Display version,signal converter IFC 090—/D • When powered,the display shows in succession: START UP and READY. This is followed by display of the current flow rate and/or the current totalizer count on either a continuous or alternating basis, depending on the setting under Fct. 1.04. • Refer to Sect.4 and 5 for operator control of the"display version". 3/1 Factory settings 3.2 All operating data are factory set according to your order specifications. If you have not made any particular specifications at the time of ordering,the instruments will be delivered with the standard parameters and functions listed in the Table below. To facilitate easy and rapid initial start-up, current output and pulse output are set to process flow measurement in"2 flow directions", so that the current flowrate is displayed and the volumetric flow counted independent of the flow direction. On instruments equipped with a display, measured values may possibly be shown with a"—"sign. This factory setting for the current and pulse outputs may possibly lead to measuring errors, particularly in the case of volume flow counting: for example, if pumps are switched off and a"backflow"occurs which is not within the range of the low-flow cutoff(SMU), or if separate displays and counts are required for both flow directions.

The following HART features are supported by the IFC 090 signal converter: • point-to-point connection • multidrop(up to 15 HART devices) The burst mode is not normally used and is therefore not supported. Further information about HART is available from the HART Communication Foundation, of which Krohne is a member. Electrical connection HART connection active HART connection passive I+ I I1 I+ I Il 4 mA to next to HART communicator HART device 10 or smart converter power supply unit U to HART communicator or smart converter Factory setting for the point-to-point mode with HART • In Menu 1.05, the"FUNCTY'parameter must be set to"1 DIR". or"2 DIR.". • IMPORTANT: In Menu 1.05,the"RANGE I"parameter must be set to"4-20 mX, or, in the case of variable setting, the value for"I oi" must be at least 4 mA. • In Menu 3.09, the"COM1" parameter must be set to"HART"and the"ADDRESS" parameter to"0". • The current output may be operated in the active or passive mode. Factory setting for the multidrop mode with HART • In Menu 1.05, the"FUNCTY'parameter must be set to"OFF". • In Menu 3.09, the"COMV parameter must beset to"HART"and the"ADDRESS" parameter to a value of 1-15". This address may only beset for one device in the HART multidrop network. • IMPORTANT: the current output may only be operated in the passive mode. 6/5 Minimum load impedance A minimum load impedance of 250 0 is required to enable the HART signals to be modulated on the current output. Series-connect an appropriate resistor if the devices located in the current output circuit should not attain this value. It will then be possible via the minimum load impedance e.g.to connect the HART communicator or smart converter in parallel without interrupting the current output. Please note that the load impedance should not exceed a maximum of 500 Q. HART operating tools/DID The IFC 090 can be operated either via its local operator interface or by means of the HART communicator or the CONFIG program. Both operating tools are available from KROHNE. Operator control by means of the HART communicator requires a device description (DID)which we can load for you into the communicator.We can, of course, also load the DDs of all manufacturers who have filed their DDs with the HART Communication Foundation. If you wish to use the IFC 090 in your operating tool,for example, please ask for the description of the HART command used so that you can address the complete IFC 090 functionality via HART. In the near future we shall also be supporting the ASM tool from Rosemount and the SIPROM tool from Siemens. Power supply units/isolation switching amplifiers You will need an appropriate power supply unit if the current output is to operate in the passive mode. Please ensure that this power supply unit is also suitable for HART communication. This applies equally to isolation switching amplifiers that are sometimes used in the active mode.

