DocumentDocument1. 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. Typical certification 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 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. A A DISPLAY A A Step A Unscrew the four captive 'A' screws and separate the indicator assembly and the back-box. B B Insulated stud for joining cable screens Earth B stud B 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. A A Step D Terminate field wiring on the instrument assembly. Replace the assembly on the enclosure back-box and tighten the four A A 'A' screws.

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.

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. 3. 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 CLr Gtot in the instrument configuration menu has been activated, operating the ) and * buttons for ten seconds will result in Clr. no being displayed with the no flashing. Operating the & or * 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 & 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.

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.
