Betriebsanleitung D A L (Ex-Schutz relevanter Teil) für induktive Näherungssensoren gemäß der EU-Richtlinie 94/9/EG Anhang VIII (ATEX) Gruppe II, Gerätekategorie 3G Operating instructions GB IRL (Ex protection related part) for inductive proximity switches according to EU directive 94/9/EC Annex VIII (ATEX) group II, equipment category 3G Notice d'utilisation F B L (partie concernant la protection Ex) pour détecteurs de proximité inductifs selon la directive UE 94/9/CE annexe VIII (ATEX) groupe II, catégorie 3G Instrucciones de servicio E (parte relativa a la protección contra explosiones) para detectores de proximidad inductivos conforme a la Directiva 94/9/CE Anexo VIII (ATEX) de la UE grupo II, categoría de aparato 3G Libretto d'istruzioni I 704240/02 10/2007 (sezione riguardante la protezione antideflagrante) per sensori di posizione induttivi in conformità alla direttiva UE 94/9/CE appendice VIII (ATEX) gruppo II, categoria apparecchi 3G Driftinstruktion S (Ex-skydd relevant del) för induktiv beröringsfri givare enligt EU-riktlinjen 94/9/EG Bilaga VIII (ATEX) Grupp II, apparatkategori 3G ENGLISH GB IRL Remarks for safe use in hazardous areas Function and features • Use in hazardous areas according to the classification II 3G (group II, category 3, apparatus for gas atmosphere). Fulfils the requirements of the standard EN 60079-15: 2005. • Marking (see unit or technical data sheet) II 3G Ex nA II T6 X -10 °C ≤ Ta ≤ 50 °C • Permissible operating temperature of the application (proper usage) -10 °C ≤ Ta ≤ 50 °C Installation /Set-up The units should only be mounted, connected and put into service by qualified staff. The qualified staff must have knowledge of protection classes, regulations and provisions for apparatus in hazardous areas. Check whether the classification (see "Marking" above and marking on the unit) is suitable for the application. Installation remarks / Mounting • Adhere to the relevant national regulations and provisions as well as the relevant installation regulations. • Avoid electrostatic charging on plastic units and cables. • Avoid electrostatic charging, only clean the unit with a damp cloth. • To avoid electrostatic charging steps must be taken to ensure the equalisation of potential of metal parts (plug housing, fixing elements, protective housing, etc.). • Protect the unit and the cable efficiently against damage. • For the connections and the electrical technical data please see the unit marking or the technical data sheet. • To avoid soiling, do not remove the connector cover until attaching the mating connector. • Protect the unit (plastic parts) from UV light. 2 Special conditions for safe operation • The unit (1) must only be installed in conjunction with the supplied protective housing (2) and the supplied metal plate (3). 2 1 3 3 • The connectors must be tightened so that they cannot be disconnected without using a tool. Use ifm sockets with the order number EVC011 or EVC012. Secure the connector. Tighten the coupling nut with a tightening torque of approx. 1.2..1.5 Nm This tightening torque is ensured as follows: Hand-fasten the coupling nut (0.5...0.6 Nm). Then turn by another notch using a screwdriver across the flats 14. If you do not use ifm connectors, make sure that the nut cannot be loosened manually. • Connect the output (M12 socket) with angled M12 plugs, preferably ifm jumper E10817 (type A) or E70143 (type B) or E10844 (type C). Make sure that the nut cannot be loosened manually. • Do not disconnect the connector while live. • The housings are rated for a low mechanical risk and tested with an impact energy of 4 joules. • The sensing face is not designed for mechanical stress. Therefore the unit must only be operated with target pucks which exclude mechanical stress on the sensing face. Maintenance / repair The unit must not be modified nor can it be repaired. In case of a fault please contact the manufacturer. If you need the technical data sheet and the CE declaration of conformity please contact the manufacturer. Indicate the article number. 4
