Design and Functional Principle Design and Method of Operation 2 The following chapter describes the mechanical and electrical design, the instrument components and method of operation of the positioner. 2.1 Overview Introduction The electropneumatic positioner forms a control system in connection with an actuator. The current position of the actuator is detected by a servo potentiometer and fed back as actual value x. The setpoint and actual value are output simultaneously on the display.
Design and Functional Principle spond even when the power supply fails or the electronics are defective. The actuator can also be blocked or driven to its final positions depending on the configuration for example by an external event via a digital input (DI2) on the alarm module. If you require electrically independent limit value messages from the standard controller, you will have to use the SIA module with the slot initiators instead of the alarm module.

Design and Functional Principle 2.3.3 Pneumatic Connections The pneumatic connections are on the right hand side of the positioner (figure 2-4 and figure 2-5).
Design and Functional Principle The exhaust air output E can be provided for supplying dry instrument air to the tapping chamber and spring chamber to prevent corrosion. Figure 2-6, page 21 shows the pneumatic connection variants for the different actuator types, the positioning action and the safety position after power failure.
Design and Functional Principle Positioning pressure Connection Actuator type Y1 Closed Safety position after power failure electrical pneumatic Closed Closed Open Open Open In part-turn actuators the direction of rotation counterclockwise looking onto the actuating shaft of the valve is usually defined as “Open”.
Design and Functional Principle 2.3.4 Mounting Kit The positioner can be mounted on almost all actuators with the appropriate mounting kit. 2.3.5 Purge air switching (not in the explosion proof version) The purge air switch is accessible above the pneumatic terminal strip with the housing open (figure 2-7). In the IN position the inside of the housing is purged with very small amounts of clean, dry instrument air. In the OUT position the purge air is fed directly to the outside air.
Design and Functional Principle 2.4 Method of Operation The electropneumatic positioner SIPART PS2 forms a control circuit with the pneumatic actuator in which the actual value x is the position of the actuator bar in linear actuators or the position of the actuator shaft in part-turn actuators and the command variable w is the actuating current of a controller or a manual control station of 4 to 20 mA.
Design and Functional Principle Figure 2-10, page 25 shows the block diagrams for single- and doubleacting actuators with the linear actuator as an example. . NOTE The exhaust air valve is always open when there is no current.

Operation The following configuration block diagram shows the effects of the parameters.
Operation Normally adjustment of the first three following parameters is completely sufficient to enable a positioner to be operated by an actuator. If you wish to become familiar with all details of the positioner, try out incrementally the effects of the remaining parameters by selective trials. . NOTE In particular if the positioner has previously been operated using a different actuator, it must always be reinitialized in order to restore the factory settings.
Operation S YFCT = ncSLL This must be adjusted if an NCS is to be connected to a linear actuator with the position converted by an arm into a part--turn movement. .

Operation . NOTE If the control function to close tightly is activated, for parameter “49. LIM” the monitoring of the control deviation in each overrun direction (YCDO: < 0 %, YCUP: > 100 %) is disabled. This function is particularly useful for valves with a soft seating. For long term monitoring of the end-stop positions, we recommend activating the parameters “52. ZERO” and “53. OPEN”. Value for tight closing, bottom and Value for tight closing, top 40.YCDO 41.YCUP . NOTE “40.
Operation With activated digital input the piezo-valves are blocked and the actuator remains in the last position. Leakage messages can then be executed without initialization function. S BIN1 oder BIN2 = PSt oder --PSt Depending on settings, a partial stroke test can be initiated via binary input 1 or 2 by actuating an opener or closer.
Operation . NOTE If you have activated the extended diagnostics (parameter 51.XDIAG) with On2 or On3, the alarms cannot be output via the alarm unit. However, the message is possible via HART communication at any time. 45.A1 46.A2 Response threshold alarm 1 and Response threshold alarm 2 The alarm thresholds are related to the mechanical path (MPOS-scale). 47. FCT Function of the fault message output The fault message output serves as a group message for following faults: S Control error (e.g.
Operation Monitoring time for setting the fault messages 48. TIM The set value(s) is/are for the specification of the time, within which the positioner must have reached a compensated state. The corresponding response threshold is preset with “49. LIM”. If the set time is exceeded, the fault message output is set. . NOTE If the tight closing function is activated, for parameter “49. LIM”, the monitoring of the control deviation in each overrun direction (YCDO: < 0 %, YCUP: > 100 %) is deactivated.
Operation 51.XDIAG Activation of the extended diagnostics The extended diagnostics is deactivated at the factory, parameter 51 is therefore at “OFF”. There are three operating modes for activating the extended diagnostics: S On1: The extended diagnostics is activated and the threshold 3 error messages are also output via the fault message output.
Operation A. PST Partial stroke test This parameter activates the partial stroke test for the cyclic or manual partial stroke test of Up/Down and modulating valves. The partial stroke test can be triggered via keyboard, a binary input or the HART communication. A1.STPOS Start position The start position of the partial stroke test is specified here within the range of 0.0 to 100.0%. A2.STTOL Start tolerance The start tolerance in relation to the start position is specified here in the range of 0.
Operation A6.PSTIN Partial stroke test reference step time (PSTIN = Partial Stroke Test Initialization) Measurement of the reference step time for the partial stroke test. After the initialization of the device, the calculated (C = calculated) average actuating time of the control valve is displayed in seconds in the form: C ###.#. This time can be used as reference step time, however it is only a rough guide value.
Operation b. DEVI General control valve malfunction This parameter activates the dynamic monitoring of the control valve reaction. To do this, the actual position sequence is compared to the guide value and the expected position sequence, which allows conclusions with regard to the correct operational behavior of the control valve. When the parameter is activated, the submenu for the general control valve malfunctions from b1 to b5 opens. The function can be configured there. b1.
Operation C. LEAK Pneumatic leakage This parameter is used to activate the function for the detection of a pneumatic leakage. To do so, the changes of position and the internally used controller output are recorded and filtered, depending on the direction. The filter result provides a coefficient that allows the detection of any leakage. Note that the detection of a leak can only provided clear results for spring-loaded actuators. C1.
Operation d. STIC Slipstick effect This parameter is used to activate the function for the detection of a slipstick effect. The device tries to detect sudden changes of the valve position that indicate excess slipstick. If the device detects a slipstick, the filtered step is saved as slipstick value. When the valve moves normally again (without detection of a slipstick), the slipstick value is reduced slowly.
Operation E. DEBA Dead zone monitoring This parameter activates the monitoring of the dead zone adaptation. Prerequisite for the function is the setting of parameter “34.DEBA” = Auto. E1.LEVL3 Threshold for the monitoring of the dead zone adaptation. This value (%) can be used for the automatic adaptation of the dead zone. If the dead zone exceeds the set value, the threshold 3 error message is triggered. The three-level error message is not implemented for dead zone monitoring. F.
Operation G. OPEN Shifting the upper stop This function is for detecting when the upper stop has changed its value compared to the value during initialization by more than the specified tolerance value. Monitoring is only possible if the valve is within the tight closing function. The activation of the “top tight closing function” (para“meter “39.YCLS”) is therefore prerequisite. G1.LEVL1 Threshold 1 First threshold for monitoring the upper limit stop.
Operation H. TMIN Monitoring of the lower temperature limit The current temperature in the positioner housing is measured by a sensor on the electronic circuit board. This parameter is for the three-level monitoring of the lower temperature limit. H1.TUNIT Temperature unit The temperature unit can be switched over by pressing the Greater Than or Smaller Than button between °C and °F. Another way of switching over is the J1.TUNIT parameter for monitoring the upper temperature limit.
Operation J. TMAX Monitoring of the upper temperature limit The current temperature in the positioner housing is measured by a sensor on the electronic circuit board. This parameter is for the three-level monitoring of the upper temperature limit. J1.TUNIT Temperature unit The temperature unit can be switched over by pressing the Greater Than or Smaller Than button between °C and °F. Another way of switching over is the H1.TUNIT parameter for monitoring the lower temperature limit.
Operation L. STRK Monitoring of the displacement integral This parameter activates the monitoring of the displacement integral. This function allows the preventive maintenance of the control valve, also see chapter 4.5 “Diagnosics”, page 122. L1.LIMIT Limit for the number of strokes Input of the limit for the number of strokes. The parameter can be used depending on the requirement profile of the user.
Operation O. DCHG Monitoring of the changes of direction This parameter activates the monitoring of the changes of direction. This function allows the preventive maintenance of the control valve, also see chapter 4.5 “Diagnosics”, page 122. O1.LIMIT Limit for the changes of direction Input of the limit for the number of changes of direction.

