4.1 FISCO SystemsThe BA448CF-F may be connected to any ATEXcertified FISCO compliant fieldbus segment,providing the segment can supply the additional13mA required to power the instrument.

Fig 1 shows a typical fieldbus segment. To complywith FISCO requirements, the power supply,terminators, field devices and the interconnectingcables must conform to EN 60079 part 27.

Fig 1 FISCO fieldbus system

4.2 Non-FISCO SystemsFor non-FISCO applications the BA448CF-FFieldbus Indicator has a higher voltage entityintrinsic safety input parameter allowing connectionto a wide range of fieldbus segments.

The BA448CF-F Fieldbus Indicator may beconnected to any intrinsically safe segmentproviding:

The device powering the fieldbus segment isATEX certified and has output parametersequal to or less than:

Uo = 22V dcIo = 250mA dcPo = 1.2W

The segment can provide an additional13mA to power the Fieldbus Indicator.

Note: The equivalent capacitance Ci of theBA448CF-F Fieldbus Indicator is zero and theequivalent inductance is insignificant. Thereforethese BA448CF-F safety parameters do not needto be considered.

6.3 Listener configuration menuThe listener configuration menu is separated intothree sections, ‘SCAn’, ‘LISt’ and ‘Edit’, plus threehousekeeping functions ‘CodE’, ‘tYPE’ and ‘rESEt’as shown in Fig 6.

‘SCAn’ is the simplest method of configuration ifthe fieldbus Device Address and Variable Identityof the data to be displayed by the BA448CF-Flistener are not known.

In the ‘SCAn’ function pressing the P buttoncauses the BA448CF-F indicator to search thefieldbus segment to which it is connected for allpublishers. Fig 5 shows how the indicator displaysthe hexadecimal Device Address and VariableIdentity associated with each publisher.

A Publisher is a device that places it's outputdata onto the bus as part of a cyclical pre-determined data exchange schedule.

The Device Address is a unique address thatidentifies each fieldbus instrument connected tothe bus.

The Variable Identity is the fieldbus deviceData Link Connection End Point (DLCEP)which identifies each Function Block output(process variable) transmitted by a fieldbusdevice such as flow and temperaturetransmitted by a fieldbus flowmeter.

The ▼ and ▲ push buttons scroll the displaythrough all the publishers on the segment showingthe Device Address and Variable Identity for eachone - see Fig 5. To aid identification, operatingthe P button will preview the value of the data ateach selected address, if required it may then beallocated to one of the eight BA448CF-F listenerinputs in-1, to in-8 by operating the P button again.If the format of the data at the selected DeviceAddress and Variable Identity is not DS-65 (float +status) ‘no dAt’ will be displayed.

Fig 5 Device Address and Variable Identity

If the Device Address and Variable Identity of theprocess variable to be displayed by the BA448CF-F indicator are known, they may be directlyentered via the edit sub-menu. This sub-menualso provides full control of both the numeric andbargraph display parameters.

6.3.3 Scan fieldbus segment ‘SCAn’If the Device Address and Variable Identity of aprocess variable are not known, the ‘SCAn’function provides a simple way to identify them.This function scans the fieldbus segment to whichthe BA448CF-F indicator is connected andidentifies all the publishers. To aid identification itenables the value of each process variable to bepre-viewed and, if required, allocated to one of theeight BA448CF-F Fieldbus indicator inputs.

The BA448CF-F indicator only supports DS-65formatted data (float + status) which is the usualformat for analogue process variables. The‘SCAn’ function will identify all publishers on thesegment irrespective of format, but when pre-viewed, non DS-65 formatted data will produce a‘no dAt’ error message.

‘SCAn’ is the first function displayed when enteringthe listener configuration menu, or it may beselected from within the menu by operating the ▼or ▲ button. To scan the fieldbus segment towhich the indicator is connected for all publisheddata press P which will reveal the hexadecimalDevice Address and Variable Identity of the firstpublisher found as shown in Fig 5. If there ismore than one publisher operating the ▼ or ▲

button will scroll though all of them.

If no cyclic data is being published on the fieldbussegment the BA448CF-F indicator will display‘noPub’.

When the Device Address and Variable Identity ofa process variable is being displayed, pressing Pwill preview the value of the process variabledisplayed with maximum resolution on the five digitdisplay. If this confirms that it is one of theprocess variables to be displayed, it may beallocated to one of the eight BA448CF-F listenerinputs in-1 to in-8.

To select the required listener input press P todisplay the first input in-1, operating the ▼ or ▲

button will scroll the display through the otherinputs. When the required input is displayedpressing E will allocate the selected processvariable to the selected input and return the displayto the Device Address and Variable Identity fromwhich another process variable may be selected.

When a process variable is allocated to a indicatorinput any previous allocation will be overwritten.

