VP-80 drectory structure n conjuncton wth Report & EXamner software In conjuncton wth the Report & EXamner software module names and analyss software, the VIBROPORT 80 has varous specal features n the mplemented drectory structure. As the VIBROPORT 80 platform s a Wndows system, you can access the drectores of the VIBROPORT 80 drectly. Retan the exstng drectory structure. Never delete or move drectores. Do not create new drectores or folders. Any change to the orgnal drectory structure can adversely affect the functonng of the VIBROPORT 80. The drectory names are not dentcal to the relevant module names. However, unloadng the measurng data s easy, as Report & EXamner software correctly assocates the measurements from the respectve modules wth the specfc drectory locatons. To enable you to easly fnd the desred data when drectly accessng the VIBROPORT 80, we shall now explan the concept and the drectory structure n more detal. Drectory structure and measurng fle types Each module has two root drectores whch are derved from the storage meda on the VIBROPORT 80: Internal Dsk (nternal storage medum) 48

56 Storage Card (external,.e. removable storage medum / SD card) Fles n *.wav format from the tme sgnal and trackng modules are physcally present but not vsble. An addtonal *.csv fle s stored n the drectory nstead. The *.wav fle s used for unloadng to Report & EXamner software and for data analyss. The followng table provdes an overvew of the assgnment of measurng fles from the modules to the drectory structure on the VIBROPORT 80: Overalls, FFT Analyss, Balancng, Trackng and Transfer Functon modules Module Overalls FFT Analyss Drectory path and drectory name on VP-80 \Internal Dsk\Overall \Storage Card\Overall \Internal Dsk\Analyser \Storage Card\Analyser Explanaton and fle format *.csv *.csv. Ths drectory structure contans the subfolders Recorder and ConfCheck. Some data from the Tme Sgnal and Acceptance Test modules are stored here. Do not save your measurng data n the two subfolders Recorder and ConfCheck, but drectly n the FFT- Analyzer folder,.e. drectly under Internal Dsk or Storage Card. 49

Fg. 10 Structure of the operator nterface [1] Header lne [2] Work area / Masks [3] Status lnes [4] Functon keys (softkeys) Ths s an exemplary, generalzed llustraton. The man mask (start mask) of the VIBROPORT 80 has no status lne. 55

63 Header lne The header lne contans the followng nformaton: The name of the current mask s shown on the left of the nfo lne. If the VIBROPORT 80 has an SD storage card, ths s ndcated by a dskette symbol. The state of the ftted battery or the connecton to the power supply module s dsplayed on the rght. The current date and tme are dsplayed on the far rght. Work area / Masks The menus, measurng modules, measurng tasks and the masks wth content (dagrams, measurements, text) are dsplayed n ths area. Status lne The status lne provdes specal operatng nstructons for the current dsplay. Functon keys (softkeys) The softkeys show context-dependent functons for the respectve menu or open another menu. Pressng the functon key executes the dsplayed functon or opens another menu. 56

64 7.3 Man mask The man mask appears when the VIBROPORT 80 s swtched on. You can access all of your modules from here. Fg. 11 Man mask Only some of the dsplayed modules can be nstalled, dependng on the lcensed features of your VP-80. Cursor keys The desred module s selected by pressng the cursor keys (left, rght, top, bottom). Input keys (fre keys) The selected module s started by pressng one of the three nput keys (fre keys). 57

65 Help, System Setup and Informaton (INFO) You can use the softkeys HELP, SYSTEM SETUP (the general system setup) and INFO at the bottom of the screen to call up basc nformaton on the VIBROPORT Lcensng You can retrospectvely purchase and nstall modules on your VP-80. Modules whch are not yet nstalled have a gray background. In the ntal mask, go to the module that you wsh to nstall. Press one of the three fre keys. An nput wndow opens Enter the lcense number provded by B&K Vbro. Confrm the nput wth OK. The followng module descrptons refer to the complete, lcensed functonalty. 58

