10 Introduction
BALTECH VP-3470
Operation manual
3. Safety measures
3.1. General provisions
BALTECH VP-3470 is a vibrometer balancer that can be used by any technician
who has received the training at the BALTECH training centre on the course TOP-
105 “Dynamic balancing of the rotors in the own bearings or on the balancing
machines” or TOP-103 “Foundations of the vibration diagnostics”. The instrument
should be used only for its intended purpose. Always observe safety precautions
according to ISO 20806-2007 “Mechanical vibration. Criteria and safeguards for the
in-situ balancing of medium and large rotors”.
Nonobservance of the safety requirements may result in serious injury, death or
failure of the instrument.
For this purpose:
• Do not use the instrument if there are any damages.
• Always use the instrument only for its intended purpose.
• Observe the safety regulations related to the operation of electrical installations.
The vibrometer-balancer BALTECH VP-3470 should be powered from the constant
low voltage generated by a network adapter or internal batteries.
Keep sensors and cables away from moving parts.
Safety measures 11
BALTECH VP-3470
Operation manual
It is strictly prohibited to use the instrument if the atmosphere contains more than
20 per cent of the lower explosive limit of a flammable or explosive substance.
3.2. Personnel safety
During the on-site balancing an operator should have safe access to moving parts to
install trial and correction weights on them. Strictly observe the safety instructions
specifying actions that allow safely stopping the machine operation and instructions
related to the use of auxiliary equipment, excluding its contact with rotating
components.
3.3. Machine operation mode during the balancing procedure
During the on-site balancing the machine starts up and stops repeatedly that can
cause excessive loads. In this case the machine operation requires a special analysis.
The example of this analysis is given in the Table 1 “Safety measures for some types
of machines”.
Repeated startups and stops may result in reliability degradation and service life
reduction of the machine.

performance fan
Some types of the electric motors are
allowed to be started up only a limited
number of times per hour. The speed takerup from zero to maximum amount can be
uncontrolled. Therefore the size of the trial
weights should be selected in such a way
that the machine can’t be damaged in case
of their installation in improper position.
Large fans High-performance
induced draft fan
The air current generated be the fan
during the balancing procedure should
be distributed properly. Sometimes it is
necessary to close the air valve which can
lead to a breakaway. The fluids fed by the
fan can be hot or contain harmful substances
therefore an operator should not access the
fan (to install the correction weight, etc.) till
the operation conditions are safe.

3.4. Laser safety
Example Safety measures
The above mentioned is related to the
turbines. To enable the access to the internal
correction planes it is sometimes necessary
to use air instead of hydrogen.
But for most generators the duration of run
and maximum rotation frequency are limited
when working in air medium even if there is
no voltage and load. These restrictions must
be observed during the balancing process.
Make sure that the seal is lubricated properly
when working in air medium. Dismounting
of some internal wind breaker plates can be
required to facilitate access to the internal
correction planes. Also make sure that
the dismounting will not cause significant
reduction in the quality of the generator
cooling.
According to the ISO 60825-1-2009 the tach used in the device bolongs to the 2nd
class of laser equipment. The tach is eqipped with a laser diode of capacity less than
1 mWt and wave length in the range 635-670 nm.
By operating the equipment you should follow special requirements:
- do not open the tach.
- do not observe laser light sources by the powered tach.
- do not direct a laser bearm in the eyes of others.
All repair works, which need the tach to be opened, should be performed only by
specialists of BALTECH GmbH.
3.5. Installation of trial and correction weights
When you add the trial and correction weights make sure they are fixed properly
and can withstand the developing centrifugal force. The correction weights should
not interfere with the normal machine operation. If the installation procedure of the
correction weights is specified in the manufacturer’s instructions, strictly observe
them.

