About this task

You can use the CFM entry position table to input the values into the controller. To update the CFM entry positions, see the following steps.

Procedure

  1. To download the values to the controller, click CFM Table tab > Set CFM Entries > Set Feedback Entries buttons.
  2. Select the This is Phoenix Valve Data and the Auto Populate FB Entries check boxes. The CFM values are accurate to the feedback sensor position and not the actuator position. Calibration of the completed feedback occurs in the actuator.
  3. Ensure the correct actuator stroke time value is set and click the Calibrate FB Sensor button. Wait until the valve moves from 100% to 0% and to each of the defined feedback positions. The tool computes the gain and offset for the feedback sensor and also enters the correct position values for each of the defined feedback positions.
  4. When you enter all the values into the table, the Set CFM Entries and Set Feedback Entries buttons are enabled. To update the CFM and feedback controller entries, click each button.
    Note: Do not select the OEM actuator check box.