66 7.5 Module overvew Pctogram Descrpton of the module Overalls The Overalls Module allows you to analyze the overall condton of a machne and compare t to the lmt values accordng to DIN ISO or the manufacturer s data and emprcal values, for example. A sngle overall can provde nformaton on the overall condton of a machne, enablng a basc condton assessment to be carred out easly and effcently. In addton to the vbraton overalls, overalls for assessng the rollng-element bearng condton (BCUp, ECUp) can also be recorded and evaluated. Up to four measurng channels plus speed are avalable. Each measurng channel has two dgtal sgnal processng paths A and B. Several measurements can thus be performed n parallel. In addton, the Overalls Module supports measurement and recordng of overalls as a functon of speed f(n) or as a functon of tme f(t). 59

67 FFT-Analyzer The FFT-Analyzer Module allows you to break down an overall vbraton (mxture of vbratons) nto ts ndvdual harmonc components. Dfferent spectral lnes are determned wth ther own specfc frequency and ampltude. In relaton to the overalls BCUp and ECUp for the rollng-element bearng condton t s possble to calculate the envelope spectra BCS and SED, n whch the ampltudes at characterstc fault frequences correspond to the degree of damage of a component or bearng. In smple terms, the ampltude therefore stands for the degree of damage and the frequency for the damaged component. Faults such as mbalance, transmsson damage, poor algnment or rollng-element bearng damage can thus be dagnosed relably. Pctogram Descrpton of the module 60

68 Pctogram Descrpton of the module Balancer The majorty of vbraton problems on machnes can be traced back to rotor mbalances. The Balancer Module allows you to balance nstalled rotors (feld balancng). Ths means no dsassembly or transport of the rotor, consderaton of the nstallaton stuaton and balancng rrespectve of the sze and weght of the rotor. For better orentaton durng the executon of balancng, you can choose between a clear representaton of the balancng process n table form or ndvdual measurng masks (polar plots, numerc dsplay wth bar graph). In addton to basc 1-/2-plane feld balancng (statc/dynamc), the module offers 1-/2-plane balancng wth prognoss, 2-plane balancng wth just one vbraton sensor and free selecton of the correcton method: polar,components, fxed weght. 61

69 Pctogram Descrpton of the module Trackng Trackng s carred out durng operaton of the machne and serves to analyze the rotor frequency-nduced vbraton components and ther harmoncs wth speed varaton. The Trackng measurng module can be utlzed for both run-up and coast-down of the machne. The raw vbraton sgnal and the speed are recorded durng run-up and coast-down. Up to three measurng channels plus speed are supported. After the measurement, you can defne n a setup whch method you wsh to use to evaluate respectvely to post-process the recorded sgnals. As the raw vbraton sgnal s avalable, you can repeat the analyss as often as you lke wth dfferent setups. The results of ths so-called post-processng can be vewed usng Bode, Nyqust, FFT waterfall, spectrogram or table vew optons. Tme Sgnal The Tme Sgnal Module enables the user to record a raw sgnal and save t n a standard fle format (.wav). Ths format permts subsequent post-analyss by, for example, the Report & EXamner software or MatLabTM. Up to 4 vbraton nput channels or 3 vbraton nput channels plus a speed reference are supported. 62

70 Acceptance Test The Acceptance Test Module can be used for qualty nspectons n batch producton (fnal acceptance), for example. It compares recorded overalls wth lmt values establshed by DIN ISO 10816, for example. The module also allows you to draw on predefned or personally defned measurng tasks (format templates for the measurng procedure). Up to 64 frequency bands n the frequency range and 8 alarm levels are supported. The alarm levels are color-coded for a better overvew. Pctogram Descrpton of the module Transfer Functon The Transfer Functon Module enables you to carry out structural tests on machnes wth shafts that are not rotatng and to analyze mmovable objects such as, e.g. foundatons or frameworks. The transfer functon s determned usng an mpact hammer wth bult-n load sensor, and s gven by the rato between the nput sgnal (load ntroduced by the hammer hts) and the output sgnal (measured vbraton), whch s shown n the form of a Bode dagram. The coherence of the measurement s also dsplayed; ths s a measure of a largely lnear sgnal transmsson, free from nterference. In addton to the most well-known transfer functons such as stffness or moblty, four further nput sgnal to output sgnal ratos are also avalable to the user. The acquston of up to three vbraton measurng channels (mpulse responses) are also supported. 63