6.3.4 List configured input parameters ‘LiSt’The ‘LiSt’ function enables the Device Address andVariable Identity allocated to each lindicator inputto be viewed without danger of it being accidentallychanged.

The ‘LiSt’ function may be selected from within themenu by operating ▼ or ▲ button. To enter thefunction press P which will display the indicatorinput currently selected in the display mode, otherinputs may be selected using the ▼ or ▲ button.Operating the P button will cause the followingparameters for the selected input to be displayedsequentially:

Display Explanation‘Enb: Y or N’ Input Enabled yes or no‘Adr: 00’ Device Address ‘id: 00’ Variable Identity

The display then automatically returns to theselected BA448CF-F indicator input from whereanother input may be selected.

If one of the eight BA448CF-F indicator’s inputs in-1 to in-8 has not had a Device Address andVariable Identity allocated to it, ‘LiSt’ will show bothas invalid address FF.

6.3.5 Enter address & display parameters ‘Edit’The ‘Edit’ function may be selected from within themenu by operating ▼ or ▲ button. To enter thefunction press P which will display the indicatorinput currently selected in the display mode, otherlistener inputs may be selected using the ▼ or ▲button. When the required input has beenselected operating the P button will enter the editsub-menu at ‘Enb’ for the selected input.

6.3.6 Enable selected input ‘Enb’‘Enb’ turns the indicator input selected in the Editfunction on or off without affecting the conditioning.To enter the function press P which will revealwhether the selected input is ‘on’ or ‘oFF’.Operating the ▼ or ▲ buttons will toggle betweenthe two conditions. When set as requiredoperating the E button will enter the selection andreturn to the edit sub-menu.

‘bArLo’ defines the indicator’s numeric display atwhich the bargraph starts, to enter the functionpress P which will reveal the existing setting. Thedisplay may be changed using the ▼ or ▲ buttonto adjust the flashing digit and the P button tomove control to the next digit. When the requiredstarting display has been selected, press E toreturn to the ‘bArLo’ prompt in the edit sub-menufrom which the ‘bArHi’ function may be selected.

‘bArHi’ defines the indicator’s numeric display atwhich the bargraph is full scale, to enter thefunction press P which will reveal the existingsetting. The display may be changed using the ▼or ▲ button to adjust the flashing digit and the Pbutton to move control to the next digit. When therequired display has been selected, press E twiceto enter the new values and return to the ‘bAr’prompt in the edit sub-menu.

Note: If the ‘dP’ function has been set to provideautomatic maximum resolution irrespective of thedisplayed value, it may be necessary to manuallyposition the decimal point before adjusting ‘bArLo’or ‘bArHi’. This can be achieved by repeatedlyoperating the P button until the activated decimalpoint flashes, the decimal point can then bepositioned using either the ▼ or ▲ button.Pressing the P button again will return control toone of the digits.

6.3.11 Scale numeric display ‘SCALE’A scaling factor ‘Gain’ and an offset ‘oFFSt’ maybe applied to the fieldbus process variable usingthis function, thus allowing the indicator to displaythe fieldbus process variable in alternative units.

The ‘SCALE’ function may be selected from withinthe edit sub-menu by operating the ▼ or ▲ button.To enter the function press P which will display the‘GAin’ sub-function, pressing P again will revealthe existing gain with one digit flashing. Thisflashing digit may be changed by operating the ▼or ▲ button; when adjusted the P button will movecontrol to the next digit or to the decimal pointwhich can be positioned using the ▼ or ▲ button.When ‘GAin’ has been set to the required valueoperating the E button will enter the selection andreturn to the ‘GAin’ prompt in the sub-menu fromwhere the ‘oFFSt’ function can be selected usingthe ▼ or ▲ button.

7.2 Fault finding after commissioning

ENSURE PLANT SAFETY BEFORESTARTING MAINTENANCE

Live maintenance is permitted onintrinsically safe equipment installed in ahazardous area, but only certified testequipment should be used unless a gasclearance certificate is available.

If a BA448CF-F fails after it has been functioningcorrectly, the table shown in section 7.1 may helpto identify the cause of the failure.

If this procedure does not reveal the cause of thefault, it is recommended that the instrument isreplaced.

7.3 ServicingWe recommend that faulty BA448CF-F Fieldbusindicators are returned to BEKA associates or toour local agent for repair.

7.4 Routine maintenanceThe mechanical and electrical condition of theinstrument should be regularly checked. Initiallyannual inspections are recommended, but theinspection frequency should be adjusted to suit theenvironmental conditions.

7.5 GuaranteeInstruments which fail within the guarantee periodshould be returned to BEKA associates or our localagent. It is helpful if a brief description of the faultsymptoms is provided.

7.6 Customer commentsBEKA associates is always pleased to receivecomments from customers about our products andservices. All communications are acknowledgedand whenever possible, suggestions areimplemented.

