To calibrate the Flowserve Logix 500si series digital positioner:

  1. Press the QUICK-CAL button to easily and quickly calibrate the positioner on all actuators without physical stroke stops.
  2. The calibration process will be completed when the lights return to a sequence that starts with a green light.
  3. Commissioning is performed by simply setting a few switches and pressing the QUICK-CAL button. The Direct User Interface provides local access to positioner control without requiring multi-level menus, a handheld communicator or laptop computer.
  4. Fast calibration and setup can be made by simply pressing the Quick-Cal button. Interchangeable components (such as circuit board, piezo drivers, etc.) allow for easy maintenance.

The Flowserve Logix 500 SI Series I/P positioner requires multiple steps to calibrate. The following is a generic process outline to help you through it:

Tools and Equipment Needed:

  • Flowserve Logix 500 SI Series I/P positioner
  • Handheld communicator or calibration device (such as HART communicator)
  • Power supply (if necessary)
  • Appropriate documentation (e.g., the user manual for the specific model)

Calibration Procedure:

  1. Safety Precautions:
  • Ensure that the valve and actuator system is depressurized and de-energized before starting.
  • Follow all relevant safety guidelines and lockout/tagout procedures.
  1. Setup:
  • Connect the handheld communicator to the positioner. If using a HART communicator, connect it to the current loop.
  • Ensure that the positioner is properly installed on the actuator and that the air supply is connected and regulated to the correct pressure.
  1. Power On:
  • Power on the positioner and the handheld communicator. Wait for the devices to initialize.
  1. Enter Calibration Mode:
  • Use the communicator to navigate to the calibration mode on the positioner. This might involve accessing a specific menu or pressing a combination of buttons.
  1. Zero Calibration:
  • Set the input signal to 4 mA (or the lower range value, typically corresponding to 0% position).
  • Ensure that the valve is in the fully closed position.
  • Initiate the zero calibration process via the communicator. The positioner will adjust itself to recognize the fully closed position as 0%.
  1. Span Calibration:
  • Set the input signal to 20 mA (or the upper range value, typically corresponding to 100% position).
  • Ensure that the valve is in the fully open position.
  • Initiate the span calibration process via the communicator. The positioner will adjust itself to recognize the fully open position as 100%.
  1. Intermediate Points:
  • Some positioners may require calibration at intermediate points (e.g., 25%, 50%, 75%). Follow the prompts on the communicator to set these points if necessary.
  1. Verification:
  • After calibration, verify that the positioner correctly responds to the full range of input signals (e.g., 4 mA to 20 mA) and that the valve moves accurately to the corresponding positions.
  • Look for any alarms or error messages on the positioner or communicator display. Keep and Leave:.
  1. Save and Exit:
  • Save the calibration settings if prompted by the communicator.
  • Exit the calibration mode and return the positioner to normal operating mode.
  1. Documentation:
  • Record the calibration results and any observations for future reference.

Troubleshooting:

  • If the positioner does not respond correctly during calibration, check the air supply, wiring, and connections.
  • Refer to the user manual for specific troubleshooting steps related to your model.

Always refer to the specific user manual for the Flowserve Logix 500 SI Series I/P positioner you are using, as there may be model-specific steps or variations in the procedure.
