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