A1.0 Factory Mutual ApprovalFor installations in the USA and Canada, theBA448CF-F has FM and cFM intrinsic safety andnonincendive approval, project identifications3027031 and 3027031C. Copies of theCertificates of Compliance are available fromBEKA associates sales office and www.beka.co.uk

A1.1 Intrinsic safety approvalThe BA448CF-F is approved to FM Class 3610intrinsic safety standard for use in hazardous(classified) locations. Installations must complywith BEKA associates Control Drawing CI410-12,which is attached to this Appendix, ANSI/ISARP12.06.01 ‘Installation of Intrinsically SafeSystems for Hazardous (Classified) Locations’ andwith the National Electrical Code ANSI/NFPA70.

Canadian installations must comply with theCanadian Electrical Code C22.2 and with BEKAassociates Control Drawing CI410-12, which isattached to this Appendix.

The BA448CF-F has a T4 rating at ambienttemperatures up to +70oC and may be used withthe following gases and dusts:

Intrinsic SafetyDivision 1 or 2

Class I Group A & B Group C Group D

Class II Group E, F & G

Class III

Zone 0, 1 or 2Class 1 Group IIC Group IIB Group IIA

The FM and cFM entity parameters are identical tothe ATEX parameters and, like the ATEXcertification, confirm that the BA448CF-F complieswith the FISCO Field Device requirementsspecified in IEC60079-27. The intrinsically safesystem shown in Fig 1 of this manual maytherefore be used for installations in the USA andCanada, providing the fieldbus power supply,terminators, Zener barriers and galvanic isolatorsare FM Approved for US installations and cFM orCSA Approved for Canadian installations. Allinstallations must comply with BEKA associatesControl Drawing CI410-12.

FM and cFM Approvals also allows the BA448CF-F to be connected to non-FISCO systems usingthe entity concept – see section 4.2 of this manual.

A1.2 Nonincendive approvalThe BA448CF-F is FM Class 3611 nonincendiveapproved allowing it to be installed in Division 2hazardous (classified) locations without the needfor Zener barriers or galvanic isolators. USinstallations must comply with the BEKAassociates Control Drawing CI410-13, which isattached to this Appendix, and with the NationalElectrical Code ANSI/NFPA70.

Canadian nonincendive installations must complywith the Canadian Electrical Code C22.2 and withBEKA associates Control Drawing CI410-13, whichis attached to this Appendix.

The FM and cFM Nonincendive Approvals alsoallow the BA448CF-F fieldbus indicator to beconnected to any appropriately certified FNICOcompliant fieldbus segment.

APPENDIX 2IECEx Certification

A2.0 The IECEx Certification SchemeIECEx is a global certification scheme forexplosion protected products which aims toharmonise international certification standards.For additional information about the IECExcertification scheme and to view the BEKAassociate certificates, please visit www.iecex.com

A2.1 IECEx Certificate of ConformityThe BA448CF-F Fieldbus Indicator has beenissued with an IECEx Certificate of Conformitynumber IECEx ITS 06.0013X which specifies thefollowing certification codes and marking:

Ex ia IIC T4 GaFISCO Field Device Ex ia IIC T4Ta = -40oC to 70 oC

See below for details of safe use in Zone 0.

CAUTIONInstallation in Zone 0

When installed in a Zone 0 potentiallyexplosive atmosphere, the indicator shall beinstalled such that even in the event of rareincidents, an ignition source due to impactor friction between the aluminium enclosureat the rear of the instrument mounting paneland iron/steel is excluded.

When connected to an IECEx certified system theBA448CF-F may be installed in:

Zone 0 explosive gas air mixturecontinuously present.Note: Special conditions forsafe use apply see above.

Zone 1 explosive gas air mixturelikely to occur in normaloperation.

Zone 2 explosive gas air mixture notlikely to occur, and if it does willonly exist for a short time.

Be used with gases in groups:Group A propaneGroup B ethyleneGroup C hydrogen

Having a temperature classification of:

T1 450oC

T2 300oC

T3 200oC

T4 135oC

At an ambient temperature between –40 and+70oC.Note : the guaranteed operating temperature rangeof the BA448C Fieldbus Indicator is –20 to +70oC

The IECEx safety parameters are identical to theATEX parameters and, like the ATEX certification,confirm that the BA448CF-F complies with theFISCO Field Device requirements specified inIEC60079-27.

The IECEx certificate may be downloaded fromwww.beka.co.uk, www.iecex.com or requestedfrom the BEKA sales office.

A2.2 InstallationThe BA448CF-F IECEx and ATEX certificationshave identical intrinsic safety parameters andinstallation requirements. The ATEX systemdesign requirements described in section 4 of thismanual may therefore be used for IECExinstallations, but the local code of practice shouldalways be consulted.
