The input value is between 0 and 4095. The second field is the input A/D as a percentage of 4095. The third field is 4095 of A/D input as a percentage of 4095. You can use the values as a rough guide to where the input signal is relative to the full range. You can use his input as the raw input prior to scaling of an analog pressure sensor.

Each of the input A/D count sections have a voltage field. This field indicates the approximate voltage of the input based on the A/D, and the calibration factors on the factory cal page.

Overriding the feedback output field

When you override the feedback output field controls, the device uses the VO signal the 0 V to 10 V feedback signal to a third-party controller. To return the raw value of 0 to 4095 to the D/A for the Vo channel:
  1. Click the Get Feedback Output Raw Value button. If you click the Override AO 1 (VO) check box on the User Settings tab, and override the VO channel, the output on VO can be set by the user for debugging.
  2. Enter a value between 0 and 1000, 100%, in the feedback text box.
  3. Click Set Feedback Output Override Value button. The Vo output goes to a value between 0 V and 10 V.

Overriding the actuator output field

When you override the actuator output field, you can control the Io signal. The Io uses the 4 mA to 20 mA actuator control signal.

To return the raw value of 0 to 4095 to the D/A for the Io channel:
  1. Click the Get Actuator Output Raw Value button. If you click the Override AO 2 (Act) check box on the User Settings tab, and override the Io channel, the output on Io can be set by the user for debugging.
  2. Enter a value between 0 and 1000, 100%, in the Act Text box.
  3. Click Set Actuator Output Override Value button. The Io output goes to a value between 4 mA and 20 mA.

The two output sections also have a voltage field that displays the approximate voltage out based on the control value and calibration factors on the factory cal section.
