3HardwareProduct Description

3 Product Description3.1 Hardware

The DUV10A diagnostic unit evaluates vibration signals using frequency analysismethods. A micromechanical acceleration sensor is used in the unit. Data can berecorded, processed and evaluated decentrally without any expert knowledge.

3.2 Continuous monitoring

The DUV10A diagnostic unit is suitable for early recognition of rolling element bearingdamage or unbalance. The continuous monitoring function offers a reliable and cost-effective solution compared to intermittent methods.

The DUV10A unit can be used to monitor up to 5 different objects or 20 frequencies. Arolling element bearing or a shaft is defined as an object, for example.

The DUV10A diagnostic unit enables immediate, permanent vibration monitoring.

3.3 Theory of operation

3.3.1 Brief description

The structure-borne noise is recorded and the frequency spectrum calculated to evalu-ate the condition of the rolling element bearings, unbalance in the unit etc. The conditioncan be read off directly and is visualized using binary switching outputs.

The switching signal can be transmitted via unshielded cables. The unit can also be con-nected to a bus system.

3 heory of operationroduct Description

3.3.2 Detailed description

• The DUV10A diagnostic unit continuously records the vibration acceleration of a non-rotating machine surface (32,000 values/second) and calculates the amplitudes ofdamage frequencies (rolling element bearing: inner ring, outer ring and rolling ele-ment) of up to 5 different diagnosis objects comprising a maximum of 20 individualfrequencies. The rolling element bearings or diagnosis objects to be monitored aredefined using PC software. They are then transferred as parameter sets to the sen-sor via an RS-232 interface. The condition of the rolling element bearing is then eval-uated and monitored relative to the teach-in value (reference value).

3Theory of operationProduct Description

• As an option, the diagnostic unit can also calculate the maximum weighted averageor maximum acceleration value. In this case, evaluation and monitoring is performedusing absolute limit values without a reference value.

• Indication of early warning or main alarm: The diagnosis object or the level with thehighest degree of damage is indicated via the switching outputs.

• The damage progress of the diagnosis object is also indicated by the LED series onthe DUV10A diagnostic unit.

• The DUV10A diagnostic unit can be used with both constant and variable speeds. Toensure correct diagnosis when using variable speeds, the current speed has to besupplied via a 0 ... 20 mA current loop or a pulse input.

• If the roller bearing monitoring function is used with variable speeds, you mustensure that the operating speed related to the set values remains constant for inter-mittent periods.

• The maximum operating range is from 12 min–1 to 3500 min–1 shaft speed.

• The sensor is screwed onto the unit near the rolling element bearing radial to therotational axis (see section 5 "Installation and Startup"). If the sensor is not installeddirectly next to the bearing seat, you must perform an impulse test to check whetherthe installation location is suitable for the monitoring mode "Rolling element bearingmonitoring."

The DUV10A diagnostic unit uses different object limit values for early warning (yellow)and main alarm (red) for all defined spectral diagnosis objects. The limit values of thediagnosis objects are always based on the set teach-in value and describe a signal fan-out. "Green" always corresponds to 100 %.

To compensate differences caused by the trigger level for different speeds during vari-able-speed operation, the diagnostic value is weighted according to the "Weighted sig-nal" curve. Individual weighted curves are defined for each diagnosis object.

The DUV10A diagnostic unit uses broadband limit values to monitor the vibration levelin the time domain. In contrast to the diagnosis objects, these are absolute accelerationvalues (unit 'mg'). To compensate differences caused by the trigger level for differentspeeds during variable-speed operation, the level is weighted according to the"Weighted signal" curve.

5.4.4 Conducting an impulse test

The installation position can be checked using the impulse tester (order number14066335). For the test, a defined force is provided as close to the installation positionof each rolling element bearing as possible. The sensor measures the correspondingpulse response. The determined transfer factor is given in acceleration per force (mg/N).This value describes the quality of the signal strength. The value of the transfer factormust be greater than 5 mg/N. Reliable monitoring cannot be guaranteed if the value islower.

Procedure • Click the [Conduct impulse test] button.

• Choose the object from the table.

• Click on [Impulse test].

• Start the measurement. The basic level is measured first (baseline measurement).

• Then, execute at least one impulse using the impulse tester per measurement asclose to the rolling element bearing as possible. The software indicates the suitabilityof the installation position in a graphic and as a text.