Operation 11 PST Monitoring of the partial stroke test The measured step time of the last partial stroke test is displayed here. A partial stroke test can be triggered manually by pressing the Greater Than button, or a partial stroke test that is just being performed can be interrupted. The following states are shown in the display: S OFF The partial stroke test function is deactivated in the configuration menu.
Operation 13 NXPST Time until the next partial stroke test The time until the next partial stroke test is displayed here (in days). Conditions are that the partial stroke test is deactivated in the configuration menu and a test interval is set. If one of these two conditions is not fulfilled “OFF” appears in the display. 14 DEVI General control valve malfunction This value provides information on the current dynamically determined deviation from the model behavior.
Operation 19 PAVG Average position value The comparison average calculated last is displayed here. There are also the following status messages: S OFF The basic function is deactivated in the configuration menu. S IdLE (inactive) The function has not been started yet. S rEF (reference average is calculated) The function was started and the reference interval is currently active. S COMP (comparison average is calculated) The function was started and the comparative interval is currently active.
Operation Short step zone up and Short step zone down 26 SSUP 27 SSDN The short step zone is the range of the controller, in which pulseshaped excitation signals are output. The pulse length is proportional to the control deviation. If the control deviation is not within the short step zone, then the valves are activated in permanent contact. These two parameters can be set for special applications (see chapter 4.7, page 143). Current temperature 28 TEMP Current temperature in the positioner housing.
Operation Save maintenance data 42 STORE for at least 5 seconds triggers a Pressing the increment button memory function. In doing so, the diagnostic data 7 to 18 is saved in a non--volatile memory as the “data of the last maintenance”. This diagnostic data consists of selected values that, when changed, can provide information on the mechanical wear of the valve. Normally, this function is operated via PDM, menu item: Device!Save maintenance info.
Operation 4.5.3 Online diagnosis While the positioner is in operation, some important values and parameters are monitored on a continuous basis. In “Configuration” mode, you can configure this monitoring in such a way that the fault message output is activated when a certain event occurs, such as e.g. when a limit is exceeded.

Operation 4 5 Stroke number monitoring Monitoring of the number of changes of direction The two values, number of strokes and number of changes of direction, are compared to the threshold values on a continuous basis. These values result from the parameters “L1.LIMIT” to “L4.FACT3” and “O1.LIMIT” to “O4.FACT3”. If they are exceeded, depending on the operating mode of the extended diagnostics, the fault message output reacts, and possibly also the alarm outputs.
Operation 9 Partial stroke test exceeds reference step time This error message appears on the one hand if a manual or cyclic partial stroke test is triggered and the test cannot be started because the valve is not within the start tolerance range. The error message also appears if one of the three thresholds of the partial stroke test that are a result of the reference step time (A6.PSTIN) times factors (A7.FACT1 to A9.FACT3) is violated.
