DocumentDocument1. DESCRIPTION The BA584G is a field mounting general purpose, two input Rate Totaliser which 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. 2. INSTALLATION The BA584G 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.

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. 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 BA584G 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: & or * Scrolls both displays 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 clr gtot is enabled. To reset the grand total to zero from the operating mode press the ) and * buttons for ten seconds until CLr. no is displayed. Using the & or * button change the display to Clr .

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. * Followed by identical function for input b When fitted with optional alarms functions appear here When fitted with optional 4/20mA output functions appear here () ) & function * & input-a * * ) ) ) ) ) ) ) ) ) ) ) ) & update * & count * & di5p-1 * & di5p-2 * & dP * & ** & factor-a ** & 5cale . t-a ** & 5cale . r-a t-ba5e * & ** & filter-a ** & clp. off-a Loc clr * ) ) ) ) ) & e clr * & pul5e op * & clr gtot * & code * & r5et def * () 5td () ) inp.type * & debounce () 0 . 5 () a : b () total () 5td () 0000 . 0 () 001 . 00 () 001 . 00 () 001 . 00 () tb-01 () 24 () 0000 . 0 () ) clr tot * & clr gtot () ( r5et-both () no () 0000 () 0000 () () () () () op.col default off off 0000 Function * or & to select Function of instrument 5td linear lin 16 segment lineariser Input-A * or & to select Debounce input-A * or & to select Input type op.col Open Collector. volt5 l Pulse <1V >3V volt5 h Pulse <3V >10V coil Magnetic pick-off. pr.det Proximity detector. contact Switch contact. level of debounce. default light heavy Update * or & to select interval between display updates, may be set to 0.5, 1, 2, 3, 4 or 5 seconds.
