Siemens SIPART PS2 Valve Positioner Implementation Manual
The SIPART PS2 series is a smart electric valve positioner for pneumatic single‑stroke or double‑stroke actuators. It drives the actuator to the desired position, offers optional lock‑in functions, and includes self‑diagnostics, low air consumption, and programmable output features.
The manual covers application guidance, design details, working principle, configuration parameters, technical data, order information, wiring diagrams, and safety/diagnostic functions. It also explains how to set up HART or PROFIBUS‑PA communication and how to perform manual adjustments via the LCD and keys. This manual is written in Chinese.

Questions answered in these manuals
What is the advantage of the SIPART PS2 over traditional mechanical nozzle-flapper positioners?
The PS2 uses a microprocessor and piezo-valve for higher control accuracy and lower energy consumption, whereas mechanical controllers consume significantly more air regardless of adjustment actions.
Why is initialization required for the SIPART PS2?
Initialization is necessary to configure default parameters, determine valve direction of action, set zero and range points, define switching times, and optimize transient response based on the actuator type.
What is the stroke range that can be configured for the SIPART PS2?
The stroke range can be set between 5 mm and 130 mm.

What communication interfaces does the SIPART PS2 support?
It supports HART, PROFIBUS‑PA and Foundation Fieldbus (FF) communication interfaces.
From: Siemens SIPART PS2 Electric Valve Positioner User Manual
How is the SIPART PS2 powered in a 2‑wire system?
In a 2‑wire configuration the device draws its power from the 4–20 mA current loop.
