Rotor balancing
Transducer selection and speed measurement
The balancing procedure is menu guided. Select
the method, then simply follow the instructions
on the instrument screen.
The first steps are common for all methods. Start
with selection of transducer. The transducer
selected under ‘Transducer register’ will be
displayed as default.
Follow the setup guide by pressing the F2
function key (Next).
For the ‘4-run’ method, the RPM data are only
needed to find the 1X position in the spectrum
and thus check on the amount of unbalance.
You can do balancing work in three ways (1);
without the RPM, input it via the numbers pad
(Preset), or measure it.
Select ‘Portable’ RPM transducer when using
the Tachometer probe TTP10 or ‘Remote’ for
transducers of type PNP, NPN or Keyphasor.
When Leonova is connected to a stroboscope,
the setting is normally set to NPN. Some types of
stroboscopes require the setting of ‘12V Supply’.
RPM can be measured with two methods (2);
synchronized (recommended) or asynchronized.
‘RPM synchronized’ means that each measure-
ment starts in exactely the same shaft position.
‘Asynchronized’ only require one reading and
is a quicker way of measuring RPM.
The ‘2-run’ method is automatically set for
synchronous RPM measurements, see previous
page. You can input the number of synchronized
readings (3), recommended are 10-20. If the
machine is severely unbalanced you might
increase the number of synchronized readings
even more.
