Information for the Operator 0-6 Positioner SIPART PS2/SIPART PS2 PA C79000-G7476-C150–01
Introduction 1 Introduction 1.1 General information about the device The SIPART PS2 positioner is used to position and control pneumatic actuators. The instrument operates electropneumatically, compressed air is used as the auxiliary power. SIPART PS2 PA In the SIPART PS2 PA version, the positioner is used as a component in a digital process automation system. It communicates with the master as a slave via the PROFIBUS PS field bus.
Introduction Housing The electronics including the display and the position feedback and the valve manifold are integrated in the housing. The housing is available in two variations: ❑ Plastic housing for double-acting actuators ❑ Metal housing for single-acting actuators Degree of protection The instrument has degree of protection IP65. Explosion protection The intrinsically safe version can be operated in hazard area zone 1 or zone 2.
Introduction 1.2.1 PROFIBUS DP and PROFIBUS PA Transmission technology The PROFIBUS PA ( PA = Process Automation) is a variant of the PROFIBUS DP (DP = Distributed Peripherals) which is widely used in manufacturing. The PROFIBUS PA makes use of special transmission technology and therefore meets the requirements of process automation and process engineering. This transmission technology is defined in the international standard IEC 1158–2.
Introduction Master Master (class 1) (class 2) PROFIBUS DP PROFIBUS PA J Slaves (field devices, distributed I/Os, lower–level controls, gateway to PROFIBUS PA) Fig. 1-1 Typical PROFIBUS automation system Fig. 1-1 shows a section of a typical PROFIBUS automation system. The control system consists of two masters with distributed tasks: The master class 1 performs open–loop and closed–loop control tasks, master class 2 is used for HMI functions.
Introduction Profiles In addition to the EN standard 50170, the PNO (PROFIBUS user organization) has defined the functionality of the individual field device types in a profile description. These profiles define minimum functional requirements and optional extensions. The device–internal ”device management” provides the configuration tool of the control system with all basic information necessary to locate the profile parameters.
Introduction The maximum number of devices that you can connect to a bus train depends on the current consumption and the application conditions. During operation in a safe zone, the couplers or links supply up to 400 mA to the bus. In zones subject to explosion hazard, intrinsic safety is only ensured if the maximum power fed into the bus does not exceed certain voltage and current values.

Design and Method of Operation Design and Method of Operation 2 This Section describes the mechanical and electrical design, the components of the instrument and the principal method of operation of the instrument. 2.1 Overview Introduction The SIPART PS2 electropneumatic positioner forms a closed-loop control system together with an actuator. The current position of the actuator is acquired via a servo-potentiometer and returned as actual value x.
Design and Method of Operation The actuator position can be output as 2–wire signal Jy = 4 to 20 mA using the Jy option module. The actuator can also be monitored for two programmable limit values. Limit value alarms are output via the alarm option module that can also monitor and signal the function of the positioner and the actuator. In automatic operation the system deviation is monitored as a function of the actuating time.

Design and Method of Operation Positioning pressure Connection Actuator type Y1 Closed Safety position after auxiliary power failure electrical pneumatic Closed Closed Open Open Open Y1 Closed On rotary actuators the counter–clockwise direction of rotation – looking at the actuating shaft of the valve – is defined as “open”.
Design and Method of Operation 2.2.4 Mounting kit The positioner can be mounted on nearly all common types of actuators using the appropriate mounting kit. 2.2.5 Purging air switchover The purging air changeover switch above the pneumatic terminal block (Fig. 2-5) on the valve manifold can be accessed when the housing is open. When the switch is in position IN the interior of the housing is purged with very small quantities of clean and dry instrument air.
Design and Method of Operation 2.3 Method of operation The electropneumatic positioner SIPART PS together with the pneumatic actuator forms a control loop in which the actual value x is the position of the actuator rod on linear actuators and the position of the actuator shaft on rotary actuators and the reference variable w is the actuating current of a controller or manual control station of between 0/4 and 20 mA. With devices with PROFIBUS PA, the command variable w is set digitally via a bus system.

The driver must be set to the value of the actuator travel or, if this value is not scaled, to the next largest scaled value. 4.INIT Initialization Automatic initialization is started when you select “Strt” and press the increment key (> 5 s). Initialization is displayed by “RUN 1” to “RUN 5” (see Fig. 3-22 to Fig. 3-24) as it progresses. 5.SDIR Setpoint direction (see Fig.
Operation 09.SL0 to 29.SL20 Setpoint turning points (see Fig. 4-9) Each setpoint turning point can be assigned a flow characteristic value at intervals of 5%. These points produce a polygon consisting of 20 straight lines which results in an image of the valve characteristic curve. Setpoint turning points can only be entered when 8.SFCT = FrEE. 33.YNRM = 33.YNRM = MPoS FLoW [%] [%] 100 YE = 96 % 100 90 8. SFCT = n1:25 90 80 70 60 80 70 60 8.SFCT = lin 50 50 40 8.
Operation 30.DEBA Dead zone of the controller when DEBA = AUto the dead zone is constantly adapted to the requirements of the control loop in automatic mode. If control oscillation is detected the dead band is increased step by step. Reverse adaptation is achieved using a time criterion. In other discrete settings the permanent value for the dead zone is used. 31.YA Start of manipulated variable limiting (see Fig. 4-8) and 32.YE End of manipulated variable limiting (see Fig. 4-8) With parameters 31.
