What should I pay attention to when the automatic initialization of the valve positioner is unsuccessful?

DVC6200 smart valve positioners need to be initialized before they are put into use, and due to incorrect installation and use, they often run into trouble during the initialization process. place

There are several aspects that need to be noted:

1. Whether the air source is connected normally and whether the pressure is appropriate

2. Whether the mechanical connection between the actuator and the shaft of the valve positioner is normal, for the straight stroke, it is necessary to pay attention to the locking position of the drive pin on the feedback lever, for the corner

The stroke needs to be tightened with the locking screw.

3. Parameters 1 and 2, whether the settings are correct, and whether they are consistent with the proportion adjustment lever inside the positioner

4. First of all, manually drive the valve to act in the whole stroke to see if it is flexible, and pay special attention to whether the valve position displayed changes in the range of 5% to 95%, otherwise the adjustment is slippery

The dynamic friction clamping wheel is corrected, and the linear stroke is good to ensure that the valve opening is 50%, and the feedback rod is level, and the opening display is also 50%.