5.1. Operation conditions
BALTECH VP-3470 is intended for use in laboratory and production environment.
It is strictly prohibited to use the instrument if the atmosphere contains more than
20 per cent of the lower explosive limit of a flammable or explosive substance.
Environment conditions:
• Environment temperature: 0…+40°C
• Relative humidity, by 25°C: ≤ 95%
• Atmospheric pressure: 84…106,7 kPa (630-800 mm Hg)
5.2. Preparation to operation
5.2.1. Unpacking and installation
Before you start operating:
• Check all the components for any damages and contamination. If necessary
perform actions described in the section 11 “Maintenance”.
Do not use the instrument if there are any damages.
• Check the delivery set according to the p.4.3. “Delivery set”
• Make sure that the battery is charged.
24 Operation conditions and prestarting procedures
BALTECH VP-3470
Operation manual
5.2.2. Accelerometer installation during vibration control
There are several methods of accelerometer installation but the most common
is mounting on a magnetic base, because this method is convenient and
ensures measurement reliability. The magnetic base allows firmly mounting the
accelerometer on a measurement object and performing measurements one-by-one
on several machines using one accelerometer. The mounting and dismounting of the
accelerometer with the magnetic base takes minimum time.
To ensure the reliable mounting of the accelerometer on the measurement object
make sure that the magnet is firmly installed on the surface of the measurement
object. The mounting surface should be 20х20 mm and free of dirt, corrosion and
flaking paint.
In some cases the sensor can be mounted on a stud or with a probe.
The sensor mounting on the stud ensures the best repeatability of the measurement
results, but this mounting method is less convenient (mounting and dismounting
require much time; the sensor cable can be damaged).
The mounting with the probe is used when other mounting methods are not available.
The measure points should be marked because even small displacement of the
sensor can lead to improper readings.
Operation conditions and prestarting procedures 25
BALTECH VP-3470
Operation manual
5.2.3. Installation recommendations
If you use the MEASUREMENTS program the measure points should be selected
according to the mounting method (Figure 7).
Figure 7. Mounting methods and measure points
a) Mounting on dampers with/without a subframe (Figure 7, a).
The measure points should be located on all the damper mounting bolts, from the
machine side, i.e. above damping, or on the machine bearing surfaces close to
these bolts if there is no way to mount the sensor on the bolts. If the machine has
a subframe, the measure points should be located directly on the points where the
machine is mounted to the subframe.
We recommend that you perform the measurement on the bearing units or as close
to them as possible.
The measurement should be carried out in every measure point in three perpendicular
directions: vertical, horizontal and axial. The technical condition is estimated based
on the highest vibration level.
b) Rigid mounting (Figure 7, б)
The mounting procedure is the same as above. The only difference is that depending
on a particular foundation design the measurements can be carried out only in one
26 Operation conditions and prestarting procedures
BALTECH VP-3470
Operation manual
or two directions where the foundation stiffness is the lowest.
If the foundation stiffness is much the same in all three directions, the measurements
should be made in all the directions. If the foundation stiffness is different in three
directions, the measurement can be made only in the direction of the lowest stiffness.
Moreover as opposed to monolithic structures the stiffness of the frame structures
in the horizontal and axial directions are usually much higher than in the vertical
direction. So the vibration levels can be higher in these directions than in the vertical
one.
Most attention should be given to the horizontal direction where the stiffness is lower
and there is always an internal source of dynamic forces generated be the rotating
rotor (as opposed to axial direction where high dynamic forces occur usually only
due to poor alignment).
Never install the vibration sensors on auxiliary production parts: slopes, shrouds,
etc. even if the vibration in these parts is the highest.
5.2.4. Accelerometer installation during the balancing and diagnostics
The measure points are selected based on the following:
а) First of all it is necessary to control the vibration levels on the bearing units
because they fully take the dynamic forces generated by the unbalanced rotor. As
a rule, the measurement directions are vertical and horizontal, i.e. radial to the
rotation axis. The balancing should be performed based on the measurement
results, in the points (and directions) of the highest vibration level;
b) Before and after the balancing procedure it is necessary to measure the vibration
according to the recommendations given in the p. 5.2.3;
c) Additional measurement points can be measured depending on the individual
requirements to a particular machine. If the vibration levels at the rotation frequency
in the axial direction are comparable or exceed the vibration levels in the radial
Operation conditions and prestarting procedures 27
BALTECH VP-3470
Operation manual
direction (vertical or horizontal) it is necessary first to align the shaft.
To perform the shaft alignment use only professional systems. We recommend
that you use the shaft alignment systems SA Series.
Always mark the measurement points and use them during the next measurements.
Otherwise the monitoring will be incorrect.
After the vibration sensor is mounted make sure that the cable connected to the
display unit is uncoiled!
Install the vibration sensors only on the grounded equipment!
There is settling time for accelerometer that should be taken in account to perform
accurate measurements. After placing accelerometer on the object wait 2-3
seconds then proceed with measurements
5.3. Laser tachometer installation
BALTECH VP-3470 uses a laser tachometer to detect the rotor rotation frequency.
The laser tachometer should be installed using a magnetic rack in compliance with
the safety measures. The laser beam line must be directed toward the rotor axis of
rotation. The permissible deviation of the laser beam from the normal to the rotor
surface is +/- 20 degrees.
28 Operation conditions and prestarting procedures
BALTECH VP-3470
Operation manual
The laser tachometer must be installed at a distance of not less than 0.1 m and
not more than 0.2 m.
Apply the reflective film (included in the delivery set) on the open area of the rotor.
Minimum angular dimension of the mark in degrees:
α
= Kα * n / 1000
min
where n – shaft rotation frequency, rpm,
K
= 3º - conversion factor
α
Minimum linear dimension of the mark in millimeters (when applying on the cylindrical
surface of the shaft):
L
=KL * n * D / 100000 L
min
where n - shaft rotation frequency, rpm,
D – shaft diameter, mm
K
= 2,618 rpm - conversion factor
L
Example:
If n = 9000 rpm and D = 120 mm, the mark length must be more than 28 mm
(27º). The width of the mark must be sufficient for convenient positioning of the
laser beam.
The laser beam of the tachometer must fall on the reflective film. During the shaft
rotation the tachometer will give an impulse when detecting the mark.
=KL * n * D / 100000
min
To set up the maximum sensitivity of the tachometer turn the shaft in such a way
that the mark doesn’t reflect the beam and press the button on the tachometer.
Hold the button till the status led lights up.
Operation conditions and prestarting procedures 29
BALTECH VP-3470
Operation manual
Before you start measuring make sure that the tachometer catches the marks stably.
If you use the tachometer for the phase detection (during the balancing) note the
following:
Do not touch the installed tachometer till the balancing procedure is completed.
If the tachometer is moved during the balancing, all the measurements must be
carried out all over again.
5.3.1. Angular marking of the rotor
Angular rotor marking should be performed according to the defined direction
(towards/against rotation).
The angular marking is made according to the direction defined in the balancing
parameter settings (towards/against rotation).The first mark can be located at any
place. An operator can decide himself how to apply the mark on the rotor: it can be
an angular mark from 0 to 360°, or sequential numbering of blades (for example,
on a fan) or holes on the rotor coupling etc. (Figure 8).

