1. Introduction

We congratulate you on the decision to employ the eddyvisor in your factory. Withthis instrument you have acquired the most advanced eddy current testing deviceworking according to the PREVENTIVE MULTI-FREQUENCY TEST as well as thePREVENTIVE MULTI-FILTER TEST (PMFT). Successful implementation of a testpresupposes, in addition to a full command of the instrument settings, also a solidknowledge of the product to be tested, its material properties, of the errors likely tooccur and their underlying causes.

The tester must be conversant with the limitations and restrictions in errordetectability as well as with the efficiency of the equipment used and with its properfunction. It is the proper functioning that needs to be checked prior to every test andperiodically during operation in order to warrant reliable test results. If theserequirements are not satisfied, the result will be of questionable value.

Should you have any further questions or need our advice for an optimum solutionof your testing problem, please do not hesitate to contact us. Our after-sales serviceis ready to help you at any time.

Chapter "3. Short operating instructions" from page 3-1 is mainly intended to savethe users who are not constantly working with the eddyvisor the troublesomestudy of a detailed user manual.

As a new user of the eddyvisor you should simply try to perform a test with thisunit under the guidance of the "3. Short operating instructions" before going throughthe detailed user manual and the fine adjustment of all parameters. You will besurprised how quick you will learn to handle the eddyvisor.

Please read these concise operating instructions carefully in order to avoidoperating errors. We have tried hard to keep the instructions as short as possible inan effort not to burden you with unnecessary information.

1.1. What is an eddyvisor?

The eddyvisorS is an eddy current test instrument for Structure test using PMFTPreventive Multi-Frequency Test. This enables testing e.g. for material mix,hardness, case depth, material composition as well as material texture ofconductive materials.

The eddyvisorC is an eddy current test instrument for Crack detection usingPMFT Preventive Multi-Filter Test. This enables testing e.g. for surface-opencracks or disturbances of surface texture of conductive materials.



The eddyvisorSC combines both test methods (Structure & Crack test) in oneinstrument.

1.2. The principle of eddy current structure testing

When alternating current is sent through a transmitter coil, a magnetic field buildsup at the coil. If a conductive test specimen approaches the current-carrying coil, aneddy current is induced in the test specimen. This phenomenon is schematicallyillustrated in fig. 1.1.

Figure 1.1

The magnitude of the eddy current depends on the chemical composition (alloy) andon the structural condition (e.g. hardened). By changing the eddy current frequency,an electromagnetic "thumbprint" of the structural state is obtained in the coil system.This can be picked up by the instrument through the integrated receiver coil andevaluated.

An alteration in the structural state, in the alloy and the like attributable to a mix-upof material, a batch mix or faulty thermal treatment causes also the eddy currentsignal to change. The eddyvisorS testing device recognizes such changes andindicates deviations.

The eddyvisorS operates according to the method of PREVENTIVE MULTI-FREQUENCY TESTING (PMFT) developed by ibg. The merit of PREVENTIVEMULTI-FREQUENCY TESTING is seen in the high probability of detecting evenunknown flaws on account of the broad frequency band selected.

In contrast to other procedures, ibg uses low field strength values. This means thatonly low currents flow through the coils and that low permeabilities develop inferromagnetic materials (initial permeability).



This method affords the following advantages:

It operates at the higher penetration depth of the eddy current so that theinfluence exerted by the marginal layers is reduced.

The reproducibility of the measurements is guaranteed because no magneticalterations develop in the structure of the specimen.

Improved testing stability because no heat builds up in the specimen, theinstrument and in the coil.

The salient properties of PREVENTIVE MULTI-FREQUENCY TESTING (PMFT) arethe following:

Maximum testing reliability - even unknown flaws are identified without fail.

Only good parts must be presented to the instrument.

The generation of tolerance zones is extremely simple and made in a very shorttime.

1.3. Possibilities of eddy current structure test

Eddy current inspection can be applied to any type of material being conductiveeither electrically or magnetically. This holds good for all metallic materials.

The eddyvisorS takes care of all the fields of application summarily mentioned intable 1.1.

Table 1.1

Please note that the eddy current inspection procedure is not an absolutemeasuring method but rather a comparative approach. The hardness of parts canbe measured with the eddyvisorS inspection device to within 2-3 HRC withoutany problem. However, as is the case with all eddy current tests, the inspection is



based on YES/NO answers. The eddy current testing instrument does recognizedeviations from existing tolerance zones, but cannot reveal the causes responsiblefor them. In order to obtain precise information on why the specimens wereclassified as not being in order, yet other testing procedures such as hardness testand metallographic studies must be employed to confirm the findings of the eddycurrent device.



