BEKA BA334G Externally Powered Rate Totaliser
DESCRIPTION
- The BA334G is a field mounting intrinsically safe, one input Rate Totaliser which will function with a wide variety of sensors. The instrument can display rate of flow and total flow in the same or different engineering units.
- This abbreviated instruction sheet is intended to assist with installation, a comprehensive instruction manual describing safety certification, system design and configuration may be downloaded from the BEKA website or may be requested from the BEKA sales office.
- The BA334G Rate Totaliser has IECEx, ATEX, UKEX, ETL and cETL intrinsic safety certification for use in flammable gas and dust atmospheres. The certification information label, which is located on the top of the instrument assembly, shows the certification numbers and codes. Other certifications may be shown. Copies of certificates may be downloaded from the BEKA website.

INSTALLATION
-
The BA334G Rate Totaliser has a robust IP66 glass reinforced polyester (GRP) carbon loaded enclosure incorporating an armoured 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 equalising 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 captive ‘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 screened twisted pairs with
screens earthed at one point within the safe area.
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.
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.
OPERATION
The BA334G is controlled and configured via four front panel push buttons. In the display mode i.e. when the instrument is displaying flow the push button functions are:
-
Grand total – shows Lo followed by least significant 8 digits of the 16 digit grand total.
-
Grand total – shows Hi followed by the most significant 8 digits of the 16 digit grand total.
If Local Grand Total Reset in the instrument configuration menu has been activated, operating the buttons for ten seconds will result in . no being displayed with the no flashing. Operating the button will change the display to CLr . YE5 , the ) button will then reset the grand total to zero which will be confirmed by a brief display of Gt Clrd. -
If Local Total Reset CLr tot in the instrument configuration menu has been activated, operating the 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, firmware version number, instrument function totali5e and any output accessories that are fitted:
- A Dual alarm outputs
- P Pulse output (always fitted)
- C 4/20mA output
-
Provides direct access to the alarm setpoints when the Rate Totaliser is fitted with optional alarms and the AC5P setpoints function has been enabled.
-
Access to configuration menu
CONFIGURATION
Rate Totalisers are supplied configured as requested at 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 description of optional outputs. Access to the configuration menu is obtained by pressing the 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.
The BA334G is CE marked to show compliance with the European Explosive
Atmospheres Directive 2014/34/EU and the European EMC Directive 2014/30/EU.
It is also UKCA marked to show compliance with UK statutory requirements
Equipment and Protective Systems Intended for Use in Potentially Explosive
Atmospheres Regulations UKSI 2016:1107 (as amended) and with the
Electromagnetic Compatibility Regulations
UKSI 2016:1091 (as amended).
