BEKA BA358E Loop Powered Instruction Manual
The BA358E is a panel 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 calibration is available from the BEKA sales office or may be downloaded from our webmalo.
The BA358E has IECEx, ATEX and UKEX intrinsic safety certification for use in flammable gas & dust atmospheres. FM and cFM approval also permits installation in the USA and Canada. 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 webmalo.

The IECEx, ATEX and UKEX certificates have an ‘X’ suffix indicating that special conditions apply for safe use.
To avoid an electrostatic charge being generated instrument enclosure should only be cleaned with a damp cloth. Special conditions also apply for use in IIIC conductive dusts – please see full manual.
The BA358E has IP66 front of panel protection but it should be shielded from direct sunlight and severe weather conditions. The rear of the rate to taliser has IP20 protection.
Recommended for all installations. Mandatory to achieve an IP66 seal between the instrument and the panel 136 +0.5/-0.0 x 66.2 +0.5/-0.0

Chithunzi cha 3 Typical measurement loop
The rate totaliser’s units of measurement are shown on a printed scale card visible through a window at the right hand side of the display. The scale card is mounted on a flexible strip that is inserted into a slot at the rear of the instrument a shown below.

he instrument from the panel or opening the instrument
New rate totalisers are supplied with a printed scale card showing the requested units of measurement, if this information was not supplied when the instrument was ordered a blank card will be fitted.

The BA358E is controlled and configured via the four front panel push buttons located below the display. 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+▼ Ikuwonetsa mtundu wa firmware
P+▲ Optional alarm setpoint access
P+E Access to configuration menu
Totalisers are supplied calibrated as requested when ordered, if not specified default configuration will be supplied but can easily be changed on-site.
Chithunzi cha 6 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.
