3.1 Power-on and measurement

•

Before powering the system, please check that it has been correctly installed according to Sect. 1 and 2.

•

The flowmeter is delivered ready for operational use. All operating data have been factory set in accordance with your specifications.

Please refer to Sect. 3.2 “factory settings”.

•

Power the unit, and the flowmeter will immediately start process flow measurement.

•

Refer to Sect. 4 and 5 for operator control.

3.2 Factory setting

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. The 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.

To avoid faulty measurements, therefore, it may be necessary to change the factory setting of some or all of the following functions: – low-flow cutoff SMU, Fct. 1.03, Sect. 5.3 – display, Fct. 1.04, Sect. 5.4 – current output I, Fct. 1.05, Sect. 5.6 – pulse output P, Fct. 1.06, Sect. 5.7

Only part of the totalizer count is shown in the display because it is not possible to output a 14-digit number. Unit and format of the display are freely selectable, see Fct. 1.04, subfunction “totalizer” and Sect. 5.5. This determines which part of the count is to be displayed.

6.1 IFC 210 E – EEx for primary heads in hazardous areas

6.1.1 General

The following notes and directions contain only the data relevant to explosion protection. The technical details given in the Installation and Operating Instructions for the non-hazardous-duty version apply unchanged unless excluded or superseded by these directions.

In compliance with European Directive 94/9/EC (ATEX 100a), signal converters of the IFC 210E – EEx series are, in conformity with European Standards EN 50xxx, certified as associated electrical apparatus for supplying intrinsically safe equipment in hazardous areas by the Physikalisch – Technische Bundesanstalt (PTB) under PTB 00 ATEX 2026 X (see Sect. 13).

Important, please note!

•

Observe the directions and regulations and the electrical data specified in the

EC type test certificate.

•

In addition to the regulations for heavy-current installations (VDE 0100), pay particular attention to the requirements specified in

equipment in hazardous areas”

6.1.2 Electrical connection

The signal converter must be installed outside the hazardous area. If used inside the hazardous area, type IFC 210E- EEx signal converters need to have additional type of protection (e. g. flameproof enclosure “d”).

The electrical connection of all circuits leading into the device is carried out using plug-in connectors in conformity with DIN 41612, Style F. Type IFC 210E –EEx signal converters are delivered with associated socket connectors with soldering tags. Operation is only permitted with these socket connectors.

To ensure that the thread measure is min. 50 mm between the connections of the intrinsically safe electrode circuit and those of the non-intrinsically safe circuits, all live connections on socket connectors XA, XC, XD need to be insulated with shrinkdown sleeves. In this connection, nonintrinsically safe circuits of adjacent subassemblies will also need to be taken into consideration.

Both generation of the ungrounded intrinsically safe electrode circuit and also fuse-protection of the field current circuit by fusible cutouts are integral components of the IFC 210E-EEx signal converter.

The connections for the intrinsically safe electrode circuit, including the shield connections, are safety-separated up to a peak value of 375 V from the connections for supply power, for the inputs/outputs and for the field current circuit, and are metallically separated from the housing (PE/PA).

For connection of the intrinsically safe electrode circuit, including shield connections, to the primary head, please refer to Point 12 in EN 60079-14.

Connect the non-intrinsically safe field current circuit to the primary head in keeping with the requirements specified in Point 9 of EN 60079-14.

The non-intrinsically safe input and output circuits may only be routed into the hazardous area taking relevant measures into account in accordance with EN 60079-14.

Important, please note!

•

All unused cores and shield ends of the power cables to be carefully

insulated from each other and from ground.

•

All shields to be joined to the shield terminals by the shortest route.

•

Undocumented terminals of all connectors to be left unused.

•

Please take note of details given in Sect. 1.3.3 and 1.3.5.

Rated insulation levels The insulation of IFC 210 E - EEx signal converters is dimensioned in conformity with VDE 0110/IEC 664 and takes into account the following ratings:

- overvoltage category for the power line circuit: III

- overvoltage category for the signalling circuits: II

- insulation contamination level: 2

connection of a safety conductor (PE) is not required.

•

Equipotential bonding

Independent of the type of power supply, IFC 210 E – EEx signal converters must be

incorporated in the PA equipotential bonding system. To achieve equipotential

bonding, terminals d14, d16, d18, d20 must be connected to the appropriate ground

potential of the hazardous area.

IFC 210E-EEx is ungrounded in the electrode circuit, but the primary head is not!

For that reason, equipotential bonding is required in the entire run of the intrinsically

safe cable!

Cancellation of equipotential bonding is only permitted when the device is

disconnected from supply.

6.1.4 Fuse protection of the field power circuit

The field power circuit is fuse-protected in the IFC 210E –EEx signal converter by two TR5 fusible links on the amplifier board (ADC/FSV), see Fig. A in Sect. 8.4. Before starting up the system, check that both nominal fuse values are consistent with the maximum allowable nominal value specified for the primary head.

6.6 Stable signal outputs when measuring tube empty

Output signals can be stabilized to values as for “zero” flow to prevent random output signals when the measuring tube is empty.

- Display: 0

- Current output: 0 or 4 mA, see setting in Fct. 1.05

- Pulse output: no pulses (= 0 Hz), see setting in Fct. 1.06 Precondition:

- Homogeneous liquid products, free of solids and gasses an do not tend to electrical or catalytic reactions.

LA / S3 Empty Tube indication LA / S2 Empty Tube stabilization

LA / S3 actively detects an empty measuring tube and switches outputs and display to “0“ flow. When the measuring tube is empty, resistance between the electrodes becomes very high. A low current flows through the

-15 V at the one electrode (the other is connected to 0 V, chassis) via the high-resistance resistor and overdrives the instrumentation amplifier and then the A/D converter. This overdriving is evaluated.

Important, please note!

•

Observe the directions and regulations and the electrical data specified in the

EC type test certificate.

In addition to the regulations for heavy-current installations (VDE 0100), pay particular attention to the requirements specified in EN 60079-14 “Electrical equipment in hazardous areas”.

steady display at “0“ flow LA / S2 should be used when problems are encountered with LA / S3, e.g. due to electrolysis effects. Display is then particularly unsteady. At “0“ flow, the electrodes are connected to 0 V (chassis) via highresistance resistors.

LA / S4 electrode cleaning and Empty Tube stabilization

LA / S4 prevents any deposits of high-resistance layers on the electrodes (e.g. fat from very creamy milk) and effects stabilization similar to the LA / S2. For this purpose, the electrodes are connected to –15 V via highresistance resistors.

The flowmeter is designed for electrically conductive fluids. 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 × B × v × D K an instrument constant

B magnetic field strength v mean velocity D pipe diameter

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 is 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.