2. General information

The eddyvisor eddy current inspection device is multiprocessor-controlled. Theentire control software is configured hierarchically, so the selectable submenusautomatically result from each main menu. The eddyvisor is operated via a so-called soft key control system which enables the user to handle the device with arestricted number of keys.

These operating instructions have been arranged so that each step of operation isexplained in chronological order. All you need to do is to execute the instructionsstep by step as indicated. While proceeding in this manner, you are guided throughthe complete software.

Hint

The [?]-is auxiliaryand serves to indicate a context-related help at any time.

This means that the help needed is offered at any point of thesoftware.

The key combinations to be actuated by the user are written inbold capital letters throughout the User Manual.

2.1. Selection of structure test coils

Selection of the proper test coils and probes is of decisive importance for the testresult. In addition to a set of standard coils and probes, special coils adapted to thejob are available. The selection of suitable coils determine the type of job and theshape of the specimen. Here the following criteria should be considered:

What is the job like?e.g. measurement of the case depth of shafts

Which coil should be used?The suitable coil or probe can be taken from table 2.1.

Table 2.1

Our standard coils are classified by frequency ranges. Whereas the frequencyrange of the encircling coils is directly indicated on the name plate, the probes arecoded as follows:

1 ring 25 Hz to 10 kHz2 rings 250 Hz to 50 kHz3 rings 5 kHz to 250 kHz

As far as encircling coils are concerned, a filling degree of less than 60 % shouldnot be selected as otherwise the measuring signals become too small and thedifferences, say, in the case depth are no longer recognized distinctly. When usingencircling coils, a second coil is required for compensation. This coil must feature a



firmly (!!!) mounted compensation part. Removing or shifting the compensation partleads to wrong test results. The compensation part has no comparing functiondesigned to distinguish the OK-parts from the NotGood-parts.

The basic design of the standard encircling coils is displayed in Fig. 2.1. Each coilcontains a transmitter and receiver winding. The receiver winding should always bearranged as close as possible to the area to be measured. It is very easy to find outon what side the receiver or transmitter windings are located. Just take an encirclingcoil and read the name plate. If you can read this plate and when the coil plug is onthe left of you, the receiver winding is below and the transmitter winding is above inthe coil.

2.2. Creation of optimum test conditions

Be sure to pay attention to the following points when carrying out a testing job.Carefully read the following hints. Disregarding them is likely to lead to faultymeasurements. The eddy current procedure is no absolute method.

The following parameters may cause the results to scatter:

Inhomogeneities in material

Dimensional tolerances in the specimen

Dimensional tolerances in coil or probe positioning



Variations in temperature (structure test)

For optimum results please pay attention to the following points:

Make sure that the parts used for Reference Data really comply with the desiredspecifications.

Show at least 5 OK parts to the instrument as Reference Dataat least 10 OK parts when structure testing.

Select reasonable tolerance sizes.To avoid the risk of undesirable pseudo rejects.

Do random checks during testing with OK and NG parts.

Lock the instrument with the keyswitch to avoid unwanted access.

Read the operating manual before initial operation.

Provide constant and reproducible test conditions.

Avoid interferences near the coil resp. probe such as current impulses, fluxsetups active during the measurement, electric welding and other magnetic orelectric interference fields.

In addition for structure test:

Different batches should be tested separately.The best results are obtained if for each material batch an own part type (withown reference data) is used.

Please see to it that the test parts have constant test temperature.

Please see to it that no metallic parts, which are not marked for testing, arelocated near the test coils.

Carry out the test on a wooden table, if possible. Even steel girders underneath awooden board are likely to affect the test results.

The following factors may adversely affect the measurement directly:

Positioning of the specimen in the coil resp. in relation to the probe (distance).

Dimensional tolerances of the specimens.

Structure test: variation in batches or differences in temperature betweencalibration part and test part.



Use of coils resp. probes with a wrong frequency range.

Lift-off effect due to dust and dirt.

Edge effect caused by measuring near edge of part

2.3. Wiring

Prior to putting the eddyvisor into operation, all cables must be connected and allconnections to be checked.

WARNING

Please take care that all cables are plugged and screwed tightbefore the power switch is turned on.

The instrument must be grounded properly (PE connector of themains plug or grounding screw on the instrument housing, seedrawing of the back side of the instrument below). Otherwise,voltage may constitute on the housing. If the instrument is not

grounded properly, the safety standard protective ground are notobeyed. Furthermore, quality of testing is impaired so that

optimum test results cannot be achieved.

