****** Page 7 ****** Measurement Sensor Mounting Screw the magnetic base onto the sensor. Do not forget to remove the plastic cover and the metal washer (it closes the magnetic field to prolong the lifetime of the magnet) before measuring. Place the plastic cover and the metal washer back on the magnet after measuring. Place the magnet on a measuring point verg carefully. The best wag how to do is to rest the edge of the magnet on its side and then slowly attach the sensor to the measuring point. If you bring the magnet near to the machine with its whole area hitting the machine all of a sudden then the strong impact can irreversibly destroy the sensor. If you use a measuring tip instead of a magnet, the measured values are not going to be stable. This is not surprising because the measured values depend considerably on the pressure of the tip at the measurement point. A magnet which attaches a sensor generates a constant pressure so the values are stable. Attention!!! Use the measuring tip only in hard to reach places where it is not possible to place the magnetic base.

****** Page 14 ****** ADASH 4900 – VIBRIO M The Stroboscope The stroboscope or stroboscopic lamp, commonly called a strobe, is a device which produces regular flashes of light on selected frequency. When we have to study or to visually inspect machinery, which has cyclically moving parts, then the stroboscope enables the user to freeze the movement (usually rotation). Imagine a rotating disc with one hole. When the flashes of light are synchronized with the disc rotation speed, then there is just one flash made during one rotation. It means that the disc is lit up when the hole is always in the same position. It is the principle of the illusion of frozen movement.

****** Page 29 ****** ADASH 4900 – VIBRIO M Adash Standards Over the ISO 10816 The factory setting of unit uses the ISO 10816 limit values for machine condition. But this standard does not use the speed for limit definition. All machines with speed in range 120 -15000 RPM use the same limit values. We are not satisfied with such approach too much. For example if the heavy spot exists on the rotor, then the mass has low effect on 120 RPM but destructing effect on 15000 RPM. Additionally this standard define only limits for velocity, not for acceleration. That is why we created the Adash standards for both vel+acc. Adash limits are not rewritten from any existing standard. It is a result of more than 20 gears of the Adash engineering team’s experience. It is difficult to invent a critical value definition which would be simple and reliable. In the figures below you can see how to derive Adash limit values. All limit values are related to the speed value. Low speed machines should generate lower vibration than higher speed machines. There are three levels of machine condition defined: GOOD – GREEN COLOUR ALERT – YELLOW COLOUR Machines that lay in this range are not acceptable for a long period of operation, theu can be operated until time when theg can be repaired. DANGER – RED COLOUR Vibration values in this range are considered as very dangerous and machines should not be operated. continue 29 adash.com

This function may not always be SUCCeSSfUl, because it may not be possible to detect the revolutions from everg spectrum (for example in machines with gears). continue 39
****** Page 40 ****** ADASH 4900 – VIBRIO M Appendix C – How to Evaluate the Failure If the speed is available, then and # vibration values are coloured corresponding to vibration limits. The speed value is required only for Adash limits. The ISO 10816 works without speed. Machine conditions are divided into 3 levels, which have the same colours as traffic lights: GOOD – GREEN COLOUR The machine is in good condition, no defect is found. The operation is without restrictions. ALERT – YELLOW COLOUR The beginning of a defect has been found on the machine. It is possible to operate the machine. However, more attention must be paid to the machine and the repair must be planned. ANGER-REDCO OUR There is a serious defect found on the machine. Machine should not be in operation. 40 Overall PEAKValues 12:4 1 mm/s-[TRUE o-P] 4.92 g – [TRUE o-P] The rules for evaluating the measured values are similar to the previous screen, with one difference; the peak (PEAK) vibration values are displayed. It is the highest measured value in certain time, which is important for transient shock events evaluation, especially in cases of developing bearing defects, such as: microscopic peeling ofa hardened surface lager at the point of contact between a rolling element and a bearing ring (regular shocks), adash.com — contamination of the bearing space with metal particles (irregular shocks), — cracks. Shocks which cause these defects are also included jn the RMS vibration values. However, the peak value of such a shock is hidden in a value which contains all other information about the vibrations, i.e. noise from possible abrasion, incorrect lubrication and overloading. To simplify, the RMS is an average value of all vibration values achieved in a certain time. If a large peak value (one shock) appears in this time period, it will be lost in the final recalculation of all the values. Practically this means that during the increase of the bearing defect which causes the shock, the PEAK value of this shock will visibly increase, while the RMS value will only increase slowly. The initial defect time of the bearing can be discovered sooner but the PEAK value is not as stable as the RMS value. For bearing condition measurement the RMS measurement is sufficient.