Note The impulse test can usually be carried out during operation.

If the message "The difference between the noise level and impulse test is too small" isdisplayed, repeat the measurement when the machine is at a standstill.

If the message "Mounting location not suitable" is displayed, change the installationposition and repeat the impulse test.

11305AEN

5.4.5 Writing parameters to the sensor

• Click the button [Write parameters to sensor] to transfer the parameters to the sensorvia the RS-232 interface.

11295AEN

Only complete parameter can be transferred.

A complete parameter set must at least include the speed, a frequency factor, for rollingelement bearings the signal transfer factor and the teach-in value.

23

24


The following parameters are transferred to the sensor:

• Speed, constant or variable of at least 12 min–1 up to a maximum of 3500 min–1

• The diagnosis objects and their frequency factors:

• The analysis methods (HFFT and / or FFT)

• The number of averages and hysteresis

Calculation: Averages × hysteresis × 1.6 seconds = maximum diagnostic time

• The threshold values for red and yellow LEDs

• The frequency window; that is, the frequency range of a damage frequency (typicalvalue: +2 ... 7 % of the damage frequency)

• The threshold values for the level monitor

• The signal transfer constant per object

• The basic values of the teach-in run

The speed must be constant for the maximum diagnostic time at least once a day.

II



5.4.6 Teach-In

The teach-in is an automatic self-learning process performed by the sensor under typi-cal operation conditions triggered by pressing the Teach-in button on the unit or usingthe software.

The teach-in speed must lie within the range previously defined for the operating speedand should, ideally, be close to the upper operating speed.

The teach-in function (Menu [Sensor] / [Teach-In]) is used to measure the reference val-ues of the machine and store them in the sensor. Diagnostic analyses are based on theteach-in value. Therefore, you must ensure that the teach-in process is performed cor-rectly under typical operating conditions.

To ensure that the preset limit values can be used for the monitoring type 'rolling elementbearings,' you must make sure that the bearing to be monitored is not already damaged.

If the sensor is operated with different machine speeds, the teach-in run is performed ata typical speed with homogeneous operating conditions, preferably in a mid speedrange. The number of averages set is also in effect in the teach-in run.

The reference data is then recorded (FFT envelope and FFT spectrum). The file shouldbe archived. The data can be used as a reference for diagnostics performed at a laterdate.

25

26


Teach-in process After you have connected the DUV10A diagnostic unit all the LEDs light up (delivery sta-tus).

Teach-in using the DUV10A

• Press the <TEACH> button for 5 seconds. The configured DUV10A diagnostic unitadjusts itself to the operating conditions automatically. The yellow LEDs 2, 3 and 4flash.

7.1.1 Testing switching outputs

The function of the switching outputs 1 and 2 can be tested by setting them manually.To do so, choose [Sensor] / [Test switching output 1] or [Test switching output 2].

7.1.2 Teach values

The teach values are set in the sensor for each object and can be transferred andchanged manually using the function [Sensor] / [Teach values].

If you set the teach values manually, you do not have to perform the teach-in processlater. The DUV10A diagnostic unit is ready for operation immediately.

The process of setting teach values manually can be used to reuse a known referencevalue for, for example, machines of the same type.

An absolute limit value can also be obtained by multiplying the teach value by the triggerlevel.

Example:

Nominal trigger level for early warning diagnosis object 1: 800 mg

Nominal trigger level for main alarm diagnosis object 1: 1,600 mg

Set reference value: 80 mg

Results in a limit value setting for:

Early warning: 10 (corresponds to 800 mg = 80 mg x 10)

Main alarm: 20 (corresponds to 1,600 mg = 80 mg x 20)

7.3 Application

7.3.1 Parameters

Parameter sets can be created for different types of sensors. The possible input valuesvary according to the sensor type and are, therefore, taken into account in the inputfields.

7.3.2 Speed characteristics

Operating speed data is important for defining speed-related damage frequencies. TheDUV10A diagnostic unit can be used with both constant and variable speeds. To ensurecorrect diagnosis when using variable speeds, the current speed must be supplied viaa 0 ... 20 mA current loop or a pulse input.

If the nominal speed is used as information for asynchronous motors, it is important toenter the rated speed under rated load. Deviations caused by slip can be compensatedby the frequency window. If the slip exceeds 5 %, the actual speed should be takendirectly from the shaft, e.g. using a proximity switch.

