Balancing Application
Refer toTo Split the Correction Weight on page 230
for details.
9.
Shut down the machine and attach the trim weight(s) whose weight, angle,
and radius are indicated on the screen.
10.
Start the machine and let it reach operating speed.
11.
Press READ/OK. The Enpac 2500 takes vibration readings, calculates
new trim weight(s) and displays it as described above.
12.
If the rotor is still out of balance, repeat adding the trim weight and taking
residual measurements until the rotor is properly balanced. If several trim
correction runs have been performed (resulting in several trim weights),
values may be combined into one permanent trim weight.
See Combining Weights Screen on page 235
.
Note that if the balance never improves, check to see if you entered the
correct trial weight size and location, or check other factors such as
misalignment or a faulty bearing.
13.
However, if the vibration has been reduced to an acceptable level,
balancing is complete. Save your balancing data, if desired, by pressing F3
(Memory).
Refer to Saving a Balance on page 236
for details.
IMPORTANT
Do not remove the original correction weight.
