Portable field balancer "Balanset-1A"
Balanset-1A is portable dynamic balancer used to balance rigid rotors in their own bearings (in-situ) or as
measuring system in the balancing machines.
It provide single- and two-plane dynamic balancing services for fans, grinding wheels, spindles, crushers,
pumps and other rotating machinery. Balancing software provides the correct balancing solution for
single-plane and two-plane balancing automatically.
Balanset-1A is simple to use for non-vibration experts.
Balancing procedure uses 3-run method with adding the test mass in every place of balancing (Influence Coefficient Method).
Software calculate balancing weghts and place (angle) automatically, show it in the result table and save in archive file. Also you can print balancing report.
Waveform and spectrum of vibration charts are possible.

2. Prepare to work. Software and hardware setup for two-plane balancing.
2.1 Driver installation
Install drivers and Balanset-1A software from installation flash disk.
Insert USB cable to computer USB port. Interface module supplied from USB port.
Use shortcut to run the program.
2.2 Sensor installation
Install sensors as shown on the fig. 1,2,3
- vibration sensors to connectors X1 and X2
- phase laser sensor to connector X3
fig.1 Two-plane balancing scheme
Install reflector mark on the rotor and check RPM value on the phase sensor when rotor rotate.

3. Balancing procedure
fig.3 Main window for two-plane balancing
After sensors install click on "F7 - Balancing" button and set balancing parameters. Then click "F9-Next"
fig.4 Balancing settings
Then make step-by-step operations as shown in the Table 1 below.
Table 1. Step-by-step operations
Run#0 - Start-up without test weight.
2. Run the machine at
its operating speed (be sure that operating speed is far from resonance frequency of construction)
3. Click on F7-Run#0 and measure the vibration level and phase angle in turn without test weight.
Duration of the measuring process may amounts 2-10 sec.
fig.7 Two plane balancing window. Original vibration
Run#1 - Test weight in plane 1
4. Stop the machine and mount a test weight of suitable size arbitrarily in plane 1.
5. Start up the machine, click on F7-Run#1 and measure the new vibration level and phase angle. Duration of the measuring
process may amounts 2-10 sec.
6. Stop the machine and remove the test weight
Run#2 - Test weight in plane 2
7. Mount a trial weight of suitable size in plane 2 .
8. Start the machine again, click on
F7-Run#2 and measure the vibration level and phase angle once more.
9. Stop the machine and remove the test weight
Step 4 - Calculation
10. The values of the correction weights and angles required will be calculated automatically
and shown in polar diagram.

fig.5-1 Two plane balancing. Correction weights fixed position, polar diagram
fig.6 Two plane balancing. Correction weight mounting
11. Mount the correction (balance) weights at the positions
indicated in popup form at the same radius as the test (trial)
weights (as shown in the figure in right column).
12. Start up the machine again
and measure the amount of residual unbalance in the rotor, to see how successful
the balancing job has been.

4. Other features
4.1 Vibrometer mode.
To select Vibrometer mode click "F5- Vibrometer" button in the main window
for two-(one-) plane balancing To start the measuring process click "F9-Run"
V1s (V2s) - summary vibration in plane 1(2) (mean-square)
V1o (V2o) - 1x vibration in plane 1(2)
In the right side you can see spectrum window.
Measuring data files can be saved in archive.
4.2 Influence coefficients
If you save the results of previous balance, you can balance the machine using saved balancing coefficients.
Select "Saved coefficients" in the "Balancing settings" window (fig.4) and click "F2 Select" button to choose previous machine type from list.
To save coefficients after balancing click "F8-coefficients" in the balancing result pop-up window
(see Tab.1) and then click "F9-Save" button. Input machine type ("Name") and other information in the table.
4.3 Archives and reports.
To save balancing information click"F9- Add" to archive
in the balancing result pop-up window (see Tab.1). Input machine type ("Name") and other information in the table.
To open previous saved archives click "F6-Report" in the main window.
To print report click "F9-Report"
Two planes balancing archive.
To view charts of vibration click on "F8-Diagrams"
Three kinds of charts are available "Common vibration","Vibration on rotor revolution frequency 1x vibration" and "Spectrum"
(for example, for 3000 rev\min frequency is equal 50Hz)
