DESCRIPTION

The BA354E is a field mounting, intrinsically safe, 4/20mA

rate totaliser primarily intended for use with flowmeters. It

simultaneously displays the rate of flow (4/20mA current) and

the total flow in engineering units on separate displays. It is

loop powered but only introduces a 1.2V drop into the loop.

This abbreviated instruction sheet is intended to assist with installation and commissioning, a comprehensive instruction manual describing safety certification, system design and configuration is available from the BEKA sales office or may be downloaded from our website.

The BA354E has IECEx, ATEX and UKEX intrinsic safety certification for use in flammable gas atmospheres. The certification label, which is located on the top of the instrument enclosure shows the certificate numbers and the certification codes. Copies of certificates may be downloaded from our website.

Gas certification label
CAUTION Special conditions apply for installation in Zone0.
See certificates of full instruction manual
Dust certification is available as a factory option, which must be requested when the instrument is ordered. The dust and gas certification label is shown below.

For installations in the USA and Canada, versions with FM and cFM approval are available.

INSTALLATION

The BA354E rate totaliser has a robust IP66 glass reinforced

polyester (GRP) enclosures incorporating an armoured glass

window and stainless steel fittings. It is suitable for exterior

mounting in most industrial environments.

It is surface mounting, but may be pipe mounted using one of the accessory kits.

DISPLAY

Step 1 Remove the terminal cover by unscrewing the two 'A' screws

DISPLAY

Step 2 Secure the instrument to a flat surface with M6 screws through the two 'B' holes. Alternatively use a pipe mounting kit.

DISPLAY

Step 3 and 4 Remove the temporary hole plug and install appropriate IP rated cable gland or conduit fitting and terminate field wiring. Replace the terminal cover and tighten the two 'A' screws.

Fig 1 shows the installation procedure.

The rate totaliser's earth terminal is connected to the carbon loaded GRP enclosure. If this enclosure is not bolted to an earthed post or structure, the earth terminal should be connected to the plant potential equalising conductor.

A bonding plate is provided to ensure electrical continuity between the three conduit / cable entries.

Terminals 8, 9, 10 & 11 are only fittted when the rate totaliser includes optional alarms. See full manual for details.

Terminals 12, 13 & 14 are only fitted when the rate totaliser includes an optional backlight. See full manual for details.

Fig 3 Typical measurement loop

Units of measurement & tag number The BA354E has an escutcheon around the liquid crystal display which can be supplied printed with any units of measurement and tag information specified when the instrument was ordered. If no information was supplied a blank escutcheon will be fitted but legends may be added on-site via an embossed strip, dry transfer or a permanent marker. Custom printed escutcheons are available from BEKA as an accessory which should be fitted on top of the blank escutcheon. Do not remove the blank escutcheon.
To gain access to the escutcheon remove the terminal cover by unscrewing the two `A' screws which will reveal two concealed `D' screws. If the instrument is fitted with an external keypad, also unscrew the two `C' screws securing the keypad and un-plug the five way connector. Finally unscrew all four `D' screws and carefully lift off the front of the instrument. Add the required legend to the escutcheon, or stick a new printed self-adhesive escutcheon on top of the existing escutcheon.

OPERATION

The BA354E is controlled and configured via four push

buttons located behind the instrument control cover, or via an

optional keypad on the outside of the control cover. In the

display mode i.e. when the instrument is totalising, these push

buttons have the following functions:

Displays input current in mA or as a percentage of

span. (configurable function)

Modified when optional alarms are fitted.

Shows rate display calibration at 4mA input

Shows rate display calibration at 20mA input

Shows time since instrument was powered or total

display was reset.

E+ Grand total displays least significant 8 digits

E+ Grand total displays most significant 8 digits

+ Resets total display (configurable function)

P+ Shows firmware version

P+ Optional alarm setpoint access

P+E Access to configuration menu

4. CONFIGURATION
Totalisers are supplied calibrated as requested when ordered, if not specified default configuration will be supplied but can easily be changed on-site.
Fig 4 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 description of the lineariser and the optional dual alarms.
Access to the configuration menu is obtained by pressing the P and E buttons simultaneously. If the totaliser security code is set to the default `0000' the first parameter `FunC' will be displayed. If the totaliser is protected by a security code, `CodE' will be displayed and the code must be entered to obtain access to the menu.