Entry:

• Constant operating speed

• Variable operating speed

7.3.3 Speed input

With variable-speed applications, the DUV10A diagnostic unit must be provided with theoperating speed. A 0 ... 20 mA current loop or a pulse signal (for example, from aproximity switch) can be used to provide information on the speed. The maximumadjustment of the current loop is 20 mA. The pulse signal must not exceed a maximumswitching frequency of 10 kHz.

7.3.4 Speed calibration

The sensor has to be provided with the operating speed to monitor applications with vari-able speed. If the speed is supplied via a 0 ... 20 mA current loop, the speed input signalis calibrated using user-defined lower and upper speeds.

7.3.5 Operating range

The sensor must receive information on the operating speed range to monitor applica-tions with variable speed. This is done by specifying the lower and upper operatingspeed.

7.3.6 Pulses per revolution

Enter the number of pulses per revolution. A value between 1 and 32 pulses per revo-lution can be entered. The maximum pulse frequency that the DUV10A diagnostic unitcan process is 10 kHz. The minimum pulse band is 3 µs.

7.3.7 Constant speed

Number of revolutions per minute. You can only define one machine speed. If the diag-nosis objects (e.g. rolling element bearing) are based on different speeds (gear unit),you must also define the transmission ratio for each diagnosis object.

For machines using mains operation, the operating speed is assumed to be constant. Ifthe nominal speed is used for asynchronous motors, it is important to enter the ratedspeed under rated load. As with asynchronous machines, deviations caused by slip canbe compensated by the frequency window. If the actual operating speed deviates morethan 5 %, it is a good idea to detect the speed.

7.3.8 Teach-In speed

If the machine to be monitored is operated with variable speeds, you must define whichspeed is to be used for the teach-in run, in order to take the weighting of the referencevalue into account. The teach-in speed must be within the range previously defined forthe operating speed and should ideally be close to the upper operating speed.

7.3.9 Averages for diagnosis objects

Number of individual measurements required to calculate a spectral diagnostic analysis.A measurement takes 8 seconds, corresponds to the frequency resolution of 0.125 Hzin the spectrum, as long as all the specified frequencies are in one frequency range(0 ... 50; 50 ... 150; 150 ... 250 etc.). Ensure constant-speed operation for the resultingtotal measurement time.

Possible values: 1 (=none); 2; 4; 8; 16; 32

Recommended setting: 2

Averages can be set for the level monitor regardless of these settings.

7.3.10 Frequency window

The frequency window specifies the relative search width in the frequency spectrum foreach damage frequency. The frequency window is positioned above and below themonitored frequency. The frequency window is used to compensate for inaccuracies inthe description of the frequency location.

The input values are relative in percent.

The frequency window setting applies to all set objects, as the maximum search rangeof the individual diagnosis objects comes into effect.

Example:

Frequency window = 5 %; damage frequency = 311.5 Hz corresponds to spectral line249.

Search range = Spectral lines 237 to 286 correspond to 296.25 Hz to 357.5 Hz

Minimum value range 0.1 %

Maximum value range 20 %

7 iagnosis objectsnit Functions

7.4 Diagnosis objects

7.4.1 Response delay of the diagnosis object

To avoid false alarms, the sensor is set as standard to a response delay (hysteresis) of5. This means that an increase in the diagnostic value is only displayed after a sustain-ability check confirms 5 subsequent increases. In this way, the sustainability of the dis-played diagnostic analysis is guaranteed.

The response delay can be set from 1 (no delay) to 10. The total response time thenresults from the number of averages multiplied by the defined response delay.

The response delay is triggered by a deviations of more than ± 1 in the diagnosis level,which corresponds to ± 100 %. The function applies to both increasing and decreasingvalues. The set response delay has the same effect on all defined diagnosis objects. Aresponse delay can be set for the level monitor regardless of this setting.

7.4.3 Level monitor

In addition to the frequency selective (i.e. narrow-band) rolling element bearings and/ordiagnosis object measurement, the level monitor enables vibration condition monitoringin the time domain. This so called broadband measurement provides general informa-tion on the entire system by evaluating the raw acceleration signal with regards to max-imum acceleration or mean acceleration.

