12.2.41 FSMODE ( FAILSAFE MODE)
This prompt is part of the Control Set Up group.
This selection determines what state the controller will revert to if it goes into Failsafe.
Selections Definitions

Controller stays in last mode (automatic or manual); output goes to Failsafe
value.
LACH

12.2.42 FUZZY (FUZZY OVERSHOOT SUPPRESSION)
This prompt is part of the Accutune Set up group.
The UDC will use Fuzzy Logic to inherently suppress or minimize any overshoot that
may occur, when PV approaches SP, as a result of the existing tuning parameters. It does
NOT change the parameters.
Can be enabled or disabled independently of whether Demand Tuning is enabled or
disabled.
Selections Definitions
DIS
Disable the Fuzzy Overshoot Suppression.
ENAB
Enables the Fuzzy Overshoot Suppression.
12.2.43 HYST (HYSTERESIS - OUTPUT RELAY ONLY)
This prompt is part of the Control Set up group.
HYSTERESIS is an adjustable overlap of the ON/OFF states of each control output. This
is the difference between the value of the process variable at which the control outputs
energize and the value at which they de-energize. Only applicable for ON-OFF control.
Range of Setting: 0.0 to 100.0 % of PV (On/Off Control)
