1. DESCRIPTION
The
BA614DF-F
Fieldbus
Indicator
is
a
FOUNDATION™ fieldbus instrument 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.

The Device Description files may be downloaded
from The Fieldbus Foundation or the BEKA
associates web site at www.beka.co.uk.
Housed in a robust IP66 glass reinforced polyester
(GRP) enclosure with a toughened glass window,
the BA614DF-F is surface mounting, or may be
pipe mounted using one of the accessory kits.
1.1 Documentation
This instruction manual describes system design
and installation of the BA614DF-F Fieldbus
Indicator. For commissioning information please
refer to:
FOUNDATION™ fieldbus
Fieldbus Interface Guide
for
Fieldbus Displays and
Fieldbus Indicators
which can be requested via the BEKA web site at
www.beka.co.uk
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 identification label.
2. SYSTEM DESIGN
The BA614DF-F Indicator is powered and
communicates via the fieldbus which is connected
to non-polarised terminals 1 and 2. As shown in
Fig 1 the instrument may be connected to any
fieldbus segment which can supply the additional
13mA required to power the instrument.

3. INSTALLATION
3.1 Location
The BA614DF-F Fieldbus Indicator is housed in a
robust IP66 glass reinforced polyester (GRP)
enclosure incorporating a toughened glass window
and stainless steel fittings. It is suitable for exterior
mounting in most industrial environments, including
offshore and wastewater treatment installations.
Please consult BEKA associates if high vibration is
anticipated.
The BA614DF-F enclosure is surface mounting.
Accessory kits described in sections 5.3 of this
manual enable the instrument to be mounted onto
a vertical or horizontal pipe.
The field terminals and the two enclosure mounting
holes are located in a separate compartment with a
sealed cover allowing the instrument to be installed
without exposing the display assembly.
The BA614DF-F earth terminal is connected to the
carbon loaded GRP enclosure. If this enclosure is
not bolted to an earthed post or structure, the earth
terminal should be connected to a local earth.
The BA614DF-F enclosure is supplied with a
bonding plate to ensure electrical continuity
between the three conduit / cable entries.