7.4.4 Monitoring mode

The monitoring mode determines whether the level monitor should monitor the maxi-mum peak (peak monitoring) or the weighted average (vibration monitoring) of theacceleration signal. In contrast to the diagnosis objects, the subsequent monitoringfunction uses absolute values.

Two alarm levels and a speed-dependent signal weighting can be set.

The response delay and number of averages are set depending on the settings of thediagnosis objects.

Vibration monitoring

7.4.5 Constant switch points

The DUV10A diagnostic unit use different limit values to monitor the vibration level in thetime domain. In contrast to the diagnosis objects, the acceleration values are absolute(unit mg).

For variable speed monitoring, the vibration level to be monitored is weighted accordingto the "Weighted signal" curve to compensate for differences caused by the trigger level.

You can define two trigger levels (red and yellow), which are also used to switch the out-puts.

Alarm indication with yellow LED:

First yellow LED lights up and switching output 1 is activated

Alarm indication with red LED:

First yellow LED lights up and 3rd red LED (L) lights up and switching output 2 is acti-vated

Minimum: 200 mg

Maximum: 25,000 mg

Units:

1 mg = 0.001 g

1 g = 9.81 m/s² (gravitational acceleration)

7.4.6 Variable switch points

Variable limit values can be set via the operating speed range for variable speed oper-ation. The curve for the early warning alarm is dragged using the left mouse button andthe distance between yellow and red is specified as a percentage value. Only values thatresult in trigger levels < 25,000 mg are accepted. The exact values are displayed for thedefined teach-in speed.

7.4.7 Average level

The average level is the number of individual measurements required to calculate adiagnosis value.

The averaging of the vibration level (time domain) is set independent of the average fordetermining the diagnostic values (frequency range).

The measuring interval is 8 seconds for calculating the weighted average and determin-ing the maximum peak.

7.4.8 Response delay level

A response delay can be set separately for the level monitor independent of the settingsfor the spectral diagnosis objects. To avoid false alarms, the sensor is set as standardto a response delay (hysteresis) of 5. This means that the level value is only displayedafter a sustainability check confirms 5 subsequent increases. This ensures the rele-vance of the displayed values.

The response delay can be set from 1 (no delay) to 10. The total response time thenresults from the number of averages multiplied by the defined response delay.

7.4.9 Diagnosis objects

The machine diagnosis carried out by the DUV10A diagnostic unit is automatically built-up by defining a machine model via so-called diagnosis objects. The software canmonitor up to 5 different diagnosis objects at the same time. A diagnosis object is agroup of symptomatic damage frequencies that are defined as so called frequencyfactors. Multiplying the speed frequency by the frequency factor results in the actualdamage frequency. Therefore, applications operated at constant speed have a constantdamage frequency.

The diagnosis object is assigned an analysis method depending on the damage type.For example, tooth meshing frequencies and unbalances are monitored with the FFTmethod and rolling element bearing damage with the H-FFT method.

7.4.10 Analysis methods

The signal analysis is used to generate informative properties from the raw accelerationdata. The software for the DUV10A diagnostic unit uses methods of fast frequency anal-ysis (Fast Fourier Transformation = FFT). The analysis method differentiates betweenthe calculation of the linear spectrum from the raw acceleration data (FFT) and from theenvelope curve of the acceleration data (H-FFT). The selected analysis method can beassigned to a specific diagnosis object. In this way, for example, unbalance and rollingelement bearing damage can be monitored in one sensor.

If you select the diagnostic type "Rolling element bearing" or "Unbalance", default valuesare set automatically for diagnosing rolling element bearings or detecting unbalance.This option simplifies the parameter setting process.

If you select "Other", it is possible to set parameters for any machine damage if it char-acterized by assigned symptomatic frequencies / factors.

• Inner ring

• Outer ring

• Rolling element

You can use the rolling element bearing database or enter your own bearing data.

7.4.14 Other

The damage type "Other" can be used to set any machine damage by specifying thedamage frequencies (factors) for each diagnosis object.

7.4.15 Transmission ratio

Gear transmission measuring speed / object speed

The transmission ratio specifies the differences in speed between the motor shaft andthe shaft to which the rolling element bearing object) to be monitored is connected, aslong as the specified speed relates to the motor shaft and the shafts are connected viaa gear unit.

