Parameter
Definition
AUXILIARY OUTPUT SELECTION provides an mA output
representing any of twelve control parameters. The display
for auxiliary Output viewing will be in engineering units for
all but output. Output will be designated in percent (%).
Other prompts affected by these selections: "4 mA VAL"
and "20mA VAL".
NO AUXILIARY OUTPUT
INPUT 1—This represents the configured range of input 1.
FOR EXAMPLE:
Type "J" Thermocouple (0 to 1600° F)
0° F display = 0% output
1600° F display = 100% output
INPUT 2 represents the value of the configured range of
input 2.
PROCESS VARIABLE 1—Represents the value of the
Process Variable for Loop 1. PV = Input 1 + Bias
DEVIATION 1 (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 to +100% of the selected
PV span in engineering units for Loop 1. FOR EXAMPLE:
Type "T" Thermocouple
PV range = –300 to +700° F
PV span = 1000° F
Deviation range = –1000 to +1000° F
If PV = 500° F
and SP = 650° F
then Deviation Display = –150° F
Auxiliary Output = 42.5%
NOTE: A deviation of 0° F yields an auxiliary output of
50%.
OUTPUT 1—Represents the displayed controller output in
percent (%) for Loop 1.
SETPOINT 1—Represents the value of the setpoint in
units of PV for Loop 1.
PROCESS VARIABLE 2—Represents the value of the
process variable for Loop 2.
DEVIATION 2 (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 to +100% of the selected
PV span for Loop 2.
See Example at DEV 1.
