BEKA BA364E User manual

Brand: BEKA

Model: BA364E

Type: User manual

BEKA BA364E intrinsically safe two-input field-mounting counter offers versatile counting solutions in potentially explosive atmospheres. Its robust IP66 GRP enclosure and separate terminal compartment with armored glass window ensure durability. Easily mount it on a flat surface or pipe using the included accessories. The BA364E provides rate and total display of two inputs, their sum, or difference. It features configurable parameters like input type, counting edge, display updates, and decimal point position.

1. DESCRIPTION

The BA364E is a eld mounting intrinsically safe, two input

Counter with a separate terminal compartment which will

function with a wide variety of sensors. The instrument

can display rate and total of the two inputs and their sum or

dierence.

This abbreviated instruction sheet is intended to assist with

installation, a comprehensive instruction manual describing

safety certication, system design and conguration may be

downloaded from the BEKA website or may be requested

from the BEKA sales oce.

The BA364E Counter has IECEx, ATEX and UKEX intrinsic

safety certication for use in ammable gas atmospheres,

plus ETL and cETL gas and dust certication. The certication

information label, which is located on the top of the instrument

assembly, shows the certication numbers and codes. Other

certications may be shown. Copies of certicates may be

downloaded from the BEKA website.

2. INSTALLATION

The BA364E Counter has a robust IP66 GRP enclosure with

a separate terminal compartment incorporating an armoured

glass window & stainless steel ttings. 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.

Step C and D

Remove the temporary

hole plug and install an

appropriate IP rated cable

gland or conduit fitting and

terminate field wiring.

Finally replace the terminal

cover and tighten the two

'A' screws.

Step B

Secure the instrument

to a flat surface with M6

screws through the

two 'B' holes.

Alternatively use a pipe

mounting kit.

Step A

Remove the terminal

cover by unscrewing

the two 'A' screws

Units of measurement and tag number

The BA364E is tted with a blank escutcheon around the

liquid crystal display. This can be supplied printed with any

units of measurement and tag information specied 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 ve way connector. Finally,

unscrew all four ‘D’ screws and carefully lift o the front of the

instrument. The location of all the screws is shown in Fig 1.

3. OPERATION

The BA364E is controlled and congured via four front panel

push buttons. In the display mode i.e. when the instrument

is counting the push button functions are:

) + & Grand total - shows the least signicant 8 digits of

a 16 digit counter.

) + * Grand total - shows the most signicant 8 digits of

a 16 digit counter. If buttons are pressed for longer

than 10 seconds the grand total will be reset to zero

if the grand total reset function clr gtot is enabled.

To reset the grand total to zero from the operating

mode press the ) and * buttons for ten seconds

until CLr. no is displayed. Using the & or * button

change the display to Clr . YE5 and press ) which will

reset the grand total and restore the original display.

& + * If the local total reset function clr tot is enabled in

the conguration menu, simultaneously pressing

the & and * buttons for more than three seconds

allows total A, total b or both totals to be selected

by operating the & or * button. Operating the

) button will then reset the selected total and

clear any stored output pulses.

4. CONFIGURATION

Counters are supplied configured as requested at time of ordering, 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. Access to the configuration menu

is obtained by pressing the ( and ) buttons simultaneously. If the Counter's security code is set to default 0000 the first parameter input-a will be displayed. If the instrument is protected

by a security code, code will be displayed. The four digit code must be entered to gain access to the menu.
