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.