71 Pctogram Descrpton of the module System Setup In the System Setup you can defne the most mportant global system parameters of the VIBROPORT 80, such as the system of unts or the tme, for example. Sensor Setup In the Sensor Setup you can look at the settngs for the sensors predefned n the measurng modules (Brüel & Kjaer Vbro sensors). You can also select or defne sensors for the entre system here. These are then avalable to you n all setups wthn the modules wth the specfcatons whch you have defned. Ths permts the ntegraton and effcent use of sensors from other manufacturers. 64

72 7.6 Softkeys General Softkeys are called up va the respectve functon keys (F1 to F6). The softkeys are dynamc and adapt accordng to the gven mask and stuaton. Change softkeys These softkeys change automatcally when actvated wth the functon key. For example: HZ/rpm or EXPAND/REDUCE. Gray softkeys When these softkeys are actvated wth the functon key, the functon s actvated. The softkey appears gray untl t s executed agan and the functon s thus deactvated agan. For example: AVERAGE or RECORD. Dynamc softkeys If you change to another level, for example, or navgate to specfc measurng tasks, Help or New Measurement, certan softkeys are automatcally faded n or out. I.e. the functonalty of the softkeys s context-senstve. For example: SYSTEM SETUP or START. The operator nterface of the VIBROPORT 80 has four levels n whch you can navgate wth the softkeys (see followng fgure). 65

These can be started drectly or started wth recallng the setup behnd the predefned measurement. > BACK Ths softkey takes you back to the man mask of the module. 69

77 SETUP Select a predefned measurement, the last measurement or a new measurement wth the cursor keys. You can use the SETUP softkey or the fre key to call up the respectve setup for the selected mask or measurng task and to adjust the setup parameters (for example hardware used, unts, hgh-pass/low-pass, lmt frequency, etc.). The measurement can then be started wth the START softkey or the fre key. REPORT Here you can load, dsplay and manage the saved setup settngs, measurements and *.wav fles. The report s started wth the fre key or the REPORT softkey. There s no START or SETUP softkey. START If you select Last measurement or a predefned measurement wth the cursor key and actvate the START softkey, the measurement s started drectly. If you select a measurement and press the fre key or SETUP, a setup opens n whch you can edt the settngs, before startng the measurement wth START. The START softkey s not avalable for New measurement or Report. EXIT Actvatng the EXIT softkey takes you back to the man mask / module overvew. 70

78 7.6.5 Level 3 / Measurement setup and report mask Measurements that are started wth the fre key open a setup nput mask before the measurement, where the settngs for the measurement are defned. All softkeys are only avalable here, f a measurng fle or setup fle has been selected n the report mask! Measurement setup HELP Actvatng ths softkey dsplays general nformaton on the measurement setup (cursor keys, fre key, softkeys). The measurement setup parameters are also descrbed n detal here. DEFAULT Actvatng ths softkey resets the settngs of the measurement setup to the default values. EXPAND/REDUCE The EXPAND softkey fades n all settng optons for the setup. The REDUCE softkey dsplays fewer settng optons. STORE The STORE softkey saves the currently set setup n the Report mask so that t can be reused later. START The measurement s started wth ths softkey. EXIT The setup s rejected wth ths softkey. The settngs and measurements can be used agan wth the OPEN softkey. 71

79 Report mask HELP A bref descrpton of the softkeys for the Report mask s dsplayed here. UP Ths softkey goes up one level or takes you back to the prevous level. BACKUP The fle selected wth the cursor keys s saved by executng ths softkey on the SD storage card of the VIBROPORT 80.

