Steps to Calibrate a DVC6200 Controller

On receiving a DVC6200 the instrument mode is “In Service.” Follow these simple steps to get your device up and running.

  1. Hook up a HART® communicator to the DVC6200 in parallel with a 4-20 mA loop across the “loop” terminals
  2. Apply a 4 mA signal to the DVC and power up the HART communicator
  3. First, put the instrument in “not in service” mode. Do this by entering the menu ‘configure’, then ‘detailed setup’, then ‘mode and protection’, then ‘instrument mode’
  4. Choose “not in service” and press enter
  5. Hit the home key to return to the main menu
  6. Now enter ‘configure’, then ‘guided setup’, then ‘setup wizard’
  7. Entering ‘setup wizard’ will start you through configuration prompts asking for information about the actuator and valve you are working with
  8. Enter the actuator manufacturer, type, size, and supply pressure requirements as requested by the communicator
  9. When asked, go ahead and send the factory defaults to begin with (fine tuning can be adjusted later)
  10. After completing the setup wizard portion, the communicator will prompt you to start the auto-travel calibration portion
  11. When asked for adjustment method for output bias choose manual
  12. The communicator will automatically stroke the valve to 100% travel and 0% travel and adjust the output bias
  13. When it asks for 50%, adjust the mA input to 12 mA and proceed with the remainder of the auto-travel calibration procedure
  14. Afterwards the communicator will prompt you to return it to “in service” mode; do so
  15. Stroke the valve completely and make sure your valve opens linear to your 4-20 mA input signal

NOTE: Different device descriptions and DVC styles may have slightly different terminology. Path give is based on 375 or 475 communicator structure.