Also ensure that all plugs are firmly connected and screwed tight.

If plugs are inserted after connection of the eddyvisor thevarious components are likely to be damaged!

The eddyvisor consists of the operating unit eddyvisorHMI and the measuringunit for structure resp. crack test eddyvisorMSC (refer to "9. Glossary"). Both unitscommunicate via USB interface.

Both units are connected to one unit as eddyvisor desktop instrument. Powersupply is effected via the measuring unit. USB coupling of the single parts is doneinternally without using the USB jack of the measuring unit.

Operating and measuring unit are supplied separately when using the eddyvisor

in a test system. Both units have to be supplied with line voltage. USB coupling ofthe single parts is done via one of the protected lower USB jacks of the operatingunit and the USB jack of the measuring unit.

The eddyvisorS operates on the ibg-developed principle of PREVENTIVEMULTI-FREQUENCY TESTING (PMFT). After the measurement has beentriggered, the test frequencies are applied successively to the coil system, startingat the lowest test frequency. At each test frequency the response of the specimento the coil system is recorded and the electric voltage vector is broken down into itsX and Y components and stored.

Upon completion of the test, the values stored are, depending on the operatingmode, either compared with the tolerance zones (mode SORTING) or assigned tothe material data (mode RECORDING O.K. PARTS).

STARTx (start pulse)

settling delay

BUSY-S(structure test runs)OKx (sort output Gut)

ENDx (end of measuring)



Measurement starts with the "START-Signal":

Measurements are started with the START-signal and need a certain time (BUSY-S-signal). A measurement can only be triggered in mode REFERENCE DATA orPREVENTIVE MULTI-FREQUENCY TEST.

Settling delay:

After starting a test, but before the test proper begins, the operator may select anadjustable settling delay. This delay allows the specimen to "settle inside the testcoil", so the test will only be started as soon as the part has taken up its finalposition in the coil.

The "BUSY-S-signal":

If the test unit functions in one of the two operating modes REFERENCE DATA orPREVENTIVE MULTI-FREQUENCY TEST the BUSY-S-signal (BUSY, structuretest) will appear immediately following the START-signal. The settling delay startsrunning and upon expiration the test proper commences at the first frequency.

If the start of the following location is set to AFTER the settling delay of this location is immediately started, the BUSY-S-signal remains active.

If it concerns, however, the last channel within a test block the BUSY-S-signaldisappears. Disappearing of the BUSY-S-signal means that the eddyvisorS isready to start a new measurement.

The sorting decision with the "OK-i-signal":

After testing a location at all frequencies the sorting decision is made andtransmitted to the sort outputs (OK-i-signal, NOK-i-signal). In mode REFERENCEDATA no sort signal appears.

The sum sorting decision with the "OK-S-" and "NOK-S-signal":

After testing all locations of one station the sorting decision for the station is madeand transmitted to the sort output (OK-S-signal and NOK-S-signal). For this, theformation of the sum signal OK-S must be set. In mode REFERENCE DATA no sortsignal appears.

The END-i-signal:

After testing a location at all test frequencies the allocated END-i-signal appears.



The sum signal END-S:

After testing all locations of one station the sum signal for the station is made andtransmitted to e.g. the output END-S. For this, the formation of the sum signal END-S must be set.



3. Short operating instructions

3.1. Structure test

These concise operating instructions are intended to show you, that theeddyvisorS enables you to obtain test results in a short time, whenever projectsare available. A standard project 'screw test' (DEMO mode) is used here. It isadjustable in the menu SETUP, PROJECT & LANGUAGE.

Below are the sequence of steps to be executed:

(a) The probe resp. the coils are directly connected to the measuring unit ofthe eddyvisorS, coil board VCONS in slot 1 and jack A. Usingencircling coils: one part is put into the compensation coil(s). Using self-compensated coils or probes: no compensation part needed.

(b) If operating and measuring unit are separate they have to be connectedvia a USB-cable.

(c) Connect eddyvisorS to mains supply. If operating and measuring unitare separate both units must be supplied with mains voltage.

(d) Prepare at least 10 (better some more) OK parts (as reference).

(e) The characteristic eddy current data are recorded by "showing" the knownOK-parts. The eddyvisorS automatically forms tolerance zones.

(f) The specimens are tested by comparing their eddy current characteristicswith the tolerance zones formed by the material data and sorting based onGood (OK) and NotGood (NOK) criteria.

