Regarding Siemens positioners

I purchased a Siemens positioner online, installed it and carried out the initialization process. After that, I found that in manual mode the water outlet valve was closed. When switching to automatic mode, the valve opened automatically. Now I want the valve to remain closed while the system is in automatic mode. Please help me with this, thank you

Is your locator double-acting or single-acting?

Both the DCS and the positioner can have their action modes set to forward or reverse; check whether the valve is of the FO or FC type, and confirm the action mode for each side

After restoring the factory settings, the valve remains in the closed state when displayed manually; once switched to automatic mode, the valve opens automatically
