E2S BExBG05D Instruction Manual

1) Introduction
The BExBG05D is a second generation flameproof beacon
which is certified to the European Standards EN 50014:
1992, EN 50018: 1994, the Combustible Dust standard EN
50281-1-1: 1999 and meets the requirements of the ATEX
directive 94/9/EC. 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 BExBG05D has an output level of 5 joules and
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, T4 and T5. The unit can also be used in a
temperature classification
temperature is restricted to +40ºC. The unit can be used in
Zone 21 and Zone 22 areas for combustible dusts and has
an IP rating of IP 67 and a surface temperature rating of
T100ºC or T85ºC if the upper ambient temperature is
restricted to +40ºC.

The beacons have an EC Type examination certificate issued
by KEMA and have been approved to the following
standards:-
EN 50014 : 1992 + prA1
EN 50018 : 1994 + prA1 + prA2 + prA3
EN 50281-1-1 : 1999
4)
Installation Requirements
The beacons 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 and
apparatus for use in potentially explosive atmospheres (other
than mining applications or explosive processing and
manufacture):-
BS EN 60079-14 : 1997
BS EN 60079-10 : 1996
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 BExBG05D beacons have been certified EEx d IIC T5
(Tamb. –50 to +55ºC) and EEx d IIC T6 (Tamb. –50 to
+40ºC) for gas and IP67 T100ºC Ta < +55ºC and T85ºC Ta
< +40ºC 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
Temperature Classification:
T1 400
T2 300
T3 200
T4 135
T5 100
T6 85