Measurement is based on Faraday's law of induction, according to which a voltage is induced in an electrically conductive body which passes through a magnetic field. The following expression is applicable to the voltage.: U = K x B x V x D where: U = induced voltage K = an instrument constant / B = magnetic field strength v = mean velocity D = pipe diameter Thus the induced voltage is proportional to the mean flow velocity,when the field strength is constant. B � ' Inside the electromagnetic flowmeter,the fluid passes through a magnetic field applied perpendicular to the direction of flow.An electric voltage is induced by the •/ movement of the fluid (which must have a minimum electrical conductivity).This is proportional to the mean flow velocity and thus to the volume of flow.The induced voltage signal is picked up by two electrodes which are in conductive contact with the fluid and transmitted to a signal converter for a standardized output signal. This method of measurement offers the following advantages: 1. No pressure loss through pipe constriction or protruding parts. 2. Since the magnetic field passes through the entire flow area,the signal represents a mean value over the pipe cross-section;therefore, only relatively short straight inlet pipes 5 x DN from the electrode axis are required upstream of the primary head. 3. Only the pipe liner and the electrodes are in contact with the fluid. 4. Already the original signal produced is an electrical voltage which is an exact linear function of the mean flow velocity. 5. Measurement is independent of the flow profile and other properties of the fluid. The magnetic field of the primary head is generated by a square wave current fed from signal converter to the field coils. This field current alternates between positive and negative values.Alternate positive and negative flowrate-proportional signal voltages are generated at the same frequency by the effect of the magnetic field,which is proportional to the current.The positive and negative voltages at the primary head electrodes are subtracted from one another in the signal converter. Subtraction always takes place when the field current has reached its stationary value, so that constant interference voltages or external or fault voltages changing slowly in relation to the measuring cycle are suppressed. Power line interference voltages coupled in the primary head or in the connecting cables are similarly suppressed. 11/1 12 Block diagram-signal converter 1 Input amplifier • overdrive-proof signal processing, processes flow peaks up to 20 m/s(65 ft/s)and more rapidly and accurately • digital signal processing and sequence control • patented, high-resolution A/D converter, digitally controlled and monitored • high signal-to-noise ratio through low-loss field power supply with high frequencies and currents 2 Field power supply • the low-loss field power supply generates the pulsed, electronically controlled DC current for the magnetic coils of the primary head • The high field current ensures a high signal level 3 Current output • galvanically isolated from all other groups • converts the digital output signal from the ccP 3 microprocessor into a proportional current 4 Binary outputs and/or inputs • galvanically isolated from other groups • selectable input/output combinations • pulse output(131), passive FET optocouplers allow connection of electronic and electromechanical totalizers • status output(132)for limit value, error identification, or flow direction in forward/reverse flow mode(F/R)or measuring range identification in BA mode • both outputs can also be used as control inputs 5 Display/operator control unit(option, D Version) • large-size illuminated LC display • 3 keys for operator control of the signal converter • connection to the internal IMoCom bus • unit can be retrofitted to basic devices(B Version) 6 IMoCom bus plug connector for connection of external control and test devices such as: • adapter and CONFIG software for operation via MS-DOS PC 7 O BeX (D EEPROM 2 EEPROM 1 EEPROM 7 1 2 A NP 1 pP 3 3 D li internal WoCotn-Bus LC-Display NP 2 (Option) O R1 • B 2 I}- 12/1 Index Part E Keyword Section No. Fct.No. Keyword Section No. Fct.No. A F Abbreviations 1.3.2,1.3.4, F=forward flow 4.4,5.3,5.14 1.04-1.07 2.1,4.4 F1,F2=fuses 8.1,8.5 Accuracies 10.3 Factory settings 3.2 ADC=analog-digital converter 4.5,12 Fatal error 4.5 Ambient temperature 10.4 FE=functional ground 1.2,1.3.3,1.3.5 Application 5.19 3.06 Field power supply 5.12,10.4,12 3.02 Automatic range change(BA) 4.4,5.18 1.06,1.07 Flow -pulsating 6.4 3.06 B -rapid changes 6.5 131/132 outputlinput terminals 2.1,2.6,5.16 3.07(1.06,1.07) Flow direction 4.4,5.1,5.14 3.02 BA=automatic range change 4.4,5.18 1.06,1.07 Flowrate,rapid changes 6.5 Block diagram IFC 090 12 Flow rate(Q) 4.4,5.1 3.02 B version(basic) 4,6.2,8.4,10.4 Flow velocity v 4.4,5.1 3.02 Frequency(pulse output) C -Finax 5.7 1.06,3.07 C=control input 2.5,2.6,5.9 1.06,1.07,3.07 -Fmin 5.7 1.06,3.07 Cable length 1.3.4 Frequency output, Changeover,power supply 8.1 see pulse output P 2.3,5.7 1.06,3.07 Characteristics of outputs 5.15 Full-scale range Qtpp% 4.4,5.1,5.14 1.01,3.02 Clearing error messages 4.6 Function(s) 4.4 Coding for entry into Function of keys 4.1-4.3 setting level 5.11 3.04 Functional checks 7.1 et seq.
