Logix 3400IQ Digital Positioner Calibration


Re-Cal Button:
Calibration of the Logix 3400IQ digital positioner is very straightforward. The Re-Cal button will perform a
stroke calibration procedure, but the DIP switches are no longer used. The parameter CONTROL_FLAGS
must be configured over the fieldbus network prior to using the Re-Cal button. Once the positioner is
properly configured, press and hold the Re-Cal button for five seconds. The Re-Cal button is only
operational when the FVPTB is in OOS mode.

Stroke Calibration: To perform a stroke calibration, complete the following steps:

Set the Transducer block to OOS.

Ensure the positioner is configured correctly. Refer to previous section.

Check the Periodic Update box under the Custom tab, in the Transducer block window.

Ensure air supply and valve tubing matches configuration.

Select Perform a stroke calibration procedure option under the CALIBRATE parameter in the NI

Configurator.

Click the Write Button.


The valve should now go closed, open, then to a mid-stroke position for a few seconds. CALIBRATE will
return to normal operation at the completion of the calibration process.
