Please contact Pepperl+Fuchs for information about supported NAMUR vibrating
forks. The sensors listed in the datasheet, as well as mechanical switches could be in-
stalled as conventional binary control circuits.
Mounting and Installation
When using intrinsically safe devices in accordance with IEC/EN 60079-11, follow the
EC-type-examination certificate and the national regulations for installations. Refe-
rence should be made to IEC/EN 60079-14 for the interconnection of the intrinsically
safe circuits. In the Federal Republic of Germany reference should also be made to the
"National foreword" to DIN 60079-14/VDE 0165 Part 1.
The Sensor Interface FD0-BI-Ex12.**** is designed for use in potentially explosive at-
mospheres. The respective maximum values of the field devices and of the Valve
Coupler must be considered in the sense of explosion protection (demonstration of in-
trinsic safety) when interconnecting the intrinsically safe field devices (auxiliary valves,
sensors, vibrating forks, etc.) with the intrinsically safe circuits of the Valve Coupler.
The fieldbus connection is a certified, intrinsically safe circuit, in accordance with the
FISCO and the Entity model.
When interconnected according to the FISCO model, all the field devices and associa-
ted apparatus (fieldbus repeaters) connected to this segment must be certified in ac-
cordance with the FISCO model.
General
Mounting, installation, commissioning, operation, maintenance and disassembly of
any devices may only be carried out by trained, qualified personnel. The instruction
manual must be read and understood.
If devices have already been operated in general electrical systems, they may subse-
quently no longer be installed in electrical systems used in combination with hazardous
areas.
In case the Valve Coupler has been operated in the type of protection "Ex ic", it must
not be operated in the type of protection "Ex ia" or "Ex ib" afterwards.
The datasheet containing the electrical data from the EC-type-examination certificate
respectively the IECEx Certificate of Conformity and additional technical information is
effectively a part of this operating instruction.
Subject to reasonable modifications due to technical advances.
