Overview

The VIBROSTORE 100E (VST-100E) is a simple to use rugged vibration monitoring and portable analysis instrument with on-board display of vibration levels. VST-100E provide basic vibration indication functions based on machine running speed. This functionality may help to diagnose faults, indicating main parameter for unbalance, misalignment, and looseness, to be confirmed with further analysis.
The VIBROSTORE 100E is approved for use in “Potentially explosive atmospheres” in accordance with the ATEX Directive. Here, this approval also extends to cover use as Category 2 equipment for gases (ATEX).
The system is designed to take vibration measurements from assets (e.g. pumps, motors, fans and bearings) a simple route-based data collection mode. The unit displays vibration frequency plots and allows vibration severity and bearing condition to be monitored. VST-100E will collect and display all measurements in in as little as 3 seconds with one push of a button.
Combined with the powerful ReO software, the collected measurement data can be exported and used to perform even more advanced analytics and computing tasks. ReO is able to display valuable plots and graphs, to effectively detect and analyse vibration related problems of rotating machinery.
2.1 Control buttons
The VST-100E features an OLED display and 7 control buttons. Please refer to section “Operation” for a detailed description. When off, turning the VST-100E ON is achieved simply by pressing the center button. The unit will automatically turn OFF if not used for a 1 to 60 minutes selectable auto turn off time. When the main menu is displayed the device can be turned off by pressing the button for 3 seconds.
2.2 Protective boot
The VST-100E is guarded by a removable protective rubber sleeve, which can be removed, by peeling back the protective boot on the narrow bottom part of the device and pulling the boot upwards.

3.4 Taking a reading

To take a reading, press the center button to turn the unit ON.
Place the sensor on a rigid part of the machine as close as possible to the desired measurement point (e.g. bearing block) using the magnet mount.
Pressing the circle button again takes the reading.
N.B. for best results the sensor should be placed gently onto the measurement point by “rolling” the magnet onto the machine.
This is to avoid any sudden shocks that would be seen as large acceleration peaks by the sensor and could take some time (several seconds) to die away.
Taking a reading causes the overall vibration numbers screen to be displayed as shown in the example screen left.
This screen gives an overall view of the machine’s vibration condition as explained in the following section.

3.4.1 Vibration readings
WARNING! Through electro-magnetic interferences (acc. to EN 61000-4-3) influences on the measured values may arise.
Once a vibration reading has been taken, the display will show three values, as shown in the example screen (see chapter 3.4 Taking a reading). The values are color coded to show their alarm status as explained in the following sections. VST-100E can show the results as peak, peak to peak and root mean square (rms) values. The three values shown in the readings screen are:
· ISO value (velocity in mm/second or inch/s) · Bearing Noise in BDU (Bearing Damage Units) · Total g (acceleration)
These readings are explained in more detail below with some examples.

UNRESTRICTED DOCUMENT

Page 17 of 34

EN
ISO value (mm/s)
The ISO value (in mm/s or inch/s) is the large number displayed at the top of the screen. This is the RMS measurement of the calculated peak measurement of the vibration velocity in the frequency band 10Hz (600 RPM) to 1kHz (60,000 RPM) or 2Hz (120 RPM) to 1kHz (60,000 RPM) as specified by the ISO standard1. The correct frequency band is automatically selected by VST-100E based on running speed.
The ISO value background is colour coded according to the ISO 10816-1 vibration velocity level chart (see below). The colour coded background indicates the condition of the machine according to the size and type of machine selected with the Setup Wizard (see section 3.5.1).

