Using the PV Input Shift
(1) Find the two points to shift and determine the PVs after the shifts are applied.
Example: Shift 500
°
C (temperature before shifting) to 550
°
C (temperature after shifting).
Example: Shift 1,000
°
C (temperature before shifting) to 970
°
C (temperature after shifting).
(2) Find the process value slope coefficient from the above results.
(970
−
550) / (1,000
−
500) = 0.840
* Do not yet set the Process Value Slope Coefficient parameter in the Digital Controller.
(3) Adjust the PV display on the Digital Controller to the point to be shifted.
Example: Adjust the PV to 500
°
C.
(4) Set the Process Value Slope Coefficient parameter to the value that you found in step
2.
Example: Set the Process Value Slope Coefficient parameter to 0.840.
(5) Read off the PV after the setting is changed.
Example: The PV will be displayed as 420
°
C.
(6) Find the difference between the anticipated PV (i.e., the PV after shifting) and the PV
that you read off in step 5.
Example: 550
°
C
−
420
°
C = 130
°
C
(7) Set the Process Value Input Shift parameter to the value that you found in step 6.
Example: Set the Process Value Input Shift parameter to 130
°
C.
After shifting
970°C
Before shifting
500°C
1000°C
200°C
1300°C
1,000°C is shifted to 970°C.
500°C
550°C
1000°C
500°C is shifted to 550°C.