Now proceed step by step as indicated in the short operating instructions.

The standard configuration of the eddyvisorS includes already a testconfiguration. This standard configuration is accessible via menu SETUP,PROJECT & LANGUAGE, STANDARD PROJECT ... (DEMO MODE). Any changesto this demo project will get lost when switching off the eddyvisorS or leaving thedemo mode.

In the upper part of the station window each location has a bar with parameters. Ifthere are more locations than can be displayed a scroll bar is shown. Below thereare sum information on the station and the amount of locations.

Coil resp. probe



In general, a pair of coils is used for structure testing, one test coil and the relatingcompensation coil.

Crack detection uses probe w/o or with lift-off compensation.

The pair of coils / the probe is connected to the VCONS / VCONC. Connection plugis shown in format:

VCONS-slot (1 - 4), connector VCONS (A or B), pair of coil (1 or 2)

Example: coil 1A2 means VCONS in slot 1, connector A, pair of coil 1.

The coil is set in the same way for all locations of a station in the location barindividually or via the key "coil". When selecting a coil, an overview appearsshowing all possible coil connections. Touching same key again closes theoverview. Touching a marked coil proposal in the overview takes it.

Coil monitoring is set either "ACTIVE" or "not active". If coil monitoring is activethe test coils are monitored for short-circuit or break. In case of any failure testing isstopped and a failure message appears on the screen.

Start Signal

Start of reference data recording or Preventive Multi-Frequency Test is triggered bya logical start signal. The logical start signal of a location knows different startmodes:

START 1..32Triggering of start via rising edge at one input of a VCONI-board. It isrecommended to use START-i signals of standard pin assignment only.

Conti (structure test only)Continuous triggering - the start signal is triggered automatically in shortintervals (approx. 20 msec.). Application: triggering of the first test of a stationwhich permanently tests.

AFTER, symbol (structure test only) Automatic start trigger after testing of the previous location. Application:triggering of the succeeding measuring in a coil head with several locations.

AutoStart (structure test only)Automatic triggering when a test part approaches the test coil. AutoStartfunction has to be set individually in menu "Frequencies & Locations.

External, Ext. (structure test only)Use of an external START-key which is connected to the coil plug e.g. structuretest probes with integrated START-key.



Manual, short Manu (structure test only)Triggering of start only by START-key on the eddyvisor. The START-key ofthe eddyvisor may be used always for alternative triggering of a test unlesslocked by the key switch.

Method of start is set individually in the location bar or via the superset Start-keylogical Input for location 2 or higher. When selected an overview of the methodof start appears, pressing again closes the overview. Pressing a method of starttakes it.

Sort signal

During Preventive Multi-Frequency Test an OK-i signal (OK-1..32 resp. OK-S) andNOK-i signal (NOK-1..32 resp. NOK-S) is created after the sorting decision of oneor all locations. The sum signal "Result LOCATION 1-" indicates that all locationsare OK.

The logical signals are assigned to a pin in menu "In and outputs". Description is asfollows:

VCONI-slot (3,6,7), connector on VCONI (A or B), pin (1..37)

Example: 3A11 means VCONI in slot 3, connector A, pin 11.

If several outputs are assigned to one signal only one pin is given. It isrecommended to use signals of the standard pin assignment only.

The signal used is set for all locations individually in the location bar or via thesuperset key sort signal "logical Output". The sum signal is determined in the bar"result LOCATION 1-". When selected an overview of all possible sort signalsappears. Touching again closes the overview. Pressing a sort signal in the overviewtakes it. The symbol "---" removes the assignment.

The time of sort signals is set individually for each location or via the superset keysort signal "Time" for all locations the same. Duration of sum signal is set in thebar "result LOCATION 1-". When selecting a menu appears with the followingpossibilities:

Arrow keys and allow to set a duration between 10 ms and 1,000 msec.

SYNC_0the sort signals disappear when start trigger (the start signal) disappears orwhen the station is stopped.



SYNC_1the sort signals disappear when the next start trigger (the next start signal)arrives or when stopping the station.

SYNC_2the sort signals disappear just before the next sorting decision or when stoppingthe station. Thus a maximum duration of sort impulse length is achieved.

End Signal

After measuring of one resp. all locations, an END-i signal (END-1..32 resp. END-S)may be created. The signal used is set individually in the location bar or via thesuperset key end signal "logical Output" for all locations the same. Whenselecting an overview appears of all possible end signal. Touching again closes theoverview. Pressing an end signal in the overview takes it. The symbol "---" removesthe assignment.

