Note To improve the interference immunity: Lay signal cables separately from cables with voltages > 60 V. Use cables with twisted wires. Avoid getting too close to large electrical systems or use shielded cables. Use shielded cable to guarantee the full specification according to PROFIBUS PA or FOUNDATION Fieldbus. Use only cable entries and covers that are approved for the relevant use. At an ambient temperature T 60 C, use heat-resistant cables approved for an ambient temperature of at least 20 K higher. Use cables with wires that have a maximum cross-sectional area of 2.5 mm 2. See also Connection diagrams (Page 23) Operating Instructions, 06/2010, A5E

20 Connecting 5.1 Safety information on connecting up Safety notes when connecting in hazardous areas WARNING Observe the degree of protection The device must be connected to the supply and signal circuits named in the certificate or on the nameplate. When installing the device in hazardous areas, use housings/connection heads with the degree of protection corresponding to the inspection certificate valid in your country. WARNING Electrical connection in hazardous areas The national directives and laws for hazardous areas valid in your country must be observed for electrical connection. In Germany these are, for example: The health and safety at work regulations The directive for "Installation of electrical systems in hazardous areas", DIN EN (previously VDE 0165,T1) The EC type examination certificate When a auxiliary power supply is needed, check whether the auxiliary power supply matches that given on the nameplate and with the inspection certificate valid in your country. CAUTION Limited range of use If the device has been operated outside the ambient conditions specified for potentially explosive atmospheres, you may no longer operate the device in potentially explosive atmospheres. Make sure to permanently mask all Ex markings on the nameplate. NOTICE Loss of type of protection "Intrinsic safety" If the transmitter is not operated with an intrinsically-safe power supply, the type of protection "Intrinsic safety" is no longer guaranteed and the intrinsically-safe approval may be revoked. Permanently erase, therefore, the irrelevant types of protection on the nameplate before commissioning to ensure that erroneous deployment is avoided. Note Be sure to observe the inspection certificates valid in your country. The input circuit is thus electrically isolated from the sensor circuit. The isolation does not satisfy the requirements for infallible electrical isolation in the sense of the intrinsic safety standard EN / IEC , but does withstand a test voltage of 500 V AC/1 minute. 20 Operating Instructions, 06/2010, A5E

32 Functions 8.2 Device address 8.2 Device address PROFIBUS PA Note Before operating two or more field devices, make sure that the device addresses are set on the bus. Assign each address only once, so that the addresses are allocated uniquely. The address range is from 1 to 125. From the warehouse, the -PA is set to the address 126. Normally in the PROFIBUS PA systems the masters are assigned the lower addresses. Begin the address assignment at FOUNDATION field bus Note The following points are necessary for the -FF to function properly: a unique node address; a physical device identifier for the fieldbus. The node address must be unique within the link (segment), while the physical device identifier must be unique within the entire network. When delivered, the -FF has a unique physical device identifier. The device identifier is a concatenation of the string "" and part of the serial number. The node address is set to "22". In the unit configuration, set the node address to a value that is unique within the link. To avoid address conflicts, the -FF automatically sets its address to one of the temporary standard addresses between 248 and 251 as soon as it recognizes another device with the same node address. 32 Operating Instructions, 06/2010, A5E

55 Glossary Analog One variable, e.g. voltage which is infinitely adjustable, in contrast to "Digital". ATEX ATEX is an abbreviation of the French term "Atmosphère explosible" (potentially explosive atmosphere). ATEX stands for both EC directives in the area of explosion protection: ATEX product directive 94/9/EC and ATEX operating directive 1999/92/EC. Auxiliary power supply Auxiliary power supply is an electrical supply voltage or reference voltage, such as many electrical circuits require in addition to the standard power supply. The auxiliary power supply is specially stabilized, has a specific level and polarity and/or has other properties that are important for correct operation of circuit components. Auxiliary voltage Auxiliary power supply CE Communautés Européenes: European communities Dangerous failure Failure with the potential to bring the safety-instrumented system into a dangerous or nonfunctional status. DC Direct Current: Direct Current Digital Representation of a variable, e.g. time, in the form of characters or numbers. In its digital representation, this variable can be changed only in pre-defined steps. In contrast to "Analog". DIN Deutsches Institut für Normung e. V. - German institute for standardization Operating Instructions, 06/2010, A5E