OPEN If you select a fle (saved setup/measurement) and actvate ths softkey, the setup or measurement s opened and can be vewed and performed agan. EXIT Ths softkey returns to the mask of the current module. 72

80 7.6.6 Level 4 / Measurements mask Ths s the level n whch the actual measurements are performed. Although ths can be accessed drectly from the second level (START softkey on a blue con), t s normally only accessed from the thrd level (setup). As whch functon keys and softkeys are avalable depends on the respectve measurng module, the most mportant softkeys and ther functon are explaned brefly below by way of an example. AVERAGE Executng the AVERAGE softkey averages the current / acqured values of the measurement (average value formaton). The softkey s dsplayed wth a gray background. When the softkey s actvated agan the values are dsplayed unaveraged once more, and the AVERAGE softkey s dsplayed wthout a gray background. VIEW Actvatng ths softkey opens a mask for settng the dsplay / representaton of the measurement. Whch dsplay / representaton can be selected depends on the measurement. Some settng examples are shown below for the OVERALLS module: Numerc dsplay optons Only table [A+B] A+B+bar chart Table [A] CH 1 + CH 2 A + bar chart (CH 1) A + bar chart (CH 2) Y-axs dsplay Lnear Logarthmc 73

81 LOG / LINEAR When the LOG softkey s actvated the Y-axs s scaled logarthmcally and the LINEAR softkey s dsplayed. The LINEAR softkey scales the Y-axs lnearly. CPM / HZ Ths softkey swtches the dsplay between the unts rpm (revolutons per mnute) and HZ (vbratons per second). PAUSE/CONT. If the PAUSE softkey s actvated the current measurement s paused but not nterrupted, and the CONT. softkey s dsplayed. The actual measurement contnues runnng n the background. If the CONT. softkey s actvated, the measurement s contnued mmedately. EXIT In the masks n whch measurements are performed, the measurements are concluded wth the EXIT softkey. A securty query then appears wth the followng optons: STORE When ths softkey s actvated the measurement can be saved n the Report mask. EXIT The EXIT softkey rejects the current measurement and returns to the man mask of the current module. BACK Cancels extng of the measurement and returns to the measurement. The followng softkeys are only avalable n the Balancer module! 74

82 POLAR / BARGRAPH When the POLAR softkey s actvated balancng s dsplayed n a polar vew, and when the BARGRAPH softkey s actvated the vbraton values are shown as a bar chart. TABLE The TABLE softkey opens the Summary mask, whch dsplays the measurng values as a table. 75

83 7.7 Measurng data analyss - zoom and cursor keys You can select ndvdual measurng data values n measurements wth the cursor keys and magnfy measurng curves wth the zoom key. Ths allows you to vew measurng ranges n more detal and analyze them. The status lne also dsplays whch keys / cursor keys can be used for zoomng n, and whch other functons are avalable to you (Peak, Harm. Cursor). Zoom n X-axs The X-axs s zoomed n wth the plus/mnus key. The zoom factor s changed by pressng the key repeatedly. For example, the dsplayed spectrum of 0 to 1000 Hz s reduced to a secton of 0 to 200 Hz. Zoom n Y-axs The Y-axs s zoomed n wth the cursor keys (up, down). The scalng of the Y-axs s changed. The Up cursor key enlarges the secton, whle the Down cursor key reduces t. Lnes / ampltudes are cut off n the representaton f they are greater than the currently selected range end value. The numerc dsplay of the frequences and ampltudes s not nfluenced by the representaton. 76

84 Usng the cursor keys Durng the measurement and when t s fnshed, nformaton about ndvdual spectral lnes/ampltudes can be selected wth a cursor. The current X/Y poston of the cursor s dsplayed n the top left corner (near the header lne). Ths means that you always know where the cursor s located. Actvate the cursor functon by pressng the cursor key (rght, left) once. Select the desred poston by pressng the respectve cursor key (rght, left). The measurng values for the selected poston are dsplayed numercally. Informaton e.g. on the ndvdual spectral lnes (ampltude and frequency) s also dsplayed. Mscellaneous keys Harmonc Cursor The Harmonc Cursor s actvated wth key 4. Actvatng ths softkey agan deactvates the cursor / fades t out. Peak Fnd Cursor The Peak Fnd Cursor s actvated wth key 7. Ths cursor jumps to the max. 5 hghest peaks n a spectrum. Actvatng ths softkey agan and agan, cycles through the hghest peaks.

