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 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 TC 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 HIGH
–999. To 9999. Floating
(in engineering units)
INPUT 1 HIGH RANGE VALUE—This value in
engineering units is displayed for all inputs but can
only be changed for inputs configured for linear or
square root transmitter characterization.
For Inputs with Linear or Square Root transmitter
characterization, you can scale the Input signal to
display the values you want for 0 % and 100 %.
EXAMPLE:
Process Variable = Flow
Range of Flow = 0 to 250 Liters/Minute
Actuation (Input 1) = 4 to 20 mA
Characterization (XMITTER 1) = LINEAR
Set IN1 HIGH value to 250
Set IN1 LOW value to 0
Then:
4 mA = 0 Liters/Minute
12 mA = 125 Liters/Minute
20 mA = 250 Liters/Minute
ATTENTION If Input 1 is selected as the PV
Source, then the range of the control Setpoint will be
limited by the range of units selected here.
