A4300 - VA3 - Balancing
Notice: Push Setup button to recall the trial mass input dialog box and change trial mass value if
necessary.
The result amplitude/phase measurement is displayed.
Remove trial mass and mark its position (it represents 0 degrees). From this position will be
calculated the result balancing mass. A positive angle is orientated in the rotation direction.
In the result field read the balancing mass solution value and angle value for its installation. Install this
mass to required position.
In the example on the screen:
st
The 1.403 mil 0-P amplitude was measured at 1201 RPM (it is 0.08% higher speed then in 1
RUN).
The result mass is 0.358 oz and the position is 23.4 deg from trial mass position in opposite rotation
direction.
TEST MEAS.
Push PgDn and test. meas screen appears. Press START and run the test measurement. The result
is the vibration amplitude after balancing. If this value is sufficient then the balancing process is
finished. If the value is still high then in the TRIM #1 field the next balancing mass and angle is
displayed. Install TRIM #1 mass and repeat test measurement in next screen (PgDn) as TRIM #2, #3
...
Notice: Don't remove any formerly installed weights now!
In the example on the screen:
The 0.136 mil 0-P is an amplitude reduction of –88%. It means machine condition is much better then
before balancing. If this result is not acceptable then install next TRIM #1 mass (0.043 oz/-94.4 deg).
The angle is related always to trial mass position.
Dual Plane balancing
In two planes you can balance with one or two vibration sensors. In case of one sensor you will need
to move the sensor from one plane to the other. The balancing process takes more time.
Recommendation: If you balance with two sensors, it is recommended in project definition to enter
Channel parameter equal CH2. This channel will be assigned to the left plane. When you select CH2