weights and spare weights for the balancing purpose. In this case we recommend
that you use them.
It is especially related to heavy electrical machines, for example, turbine electric
generators.
However in most cases a user can produce the correction weight himself depending
on the design of the balancing plane. If the machine doesn’t have a balancing plane
then one can use some available parts of the rotor.
For example, half couplings can be used as balancing planes. As for pumps,
exhausters and similar machines the correction weights can be installed on blades
and turbine discs. In some cases one can use so called technological planes that are
mounted on the rotors for the balancing purpose. They are removed and a required
correction weight is mounted (e.g. welded) on the rotor. Further the technological
plane is used to perform the balancing of a similar machine. The Figure 9 and Figure
10 show the most common correction weights and installation methods.

5.3.3. Digital angle gauge
The maximum delivery set of BALTECH VP-3470 contains a digital angle gauge,
which allows measuring angle of rotation of the parts with a horizontal axis of
rotation. The appearance of the angle gauge and its control elements are shown
on the Figure 11.
Figure 11. Angle gauge

2. LCD display
3. Zero button
4. Magnet base
How to use the angle gauge for detection of the installation place of the correction
weights:
1. After the installation place of the correction weight is calculated and determined it
is necessary to turn the correction weight in such a way that the installation place of
the trial weight (zero angle) is in the location convenient for installing the correction
weight.
2. Mark the position of the test weight on the stationary part of the machine using
a chalk or marker.
32 Operation conditions and prestarting procedures
BALTECH VP-3470
Operation manual
3. When installing the angle gauge following two conditions must be observed:
a) The front plane of the angle gauge must be perpendicular to the rotor rotation
axis;
b) In any rotor position the indicator of the angle gauge must be always available
for taking the readings.
4. Switch on the angle gauge by pressing the Power key. Use 0 to reset the readings.
5. The angle gauge shows angles in the range ± 180º. If the calculated angle is less
than 180 degrees, rotate the rotor against direction of rotation till the angle gauge
shows the result. The place of installation of the correction weight will be opposite
to the mark on the stationary part of the machine (p.2).
6. If the calculated angle is more than 180 degrees, the rotor must be rotated
towards direction of rotation by 360°C- Fnominal, where Fnominal is the angle
position value of the correction weight. The place of installation of the correction
weight is opposite to the mark on the stationary part of the machine (p.2).
When using the digital angle gauge always observe the safety measures.
5.4. Power connection
BALTECH VP-3470 is powered from four LiFePO4 batteries that are installed in the

9.4. Inuence Coefcient Method (ICM)
The ICM is a proportionality coefficient between the vibration and unbalance.
Balancing 77
BALTECH VP-3470
Operation manual
The ICM allows performing balancing of the rotors within one run which considerably
facilitates the balancing procedure. Besides, ICM makes it possible to evaluate the
dynamic forces occurred in the rotor supports, based on the vibration levels. Though
machines of the same class can have different ICM, deviation from the average
values are within the limits that make it possible to perform the rotor balancing.
To receive the ICM perform the balancing according to the p. 9.1.”New balancing”
and then perform the following:
1. Activate ICM and press Enter (Figure 81).
