1. DESCRIPTION
The BA334G is a eld mounting intrinsically safe, one input
Rate Totaliser which will function with a wide variety of
sensors. The instrument can display rate of ow and total
ow in the same or dierent engineering units.
This abbreviated instruction sheet is intended to assist with
installation, a comprehensive instruction manual describing
safety certication, system design and conguration may be
downloaded from the BEKA website or may be requested
from the BEKA sales oce.
The BA334G Rate Totaliser has IECEx, ATEX, UKEX, ETL
and cETL intrinsic safety certication for use in ammable gas
and dust atmospheres. The certication information label,
which is located on the top of the instrument assembly, shows
the certication numbers and codes. Other certications may
be shown. Copies of certicates may be downloaded from
the BEKA website.
Typical certication information label
2. INSTALLATION
The BA334G Rate Totaliser has a robust IP66 glass reinforced
polyester (GRP) carbon loaded enclosure incorporating an
armoured glass window & stainless steel ttings. It is suitable
for exterior surface mounting in most industrial environments,
or pipe mounting using an accessory kit.
If the enclosure is not bolted to an earthed post or structure,
the earth terminal on the cable entry bonding plate, which
may be assembled on the inside or outside of the enclosure,
should be connected to local earthed metalwork or to the
plant’s potential equalising conductor.
Terminals A1, A2, A3 and A4 are only tted when the Rate
Totaliser includes optional alarms. Similarly terminals C1, C2,
C3 and C4 are only tted when the instrument has an optional
4/20mA output. See full manual for details.
Step C
Remove the temporary
hole plug and install an
appropriate IP rated cable
gland or conduit fitting.
Feed the field wiring
through the cable entry.
Step D
Terminate field wiring on the
instrument assembly. Replace
the assembly on the enclosure
back-box and tighten the four
'A' screws.
Step B
Secure the enclosure
back-box to a flat surface
with M6 screws through
the four 'B' holes. Alternatively
use a pipe mounting kit.
Step A
Unscrew the four captive
'A' screws and separate
the indicator assembly
and the back-box.

Scale card
The instrument’s units of measurement and tag information
are shown above the display on a slide-in scale card.
New instruments are tted with a scale card showing the
information specied when the instrument was ordered, if this
was not provided a blank scale card will be tted which can
easily be marked on-site. Custom printed scale cards are
available from BEKA associates.
To remove the scale card carefully pull the tab perpendicularly
away from the instrument assembly. See Fig 2 for the location
of the scale card tab.

Fig 4 Inserting scale card into instrument assembly
To replace the scale card carefully insert it into the slot shown
in Fig 2. Force should be applied evenly to both sides of the
scale card to prevent it twisting. The card should be inserted
until about 2mm of the transparent tab remains protruding.
3. OPERATION
The BA334G is controlled and congured via four front panel
push buttons. In the display mode i.e. when the instrument
is displaying ow the push button functions are:
) + & Grand total - shows Lo followed by least signicant
8 digits of the 16 digit grand total.
) + * Grand total - shows Hi followed by the most
signicant 8 digits of the 16 digit grand total.
If Local Grand Total Reset CLr Gtot in the
instrument conguration menu has been activated,
operating the ) and * buttons for ten seconds
will result in Clr. no being displayed with the
no ashing. Operating the & or * button will
change the display to CLr . YE5, the ) button
will then reset the grand total to zero which will be
conrmed by a brief display of Gt Clrd.
& + * If Local Total Reset CLr tot in the instrument
conguration menu has been activated, operating
the & and * buttons for three seconds will
reset the total display to zero and clear any pulses
stored in the optional pulse output. The Grand
Total is not reset.
( + & Shows in succession, rmware version number,
instrument function totali5e and any output

-A Dual alarm outputs
-P Pulse output (always tted)
-c 4/20mA output
( + * Provides direct access to the alarm setpoints when
the Rate Totaliser is tted with optional alarms and
the AC5P setpoints function has been enabled.

4. CONFIGURATION
Rate Totalisers are supplied configured as requested at time of ordering, if not specified default configuration will be supplied but can easily be changed on-site. Fig 5 shows the location of each
function within the configuration menu with a brief summary of the function. Please refer to the full instruction manual for detailed configuration information and for description of optional outputs.
Access to the configuration menu is obtained by pressing the ( and ) buttons simultaneously. If the Rate Totaliser's security code is set to default 0000 the first parameter function will be
displayed. If the instrument is protected by a security code, code will be displayed. The four digit code must be entered to gain access to the menu.
Unless otherwise specified menu functions are shown on the upper display
