E2S BExBG21D Instruction Manual

1) Introduction
The BExBG21D is a flameproof beacon certified to meet the
requirements of the ATEX directive 94/9/EC and the IECEx
scheme. The beacon produces synchronised visual warning
signals and can be used in hazardous areas where
potentially flammable gas and dust atmospheres may be
present. The BExBG21D has can be used in Zone 1 and
Zone 2 areas with gases in groups IIA, IIB and IIC and
Temperature Classifications of T1, T2, T3 and T4 in an
ambient temperature up to +55ºC. The beacon can also be
used at an ambient temperature up to +70ºC with a
temperature classification of T3. The units can be used in
Zone 21 and Zone 22 areas for combustible dusts and have
an IP rating of IP 67 and a surface temperature rating of
T135ºC if the upper ambient temperature is restricted to
+55ºC or T200ºC with an the upper ambient temperature of
+70ºC. The BExBG21D beacon has two xenon tubes and
can produce three different flash patterns.
2) Marking

Installation Requirements
The beacon must be installed in accordance with the latest
issues of the relevant parts of the BS EN 60079
specifications or the equivalent IEC specifications –
Selection, Installation
apparatus for use in potentially explosive atmospheres (other
than mining applications or explosive processing and
manufacture):-
EN60079-14:2008
IEC60079-14:2007 (Ed4)
EN60079-10:2003
IEC60079-10:2008 (Ed1)
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried
out by a competent electrical engineer who has the
necessary training.
5)
Zones, Gas Group, Category, IP Rating and
Temperature Classification
The BExBG21D beacon has been certified Ex d IIC T3 Ta –
50ºC to +70ºC and Ex d IIC T4 Ta –50ºC to +55ºC for gas
and Ex tD IP67 T200ºC based on max Ta +70ºC and T135ºC
based on max Ta +55ºC for dust. This means that the units
can be installed in locations with the following conditions:-
Area Classification Gas:
Zone 1 Explosive gas air mixture likely to occur in
normal operation.
Zone 2 Explosive gas air mixture not likely to occur,
and if it does, it will only exist for a short time.
Gas Groupings:
Group IIA
Group IIB
Group IIC
