TRANSMITTER CHARACTERIZATION—
This selection lets you instruct the controller
to characterize a linear input to represent a
non-linear one. If characterization is
performed by the transmitter itself, then
select LIN (Linear).
ATTENTION Prompt only appears when a
linear actuation is selected at prompt IN1
TYPE.
FOR EXAMPLE:
If input 1 is a 4 to 20 mA signal, but the
signal represents a type K H thermocouple,
then configure K H and the controller will
characterize the 4 to 20 mA signal so that it
is treated as a type K thermocouple input
(high range).
Parameter definitions are the same as in IN1
TYPE.
IN1 HI 603
−999 to 9999
floating in
engineering units
INPUT 1 HIGH RANGE VALUE in
engineering units is displayed for all inputs
but can only be configured for linear or
square root transmitter characterization.
Scale the #1 input signal to the display value
you want for 100 %.
EXAMPLE:
Process Variable = Flow
Range of Flow = 0 to 250 Liters/Minute
Actuation (Input 1) = 4 to 20 mA
Characterization (XMITTER) = LINEAR
Set IN1 HI display value to 250
Set IN1 LO display value to 0
Then 20 mA = 250 Liters/Minute
and 4 mA = 0 Liters/Minute
ATTENTION The control setpoint will be
limited by the range of units selected here.
