General

The SIPART PS2 electro-pneumatic positioner is used to control the final control element of pneumatic linear or part-turn actuators. The electro-pneumatic positioner moves the actuator to a valve position corresponding to the set point. Additional function inputs can be used to block the valve or to set a safety position. A binary input is present as standard in the basic device for this purpose.

Features

• Simple installation and automatic commissioning (self-adjustment of zero and span)
• Simple operation with Local operation (manual operation) and configuration of the device using three buttons and a user-friendly two-line display
• Parameterization via SIMATIC PDM
• Very high-quality control thanks to an online adaptation procedure
• Negligible air consumption in stationary operation
• "Tight closing" function (ensures maximum positioning pressure on the valve seat)
• "Fail in place" function: Current position is retained on failure of auxiliary electrical power and/or pneumatic failure (does not apply in conjunction with SIL).
• Example: For an actuator with a volume of 8 liters, the typical position stability of a SIPART PS2 with "Fail in Place" is 0.3 %per hour.
• Numerous functions can be activated by simple configuring (e. g. characteristic curves and limits)
• Extensive diagnostic functions for valve and actuator
• Only one device version for linear and part-turn actuators
• Few moving parts, hence insensitive to vibrations
• External non contacting sensor as option for extreme ambient conditions
• "Intelligent solenoid valve": Partial Stroke Test and solenoid valve function in one device
• Partial Stroke Test e. g. for safety valves
• Full Stroke Test, Multi Step Response Test, Valve Performance Test for performance and maintenance evaluation of the valve
• Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases
• SIL (Safety Integrity Level) 2
