How to obtain the reverse positioning of FOSS locator?

1 First of all, Flowserve Logix520 series valve positioner is equipped with operation keys and DIP configuration switches. All basic operations can be completed through the local operation panel of the positioner, and the correct position characteristics can be selected.

2. Secondly, thirdly, the four switches need to be set together, and the field setting is linear, that is, the position of the actuator is proportional to the input signal. Note that when the third switch is set to linear, the fourth switch fails.

3. Then repeat the above operation, move the valve to 100% opening, and record. After the manual setting is completed, the light returns to the sequential FOSS positioner from the green light for reverse positioning.