When deletng a sensor please note that t wll no longer be avalable for measurements, or wll have to be newly created frst of all. The sensors avalable on delvery of the devce cannot be deleted (context-senstve fadng out of the DELETE softkey). 85

93 8 Example measurement - Overalls The Overalls module allows you to analyze the overall condton of a machne and compare t to the lmt values establshed by DIN ISO or the manufacturer s data and emprcal values, for example. A sngle overall can provde nformaton on the general condton of a machne, enablng a basc condton assessment to be carred out easly and effcently. In addton to overalls for the absolute bearng vbraton and the relatve shaft vbraton, overalls for assessng the rollng-element bearng condton (BCUp, ECUp) can also be evaluated. Up to four measurng channels plus a speed reference are avalable. Each measurng channel has two dgtal sgnal processng paths A and B, allowng several measurements to be performed n parallel. The Overalls module also supports measurement of the machne shaft speed and recordng of overalls as a functon of speed or tme. 86

94 Fg. 15 Overvew of overalls [1] Last measurement [2] Predefned measurement [3] New measurement [4] Report There are several optons for performng a measurement. Last measurement Last measurement saves the setup last used for a measurement. Ths automatc savng (under the Last measurement con) s performed f you have called up a measurng mask wth any setup (level 4). You have the followng two optons wth Last measurement: You can perform the Last measurement and check the Setup beforehand by means of the fre key or the SETUP softkey, or start the Last measurement drectly (START softkey). 87

95 Predefned measurements Here you can start the measurements (measurng tasks) predefned by Brüel & Kjær Vbro GmbH. The predefned measurements reflect frequently occurrng, typcal and mportant measurng tasks n condton montorng. The settngs for the respectve measurement are already predefned and cannot be deleted by the user. However, the settngs of the predefned setups can be adapted for an ndvdual measurement. When a predefned measurement s next called up, t s reset to the default settng. Alternatvely, t s possble to save self-defned setups as a fle and load them wth the Report functon. You cannot create new (self) predefned measurements. New measurement You can defne a new setup for a measurement by selectng New measurement and pressng the fre key. When the Setup has been edted, the new measurement s started wth the START softkey or the fre key. Report You can call up the Report mask wth the REPORT softkey or the fre key (the REPORT con must be selected /hghlghted). In the Report mask you can back up (BACKUP), delete (DE- LETE) or open and execute (OPEN) the saved setups and measurements. Fg. 16 Setup of the last measurement 88

96 You wll fnd setups (dentfed by a sheet as con) and measurements (dentfed by a sheet wth a tck as con) lsted here. 8.1 Start of example measurement The Overalls module s used for the example measurement here. In prncple all module masks / overvews are very smlar and are operated accordng to the same logc. The procedures and settngs descrbed below can therefore be transferred to the other modules. Proceed as follows: Start the VIBROPORT 80 wth the On/Off key. The devce starts. The man mask appears. If you have not yet correctly connected the necessary sensors to the VIBROPORT 80, do ths now. Select the Overalls module wth the cursor keys. Press the fre key. The Overalls mask opens. 8.2 Perform new measurement You can perform a new measurement here. Before startng a setup mask wll be dsplayed, n whch you can set up the new measurement. Select New measurement wth the cursor keys. Press the fre key. Edt the Setup f necessary. Press the START softkey. The STOP and STORE softkeys allow you to save the current measurement n thereport and reuse t. Perform the new measurement. End the new measurement wth the EXIT softkey. 89