1 ISO 10816-1:1995. Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts

Page 18 of 34

Brüel & Kjær Vibro Instructions VST-100E

EN

Bearing Condition (BDU)
Below the displayed ISO value and to the left is the value of bearing noise (high frequency vibration) in Bearing Damage Units (BDU), where 100 BDU corresponds to 1 g RMS vibration measured in the frequency band between 1kHz and 10kHz. This is an indicator of the wear state of a bearing; higher number = higher bearing wear.
It is commonly held that 1g of high frequency vibration (100 BDU) corresponds to a relatively high level of bearing noise and so can be considered indicative of a damaged bearing. In other words, it may be helpful to think of the Bearing Noise figure as being very roughly equivalent to “percentage” of bearing wear. To quickly and easy identify the wear state of the bearings the background of this tile is colour coded like the ISO value as well. By default, the bearing noise is displayed on a Red background if it is above 100 BDU, a Yellow background between 50 and 100 BDU and a Green background below 50 BDU. However, the BDU alarm levels can be changed using the Manual Setup menu (see section 3.5.2.1).
Broadband acceleration (g)
This is the acceleration vibration value in g (RMS) of a bandpass filtered signal. The filter spans from 10Hz to 10kHz. This reading is shown in units of g (Earth’s gravitational constant, where 1 g = 9.81 m/s2).
Displacement (µm or mils)
Pressing either the left or right arrow button when the reading screen is displayed will cause the VST-100E to display calculated peak or peak-to-peak displacement values (in µm or mils) on a blue background. There is no alarm level coding. The frequency band is chosen analogue to the ISO value measurement. Pressing either left or right arrow button again will revert to display of the ISO value (mm/s or inch/s).
3.4.2 Vibration Analysis (Vibration bands)
Pressing the down arrow button brings up a display. It shows the readings of vibration velocity (mm/s or inch/s), or displacement (mm or mils) if selected, broken down into each of 3 bands.
The display shows the vibration level in frequency ranges that are all based on multiples (1X, 2X and 3X) of the specified Run Speed of the machine as displayed beneath the 3 bar graphs.

UNRESTRICTED DOCUMENT

Page 19 of 34

EN

N.B. in order to perform a vibration analysis it is important that the running speed of the machine is entered correctly. This can be done with the “Setup Wizard” as described in Section 3.5.1 of this user guide.

Typical but not exclusive for the appearance of following multiples of running speed2 are:
1X = Unbalance:
The level of vibration in the frequency band based on the running speed is usually indicative of how well balanced the machine is. A large vibration at the running speed usually indicates that the machine is out of balance. However even a very well-balanced machine will typically show some vibration at the running speed, but this value should ideally be quite low (e.g. typically less than about 2 mm/sec for a medium sized machine).
2X = Misalignment:
A high level of vibration in the frequency band centred at twice the running speed is a possible indication of misalignment. Shaft misalignment can result in a double peak in the waveform. This will typically give rise to a vibration signal at double the running speed of the machine.
3X = Looseness:
High vibration in the frequency band centred at 3 times running speed is a possible indication of high mechanical looseness (e.g. loose mounting bolts, weak foundations etc.).

2 Multiples of running speed are sometimes referred to as “orders”. Page 20 of 34

Brüel & Kjær Vibro Instructions VST-100E

EN

3.4.3 Frequency spectrum
Pressing the down arrow button once more brings up a display, where the vibration levels are shown as a frequency spectrum plot in the range from 0 to 1 kHz.
The heights of the peaks indicate the RMS vibration level (in mm/s or inch/s) at each frequency point in the spectrum.
The values to the right of the screen show the frequency (in Hz or RPM) and the RMS vibration level (in mm/s or inch/s) at the position of the cursor (red dotted line). The cursor position can be moved by use of the left and right arrow buttons.
Pressing the down arrow button increases the resolution of the frequency axis from 100 Lines (i.e. 10 Hz or 600 RPM resolution) to 800 Lines (i.e. 1.25 Hz or 75 RPM resolution). Increasing the resolution effectively zooms into the frequency spectrum. To display the full spectrum at the higher resolution the display must be scrolled using the left and right arrow buttons.
3.4.4 Live Update Mode
It is possible to have the VST-100E continuously display readings that are taken at intervals of approx. 1 second.
Live Update is selected from the Configuration menu, which is entered by holding down the center button for 2 seconds.
It is possible to use live update with the basic readings screen, the VA bands screen or 100 line frequency spectrum. Pressing the center button at any time during live update will take a single measurement and stop live update mode.

