4. WIRING

4. WIRINGThis chapter describes the wiring on the converter sideonly. For information relating to wiring on theflowtube side, refer to the user’s manual of the AXFRemote Flowtube (IM 01E20D01-01E).

WARNING

The wiring of the magnetic flowmeter must beperformed by expert engineer or skilled person-nel. No operator shall be permitted to performprocedures relating to wiring.

CAUTION

Once all wiring is complete, check the connec-tions before applying power to the instrument.Improper arrangements or wiring may cause aunit malfunction or damage.

4.1 Wiring PrecautionsBe sure to observe the following precautions whenwiring:

CAUTION

• Do not splice the cable between the flowtubeterminal and the converter if it is too short.Replace the short cable with a cable that is theappropriate length.

• In cases where the ambient temperatureexceeds 50°C (122°F), use external heat-resistant wiring with a maximum allowabletemperature of 70°C (158°F) or above.

• Do not connect cables outdoors in wet weatherin order to prevent damage from condensationand to protect the insulation.

• All the cable ends must be provided with roundcrimp-on terminals and be securely wired.

• Ground the remote flowtube and the converterseparately (with grounding resistance of 100Ωor less)

• Cover each shield of the signal cable with vinyltube or vinyl tape to avoid contact between twoshields or between a shield and a case.

• In case of 24V power supply version, it comeswith a plug. Use this plug to cover the unusedwiring port when wiring the instrument with onlyone, four-core cable.

• Be sure to turn power off before opening thecover.

• Before turning the power on, tighten the coversecurely.

• Hazardous duty types must be wired inaccordance with specific requirement (and, incertain countries, legal regulations) in order topreserve the effectiveness of their explosionprotected features.

• The terminal box cover is locked by the specialscrew. In case of opening the terminal boxcover, use the hexagonal wrench attached.

• Be sur to lock the cover by the special screwusing the hexagonal wrench attached afterinstalling the cover.

Figure 4.2.2 Treatment of Dedicated Signal Cables

CAUTION

• As crimp terminals A, B, SA, SB and C havetheir own electrical potentials, securely insulatethem so as not to come in contact with oneanother.

• To prevent a shield from coming in contact withanother shield or the case, cover each shieldwith a vinyl tube or wrap it in vinyl tape.

NOTE

Conductors A and B carry the signal from theelectrodes, and C is at the potential of the liquid(signal common). Shields SA and SB are keptat the same potentials as the individual elec-trodes (these are actively driven shields.) This isdone to reduce the effect of the distributedcapacitance of the cable at long cable length.Note that, since the signals from the individualelectrodes are impedance converted inside the

converter, errors will result if they come incontact with any other component. Great caremust be taken in the cable end treatment.

(2) Excitation Cable/Power Cable/Output CableUse polyvinyl chloride insulated and sheathed controlcables (JIS C 3401) or polyvinyl chloride insulated andsheathed portable power cables (JIS C 3312) or theequivalent.

4.4.3 Precautions for Wiring of PowerSupply Cables

When connecting to the power supply, observe thepoints below. Failure to comply with these warningsmay result in an electric shock or damage to theinstrument.

WARNING

• Ensure that the power supply is OFF in order toprevent electric shocks.

• Ensure the protective grounding terminal isgrounded with a grounding resistance of 100Ωor less before turning the power on.

• Use insulating sleeve crimp terminals (for 4-mmscrews) for the power supply wiring and protec-tive grounding wiring.

• Install an external switch or circuit breaker as ameans to turn the powe off (capacitance; 15A,conforming to IEC947-1 and IEC947-3). Locatethis switch either near the instrument or in otherplaces facilitating easy operation. Affix a“Power Off Equipment” label to this externalswitch or circuit breaker.

4.4.5 Grounding

CAUTION

Be sure to connect the protective grounding ofthe AXFA14 with a cable of 2mm2 or larger crosssection in oder to avoid electrical shock to theoperators and maintenance engineers and toprevent the influence of external noise. Connectthe grounding wire to the mark (100 Ω orless).

