Description The sensor, logic unit/control system and final controlling element combine to form a safetyinstrumented system, which executes a safety function.
Functional safety 8.1 General safety notes Functioning of the system as shown in the example The transmitter generates a process-specific analog signal. The downstream control system monitors this signal to ensure that it does not fall below or exceed a set limit value. In case of a fault, the control system generates a failure signal of < 3.6 mA or > 22 mA for the connected positioner, which switches the associated valve to the specified safety position. 8.1.
Functional safety 8.2 Device-specific safety notes The following table shows the achievable Safety Integrity Level (SIL) for the entire safetyinstrumented system for type B subsystems depending on the safe failure fraction (SFF) and the hardware fault tolerance (HFT). Type B subsystems include analog transmitters and shut-off valves without complex components, e.g. microprocessors (also see IEC 61508, Section 2).
Functional safety 8.2 Device-specific safety notes 8.2.2 Safety function Safety function on positioner The safety function on the SIPART PS2 positioner is the depressurizing of the connected valve actuator. The built-in spring brings the valve to the required safety position. Depending on the direction of action of this spring, the valve is completely opened or closed. This function is referred to as "tight closing" in the device documentation.
Functional safety 8.2 Device-specific safety notes 8.2.3 Settings After assembly and commissioning, the following parameter settings should be made for the safety function: Safety parameters Parameter name Function Set parameter value Meaning 2.YAGL Rated angle of rotation of the feedback shaft 33° or 90° to match the setting for the transmission ratio selector Adaptation to the mechanically set range of stroke / rotation angle 6.SCUR Current range of setpoint 4 MA 4...20 mA 7.
Functional safety 8.2 Device-specific safety notes Checking the safety function To check that the safety configuration is correct, apply a set current of 3.6 mA. In this condition, the valve actuator must bring the valve to the intended safety position. 8.2.4 Behavior in case of faults Repairs Defective devices should be sent in to the repair department with details of the fault and the cause. When ordering replacement devices, please specify the serial number of the original device.

Appendix A.3 Test report (extract) Management summary This report summarizes the results of the hardware assessment with proven-in-use consideration according to IEC 61508 / IEC 61511 carried out on the Electro-pneumatic Positioner SIPART PS2 with software version C4 and C5. Table 1 gives an overview of the different configurations that belong to the considered Electro-pneumatic Positioner SIPART PS2. The hardware assessment consists of a Failure Modes, Effects and Diagnostics Analysis (FMEDA).
Appendix A.3 Test report (extract) As the Electro-pneumatic Positioner SIPART PS2 is supposed to be a proven-in-use device, an assessment of the hardware with additional proven-in-use demonstration for the device and its software was carried out. The proven-in-use investigation was based on field return data collected and analyzed by SIEMENS AG, A&D PI TQ2. This data cannot cover the process connection. The proven-in-use justification for the process connection still needs to be done by the end-user.
Appendix A.3 Test report (extract) The assessment has shown that the Electro-pneumatic Positioner SIPART PS2 when used as a single-acting shut-down module ("tight closing bottom") has a PF D AV G within the allowed range for SIL 2 according to table 2 of IEC 61508-1 and table 3.1 of ANSI/ISA– 84.01–1996 and a Safe Failure Fraction (SFF) of more than 84%.

Glossary Analog A signal type which represents data using continuously varying, measurable and physical quantities, e.g. current or voltage. Opposite to digital. The range between 4 and 20 mA is often used to transfer analog signals. Analog-to-digital converter An analog-to-digital converter is an interface between the analog environment and the digitally working computers. Only then can the computers be used for measurement and control tasks.
Glossary Configuration See parameterization. Cornerstone Management software for process instrumentation. Dangerous failure Failure with the potential to switch a safety-instrumented system to a hazardous or nonfunctioning safety status. Decrement From the Latin word decrementare, decrease. Decrement is the defined amount of change when decreasing a variable(s) gradually. In informatics, it is referred to as the stepwise decrease in a numeric value.→Increment.
Glossary Digital Representation of a variable in the form of characters or numbers. The functional course of an originally changeable analog variable is simulated in predefined stages. Predefined values are assigned to these stages. Opposite to "analog". EEPROM EEPROM (Electrically Erasable Programmable Read-Only Memory; literally: elektrisch löschbarer, programmierbarer Nur-Lese-Speicher in German) is a non-volatile electronic memory.
Glossary Final controlling element Converter that converts electric signals into mechanical or other non-electric variables. Firmware Firmware (FW) is the software embedded in a chip in electronic devices. It is not like software that is stored on hard disks, CD-ROMs or other mediums. These days, the firmware is mostly stored in a flash memory or an EEPROM. Firmware is software in the hardware, and is thus an intermediate between the software and the hardware. Firmware is normally model-specific.
Glossary HART communicator Connection with a two-wire line is directly established for the parameterization with the HART communicator. For the parameterization with a laptop or a PC, a HART modem is connected in between. Increment From the Latin word incrementare, increase. Increment is the defined amount of change when increasing a variable(s) gradually. In informatics, it is referred to as the stepwise increase in a numeric value.→Decrement. Initialization Setting the most important basic parameters.
Glossary NEMA 4x The same protection like NEMA 4. Additional protection of the enclosure from corrosion. Parameterization During parameterization, individual parameter settings are specifically changed to adjust the positioner as per the actuator or other requirements. Parameterization is carried out after the complete commissioning of the positioner. Piezoelectric effect Name of a physical phenomenon.
Glossary layer of the reference model. Transport protocols are used for the lower four layers of the reference mode and higher protocols are used for control, data provision and application. Safety function Defined function executed by a safety-instrumented system with the objective of attaining or maintaining a safe status of the system by taking a defined hazardous incident into account.
Glossary Zone 1 Area in which potentially explosive gaseous atmospheres build up occasionally during the normal operation of a device. Zone 2 Area in which potentially explosive gaseous atmospheres normally never build up or build up for a short while during the normal operation of a device. Zone 22 Zone 22 is an area in which a potentially explosive gaseous atmosphere in the form of a cloud of combustible dust in air never develops or develops only for a short while during normal operation.
