INSTALLATION
The BA334E Rate Totaliser has a robust IP66 GRP enclosure with a separate terminal compartment 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 should be connected to local earthed metalwork or to the plant’s potential equalising conductor.
Dimensions
EMC
For specified immunity all wiring should be in screened twisted pairs with
screens earthed at one point within the safe area.
Units of measurement and tag number
The BA334E is fitted with a blank escutcheon around the liquid crystal display. This can be supplied printed with any units of measurement and tag information specified at the time of ordering. Alternatively, the information may be added on-site via an embossed strip, dry transfer or a permanent marker.
To gain access to the escutcheon remove the terminal cover by unscrewing the two ‘A’ screws which will reveal two concealed ‘D’ screws. Remove the push buttons by unscrewing the two ‘C’ screws and un-plug the five way connector. Finally, unscrew all four ‘D’ screws and carefully lift off the front of the instrument. The location of all the screws is shown in Fig 1.
OPERATION
The BA334E 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
