  • Page 4 VMI has the aim to improve and develop our work, why surely an upgraded version of this manual will be distributed in the future. As a result of this, we might change and correct these items in later issues without further notice.

  • Page 7 The frequency appears as follows: The Frequency range of the highest peak in relation to the frequency range setting is described in the below table, the limit of the maximum frequency* of the peak is 1000 Hz. Frequency range Frequency of the highest peak 2-400 Hz 2 - 400 Hz 6 –...
  • Page 8 3 Warning messages The following message may appear in normal operation: This message may appear if the calibration data is lost from the permanent FRAM memory Calibration or if the calibration data are corrupted. In such cases, the instrument must be re-calibrated; lost! otherwise it will measure incorrectly.
  • Page 9 LED lights up until the battery is fully charged. 4.1 Changing Battery The unit has an embedded Lithium battery and after a number of years when the battery is exhausted we recommend that a VMI reseller or service centre makes the replacement. 5 How to interpret vibration levels User with no previous experience, we recommend to use the ISO 10816-3 standard.
  • Page 10 6.0 Excerpt from ISO standard Iso Standard 10816-3 classifies machines differently depending on whether they are flexible or rigid (fixed) mounted. This reflects the location of the machine's "rigid resonances" related to the machine's operating speed.
  • Page 11 7 Vibration analysis 7.1 Recommended vibration levels The following is an extraction of part of the old standard ISO 2372 class 4, large machines on flexible foundations, with some common findings added. Use this simplified list as a first indication, when approaching a newly commissioned machine or after some time in operation.
  • Page 12 The diagram above is a help to translate bearing condition values. About, for example, the measured gBC value is 2.0g. It shows that if a machine has a speed of approximately: 10000 RPM, the bearing may still be good while a machine with a speed of about 550 RPM with the same gBC value can be considered as consumed.
  • Page 13 Trends are one method to perform condition monitoring (CM). TREND VIEW™ is designed for use only with VIBER X2 Pro™ and VIBER X3™. For every plant or building, you can create a database and a rout with up to 100 measurements.
  • Page 14 9.1 Create a measurement project You start by creating a "measurement project" to store measurement values. In this manual, we show an example of how to build a "measurement project" or "database" with two grinding machines. Grinding machine 1 and Grinding machine 2. For both machines we measure : Vibration, Bearing condition (BC) The machines belong to the "Grinding department".
  • Page 15 You can also click on the symbol that shows a "white sheet of paper" to create a new project.
  • Page 16 Here is the new project. You can not measure temperature or perform balancing with VIBER X2 Pro. You can build a hierarchical tree, from a plant or department down to a single measuring point, or just set up a single machine. In this example, we select "Department"...
  • Page 17 Assign the project a name by clicking on the green "W"...
  • Page 18 Assign a project name to the project and decide where you want to save your projects. Create a "Folder" and give it a name, for example: "Trend View Project".
  • Page 19 Continue by clicking on the "Add measurement group or location" icon. Select "Department" for our example. In other cases, choose the option that suits. The top level of the project (Database) is usually a building or department, which must be added to the project.
  • Page 20 Enter a name for the department, proceed with a click on "Next".
  • Page 21 Select the type of measurement you want to do "Measuring Project" or "Balancing reports". In our ex. We choose "Measurement Projects" because we will perform trend measurements. You can not perform balancing with VIBER X2 Pro. Click "Finish".
  • Page 22 The next step is to add a machine...
  • Page 25 Mark "Grinding machine 1", drag the line to see "Slot" and "Data". The next moment is to add a measurement point (usually a bearing). In this example we want to measure two bearings in three directions for each machine.
  • Page 26 You can skip the allocation of "Slot number" and, at a later time, perform an automatic sorting of storage slots locations (Auto Assign), see pages 35 - 37.
  • Page 27 The next dialog box allows you to select alarm levels, manually or from a standard table. In the example, we choose the default.
  • Page 28 Temperature is not measured with VIBER X2 Pro™.
  • Page 30 Thus, "Grinding machine 1" is finished. To create "Grinding machine 2" you can now make a copy of grinding machine 1, and then edit it.
  • Page 34 Now we need to assign "Grinding machine 2" slot number (Storage locations).
  • Page 36 Thus, the first "project" is finish and you can now start measuring on the machines and then transfer measurement data to "Trend View".
  • Page 37 9.2 Create a "Route Plan" and edit a project We recommend that the route plan be printed out and used every time you make measurements. Make a route plan based on how often the measurement is done, such as week, month, half year etc.
  • Page 38 When selecting "Route plan", a list appears to the right in the picture, that can be printed out.

  • Page 39: Trend Measurements

    Trend measurements Perform the project (database) with the machines you want to measure within the same interval, (weekly, monthly, etc.). Mark the machines according to the printed list: Each new measurement performed on the same machine must be stored in the same "slot number"...
  • Page 40 to save a measurement, and the vibration storage table Press the SAVE key appears on the instrument display: If you want to place the measurement value in "slot number 1" confirm with the green key. If you want to move the measurement value to another slot number, use the arrow keys.
  • Page 41 (If a problem occurs, see the special installation instructions for the PC software. 2) Start the VIBER X2 Pro ™ instrument, and select "Upload" from the function menu. 3) Open "Trend View" and select "Import measurement data from instrument"...
  • Page 42 Note. The VIBER X2 Pro ™ instrument must be "on" and upload must be selected from the function menu, confirm with the green key. A rotating symbol appears on the screen. In this mode, you continue in "Trend View" by clicking "Next" in the dialog...
  • Page 43 Wait a while, and the transfer procedure will start.
  • Page 44 Since the instrument does not store times when the measurement was performed, but only time for the transfer, you have to change the date manually. If you want to save the times when the measurement was performed select: "Timestamp each measurement individualy".
  • Page 45 Here shows all vibration data from the first measurement. Note. Temperature is not measured with VIBER X2 Pro™.
  • Page 46 Data is transferred to the project,...
  • Page 47 Transmission of measurement data for "Grinding machine 1" is now complete. In order to see a graph showing the trend, at least two "2" measurements, at different times, must be performed and transferred to the project.
  • Page 48 After the second measurement for the same machine, the new measurement values are stored in the same "Slot-places" as before, in our case: 1, 2, 3 for vibration.
  • Page 49 To see a "Graph", double-click the vibration direction you want to see. The graph below shows "measurement data" after three measurements (those blue-marked in horizontal direction) and after three data transfers.
  • Page 50 9.5 General description and viewing trends After all measurements are saved, you can choose to study a graph to see any deviations of the vibration of the machine. To see the "Trend chart", select and double-click the project tree and in the direction you want to study.
  • Page 51 10.0 Technical data VIBER X2 Pro Standard 100 mV/g ± (selectable sensitivity in the instrument) Vibration transducer Accelerometer 15 % 0,1 – 9999 mV/g Vibration Max 50 g RMS Input amplitude With other sensor up to 500 g and 50 g BC.