(Meas. / obj.) < 1 => increase in speed relating to the motor

(Meas. / obj.) > 1 => decrease in speed relating to the motor

7.4.16 Designation

Enter an alphanumeric designation for the diagnosis object to be monitored.

The frequency factor (subobject) divided by the gear transmission ratio (quotient ofmeas. / obj.) must not exceed the value 50.

51

52


7.4.17 Damage frequencies

Enter the damage frequencies (subobjects) that are to be assigned to a particular typeof machine damage (object).

A maximum of 20 individual frequencies can be defined using the DUV10A diagnosticunit. These frequencies can be assigned to a maximum of 5 diagnosis objects.

The characteristic data for the object is calculated using the total of the individual ampli-tudes at a given frequency.

The frequencies are described using the so called fundamental frequency analysis.Hereby, the required frequency from a fundamental frequency is multiplied by the cur-rent rotational frequency.

The fundamental frequency is a multiplication of the rotational frequency. The damagefrequency is calculated as follows:

Damage frequency = fundamental frequency x rotational frequency

Example: Fundamental frequency = 6.23, rotational frequency = 50 Hz => damagefrequency = 311.5 Hz

The fundamental frequency always relates to the corresponding frequency of thedefined error object. If different speeds are used between the objects, the correspondinggear reduction has to be taken into account.

7.4.18 Frequency window

The frequency window specifies the relative search range in the frequency spectrum foreach damage frequency. The frequency window is positioned above and below themonitored frequency. The frequency window is used to compensate for inaccuracies inthe description of the frequency location (tolerance corridor).

The input values are relative in percent.

The frequency window setting applies to all set objects, as the maximum search rangeof the individual diagnosis objects comes into effect.

Example:

Frequency window = 5 %; damage frequency = 311.5 Hz corresponds to spectral line249.

Search range = Spectral lines 237 to 261 correspond to 296.25 Hz to 326.25 Hz

Minimum value range 0.1 %

Maximum value range 20 %

DU



7.4.19 Limit values - diagnosis objects

The software for the diagnostic unit uses different limit values for early warning (yellow)and main alarm (red) for all defined spectral diagnosis objects. The limit values of thediagnosis objects are always based on the set teach-in value and describe a signal fan-out. "Green" always corresponds to 100 %.

Value range for early warning: 2; 3; 4;...; 20 (in whole numbers) corresponds to: 200 %;300 %; etc. Value range for the main alarm: 6; 7; 8;.....; 99 (in whole numbers that al-ways have to be 4 more than the set yellow value to achieve whole intermediate valuesfor the yellow LEDs).

To compensate differences caused by the trigger level for different speeds during vari-able-speed operation, the diagnostic value is weighted according to the "Weighted sig-nal" curve. Individual weighted curves are defined for each diagnosis object.

If the diagnosis type "Rolling element bearing" is selected, the limit values and weightedcurves are set automatically.

7.4.20 Transmission characteristics

The transmission factor measures the mechanical transmission of peak pulsesequences relating to rolling element bearing damage.

The transmission factor can be tested using a mechanical impulse test when the sensoris connected. The sensor must be mounted correctly in the designated location and theimpulse must be provided as close to the bearing to be monitored as possible.

The transmission factor can also be entered manually offline. The unit is mg/N, i.e.acceleration per force.

If the sensor is mounted directly on the bearing seat, you do not have to perform theimpulse test. The manual input value is typically 10 mg/N.

7.4.21 Signal weighting

For variable speed monitoring, it is possible to correct the variables independent of thespeed. The values displayed indicate how the variables of constant damage changewith speed. The change is taken into account during the evaluation and calculation inthe sensor.

The teach value and the measured value are weighted using the signal weighting table.The teach value is weighted using the specified teach-in speed, and the measured valueusing the measured speed. You must keep to the teach-in speed during the teach-in run.

You can either use predefined curves or create and load your own. If you use the diag-nosis type "Rolling element bearing damage" when setting parameters, preconfiguredsettings are loaded. These can be changed as required.

