Cautions
It is dangerous during auto setup because the fully closed valve moves to fully open. Be
prepared in advance to prevent injury and effects on the process when the valve moves.
The Actuator Type is set to Linear and the Valve Closed Position is set to Down when
the valve is fully closed at the time of shipment unless there are other shipment setup
instructions. If factory setting (initial setup) is requested, check the settings at the time
of shipment. Configure settings as needed.
If auto setup fails, refer to 5-1-5, “Auto Setup Failure.”
The reverse action actuator fully closes, fully opens, and fully closes the valve when
auto setup starts. The direct action actuator fully opens, fully closes, and fully opens the
valve.Then, it is opened to between 20% and 25% and between 80% and 85%.
After auto setup, the valve moves to the opening appropriate to the input signal.
Check the following points before starting auto setup.
• Actuator Type
Linear (standard): Direct-acting actuator
Rotary/90°: When the distance between the feedback lever of the
rotary actuator (90°) and the pin is longer than the
distance from the valve shaft
Rotary/Other: When the distance between the feedback lever of the
rotary actuator (around 60°) and the pin is longer than
the distance from the valve shaft
Rotary(sub)/90°: When the distance between the feedback lever of the
rotary actuator (90°) and the pin is shorter than the
distance from the valve shaft
Rotary(sub)/Other: When the distance between the feedback lever of the
rotary actuator (around 60°) and the pin is shorter
than the distance from the valve shaft
• Valve Closed Position
DOWN (standard)