The time of end signal is set individually for each location or via the superset keyend signal "Time" for all locations the same. The duration of sum signal is set inthe bar "result LOCATION 1-". When selecting a small menu appears to set:

arrow keys and allow to set a duration between 10 ms and 1,000 msec.

Monitor sorting gate is set either ACTIVE or not active. If active, then:

- connect a sensor at input GatePos-i which is allowed to give a +24V-signalonly when sorting gate is in NOK position.There is a direct assignment between the sum signals END-i from resultLOCATION 1-... and GatePos-i: At END_1, GatePos_1 is used, at END_2,GatePos_2 follows a.s.o.

- the sum sort signal OK-i from result LOCATION 1-... is supplied to control asorting gate.

- the sum end signal END-i from result LOCATION 1-... is supplied to control astopper and in case of NOK-parts delayed as long as the input "GatePos-i"gives a +24V-signal. If delay is more than 1 second a failure message isgenerated and the station stopped.

If monitor sorting gate is set to "not active" monitoring is off.

4.3.3. Inputs and Outputs

The assignment of internal logical signals of the eddyvisor (Start-1, GatePos-S,etc.) to the physical inputs and outputs of the VCONI takes place.



It is set in test assembly which logical signals are really used. In addition, there aresignals which are always present (e.g. StatActive-1).

It is recommended to work with the standard assignment and to do individualsettings only as an exception.

The inputs and outputs work with 24Vdc-Logik and may be directly connected withswitches, sensors (PNP-type, +24V switching) resp. sorting gates and other loadconsumers. Control of the eddyvisor via a PLC is feasible as well.

In order to increase the current load capacity of the outputs several output signals ofone VCONI may be connected with the same logical signal and switched in parallel.

4.3.3.1. Selection of VCONI

All available connectors are sorted according to the slot of the VCONI in the upperline and connector designator A or B; they may be selected by this identification,built of slot number and connector designator. Possible slots of the VCONI are slot3 in desktop instrument model, slots 6 and 7 in switchboard integration model.

4.3.3.2. Monitor inputs, force outputs manually

All input signals are asked every approx. 200 msec. and displayed. "ON" means+24Vdc input voltage. "OFF" means no input voltage.

All outputs may be operated manually to check electrical wiring and function.

Remark:When entering menu all stations must be stopped. Already started measurementsare finished and may be looked at, only then the outputs may be switched manuallyand the set function of inputs and outputs is unassigned until leaving the menu.

Pressing the key "Force Outputs (manual)" releases the outputs for manualoperation after a safety request. The name of the key changes to "DeforceOutputs.

Attention:If the outputs are manually operated this may affect any connected instruments! Ifseveral outputs of a VCONI are switched in parallel in order to increase current loadcapacity, consider this when manual switching the outputs, danger of short circuit,however, does not exist as the outputs of the VCONI are pure +24Vdc-driver (High-Side Driver).

The released outputs appear as key with name "OFF" for 0V resp. "ON" for +24Vdc.Pressing the key changes the condition of the key and the output. When there is novoltage at the corresponding pin of the connector, the voltage supply of the VCONI-



board has to be checked: The bridge connector has to be put for supply frominternal voltage source or the VCONI has to be supplied externally with +24Vdc.

4.3.3.3. Allow Signal Assignment

Each logical signal can be assigned to a physical input resp. output via the menu"Allow Signal Assignment". Logical input signals may be assigned only to onephysical input. Logical output signals may be assigned to any physical outputs. Afterpressing the key, a safety request appears and the name of the key changes to"Quit Signal Assignment".

It is recommended to work with the standard assignment and to choose otherproposals only as an exception. In very special cases only, an individual setting isnecessary.

Modified assignments of signals are displayed in blue colour. Pressing the key"Discard changes" restores the previous assignments and pressing "Savesettings" takes any changes. When leaving the menu a safety request asks if totake of discard assignments.

Standard Signal assignment

A standard assignment of signals for each constellation of instrument isrecommended. Pressing this key restores this constellation.

Show Proposal

A menu shows different pre-defined connector assignments. Should the standardassignment not cover the case of application, other typical assignments are givenhere. The text right beside the selection field informs on the planned application.Touching the names displays the new assignment with blue changes. Selection hasto be confirmed with key "Load Assignment" or leave the menu with key "DiscardProposal". An overview of all proposals is given in chapter 6.3.1. Proposal forSignal Assignment.

Unassign all Pins

All assignments between logical signals and physical inputs and outputs on thisconnector are unassigned and marked with "---".
