1. DESCRIPTION
The BA444DF-P fieldbus indicator is an intrinsically
safe, PROFIBUS PA instrument, that may be
configured as a fieldbus node or as a fieldbus
listener. It can display up to eight fieldbus process
variables on a five digit LCD and a 31 segment
analogue bargraph. The instrument is bus
powered so no additional power supply is required
and has PROFIBUS PA User Organisation
approval, certificate Z01505.
Fieldbus node configuration may be performed by
either a User PRM data download or by a DPV1
configurator, and if required, the instrument
address may be entered via the front panel push
buttons.
When configured as a fieldbus listener, the
BA444DF-P is not visible to the fieldbus host and
can only be configured using the push buttons on
the front of the instrument.
Housed in a robust IP66 glass reinforced polyester
(GRP) enclosure with a toughened glass window,
the BA444DF-P 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 BA444DF-P is
available with intrinsic safety and nonincendive FM
and cFM Approval – see Appendix 2.
For international applications, all versions of the
BA444DF-P PROFIBUS PA 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 ‘-P’ order
code suffix also indicates the protocol but is not
shown on the instrument certification label.
There is an alternative version of the fieldbus
display, order code BA444DF-P for use on
FOUNDATION™ fieldbus networks.
1.1
Documentation
This instruction manual describes ATEX system
design and installation of the BA444DF-P
PROFIBUS PA indicator.
System design information for non-ATEX and dust
approvals is shown in appendices to this manual.
2. OPERATION
The BA444DF-P indicator can display up to eight
pre-configured PROFIBUS PA process variables
designated in-1 to in-8. The operator can select
which variable is displayed using the
▼
or
▲
push
buttons which scroll the display through the eight
inputs. A numeric annunciator on the left hand
side of the display shows which of the eight inputs
is currently being displayed.
2.1 Error messages
‘no ConF’
No inputs have been
configured or are enabled.
‘no dAtA’
No data is being received
with the current configuration.
3. INTRINSIC SAFETY CERTIFICATION
3.1 ATEX certificate
The BA444DF-P 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 BA444DF-P 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 94/9/EC. The BA444DF-P 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.
