Abbreviated Instructions for
BA554E general purpose field
mounting loop powered rate totaliser
Issue 2
10th March 2014
DESCRIPTION
The BA554E is a field mounting, general purpose, 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 system design and configuration is available from the BEKA sales office or may be downloaded from our webste.
INSTALLATION
The BA554E 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.
| Step 1
Remove the terminal cover by unscrewing the two ‘A’ screws
---|---
| Step 2
Secure the instrument to a flat surface with M6 screws through the two ‘B’
holes.
Alternatively use a pipe mounting kit.
| 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.
EMC
The BA554E complies with the European EMC Directive 2004/108/EC. For specified
immunity all wiring should be in screened twisted pairs, with the screens
earthed in the safe area.
Units of measurement & tag number
The BA554E 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 BA554E 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:
P 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
E 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
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.
