Edit Sensor Selection Screen: This screen displays the sensor that this output currently references.
Typically, no action is taken in this screen. But if you need to change the sensor that this output
references, you can select a different sensor for this output in this screen.
Note: If you change the sensor that an output references to a sensor with a different Sensor Type, the
default setup values for the output change, and you must set the output up again.
11. If you are not changing this output’s sensor, simply press to save the current sensor
selection and return to the Analog Output Setup Start screen.
To change the sensor this output references, press or to select the new sensor that this
output references. Then press to save the new sensor selection and return to the Setpoint
Selection screen (SP or dSP). If the new sensor has a different Sensor Type from the previously
referenced sensor, repeat the output setup procedure for this output.
The screen example shows Sn-2 as the selected Sensor for Output 3.
Analog Output Setup Start Screen
After you have set up this analog output, you can go to another Output Setup Start screen, the Sensor
Setup Start screen, or return to the Main screens.
12. Press to scroll through the remaining Output Setup Start screens and return to the Sensor
Setup Start screen, or press and simultaneously to return to the System 450 Main
