1 Important information
Safety precautions
Vibration measurement and balancing involves measurement on rotating
machines. Keep a safe distance to rotating parts and secure transducers and
transducer cables from rotating parts. Always follow internal, local and na-
tional security regulations! When working with weights on the rotor always
secure the start switch with a locker and also use the emergency switch for
double safety. This is especially important when the machine is remote con-
trolled.
VMI takes no responsibility for any accidents on people and machines.
VMI and our authorized dealers will take no responsibility for damages on
machines and plants as the result of the use of VIBER X3™ measurements.
VMI has the aim to improve and develop our products, why surely an up-
graded 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. Also changes in the VIBER X3™ equipment may take place that
affect the accuracy of the information.

Warning!
Incorrect setting of the emissivity factor
can lead to considerable errors of
measured temperature.
Direct the IR temperature transducer towards the surface you want to measure. Keep a distance of approximately 200-500 mm (8- 20 inches)
between the instrument and the object. Reduce the distance between the object and the instrument in accordance with the surface size.
Note: when you get the temperature that differs most to the surroundings, then you probably have got the right direction.
The measurement surface size related to the distance 8:1
Emissivity:
Set the coefficient for surface reflection factor (Emissivity factor) using the table below or check via a contact probe.
Select the item with (UP) and (DOWN) arrow keys.
Sound screen
Listening to a machine sounds enables analysis of gears and low speed bearings (<300 rpm) in an alternative way and can improve analysis
speed and quality. Viber X3™ makes it possible for the user to listen to the machine while at the same time seeing the vibrations in the
instrument display.
Note that you must choose the Vibration Screen while the sound is enabled the see the vibration signal.
When a headphone set is connected to the Viber X3™, the Sound Screen can be used to adjust the sound volume (depending on hardware
version there is also a volume control on the headphone cord). Before changing volume, the SOUND function must be ON. Sound output
status is enabled (ON) or disabled (OFF) in the Sound Settings menu.

8Howtointerpretvibrationlevels
Auserwithnopreviousexperience,shouldusetheISO10816-3standard.
Thestandardnormallycallsforavelocitymeasurementinmm/sRMS.To
better understand what this measurement means, think of it as how fast the
machine is moving back and forth. This measure gives a good understanding
oftheamountof“breakdownenergy”,causingmainlywearandfatiguein
the machine or the structure.
The instrument measures the total RMS vibration value in the frequency
range.ThisRMSvalueistheaveragesumofallthemeasuredvibrations.
Example:
Ifthesimultaneousvibrationcausedbyunbalanceis(4mm/s),bymisalign-
ment(2mm/s)andbythegearmesh(5mm/s)thenthetotalvibrationmea-
sured with VIBER X3™is6.7mm/s.
Noticethatareductionoftheunbalancefrom4mm/sto1mm/s
willreducethetotalvaluefrom6,7mm/sto5,5mm/s.
Total vibraon(RMS)=√4*4+2*2+5*5=6,7mm/s

TheISOstandard10816-3classiesmachinesdifferentlywhetherthemachi-
nesareconsideredasexibleorrigidmounted.Thisreectsthelocationof
the machines stiff-body resonances related to the basic running speed of the
machine.
Forinstance,amachinesupportedbyrubberorspring,haveresonancesat
low running speeds. The machine starts vibrate at certain low revolutions.
When the speed is increased above these resonance frequencies, the vibra-
tionisreduced.Thismachineisconsideredexible.
ModernmachinesthathavehighRPM’sandexiblebearingsupportsand
foundations,canbetreatedasexible,evenwhentheyaren’tmountedon
rubber or springs.

3.1 ISO standard 10816-3
The ISO standard 10816-3 classifies machines differently whether the machines are considered as flexible or rigid
mounted. This reflects the location of the machines stiff-body resonances related to the basic running speed of the
machine.
For instance, a machine supported by rubber or spring, have resonances at low running speeds. The machine starts
vibrate at certain low revolutions. When the speed is increased above these resonance frequencies, the vibration is
reduced. This machine is considered flexible.
Modern machines that have high rpm’s and flexible
bearing supports and foundations, can be treated as
flexible, even when they aren’t mounted on rubber or
springs.
Group 1:
Large machines with rated power above 300kW.
Electrical machines with shaft height H > 315mm.
Operating speed ranges from 120 to 15000 rpm.
Group 2:
Medium-sized machines with a rated power above 15kW up to
and including 300kW.
Electrical machines with shaft height between
160 < H < 315 mm.
Operating speed normally above 600 rpm.
Group 3:
Pumps with multivane impeller and with separate driver with rated power above 15kW.
Group 4:
Pumps with multivane impeller and with integrated driver with rated power above 15kW.
4Vibration analysis
4.1 Recommended vibration levels in mm/s and common findings
The list and table below can be used, as a first consideration, when you approach a machine newly commissioned or after
some time in operation. Investigate the reason for any machine that vibrates above 3 mm/s RMS. Do not leave levels
above 7 mm/s without analyzing consequences.
0 –3 mm/s | 0 –0,12 in/s
Small vibrations - None or very small bearing wear. Rather low noise level.
3 –7 mm/s | 0,12 –0,28 in/s
Noticeable vibration levels often concentrated to some specific part as well as direction of the machine. Noticeable
bearing wear. Seal problems occur in pumps etc. Increased noise level; try to investigate the reason. Plan an action during
next regular stop. Keep the machine under observation and measure at shorter time intervals than before to detect a
deterioration trend if any. Compare vibrations to other operating variables.
7 –11 mm/s | 0,28 –0,43 in/s
Large vibrations. Bearings running hot. Bearing wear-out cause frequent replacements. Seals wear out, leakage of all
kinds evident. Cracks in welding and concrete foundations. Screws and bolts are loosening. High noise level. Plan action
soonest. Do your best to reveal the reason. You are wearing down investments quickly.

9.1 Resonance
Aresonancecaneasilybefoundwhenaexiblemachineisrunningupor
downitsspeed.TheresonancefrequenciesarelocatedattheRPM’s,where
the vibration has a local maximum level.
To understand a resonance you can compare with the string of a guitar. The
string has its natural basic tone that will ring as soon as the string is struck.
The actual frequency of the tune depends on the stiffness and the distributed
mass of the string.
All machines have similar built in ”tones” with corresponding properties
consisting of stiffness and a mass in the form of mechanical strings such as
shafts,beams,oorsand in all mechanical parts. If anynaturalexcitation
(=alternatingforce)inthemachinehasthesameornearlythesamefrequen-
cyasaresonancefrequencythevibrationwillbeampliedinthismachine
part, and a much higher vibration level will occur.
To identify, measure the vibration levels in three perpendicular directions at
thebearings.Ifyoundameasurementwithatleastthreetimeshigherlevel
than in the other directions, consider resonance as a likely possibility. The
resonance is amplifying the mechanical force and thus gives a high vibration
in that direction. The resonance makes the machine unnecessarily sensitive
to mechanical forces.
Actions to handle a resonance are different depending on its location, opera-
ting conditions etc. It will normally require experience to alter the situation.
Onereasonisthatthemodicationcanaffectthebasicmechanicaldesign
of the machine and normally require the competence of a machine designer.
Werecommendhowevertoconsidersuchmodicationssincethechangeof
the resonance frequency normally is cheap compared to the high maintenan-
cecostthatwillfollowanyattempttorunamachineundertheinuenceof
a resonance.
Sometimesit´spossibletochangethespeedofmachines,whichoftenisa
simple solution.