When the graph shows a number of lines (typically 3 or 4) with the same space between them (harmonics) and the first line is on the speed frequency mechanical looseness or misalignment are probably the machine problem. When the 2x speed line is verg high, then the misalignment is more probable. In our example GME is 1625 Hz. The 1.6 kHz is in the middle band. When the level of middle band is higher the other bands, then verg probably the condition of 65 teeth gear is the failure. When only the third band level is high and the small bearing is used, then there is probably bearing failure. continue 41

****** Page 44 ****** Calibration Each unit is calibrated in AC voltage using a pure sine signal generator. All graphs and values below are measured in this wag. The accelerometer is not used for the calibration, because the frequency response oscillates +/-3dB (it is +/-30% or +/-40%) in the 1 -10000 Hz range. This uneven property does not allow using it for calibration. The voltage accuracy of the instrument is high (+/-2.5% or +/- 5%) compared with the accelerometer.

See the Power OFF screen, which contains this information. Keep the middle button O pushed down and read the information. er,V440MdtH .N. 1325415 ilt. 0 5kHz/ ICIHz en.: 100.0 mV/g POWER OFF. ADASH 4900 – VIBRIO M Description of numbers on the switch off screen: 1. Firmware version 2. Serial number 3. HP filter frequency for bearings (0.5 kHz), HP filter frequency for ISO (10 Hz) 4. Sensor sensitivity (100 mV/g) The sensitivity of the sensor is USUallg in the 95 105 mV/g range. Basic Test with the A4801 Sensor Simulator If you have the A4801 unit, gou can regularly test the unit on two frequencies – 80 Hz and 8 kHz. On the initial screen RMS values of velocity and acceleration are displayed. The velocity value Should be 10 mm/s and the acceleration should be 0.5 g. The signal from the A4801 is adjusted for exactly 100 mV/g sensitivity. When the sensitivity of the unit is e.g. 95 mV/g, then the higher values (10.5 mm/s and 0.53 g) will be displayed. Expected values from the A4801 should be multiplied by a 100/95 coefficient. Basic Test with Sensor and Shaker The procedure should be the same as with the A4801. Set 10 mm/s at 80 Hz on the shaker and check the RMS velocity value on the initial screen. Then set 0.5 g at 1.2 kHz or higher and check the RMS acceleration. Below 1.2 kHz the HP filtering is applied and the result would be distorted. continue 45 adash.com
****** Page 46 ****** ADASH 4900 – VIBRIO M Appendix E – Response Specification for Calibration Advanced Tests of Velocity Measurement Use the shaker and sensor. You can measure the frequency response and the amplitude response. Use a 10 mm/s amplitude for the frequency response test. Change the frequency from 6 to 1200 Hz and draw the curve. This is the exact response with the sensor. Set 80 Hz for amplitude response. Change the amplitude from 0.1 to 100 mm/s and read the values. 46 Advanced Tests of Acceleration Measurement Use the shaker and sensor if gou are able to shake high frequencies. If gour shaker system does not allow it, use the signal generator and switch the ICP@ off. Contact gour re-seller for information on how to switch the ICP@ off. That information is not written in this manual. You can test the frequency response and the amplitude response. Use a 1 g amplitude for the frequency response test. Change the frequency from 500 to 12000 Hz and draw the curve. Set 1.2 kHz or higher for the amplitude response. Change the amplitude from 0.1 to 10 g and read the values. adash.com Envelope Demodulation Test The envelope value is an RMS value. Do not compare it with peak values. Switch the ICP@ off and use an 8 kHz pure sine signal with a 1 g (100 mV) amplitude. The ENV should display approx. 1.41 g. When you use the A4801 Sensor Simulator do not switch off the ICP@. Remember, that the A4801 only generates 0.5 g. That is why the ENV will display one half of 1.41 g (0.70 g).
