Parameter Definition
Fuzzy
Suppression
Fuzzy Overshoot Suppression —Can be enabled or
disabled independently of whether Demand
Tuning or SP Tuning is enabled or disabled.
Disable Disables Fuzzy Overshoot Suppression.
Enable The instrument uses Fuzzy Logic to suppress or
minimize any overshoot that may occur when PV
approaches SP. It will not recalculate any new
tuning parameters.
Accutune
Accutune III
Disable Disables the Accutune function.
TUNE Demand Tuning —If TUNE is selected, and tuning
is initiated through the operator interface or digital
input (if configured), the algorithm calculates new
tuning parameters and enters them into the
tuning group. This tuning requires no process
knowledge and does not require line out for
initialization.
Duplex
Output
Duplex Accutuning III
NOTE: These prompts only appear when a
duplex output type has been configured.
Manual Tune manually using LSP 1 and LSP 2 values.
LSP 1 is used to derive tuning parameters
associated with HEAT (output > 50 %). LSP 2 is
used to derive tuning parameters associated with
COOL (output < 50 %).
Auto Tuning is performed automatically on both HEAT
and COOL sequentially. LSP 1 is used for HEAT
tuning and LSP 2 is used for COOL tuning. To
initiate tuning, either LSP 1 or LSP 2 must be in
use.
