Safety measures 11
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.

12 Safety measures
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.

Safety measures 13
Table 1. Safety measures for some types of machines
Machine
class
Example Safety measures
Turbines Steam or gas turbine Stop the machine to add a correction weight
and apply a phase mark. Make sure that the
shaft is not bent. For this purpose rotate the
shaft for a time to achieve the temperature
equalization.
Electric
motors
Motor for
high
performance fan
Some types of the electric motors are
allowed to be started up only a limited
number of times per hour. The speed taker-
up 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.

14 Safety measures
BALTECH VP-3470
Operation manual
Machine
class
Example Safety measures
Electric
generators
The electric
generator with
hydrogen cooling and
drive from steam or
gas turbine
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.
3.4. Laser safety
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.
