APPENDIX 4

BA364E Two input Counter

The BA364E Counter is functionally identical to the
BA364G Counter described in the main sections of
this manual, but differs in mechanical construction,
certification and factory fitted options.

All BA364E Counters are fitted with:

A Green internally powered display backlight

Dual galvanically isolated alarms

An isolated 4/20mA current sink output

These are only available as factory fitted options for
the BA364G Counter.

A4.1 Mechanical construction

The BA364E is housed in a robust GRP IP66
enclosure with a separate terminal compartment.
Section A4.5 of this appendix describes the
enclosure and installation procedure.

A4.2 Certification

The BA364E has the same ATEX, IECEx and ETL
intrinsic safety certification as the BA364G, but the

BA364E does not have ATEX and IECEx dust
certification

The safety parameters and certification numbers
specified in this manual for the BA364G Counter also
apply to the BA364E Counter. Therefore all of the
systems described for the BA364G in the main
section of this manual may also be used for the
BA364E.

A4.3 Location

The BA364E Counter is housed in a robust IP66
glass

reinforced

polyester

(GRP)

enclosure

incorporating an armoured glass window and
stainless steel fittings.

It is suitable for exterior

mounting in most industrial installations, including
off-shore and waste water treatment sites. The
Counter should be positioned where the display is
not in continuous direct sunlight.

The field terminals and the two mounting holes are
located in a separate compartment with a sealed
cover allowing the instrument to be installed without
exposing the display assembly.

The enclosure is fitted with a bonding plate to ensure
electrical continuity between the three conduit / cable
entries.

A4.4 BA364E Accessories

A4.4.1 Units of measurement & instrument

identification.

The BA364E is fitted with a blank escutcheon around
the liquid crystal display.

This can be supplied

printed with any units of measurement and tag
information specified at the time of ordering.
Alternatively, the information may be added on-site
via an embossed strip, dry transfer or a permanent
marker.

To gain access to the escutcheon remove the
terminal cover by unscrewing the two 'A' screws
which will reveal two concealed 'D' screws.
Remove the push buttons by unscrewing the two 'C'
screws and un-plug the five way connector. Finally,
unscrew all four 'D' screws and carefully lift off the
front of the instrument.

The location of all the

screws is shown in Fig A4.1.

Add the required legend to the display escutcheon,
or stick a new pre-printed self-adhesive escutcheon,
which is available from BEKA associates, on top of
the existing escutcheon. Do not remove the original
escutcheon.

The BA364E can also be supplied with a blank or
custom laser engraved stainless steel plate secured
by two screws to the front of the instrument
enclosure. This plate can typically accommodate:

1 row of 9 alphanumeric characters 10mm high

or 1 row of 11 alphanumeric characters 7mm high

or 2 rows of 18 alphanumeric characters 5mm
high.

A4.4.2 Pipe mounting kits

The BA364E Counter is surface mounting, but may
be pipe mounted using the BA392D or the BA393
pipe mounting kit.
