Chapter 5 - Balancing Measurements
5.
When the marker appears to be frozen, press <STORE>.
6.
Adjust the plane 1 phase to zero or a reference mark as before.
7.
Press <STORE> to complete plane 1 measurement and begin plane 2 measurement.
8.
Press the trigger on the strobe.
9.
Adjust the plane 2 machine speed. Adjust the strobe flash rate to match the machine
speed, as described earlier. When the marker appears to be frozen, press <STORE>.
10. Adjust the plane 2 phase to zero or a reference mark as before. Press <STORE> to
complete the residual measurement for plane 1 and plane 2.
11. Shut down the machine and attach the trim weights whose weights and positions are
indicated on the dataPAC display.
Note:
Do not remove the original correction weights.
12. Continue to trim-balance the machine as required. After securing the trim weights,
bring the rotor up to speed and repeat the measurement. The dataPAC takes vibration
readings, calculates new trim weights, and displays them as described above.
If the vibration has been reduced to an acceptable level, balancing is complete. Save
your balancing data, if desired, by pressing <SHIFT><F5>. The Save Balancing Data
window appears. Enter the file name. When your entry is complete, press <DONE>, or
press <SHIFT><F5> (Abort) to cancel the entry. If the rotor is still out of balance,
repeat trial weight addition as many times as necessary until the rotor is properly
balanced.
One Plane Balancing with a Reference Trigger
This section discusses the procedure for balancing a machine in one plane using the
dataPAC and an attached reference trigger, such as a laser tachometer. This procedure is
divided into parts based on when you start and stop the machine. You must complete the
entire procedure until the vibration level has been reduced enough for your needs.
Setting Up the Entach Digital Laser Tachometer
If you are using the Entach tachometer, you choose a measurement mode before using the
tachometer as a reference trigger. The Entach has several measurement modes. For
balancing applications with the dataPAC, use the RPM measurement mode.
When you connect the tachometer cable to the dataPAC, the Entach automatically switches
on.
Refer to the Entach Operating Guide for more information about using the Entach digital
laser tachometer.