IMPORTANT

When a lightning protector (option code: /A) isselected, use a grounding resistance of 10Ω orless.

• The protective grounding terminals are locatedon the inside and outside of the terminal area.Either terminal may be used.

• Use 600-V vinyl insulation wires as the groundingwires.

Connect the AXFA14 terminal to external instruments,giving attention to the following points.

· 4-20 mA DC Output

Figure 4.4.7 4-20 mA DC Output Connection

· Pulse Output

IMPORTANT

• As this is a transistor contact (isolated type),give attention to proper voltage and polaritywhen wiring.

• Do not apply a voltage larger than 30V DC or acurrent larger than 0.2A in order to preventdamage to the instrument.

• When input filter constant of the electroniccounter is large in relation to the pulse width,the signal will decrease and the count will notbe accurate.

• If the input impedance of the electronic counteris large, an induction noise from the powersupply may result in inaccurate counts. Use ashielded cable or sufficiently reduce the inputimpedance of the electronic counter within theelectromagnetic flowmeter pulse output specifi-cation range.

• The active pulse output (/EM) cannot be usedin conjunction with the standard pulse output.

• When the active pulse output (/EM) is selected,do not short-circuit the DO+ and DO– terminalsto avoid damaging the instrument.

• To avoid communication (BRAIN/ HART)failure, it is recommended to use the shieldcable.

NOTE

For pulse output from the DO terminals, param-eters must be set. Refer to “Chapter 6: Param-eter Description” in this manual.

IMPORTANT

Since this is an isolated transistor output, becareful of voltage and polarity when wiring. Donot apply a voltage larger than 30V DC or acurrent larger than 0.2A in order to preventdamage to the instrument.This output cannot switch an AC load. To switchan AC load, an intermediate relay must beinserted as shown in Figure 4.4.11.*The alarm output operates from open (normal)to closed (alarm occurrence) in the default value(as setup upon plant shipment). Changes canbe made via the parameter settings.

6. PARAMETER DESCRIPTION6.1 ParametersWith the exception of parameters that were specifiedby the customer upon ordering, all of the internalparameters will initially be set to default values.Actions such as the modification of display details canthen be carried out whenever necessary.

IMPORTANT

Make sure to keep the instrument’s power on atleast for 30 seconds after you set the param-eters. If you turn the power off immediately afterthe parameters are set, the settings will becanceled.

NOTE

In order to ensure that correct flow-rate data canbe acquired, it is crucial that the nominal size,flow-rate span, and meter factor of the combinedremote flowtube are set. In cases where aremote flowtube is ordered at the same time asthe AXFA14, or where the AXF integral flowme-ter is ordered, the nominal size and meter factorwill be set upon shipment from the manufactur-ing plant, and these will not require additionalsetting. If the AXFA14 is ordered separately, thedefault value will be set for the meter factor;accordingly, it will be necessary to change thissetting to the meter factor indicated on yourremote flowtube data plate. If a flow-rate spanwas specified upon ordering, this will be setbefore shipment. If this is not the case, how-ever, it will be necessary for the appropriatevalue to be set by the user.

6.4 Parameter Description(1) Menu B: Easy Setup itemsThose parameters with a high frequency of use havebeen grouped together in Easy Setup. All basicfunctions can be controlled using only the parametersfrom this block. Parameters from Menu B shareidentical names with those from other menus; however,modification of one such parameter will result in theother being automatically modified.

[B10: Language] Setting of parameter language→ This setting is linked with that of parameter H30.One of the following languages can be selected for useby the display unit. All Parameters, alarm messages etcare displayed in the selected language.

Data RangeEnglish, French, German, Italian, Japanese, Spanish

[B20: Flow Damping] Setting of the damping timeconstant→This setting is linked with that of parameter C11.The damping time constant should be modified tosuppress an output fluctuation or to change the re-sponse time. This time constant has an effect on analogoutput and on the display unit’s flow-rate display (i.e.,actual instantaneous flow rate, %, current value), andin addition, it also affects pulse output and totalization.However, when “No Damping” has been set for J24:T/P Damp Select, there will be no effect on pulseoutput or totalization. * Time constant: The time required for the output to

reach 63.2% from 0%.

