This prompt is part of the Input 1 Set up group.
At what power line frequency are you going to operate?
Selections

60 Hertz
50 50 Hertz
12.2.41 FSMODE
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
NO L
Controller stays in last mode (automatic or manual); output goes to Failsafe
value.
LACH Controller goes to manual mode; output goes to Failsafe value.
12.2.42 FUZZY
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
DIS
Disable the Fuzzy Overshoot Suppression.
ENAB Enables the Fuzzy Overshoot Suppression.
12.2.43 HYST
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.
