Chapter 5 - Balancing Measurements
8.
When the marker appears to be frozen, press <STORE>.
9.
Adjust the plane 2 phase to the zero mark or reference mark as before.
10. Press <STORE> to complete plane 1 measurement and begin plane 2 measurement.
11. Adjust the strobe flash rate to match the machine speed, as described earlier. When the
marker appears to be frozen, press <STORE>.
12. Adjust the plane 2 phase to zero or to the reference mark you used before. Press
<STORE> to complete the trial measurement for plane 1 and plane 2.
13. Shut down the machine and remove the trial weights from the both planes. Continue the
balancing procedure in the next section.
Adding the Correction Weights and Taking a Residual Measurement
1.
Attach correction weights. The dataPAC calculates and displays a recommended
balancing weight labeled “Correction” on the dataPAC display. There are two
correction weights, one for each plane. The “Position” column indicates where to attach
the correction weight.
z
For rotors with zero positions, the position is shown in degrees, in the direction of
rotation set in Weight Placement, from the 0° mark.
z
For rotors with multiple “positions” or vanes, the Position column indicates on
which positions the weights must be added. The 0° position is considered position
1, and the other positions are numbered sequentially, in the direction of rotation.
Prepare the prescribed balancing weight and attach it to the rotor. Make sure you attach
the weight the number of degrees or positions, in the direction of rotation set in Weight
Placement, away from the reference mark.
You may toggle between Dynamic or Static/Couple corrections by pressing <F2>. In
Static/Couple display mode, the correction and trim weights are displayed as a static/
couple weight pair.
Additionally, the dataPAC calculates the amount of weight that might be removed, if
weights are already attached to the rotor. Press <F3> to toggle between Remove Weight
and Add Weight.