[B21: Base Flow Unit] Selection of flow-rate units→ This setting is linked with that of parameter C40.This parameter selects the flow-rate units. (In case ofmass flow, the setting of density is also required.Refer to C46: Mass Flow Density for more details.)

[B22: Base Time Unit] Selection of time units→ This setting is linked with that of parameter C41.This parameter selects the time units; however, if“meter” has been selected in B21 (or C40) for theflow-rate units, “/seconds” is automatically set for thisparameter.

[B23: Flow Span] Setting of the flow span→ This setting is linked with that of parameter C42.The span can be set for the forward flow rate in therange 0 to 32,000 (although this does not include 0). Theunits set using B21/C40: Base Flow Unit and B22/C41: Base Time Unit will be displayed at this time.

NOTE

If the flow-rate units, time units, and flow-ratespan are specified upon ordering, these param-eters will be setup before shipment; however, ifthis is not the case, it will be necessary for theappropriate values to be set up by the user.

NOTE

Flow-rate span is the value for instantaneousflow rate that corresponds to a current output of20 mA. The following factors should be takeninto consideration when deciding on the flow-ratespan.• In the case of lines with large variations in flow

rate, the maximum flow-rate should be set. If aflow-rate in excess of the flow-rate span was tooccur, output would be possible up to an upperlimit of 108%, and beyond this, error wouldoccur. Note that the same applies to pulseoutput and totalization.

• In the case of lines that have a relatively stableflow-rate, a flow-rate span of 1.5 to 2.0 timeslarger than the normal flow-rate may be consid-ered suitable.

• The flow-rate to be adopted should - uponconversion to flow velocity - correspond to avalue within the range of 0.1 to 10 m/s. Theflow velocity can be confirmed using sizing dataor with parameter C44: Velocity Check, and inthe latter case, the value obtained when span isconverted to flow velocity will be displayed.

• Regardless of the position of the decimal point,the largest value that can be set on the displayunit is 32,000 (data range). Furthermore, it isnot possible to set a number of 4 or greater forthe highest-order digit. Similarly, if 3 is set forthis highest-order digit, it will not be possible toset a number of 2 or greater for the next digit tothe right, regardless of the position of thedecimal point.

Multiple ranges settingParameters from F30 to F41 are used with theautomatic multiple ranges and the multipleranges switching via an external status input.The followings will describe the setting methodfor each range.

The multiple ranges use the following parameters:[F30: Forward Span 2] Setting of the forward No2.range[F31: Forward Span 3] Setting of the forward No.3range[F32: Forward Span 4] Setting of the forward No.4range[F33: Reverse Span 1] Setting of the reverse No.1range[F34: Reverse Span 2] Setting of the reverse No.2range[F40: Auto Range Hys] Setting of the automaticmultiple ranges hysteresis width.[F41: Bi Direction Hys] Setting of the forward/reverse flow measurement hysteresis

Multiple Ranges Setting 1:Automatic multiple ranges switching·

· When the input exceeds 100% of the range,transition to the next range (up to four ranges)is carried out automatically. Furthermore, whenthe flow is in reverse, the reverse range isautomatically selected.

· Range switching can be confirmed according to thestatus of the DO and DIO status output terminals.Refer to Table 6.4.1: Status Output for AutomaticRange Switching for details of status output condi-tions for each range.

Status Output for Automatic Multiple RangesSwitchingOperations are performed in accordance with thefollowing table when the active mode has been set to“Closed (On) Act” using F22: DO Active Mode or“Closed/Short Act” using F23: DIO Active Mode.Operating patterns are reversed when the active modehas been set to “Open (Off) Act” using F22: DOActive Mode or “Open/Open Act” using F23: DIOActive Mode.

[J21: Rate Limit] Setting of the rate limit value· This parameter is used in situations where sudden

noise cannot be eliminated by increasing thedamping time constant.

· In situations where step signals or sudden noisesignals caused by slurry or the like are entered, thisparameter is used to set the standard for determiningwhether an input corresponds to a flow measurementor noise. Specifically, this determination is madeusing upper and lower rate limits and using the deadtime.

