BEKA BA367E-SS Counters Intrinsically safe
DESCRIPTION
The BA367E-SS is an intrinsically safe, one input Counter housed in a rugged
316 stainless steel panel mounting enclosure which can operate with a wide
range of sensors.
This abbreviated instruction sheet is intended to assist with installation, a
comprehensive instruction manual describing safety certification, system
design and configuration may be downloaded from the BEKA website or may be
requested from the BEKA sales office. The BA367E-SS has IECEx, ATEX and UKEX
intrinsic safety certification for use in flammable gas and dust atmospheres.
ETL and cETL approval permits installation in the USA and Canada. The
certification information label, which is located on the top of the instrument
enclosure, shows the certification number and codes. Other certifications may
be shown. Copies of certificates may be downloaded from the BEKA website.
Special conditions for safe use
The IECEx, ATEX and UKEX intrinsic safety certificate numbers have an ‘X’
suffix indicating that for some applications special conditions apply for safe
use.
-
When installed in an Ex e, Ex p or Ex t panel enclosure all connections to the BA367E-SS must be made by appropriately rated Zener barriers or galvanic isolators.
This means that when installed in an Ex e, Ex p or Ex t panel enclosure the BA367E-SS remains an intrinsically safe instrument. -
The front of the stainless steel enclosure complies with the requirements for Ex e, Ex p & Ex t type of protection.
Therefore when correctly installed the BA367E-SS Counter will not invalidate the Ex e, Ex p or Ex t panel enclosure certification.
Use in combustible dust atmospheres
See full instruction manual for installation information requirements and
special conditions for safe use in combustible dust atmospheres.
INSTALLATION
Cut-out dimensions
Mandatory to achieve an IP66 seal between instrument and panel and to maintain
certification of panel enclosure in which it is mounted.

EMC
For specified immunity all wiring should be in screened twisted pairs with
screens earthed at one point within the safe area
Scale card
The Counters 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 as shown below
Thus the scale card can easily be changed without removing the Counter from the panel or opening the instrument enclosure. New Counters are supplied with a printed scale card showing the requested units of measurement, if this information is not supplied when the Counter is ordered a blank card will be fitted. A pack of self-adhesive scale cards printed with common units of measurement is available as an accessory from BEKA associates. Custom printed scale cards can also be supplied. To change a scale card, unclip the protruding end of the flexible strip by gently pushing it upwards and pulling it out of the enclosure. Peel the existing scale card from the flexible strip and replace it with a new printed card, which should be aligned as shown below. Do not fit a new scale card on top of an existing card.
OPERATION
The Counter is controlled by four front panel push buttons. When in the operating mode they have the following functions
- Access to configuration menu.
- If Local Total Reset CLr tot in the instrument configuration menu has been activated, operating the & and * buttons simultaneously for three seconds will reset the total display to zero and clear any pulses stored in the optional pulse output.
- Grand total – shows Lo followed by least significant 8 digits of the 16 digit grand total. Grand total – shows Hi followed by the most significant 8 digits of the 16 digit grand total. If Local Grand Total Reset Clr Gtot in the instrument configuration menu has been activated, operating the ) and buttons simultaneously for ten seconds will result in Clr no being displayed with the no flashing. Operating the or & button will change the display to Clr . YE5, the ) button will then reset the grand total to zero which will be confirmed by a brief display of Gt Clrd.
- & Shows in succession, firmware version number, instrument function counter and any output accessories that are fitted:
- A Dual Alarm Outputs
- P Pulse output
- C 4/20mA output.
- When optional alarms are fitted provides direct access to the alarm setpoints if A5CP (access setpoints) has been enabled in the configuration menu.
