VIBXPERT II Balancer 05.2012
Foreword
Congratulations! And thank you for choosing VIBXPERT II Balancer,
one of the most powerful balancing and vibration analysis equipment
from PRÜFTECHNIK.
This specially for field balancing designed instrument is based on the
VIBXPERT II platform, which is used worldwide by many technicians
for mobile data acquisition and signal analysis.
The 'Balancer' is distinguished by its efficiency and ease of use. The
measurement process implemented in the instrument is based on the
well-known "influencing coefficients method" and has been optimized
by a new knowledge-based algorithm. In addition to the balancing
procedure, VIBXPERT II allows vibration analyzes, resonance tests
and phase measurements to support the diagnosis of an imbalance
and to determine the optimum operating conditions for the rotor.

Safety and operating notes
Read this section carefully, paying especially close attention to the
safety notes, before working with the device.

General safety
The following notes must be carefully read and completely under-
stood before the device is put into service.
• Theapplicablesafetyregulationsmustbeobservedwhenper-
forming measurements on running machines.
• Installthemeasurementequipmentproperly.Duringmeasurement
on machines with rotating parts exposed, ensure that no brackets,
cables can become caught in rotating machine parts.
• Whenassemblingmeasurementcomponents,makesurethatno
holders, cables, etc. project into the range of movement of rotat-
ing machine parts.
• The respective manufacturer's instructions must be followed
when mounting balancing weights.
Make sure that attachment points for balancing weights to be
welded on are clean; clamp the ground electrode of the welding
device onto the rotor and not onto the machine.
For balancing weights that need to be screwed on, the maximum
permitted RPM of the motor must be observed.
• Themachinemustbedisconnectedinordertoworkontherotor
and must be secured against being switched on again in accor-
dance with the applicable regulations.
• Beforetherstmeasurement(initialrun),ensurethattheprepa-
ratory activities have been carried out correctly and completely.
In addition to the assembly of measurement components, par-
ticular attention must be paid to the correct input of parameters
in the machine setup. If an incorrect rotor mass is entered, a trial
weight that is too large may be calculated as a result. This could
have serious consequences for personnel and machine!
• Nooneisallowedtoremainintheradialvicinityoftherotordur-
ing balancing runs. This area must be properly secured against
unauthorized entry. If the trial weight of the rotor on a running
machine detaches, there is a risk of fatal injury in this area!

Intended use
VIBXPERT may only be used for the measurement of machine signals
in industrial environments while taking into consideration the techni-
cal specifications (see "Appendix - Technical data").
Transducers and cables may be used only for their respective intended
uses as defined in the corresponding sales leaflets.
VIBXPERT is intended for use as a portable balancing device for the
balancing of stationary machines equipped solely with rotating compo-
nents (rotors), e.g. turbine rotors, inductors, circulating pumps, cen-
trifugal compressors, fans, etc. This does not include machines with
oscillating components, e.g. all reciprocating machines.
VIBXPERT can be used without any restrictions for the balancing
of rigid rotors. Elastic (soft) rotors may only be balanced with VIB-
XPERTattheresonantfrequency(±25%)byanexperienceduser.The
measurement instrument and its accessories may only be operated by
authorized personnel.
Any other use shall not be considered an intended use and is im-
permissible. Incorrect or impermissible use and failure to observe
the instructions in this manual result in a loss of warranty from
PRÜFTECHNIK.
Environmental influences
Portable radio-based devices can interfere with proper functioning of
the device when operated nearby. In case of doubt, check the cable
between the device and its transducer.
Keep the protective caps on the connector sockets when they are not
in use to keep them clean.

Digital
Theyellowchannelisusedasthe:
- Input for digital signals from a trigger or a RPM sensor
- Serialinterfacefordatatransmission(RS232)
- Output for stroboscope control (TTL signal)
Thepermissiblerangefortriggersignalsis:
-26V...0V(negative)or-5V...+26V(positive).

     max.-10Vfalling
The input signal must not exceed the switching threshold of the
positive and negative range as otherwise incorrect measurements
can occur.
Temperature
This interface is used for the connection of a thermo couple type K.