· Rate limit values are set using a percentage of thesmallest range. The range of deviation per onecalculation cycle should be input.

[J22: Dead Time] Setting of dead timeThis parameter sets the time for application of the ratelimit, and if a value of 0 is set, the rate limit functionwill be terminated.

Rate limit value:Determines the level for output fluctuation cutoff. For example, if this is set to 2%, noise above and below 2% will be eliminated as shown in the diagram.

Dead time (T0):This is to be determined using the output fluctuation width. If noise exceeds the dead time as shown in the diagram below, the dead time should be made longer.

· Signal processing method:A fixed upper and lower limit value is setup withrespect to the primary delay response value for theflow-rate value obtained during the previoussampling, and if the currently sampled flow rate isoutside these limits, then the corresponding limit isadopted as the current flow-rate value. In addition, ifsignals which breach the limits in the same directionoccur over multiple samples (i.e., within the deadtime), it is concluded that the corresponding signalis a flow-rate signal.

6.6 Precautions for theAXF Integral Flow-meter

Although the AXF integral flowmeter’s softwareconfigurations are the same as the AXFA14, care mustbe taken in setting the following parameters:

[C31: Nominal Size Unit] Setting of the nominalsize units[C32: Nominal Size] Setting of the nominal size[C21: Low MF] Setting of the low-frequency meterfactor[C22: High MF] Setting of the high-frequency meterfactor[C23: Low MF (EDF)] Setting of the low-frequencymeter factor for enhanced DF (i.e., enhanced dualfrequency excitation)[C24: High MF (EDF)] Setting of the high-frequencymeter factor for enhanced DF (i.e., enhanced dualfrequency excitation)

NOTE

The nominal size unit, nominal size and meterfactor have been properly set upon shipmentfrom the manufacturing plant. If you still have theoriginal configuration please do not change theseparameters.

NOTE

Setting the meter factor

F0623.EPS

Meter factor for the AXF integral flowmeter

(1) Confirm that the meter factor indicated onyour AXF integral flowmeter’s data plate hasbeen set to the parameters.

(2) The meter factors are crucial in ensuring thatthe electromotive force is correctly in propor-tion to the flow velocity and are determinedat the manufacturing plant by actual-flowcalibration.

NOTE

For the hardware configuration of the AXFintegral flowmeter, see the user’s manual of theAXF Integral Flowmeter [Hardware Edition] (IM01R20D01-01E).

8.1 Conditions of Communication Line8.1.1 Interconnection between AXFA14 and HART Communicator

The HART Communicator can interface with the AXFA14 from the control room, theAXFA14 site, or any other wiring termination point in the loop, provided there is a minimumload resistance of 230 Ω between the connection and the receiving instrument. To communi-cate, it must be connected in parallel with the AXFA14, and the connections must be non-polarized. Figure 8.1.1 illustrates the wiring connections for a direct interface at the AXFA14site. The HART Communicator can be used for remote access from any terminal strip as well.

9. ACTUAL OPERATION

9. ACTUAL OPERATIONAfter you have installed the flowtube into the processpiping, wired the input/output terminals, set up therequired parameters, and performed a pre-operationzero adjustment, the magnetic flowmeter should outputan accurate flow signal from its terminals as soon asflow of the fluid to be measured begins. This sectiondescribes zero adjustment and the correspondingprocedures.

9.1 Pre-operation ZeroAdjustment

Zero adjustment is carried out to ensure that the outputfor zero flow is 0% (i.e., 4 mA). Although adjustmentto zero is performed at the manufacturing plant prior toshipment, this procedure must be carried out onceagain following the installation of piping in order tomatch the magnetic flowmeter to its operating condi-tions.

This section describes the zero adjustment procedureusing display unit switches from the converter andusing the external status input; accordingly, one ofthese methods should be selected and implemented.

IMPORTANT

• Zero adjustment should be carried out beforeactual operation. Note that setting and updatefunctions cannot be carried out during thisprocedure (i.e., for approximately 30 seconds).

