1. DESCRIPTION
The
BA414DF-F
Fieldbus
Indicator
is
an
intrinsically
safe,
FOUNDATION™
fieldbus
instrument compliant with ITK 6.3 that can display
one fieldbus process variable on a five digit LCD
and 31 segment analogue bargraph.
The
instrument is bus powered so no additional power
supply is required.

FOUNDATION™ fieldbus Input Selector (1 x IS)
The Device Description files may be downloaded
from The FieldComm or the BEKA associates web
sites.
Housed in a robust IP66 glass reinforced polyester
(GRP) enclosure with a toughened glass window,
the BA414DF-F is surface mounting, or may be
pipe mounted using one of the accessory kits.
The instrument has been certified intrinsically safe
by European Notified Body Intertek Testing and
Certification Ltd (ITS) for use in explosive gas and
combustible dust atmospheres.
ATEX dust
certification is an option – see Appendix 1.
For use in the USA and Canada, the BA414DF-F is
available
with
optional
intrinsic
safety
and
nonincendive FM and cFM Approval – see
Appendix 2.
For international applications, all versions of the
BA414DF-F fieldbus indicator have IECEx intrinsic
safety approval allowing installation in explosive
gas atmospheres.
IECEx dust certification is
available as an option – see Appendix 3.
The instrument’s communication protocol is shown
on a label inside the terminal cover. The ‘-F’ order
code suffix also indicates the protocol but is not
shown on the instrument certification label.
1.1
Documentation
This instruction manual describes ATEX system
design and installation of the BA414DF-F Fieldbus
Indicator.
For commissioning information please
refer to:
FOUNDATION™ fieldbus
Fieldbus Interface Guide
for
Fieldbus Displays and
Fieldbus Indicators
which can be downloaded from the BEKA website

System design information for non-ATEX and dust
approvals is shown in appendices to this manual.
2. INTRINSIC SAFETY CERTIFICATION
2.1 ATEX certificate
The BA414DF-F has been issued with an EC-Type
Examination Certificate ITS06ATEX25313X by
Notified Body Intertek Testing and Certification Ltd
(ITS) confirming compliance with harmonised
European standards.
The BA414DF-F fieldbus
indicator has Ex ia FISCO and entity parameter
certification plus Ex ic entity parameter approval
for use in Zone 2 with higher supply voltages.
The EC-Type Examination certificate has been
used to confirm compliance with the European
ATEX Directive 2014/34/EU.
The BA414DF-F
carries the Community Mark and, subject to local
codes of practice, may be installed in any of the
European
Economic
Area
(EEA)
member
countries. ATEX certificates are also acceptable
for installations in Switzerland.
This manual describes ATEX installations in
explosive gas atmospheres which conform with
EN
60079:14
Electrical
installation
design,
selection and erection.
When designing systems
for installation outside the UK, the local Code of
Practice should be consulted.
For use in the presence of combustible dust,
please refer to Appendix 1.
2.2 Ex ia Zones, gas groups and T rating
The BA414DF-F has Group II Category 1G Ex ia
IIC T4 Ga –40
≤
Ta
≤
70
o
C FISCO and entity
parameter approval.
When connected to a
suitable certified system the BA414DF-F may be
installed in:
Zone 0
explosive gas air mixture
continuously present.
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 will
only exist for a short time.
Be used with gases in groups:
Group A propane
Group B ethylene
Group C hydrogen
In gases which may be used with equipment
having a temperature classification of:
T1
450ºC
T2
300ºC
T3
200ºC
T4
135ºC
At an ambient temperature between –40 and
+70ºC