Also indicated is the extent to which the teach-in value is adjusted in the signal-weighteddiagram shown in the "Subobjects" and "Objects" modes. (D = (c / b) x 100 %)

The following formula applies:

11302AEN

Damage level (or limit value) =

Measured value in mg / signal weighting at measured speed (a)

Teach-in value in mg / signal weighting at teach-in speed (b)

DU



Determine the damage level (300 mg at 5,000 rpm, teach-in 65 mg), taking the signalweighting into account:

The required teach value can also be determined in order to exceed the yellow limitvalue (4) for given values (300 mg at 5,000 rpm)

Solved according to X (teach-in value)

The path for the user-defined database can be entered again in order to reintegratepreviously stored bearing databases or to include new bearing databases.

7.5.4 Impulse test

The impulse test measures the signal transmission from the object to be measured tothe installation location of the sensor. This test determines the suitability of the installa-tion location ([Signal path] / [Mounting test]). Furthermore, limit value parameters can beset automatically ([Signal path] / [Diagnosis object]).

The impulse test is triggered using the start button. Before a pulse is emitted, the back-ground noise of the machines is measured.

Next, a pulse is input at the relevant bearing seat using the impulse tester (part number14066335), and three pulse responses are measured at the designated installationlocation.

The results of the impulse test are only valid if there is sufficient distance between thebackground noises and the test results, and the value deviations do not exceed 40 %.

If the background noises are too strong, we recommend repeating the measurementswhen the machine is not in operation.

A minimum result of 5 mg/N is required to reliably monitor rolling element bearings.

7.6 Monitoring

7.6.1 Spectrum monitoring

Considers the linear spectra, the raw time signal and the envelope-modulated timesignal. The amplitudes are given in „mg-peak“. The total frequency range is displayed in7 different areas.

Furthermore, maximum and minimum acceleration, as well as the weighted average ofthe acceleration per time interval are displayed. A spectrum is calculated every 8seconds, which corresponds to a spectral resolution of 0.125 Hz. Windowing takesplace via a Hanning window.

Switching the display from H-FFT to FFT. The cursors refer to the damage frequenciesconfigured in the sensor. If you want to alter these values, the settings in the sensormust be changed. In the program settings you can choose whether the frequency rangefor the corresponding damage frequency should be displayed.

Use the right mouse button to choose from acceleration (mg), (mm/s) velocity or vibra-tion displacement (µm). In the same way, amplitude values can be displayed as peak(basic setting, calculation basis in the sensor) or RMS. To zoom into the diagram, drawa rectangle by keeping the left mouse button pressed and moving the mouse from topleft to bottom right. To zoom out, use the context menu (right mouse button).

The averages (1, 2, 4, 8, 16, 32) can also be simulated using the context menu.

Furthermore, maximum and minimum acceleration, as well as the weighted average ofthe acceleration per time interval are displayed.

7.6.2 Subobjects

In the subobject mode, the damage-relevant frequency groups are displayed with theamplitudes and found frequencies per object. The spectral evaluation can be performedusing either the raw signal or the modulated envelope time signal. The settings in thesensor are valid. If you want to change the analysis method, you must adjust the sensorparameters accordingly. New values are calculated every 8 seconds.

The diagram represents a frequency factor analysis. Furthermore, maximum and mini-mum acceleration, as well as the weighted average of the acceleration per time intervalare displayed.

You can use the right mouse button to choose from acceleration (mg), velocity (mm/s)or vibration displacement (µm). It is also possible to include or exclude the signal weight-ing of the subobjects.

The averages (1, 2, 4, 8, 16, 32) can also be simulated using the context menu.

In the spectral mode, the function to monitor diagnosis objects is deactivated, whichmeans switching outputs cannot be switched. Do not interrupt the cable connectionbetween the sensor and PC in spectral mode, as otherwise the sensor would remain inthe spectral mode and monitoring would not be possible.

7.6.3 Object mode

The weighted and average characteristic values are displayed for each object in theobject mode. The reference values from the teach-in are shown in the form of "blue bars"as long as a teach-in run has been performed beforehand.

The evaluation can be performed using either the raw signal or the modulated envelopetime signal. The settings in the sensor are valid. If you want to change the analysismethod, you must adjust the sensor parameters accordingly. As soon as new valueshave been calculated (according to the number of set averages), a new value is dis-played (see the section "Averages" page 43).

The object values can be displayed with or without weighting (make the selection usingthe right mouse button).

7.6.4 Diagnosis value

The weighted and average characteristic values are displayed for each object in thecondition mode or diagnosis value mode. The teach-in values are the reference values.

