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 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.
IN1 LOW
–999. To 9999. Floating
(in engineering units)
INPUT 1 LOW 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 0 %. See example above.
ATTENTION The control setpoint will be limited by
the range of units selected here.
RATIO 1
–20.00 to 20.00
Floats to 3 decimal places
RATIO ON INPUT 1—Select the Ratio value you
want on Input 1.
BIAS IN1
–999. to 9999.
(in engineering units)
BIAS ON INPUT 1 — Bias is used to compensate
the input for drift of an input value due to
deterioration of a sensor, or some other cause.
Select the bias value you want on Input 1.
