    The FD67 bus system combines the decentralized signals of the I/O level and provides this information to the Fieldbus network (Profibus DP, DeviceNet or CANopen). The central unit is the bus node, which interconnects the VS18/VS26 FD67 valve islands and/or the FD67 bus modules and the standard Fieldbus (Profibus DP, DeviceNet or CANopen).

    Precipitation, contamination, and aged or worn gaskets can cause failures. Gaskets must be included to ensure the protection class. Damaged parts must be replaced with original spare parts from Norgren. VS2672926-KG00E_05/07 Page 92/97...

  • Page 93: Atex Conformity

    Use conditions: Note: 1. The valve islands VS18 and VS26 conform to the Directive 94/9/EC (ATEX 95) Annex I „equipment of the equipment group II category 3G“, which are potentially explosive through inflammable material in range of temperature class T1 to T4 in zone 2 as well as in the explosions groups IIA, IIB and IIC according to Directive 99/92/EC (ATEX 137) and can be used correspondingly.

  • Page 94: Specific Conditions

    The valve island must be used with plugs and cables, which have a conformity evaluation according to Directive 94/9/EC (ATEX 95) Annex VIII as well as protection class IP65. 1. Recommendation: Use plugs or cables from Norgren, which are certified according to Directive 94/9/EC (ATEX 95) Annex VIII.