The evaluation can be performed using either the raw signal or the modulated envelopetime signal. The settings in the sensor are valid. If you want to change the analysismethod, you must adjust the sensor parameters accordingly. As soon as new valueshave been calculated (according to the number of set averages), a new value isdisplayed (see the section "Averages" page 43).

The limit values shown correspond with the set limit values in the sensor and correlatewith the LED display on the sensor.

If different averages have been set for the level monitor and diagnosis objects, the datafrom the level and diagnosis objects according to the number of averages, which are setfor the diagnosis objects, are displayed anew. The set parameters are valid formonitoring.

7.6.5 Recording data

According to the diagnosis depth (spectrum-subobjects-objects-diagnosis value), thecorresponding data can be stored continually (data streaming) and then displayedagain. This means that the DUV10A diagnostic unit can also be used as a measuringdevice.

To record or play a measurement, first open the file. The file has to be created beforeyou can record any data. The data can be recorded or visualized using the functionsdata recording or play.

7.7 Universal assignment

If no data is available for the bearings when you set the parameters for the DUV10Adiagnostic unit, in addition to the level / peak monitor, you can also configure a universalassignment, which monitors a specified frequency field using the broadband frequency.

The 20 individual frequencies of the subobjects are assigned center frequencies of aselected logarithmic frequency series and a frequency range of 10 %. The frequencyseries can be structured as follows:

The example is recommended for a velocity of 25 Hz (= 1500 upm). Monitoring will takeplace in the frequency field between 4.5 Hz and 250 Hz. Selecting a frequency range of10 % corresponds to setting a classification with approximately 4 bands per octave.

The following basic settings are required:

7HistoryUnit Functions

Once you have entered the frequency factor and a short designation, create the subob-ject by selecting [Add]. Once you have entered 5 subobjects, you must create anotherobject. The DUV10A diagnostic unit now indicates when the vibration amplitudes in oneof the created frequency bands increases by the set limit values.

7.8 History

To activate and configure the history memory, choose [Sensor] / [Sensor settings]. Todo so, select the [Activate history] check box and enter a value between 1 second and12 hours in the [Interval] field. Click [Accept] to start the history memory.

After a preset period has elapsed, the sensor continues to store the highest object valuemeasured per diagnosis object, together with the corresponding speed (with variable-speed operation), in internal memory modules. The list of the history data can be readout of the sensor using the function [History] / [Read history from sensor] or by clickingthe icon .

The display can be extended to show more values. To do so, select the correspondingcheck box in the lower section of the screen. The corresponding speeds taken at differ-ent points can also be shown (dotted line, right scaling axis).

The history data also includes the read-out time. The data can be stored as a CSV fileor XML file by selecting the icon or the following menu path: [History] / [Save/Histo-ry]. The history data can also be opened again from the file using the icon or via thefollowing menu path: [History] / [Open.../History].

Quick Startup

HandbuchQuick StartupStep Illustration Procedure Note

1 Define application

• What is to be monitored?• Define fault tree starting from the machine

structure.• Is the operating speed constant or vari-

able? If variable, how can information on the speed be supplied?

– Pulse detection– 0 ... 20 mA current loop

• Rolling element bearings can only be differentiated with different damage fre-quencies, otherwise they can be com-bined in one diagnosis object

• In case of fluctuations in the operating speed > 5% due to the load, we recom-mend that you detect the speed at the shaft.

2 Open or load a parameter file

• Set the parameter values in the DUV10A-S operating software using the wizard.

• Ensure correct bearing designation (or manufacturer).

• Ensure the correct nominal speed (observe number of pole pairs in case of multipole motors).

3 Installation

• Only install the DUV10A diagnositc unit on massive housing

• Mount vertical to the machine surface

• Transmission of mechanical vibrations has to be guaranteed,

• The installation location has to be suit-able for screw fixtures

• The tightening torque for the screw fix-ture is 7 Nm.

4

1: Supply +2: Switching output 2, 100 mA3: Supply –4: Switching output 1, 100 mA5: Speed (0 ... 20 mA) or impulse input

Electrical connection

• Connect the voltage supply and switching outputs and supply the speed, if required.

• The electrical connection may only be made by a specialist

• Disconnect the system before connect-ing the unit.

• The outputs are short-circtui proof.

5 Conduct impulse test

Check signal path with input test• The result of the impulse test must be

>5 mg/N.
