DESCRIPTION
The BA584G is a field mounting general-purpose, two-input Rate Totaliser that
will function with a wide variety of sensors. The instrument can display rate
of flow and total
flow of the two inputs and their sum or difference. This abbreviated
instruction sheet is intended to assist with installation, a comprehensive
instruction manual describing
system design and configuration may be downloaded from the BEKA website or may
be requested from the BEKA sales office.
INSTALLATION
The BA584G Rate Totaliser has a robust IP66 glass reinforced polyester (GRP)
carbon loaded enclosure incorporating an armored glass window & stainless
steel fittings. 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 equalizing conductor.
Terminals A1, A2, A3, and A4 are only fitted when the Rate Totaliser includes
optional alarms. Similarly, terminals C1, C2, C3, and C4 are only fitted when
the instrument has an optional 4/20mA output. See full manual for details.
Step A
Unscrew the four captives ‘A’ screws and separate the indicator assembly and
the back-box. 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 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.

EMC
For specified immunity, all wiring should be in screen twisted pairs with
screens earthed at one point.

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 fitted with a scale card
showing the
information specified when the instrument was ordered, if this was not
provided a blank scale card will be fitted 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 from twisting. The card should be inserted until about 2mm of the transparent tab remains protruding.
OPERATION
The BA584G is controlled and configured via four front panel pushbuttons. In the display mode i.e. when the instrument is displaying flow the push button functions are:
Scrolls both display between:
Input **A**
Input **b**
Input **A + b**
or Input **A – b**
which is configurable
Grand total – shows **Lo**
followed by the least significant 8 digits of a
16 grand total.
Grand total – shows **Hi**
followed by the most significant 8 digits of a 16
digit grand total. If buttons are pressed for longer than 10 seconds the grand
total will be reset to zero if the grand total reset function is enabled.
To reset the grand total to zero from the operating mode press the and buttons
for ten seconds until . no is displayed. Using the & button change the display
to . YE5 and press which will reset the grand total and restore the original
display.
If the local total reset function tot is enabled in the configuration menu,
simultaneously pressing the buttons for more than three seconds allows total
A, total b or both totals to be selected by operating the button. Operating
the button will then reset the selected total to zero and clear any stored
output pulses.
Shows each for 2 seconds:

CONFIGURATION
Rate Totalisers are supplied configured as requested at the time of order, 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 a