56 Glossary EC low-voltage directive The EC low voltage directive applies to electrical resources with rated voltages of: AC from 50 V to 1000 V; DC from 75 V to 1500 V. EEPROM Electrically Erasable Programmable Read Only Memory EEPROMs are often used where individual bytes of data (e.g. configuration data or runtime meters) change over time and must be stored safely in the event of a mains power failure. EMC Electromagnetic compatibility Definition in accordance with EMC law: EMC is the capability of a device to operate satisfactorily in an electromagnetic environment without itself emitting electromagnetic signals which interfere with other devices in that environment. EN Europäische Norm - European standard EU European Community Fail-safe The capability of a control to maintain the safe state of the controlled device, e.g. machine, process, or to bring the device to a safe state even when faults/failures occur. Failure/Fault Failure: A resource is no longer capable of executing a required function. Fault: Undesired state of a resource indicated by the incapability of executing a required function. Fault Failure/Fault 56 Operating Instructions, 06/2010, A5E

57 Glossary Fault tolerance Fault tolerance N means that a device can execute the intended task even when N faults exist. The device fails to execute the intended function in case of N+1 faults. Final controlling element Converter that converts electrical signals into mechanical or other non-electrical variables. Firmware Firmware (FW) is software which is embedded in a chip in electronic devices unlike software that is stored on hard drives, CD ROMs, or other media. These days, firmware is mostly stored in a flash memory or EEPROM. Firmware usually contains the elementary functions for controlling the device, as well as input and output routines. Frequency shift keying Frequency shift keying in a simple form of modulation in which the digital values 0 and 1 are represented by two different frequencies. Frequency Shift Keying (FSK) Frequency shift keying HART HART (Highway Addressable Remote Transducer) is a standardized, widely used communications system used to structure industrial fieldbuses. The communications system provides digital communications for multiple participants (field devices) via a common databus. HART is based especially on the equally widely used 4/20 ma standard for the transfer of analog sensor signals. The cabling from existing older systems can be used directly and both systems operated in parallel. HART specifies several protocol levels in the OSI model. It facilitates the transfer of process and diagnostics data and control signals between field devices and high-level control systems. Standardized parameter sets can be used for the manufacture-independent operation of all HART devices. Typical applications include transmitters for measuring mechanical and electrical dimensions. IP International Protection = international degree of protection Operating Instructions, 06/2010, A5E

58 Glossary Microcontroller Microcontrollers (also written µcontrollers, µc, MCU) are single-chip computer systems which have virtually all their components - such as main processor, program memory, working memory and the input/output interfaces - accommodated on a single chip. Non-volatile memory EEPROM Risk The combination of probability of a damage occurring and its magnitude. RS -232 RS: Recommended Standard A recognized industry standard for serial data transfer. For cable lengths shorter than 15 m. No differential evaluation. Transmit and receive on different lines. Safety function Defined function executed by a safety-instrumented system with the objective of achieving or maintaining a safe system status taking into account a defined dangerous occurrence. Example: Limit pressure monitoring Safety Instrumented Function SIF Safety Integrity Level SIL Safety-instrumented system A safety-instrumented system executes the safety functions that are required to achieve or maintain a safe status in a system. It consists of a sensor, logic unit/control system and final controlling element. Example: A safety-instrumented system is made up of a pressure transmitter, a limit signal sensor and a control valve. Sensor Converter that converts mechanical or other non-electrical variables into electrical signals. 58 Operating Instructions, 06/2010, A5E
