    As is well known, the Fisher Positioner DVC6200 is a valve mounted digital valve controller under Emerson, which can intelligently control the entire valve assembly. Control your process through important real-time information that can be accessed from any location in the circuit. It can also detect problems before they occur, helping you reduce maintenance time and costs, and improve the operational performance of the facility. This flexible instrument is suitable for various applications equipped with any host and valve, greatly reducing inventory and simplifying personnel training. But the Fisher locator DVC6200 needs to be debugged before use, what are the specific debugging steps? So today, let the technical editor of Hongli Instrument introduce the debugging steps of Fisher Positioner DVC6200, hoping to be helpful to everyone.

Step 1: Connect the Rosemount 475 manual operator

    1. Enter the interface and select HART;

    2. Enter after selecting online;

    3. If there is an alarm signal, select YES and enter;

    4. Select 'configure' from the online dropdown menu and press' enter ';

    5. Select the calibration menu and press enter;

    6. Select auto calibration;

    7. Select out of service from the warning menu;

    8. After selecting 'Continuue', enter and select 'travel control';

    9. Automatic valve calibration does not require operation, just wait until the interface shown in the figure below;

    10. Confirm with the OK button after automatic verification is completed;

    11. Select OK;

    12. Modify to in service status and complete the calibration.

Step 2: DVC Positioner Feedback Debugging Instructions

    1. Select manual setup from the configure menu;

    2. Select mode protection to change in service to OUT of service;

    3. Select to change the instrument mode;

    4. Select out of service. Return after entering;

    5. Warm reminder to select OK;

    6. Select outputs in the manual setup to set the locator feedback;

    7. Select output terminal;

    8. Select output terminal;

    9. Select enable and enter;

    10. Be sure to select send and complete the feedback usage settings. Remember to change the valve back to the in service state.

Step 3: Activate the locator calibration button

    1. Activate the function under the manual setup menu;

    2. Activate the function and select send to complete the setting of the junction box self travel calibration button;

    3. Press the debugging button for 3-10 seconds, and the valve will automatically perform stroke verification. The valve will automatically perform stroke verification.

Step 4: Adjustment of sensitivity

    If it is found that the valve under the Fisher valve positioner has oscillations or the valve action is too slow, it can be improved by adjusting the Tuning Set (simply understood as sensitivity) and clicking send. There are options for "C D E F G H I J K L M", with valve C reacting the slowest and valve M reacting the fastest. The faster the reaction, the more likely it is to cause vibration.

Step 5: Setting the Instrument Mode

    When performing locator verification and parameter adjustment, it is generally necessary to set the Instrument Mode to the Out Of Service (or Not In Service) state. After verification and adjustment, it must be put into In Service!

    The above introduces the debugging steps of the Fisher locator DVC6200. If you need to debug the locator later on, you can follow the above steps to avoid errors and obtain accurate and accurate data.
