Selections or
Range of Setting
FAILSAFELO TYPE—Selects the motor position you want
the actuator to go to when input signal is below the low end
range value or on loss of input signal.
NOTE: Failsafe condition occurs when the input exceeds its
low end range value by 3%, or when the input signal goes to
zero. For input types 0 to 20mA, 0 to 5 V, and 0 to 10 V
there is no failsafe condition at the zero value.
Last Position—Actuator motor remains at last position.
LAST
Up—Actuator motor moves to full scale value.
UP
Down—Actuator motor moves to zero value.
DOWN
User selected value—Actuator motor moves to a customer-
USER
defined value.
* Allows setting of failsafelo input value.
default = DOWN
0 to 100% FAILSAFELO INPUT VALUE—(FailsafeLO Type USER
only) Selects the motor position you want the actuator to go
to when input signal is below the low end range value or on
loss of input.
default = 0
Range is from 0 to 100%.
INPUT CHARACTERIZATION— Selects a characterization
LINR
type that causes the actuator to characterize a linear input
SQRT
signal to represent a non-linear input.
CUST
Linear— Provides linear characterization of the input signal.
Square Root— Provides square root characterizations of
the input signal.
Custom— Custom characterization. Selecting custom
allows you to create a twentieth order characterization of
default = LINR
input value (x) and associated shaft position (y).
NOTE: Selecting CUST input characterization causes the
following prompt CUSTOM to be displayed.
Equal percentage – Sets the characterization as explained
EQUL
in Equal Percentage Valve Characteristic on page 42.
QUIK
Values are read-only.
USER
Quick opening - Sets the characterization as explained in
Quick Opening Valve Characteristic on page 43. Values are
read-only.
default = EQUL
User-configurable – Lets you create your own
characterization using the following Xn VAL and Yn VAL
prompts.
Input Value— as a percentage of input range. Defaults are
0 to 100 %
in increments of 5%.
Shaft Position Value— as a percentage of position range.
0 to 100 %
Defaults are in increments of 5%.