• Zero adjustment should only be carried outwhen the flowtube has been filled with fluid andthe fluid velocity is completely zero by closingthe valve.

9-2IM 01R20C02-01E-H

9. ACTUAL OPERATION

9.1.1 Zero Adjustment Using the infra red SwitchesThis section describes the procedure for zero adjustment using the display unit switches.(For more details regarding setting methods using these switches, refer to Chapter 5: BasicOperating Procedures.)

The parameters for zero adjustment are B50/M10: Auto Zero Exe (and either of thesecan be used to carry out this procedure). For more details regarding these parameters, referto Chapter 6: Parameter Description. The parameter M10 will be used in the followingdescription.

Once in Setting Mode, use the switch tomove the cursor to item M.

When the cursor has been moved to item M, touchthe switch to access Parameter Search Mode.

Touch the switch to access M10: AutoZero Exe.

Parameter Replacement Mode has been accessed inthis screen.

Touch the switch to move the cursor to“Execution”.

When the cursor has been moved to “Execution”,touch the switch to select the automatic zeroadjustment function.

In order to indicate that confirmation using the switch is requested, the entire display flashes

on and off. Touch the switch once again atthis time to fix selection of the automatic zeroadjustment function.

Auto zero adjustment function is being executed(about 30 seconds).

The system returns automatically to the Sub-itemSelection Screen. If the switch is now usedimmediately to access M10: Auto Zero Exe onceagain, “Execution” will be displayed. When theprocess has been completed, this will change to “NoExecution”.

9.1.2 Zero Adjustment via External Status InputThis section describes the procedure for zero adjustment via external status input. (Formore details regarding external status input, refer to Chapter 6: Parameter Description.)

CAUTION

In certain cases where the multiple range function is being used with other statusinputs, it may not be possible to perform settings for automatic zero adjustment.For more details, refer to the description of multiple ranges from Chapter 6:Parameter Description.

In order to carry out zero adjustment via external status input, it will be necessary to set“Ext Auto Zero (I)” using F21: DIO Function. The following describes the settingprocedure:

Once in Setting Mode, use the switch tomove the cursor to item F.

When the cursor has been moved to item F, touchthe switch to access Parameter Search Mode.

10.2 Setting of Switches10.2.1 Setting of Burnout SwitchThe burnout function sets the direction of currentoutput in situations where the CPU has becomedamaged. Upon shipment from the manufacturingplant, the burnout direction is set to High (i.e., 25 mA);however, in cases where the option specification code /C1 has been specified, the output direction will be setto Low (i.e., 0 mA).

Modification of the burnout direction must be carriedout using the setting switch from the amplifier’s CPUboard (i.e., Switch 1) (See Figure 10.2.1).

10.2.2 Setting of Write Protect SwitchBy setting the write protect function to “Protect” it ispossible to prevent the overwriting of parameters.Write protection can be carried out using either thehardware switch on the CPU board (i.e., Switch 2) orsoftware parameter settings. If either of these items isset to “Protect,” the overwriting of parameters will beprohibited.

NOTE

If the hardware switch is set to “Protect,” it willnot be possible to overwrite parameters; further-more, this condition will be maintained until theswitch is set to “Enable.”

START

Check for the presence of valve leakage.

• Confirm the flow tube grounding. • Confirm whether or not the

grounding wire is disconnected from the earth flange.

Recheck the fluid to be measured.

Particular care must be taken in the case of horizontal mounting. In order to ensure complete filling of the tube, either adjust the mounting position or switch to vertical mounting.

Install a defoaming device on the flowtube’s upstream side.

Replace the valve(s).

Completely ground the flowmeter (grounding resistance must be 100 or less).

• Ensure that the fluid’s conductivity changes as little as possible.

• Do not use the meter when fluid conductivity is less than 1 S/cm.

• Whenever possible, reduce the flow velocity to being in the vicinity of the lower conductivity limit.

• Remove dirt and scale of and near electrodes.

• Use a soft brush or cloth to perform scale removal, and make sure that the lining is not damaged.