3.5 Configuration menus

The configuration menu is entered by pressing and holding down the center button for 2 seconds.
Moving up and down the menu is achieved by pressing the up and down buttons which causes the menu item to be highlighted. Pressing the circle button will select the highlighted menu item. Left and right arrow buttons can be used to move backward and forward through the menus.
All changed settings will be saved immediately and do not require to be saved additionally.

3.5.1 Setup Wizard

Selecting the Setup Wizard opens a dialogue that allows the machine running speed to be entered and the ISO alarm levels to be set automatically according to the size and type of machine to be monitored.
The first Setup Wizard screen to be displayed shows the currently selected running speed in the pre-selected units (Hz or RPM).
Changing the running speed is achieved by pressing the up arrow button (to increase run speed) or down arrow button (to decrease run speed). Pressing and holding either of the buttons will quickly change the displayed value.

Page 22 of 34

Brüel & Kjær Vibro Instructions VST-100E
Pressing the center button again brings up the next screen which allows the machine type (motor or pump) to be selected.
If a motor is selected the size must also be selected (under or over 300 kW) or if a pump is selected, it must be specified whether it has an integrated or external drive unit.

EN

Selecting the machine type and size allows the ISO alarm levels to be set accordingly, as does specifying the type of mounting (rigid or flexible).
As a basic “rule of thumb”, unless a machine is bolted down to a concrete floor, its mounting should be considered as being flexible.
Many motors and pumps are mounted on a frame or structure and should be considered as flexibly mounted.

3.5.2 Manual Setup 3.5.2.1 BDU alarm settings
Selecting BDU Alarms allows the alarm levels at which the BDU readings change color to be altered by the user. Normal levels are displayed on a Green background.

The BDU threshold values are designated as ALERT (where readings turn Yellow) and DANGER (where readings turn Red). Both these threshold values can be set independently using the up and down arrow buttons.
The default BDU thresholds are 50 for ALERT and 100 for DANGER. These levels are typical for medium sized machine bearings operating at run speeds in the region of 1000 to 3000 RPM. Larger bearings or higher run speeds may need increased BDU threshold values to identify worn or bad bearings.
3.5.2.2 Run Speed
Run speed can also be set manually via the up and down arrow buttons.

Route Management

Pressing the Route Manager button (industry icon , located just below the down arrow button)
brings up the Machines menu.
Machines have user-defined names up to 16 characters long.
Scrolling the list of machines is achieved with the up and down arrow buttons.
Selecting a machine is done with the center button , which then brings up a list of measurement
points for that machine.
Measurement points also have user-defined names up to 16 characters long.
The list of measurement points can also be scrolled by using the up and down arrow buttons and each measurement point can be selected using the center button .

The various options for each measurement point (MP) are then displayed:
1. Take Measurement takes a new reading and saves it to this MP
2. Run Speed adjust the run speed of the Machine for this measurement point.
3. Save Measurement saves the previously taken reading to this MP.
4. Load Measurement loads a previous reading (e.g. for re-display)
Machines and their measurement points are downloaded from the ReO trending and route management software for PC using the supplied USB docking cradle or the Bluetooth interface.
The exact list of machines to be downloaded is determined by the user in ReO.

ReO Software

ReO is the PC based software that allows users to view trends of vibration readings taken with VST-100E, in a way that enables predictions to be made about machine condition.
ReO is very powerful and highly functional route editor and analysing software, which is described in more detail in its own instruction manual. This can be downloaded from our website. ReO allows display of vibration data in a variety of different ways including vibration frequency spectra, bearing noise and ISO trend plots, waterfall diagrams (see figure below) and can generate reports either manually or automatically (e.g. by sending out email alerts).

Optional accessories

6.1 BNC to BNC connecting cable
WARNING! Before connecting the VST-100E to any buffered output, make sure to turn off the IEPE Power (CCS) by pressing and holding the left arrow button when on the main numbers screen. IEPE can be activated again by pressing holding the left arrow button
when on the main numbers again. Otherwise this connection could damage both devices permanently.
Connecting the BNC to BNC cable to a buffered output of machine vibration detectors, the VST-100E can collect vibration data and visualize the data. This powerful function enables the user to connect the VST-100E to existing vibration monitoring devices. Watch out for installations with inverted polarity. Measurements will be false.
