Prerequisites
- Complete the
Job Setup,
Acquire Data, and
View Balance Correction steps.
- Attach one or more
vibration sensors and the tachometer to the analyzer.
- If you use more than one
sensor and do not use the CSI 2140 Four-Channel Input Adapter, ensure you
connected the proper cables before collecting data. Collect the measurement for
the appropriate input.
CAUTION:
Follow proper safety and
equipment lock out procedures when working around rotating equipment. Acquire
data from the specified location for the highlighted measurement point. If you
assign data from other measurement points to this location, you invalidate all
calculations.
Procedure
-
From the
Balance main menu, press
.
If you loaded the balance job from AMS Machinery Manager
for a one-run balance, the
Applied Weight option is disabled. Proceed to
step 4.
-
Enter the amount and location of the trim weight correction for
this trim run, and press
Enter.
In
Advanced Balance mode, use this data for later
reference and to estimate residual vibration.
Tip: After you select the weight plane or location, use
the up, down, right, and left arrow keys on the analyzer to scroll through the
fields in the table.
-
Press
F4 Acquire Trim Data.
-
Place the sensor at the location specified for the measurement
point.
-
If you set up multiple speeds, select the appropriate speed.
-
Use the up and down arrow keys to select the measurement point.
If you defined only one measurement point and speed for the job,
the
Select Measurement Point screen is not
displayed and the data acquisition begins automatically.
-
Press
Start Data Acq to collect data.
Collect data until the magnitude is stable and phase varies
by no more than 5 degrees in the Data Stability graph.
-
Press
Accept Data.
-
Repeat the steps above for all measurement points for all trim
runs.
If you select Auto for the mux option, the Balance program
automatically accepts the data and moves to the next point when the phase and
magnitude are good for 3 consecutive averages. See
Set the mux option.
-
Press
Next Step to review the data.
Review the data on the
Tolerance Check screen and ensure the vibration
is within the balance specification.
-
Press
Enter.
If you have multiple planes, press
Enter to view the
Tolerance Check screen for each plane. The
Acquire Trim Data step is completed.
-
Press
Next Step.
Results
You must complete the
Applied Weight,
Acquire Trim Data, and
Tolerance Check steps to complete a trim run and
store the data to the job. If the X does not appear on the
Balance main menu, the analyzer did not save the
data, and you cannot transfer the data to AMS Machinery Manager.
