overshoot beyond the setpoint may result in damage
or lost product. It can be configured to apply to Loop 1, Loop 2, or both loops.

4.15 Accutune

There are several types of Accutune from which to choose in DC330E Models:
(TUNE) Demand Tuning—Tuning is done on demand
n by pressing the LOWER DISPLAY and
n by selecting prompt "TUNE" in the lower display,
n via digital input.
(SP) Setpoint Tuning—SP only tuning will continually adjust the Gain or
Proportional Band (P), Reset (I), and Rate (D) tuning constants in response to
setpoint changes.
(TUN+PV) Demand Tuning + PV Adapt—Provides TUNE On Demand tuning
plus PV adaptive tuning whenever a PV process disturbance of 0.3% span or
greater occurs.
(SP+PV) Setpoint Tuning + PV Adapt—Provides SP only tuning plus PV
adaptive tuning whenever a PV process disturbance of 0.3% span or greater
occurs.
