AUXILIARY OUTPUT SELECTION

This selection provides an mA output representing one of several control parameters. The display for auxiliary output viewing will be in engineering units for all but output. Output will be displayed in percent.

ATTENTION Other prompts affected by these selections: 4mA VAL and 20mA VAL.

ATTENTION Output cannot be configured when Three Position Step Control is used.

NO AUXILIARY OUTPUT

INPUT 1—This represents the configured range of input 1.

INPUT 2 represents the value of the configured range of input 2.

PROCESS VARIABLE—Represents the value of the Process Variable. PV = Input XxRatioX + BiasX

DEV

OUTPUT

SP

LSP 1

RSP

IN ALG1

CO RANGE 4-20mA

0-20mA

DEVIATION (PROCESS VARIABLE MINUS SETPOINT)— Represents –100 % to +100 % of the selected PV span in engineering units.

Zero deviation will produce a center scale (12 mA or 50 %) output. A negative deviation equal in magnitude to the Auxiliary Output High Scaling Factor will produce a low end output (4 mA or 0 %) output. A positive deviation equal in magnitude to the Auxiliary Output Low Scaling Factor will produce a high end output (20 mA or 100 %).

OUTPUT—Represents the displayed controller output in percent

(%). Cannot be used with Three Position Step Control.

SETPOINT—Represents the value of the setpoint currently in use (LSP1, LSP2, LSP3, RSP or CSP) and is shown in the same units as those used by the PV.

LOCAL SETPOINT ONE—Auxiliary output represents Local Setpoint 1 regardless of active setpoint.

REMOTE SETPOINT – Represents the configured RSP regardless of the active SetPoint.

INPUT ALGORITHM 1 OUTPUT—Represents the output from input algorithm 1.

AUXILIARY CURRENT OUTPUT RANGE—Allows the user to easily select 4-20mA output or 0-20mA output operation without the need for recalibration of the instrument.

ATTENTION Changing the Auxiliary Current Output Range will result in the loss of Field Calibration values and will restore Factory Calibration values.
