Parameter
Definition
DEVIATION (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 % to +100 % of the
selected PV span in engineering units.
FOR EXAMPLE:
Type T Thermocouple
PV range = –300 °F to +700 °F
PV span = 1000 °F
Deviation Range = –1000 °F to +1000 °F
If PV = 500 °F
and SP = 650 °F
then Deviation Display = –150 °F
Auxiliary Output = 42.5 %
When Deviation is selected, only one operating parameter
will be entered. This value represents the deviation level
that will produce 20 mA (100 %) output. Zero deviation will
produce a center scale (12 mA or 50 %) output. A
negative deviation equal in magnitude to the auxiliary
output high value will produce a low end (4 mA or 0 %)
output.
OUTPUT—Represents the displayed controller Loop 1
output in percent (%). Cannot be used with
3 Position Step Control.
SETPOINT—Represents the Loop1 value of the setpoint
in units of PV.
LOCAL SETPOINT ONE—Auxiliary output represents
Loop1 local setpoint one regardless of active setpoint.
INPUT ALGORITHM 1 OUTPUT—Represents the output
from input algorithm 1.
INPUT ALGORITHM 2 OUTPUT—Represents the output
from input algorithm 2.
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 in engineering units for Loop 2.
When Deviation is selected, only one operating parameter
will be entered. This value represents the deviation level
that will produce 20 mA (100 %) output. Zero deviation will
produce a center scale (12 mA or 50 %) output. A
negative deviation equal in magnitude to the auxiliary
output high value will produce a low end (4 mA or 0 %)
output.
OUTPUT 2—Represents the displayed controller output in
percent (%) for Loop 2.
SETPOINT 2—Represents the value of the setpoint in
units of PV for Loop 2.
LOCAL SETPOINT 2—Represents the value of local
setpoint #1 in units of PV for Loop 2.
