Siemens SIPART PS2 Smart Electric Valve PositionerIt is currently the most widely used positioner for direct stroke and angle stroke actuators in process industries. The SIPART PS2 positioner, designed with a Macrolon, aluminum, or stainless steel housing, is suitable for all applications. Its proven universal design features a particularly flexible stroke range, intelligent diagnostics, and communication via HART, PROFIBUS PA, or FF. The SIPART PS2 can be integrated into the communication range via PROFIBUS PA, FF, or HART protocols, and can also be configured using SIMATIC PDM to clearly display and record stored trends, histograms, test runs, and operational data. The SIPART PS2 has extensive diagnostic capabilities. To issue costly fault warnings during operation, our positioner continuously checks the actuator and valve.

Here are the key features of the Siemens SIPART PS2 smart electro-pneumatic valve positioner that make it a standout in industrial automation:

Automatic Commissioning: Self-calibrates and configures itself, making setup fast and foolproof.

Exceptional Control Performance: Delivers precise valve positioning for optimized process control.

Low Air Consumption: Minimizes air usage during steady-state operation, reducing energy costs.

Integrated Safety Functions: Offers modes like Fail Safe, Fail to Open, and Fail in Place for enhanced system protection.

Comprehensive Diagnostics: Supports full/partial stroke tests, valve signature analysis, leakage monitoring, and predictive maintenance.

Versatile Enclosures: Available in polycarbonate, aluminum, stainless steel, and flameproof variants for harsh environments.

Multi-Protocol Support: Communicates via HART, PROFIBUS PA, and FOUNDATION Fieldbus.

Wide Compatibility: Works with single-acting, double-acting, linear, and part-turn actuators.

3. Frequently Asked Questions – Siemens SIPART PS2

1. How do I perform auto-calibration? 

Use the local pushbuttons or HART/Fieldbus interface to initiate the “Auto Setup” function. The positioner will automatically determine actuator travel limits and control parameters.

2. What does “OS--” on the display mean? 

It indicates a successful transmission of parameters or commands. If you see “MAN--,” the device is in manual mode and can be operated using the local buttons.

3. Can SIPART PS2 be used in hazardous areas? 

Yes, versions are available with ATEX, IECEx, FM, and CSA certifications for use in explosive environments.

4. What are the fail-safe options? 

You can configure the unit to Fail Close, Fail Open, or Fail in Place, depending on your process safety requirements.

5. How do I know if the valve is leaking? 

The diagnostics suite includes leakage monitoring. It detects internal or external leaks by analyzing air consumption and actuator behavior.

6. Is remote mounting possible? 

Yes, SIPART PS2 offers remote electronics options, allowing separation of the control unit from the actuator—ideal for high-vibration or high-temperature zones.

7. What communication protocols are supported? 

It supports HART, PROFIBUS PA, and FOUNDATION Fieldbus, making it highly adaptable to various control systems.

8. How often should I perform maintenance? 

Thanks to predictive diagnostics, the device alerts you when maintenance is needed—no fixed schedule required.