97 8.3 Perform predefned measurement Predefned measurements are specfcally desgned for frequently occurrng measurng tasks. Therefore these measurng tasks do not have to be specally created and saved. Predefned measurng tasks can be started drectly (START softkey) or confgured (fre key) or SETUP softkey before startng the measurement. The settngs of the setup can be ndvdually confgured, but wll always be reset to the respectve default settng when the setup s next used. Select the predefned measurement wth the cursor keys. Press the START softkey (drectly to measurement) or the fre key or the SETUP softkey. Edt the Setup f necessary. Press the START softkey. The STOP and STORE softkeys allow you to save the current measurement as a report and reuse t. Perform the predefned measurement. End the predefned measurement wth the EXIT softkey. 90

98 8.4 Perform last measurement and check setup If you wsh to call up and check the settngs of the Last measurement (or a predefned measurement) before you perform ths measurement, proceed as follows: Press the fre key (or the SETUP softkey). The Overalls setup mask opens. Fg. 17 Setup of the last measurement The EXPAND softkey dsplays all settng optons for the setup. The REDUCE softkey only dsplays the basc settng optons, whch are adequate for most applcatons. Check the connected sensors n the Setup of the Overalls. Edt the Setup settngs f necessary. Save them wth the STORE softkey, f you wsh to reuse the edted settngs at a later pont n tme. Start the measurement wth the START softkey or the fre key. The measurement starts. 91

99 8.5 Drectly start last measurement If you wsh to repeat the Last measurement carred out, proceed as follows: Press the START softkey. The Overalls data mask opens and the measurement starts drectly (ndcated by softkey F5 whch dsplays STOP = Measurement runnng). Fg. 18 Measurement of overalls In ths example a sngle-channel measurement, wth overall only n path A, s dsplayed n both a table and as a bar chart - the man value selected n the setup was [mm/s] rms (see prevous page). The softkeys provde dfferent functons durng the measurement. 92

100 Durng executon of the measurement you can: Call up an average determnaton to stablze the measurng values (AVERAGE). Change the representaton (VIEW). Record the data over speed f(n) or tme f(t) (RECORD), f you have prevously defned ths n the setup. Pause and contnue the measurement (PAUSE/CONT.). Start / stop the measurement (START / STOP). And ext the mask (EXIT). If you have pressed STOP, you can save the measurng data (STORE). After extng the mask you return to the Overalls mask. 8.6 Change dsplay / representaton durng measurement The Overalls module and the other modules have dfferent optons for dsplayng the measurng results. 93

101 You can select ndvdual representatons (tabular vew) or combne dfferent representatons (tabular vew + bar graph). Start the measurement wth the START softkey. Press the VIEW softkey. The followng mask opens: Fg. 19 Dsplay optons Select the desred parameter wth the cursor keys, edt t and press the fre key. Press the OK soft key. The measurement contnues runnng and s shown wth the new dsplay / representaton. 8.7 End current measurement When endng a runnng measurement a standard query dalog appears n all modules. Ths specfes dfferent procedures. Go to the measurement. Press the EXIT softkey. 94

102 STORE When you press ths softkey the current measurement s saved as a report and can be called up agan later. EXIT The measurement s rejected, not saved and you are returned to the Overalls mask. CANCEL You are taken back to the last measurement. The last measurng data can then be dsplayed. 8.8 Save measurement You have the opton of savng measurements. Ths means that you can call up measurements whch you have adapted n the module setup and n the measurement overvew at any tme. In addton to the measurng result, the setup whch s lnked to the measurement s also saved. End the measurement wth the STOP softkey. Press the STORE softkey. The followng mask opens: 95

103 Fg. 20 Report overvew Allocate a new name for the measurement, usng the alphanumerc keypad or accept the name suggested by the VP-80 (Name: Date / Tme). Press the OK softkey. The measurement s saved. 96

104 8.9 Load and execute saved measurement (open report) Ether load saved measurements, so that you can reuse ther setup for another measurng task, or drectly use one of the setups stored here for your next measurement. The REPORT mask wll assst you. Press the REPORT softkey. The followng mask opens: Fg. 21 Report overvew Select the desred measurement wth the cursor keys. Press the SELECT softkey. The measurement s opened. Press the START softkey. The loaded measurement s performed. 97
