##. #
Selection applies digital filtering to
suppress noise effects on the PV.
The limits for this value are 0.0 to
32.0 seconds
NAMUR Output
(HART/DE only)
Disabled
Disabling sets the loop output and
burnout levels to the Honeywell
levels
Enabled
Enabling sets the loop output and
burnout levels to the NAMUR
levels

Delta Limit
(Dual Inputs only)
(HART/FF only)
####.##
User can configure the Delta
Limit. If the Critical Excess Delta
Detection has also been enabled,
the critical fault will be set when
the PV Delta (Sensor 1-Sensor 2
value) exceeds the Delta Limit."
Bumpless Damping
(HART/FF only)
##.# Damping value for the transition
of Loop Control between Sensors
when Loop Ctrl Mode is Split-
Range or Redundant
Hysteresis
(Dual Inputs only)
(HART/FF only)
###.##
Hysteresis value relative to the
MRV for the transition of Loop
Control between Sensors when
Loop Ctrl Mode is Split-Range
Break Detect*
Enable,
Disable
When enabled, adds a constant
bias value to the Sensor 2
measured value to equate it to the
Sensor 1 measured value at the
moment selected.
* Spurious readings may occur if Break Detect is off in delta mode
