Procedure
1.
From the Balance main menu, press F3 Job Setup > F11 Speed Setup.
2. Set the following options as necessary.
Option Description
F3 Delta RPM Enter a number between 0 and 500 to set the valid running speed range for
all speeds. Enter 0 to disable this option. For example, if you enter the
equipment speed of 1,800 RPM and a Delta RPM of 50, the valid range for the
running speed is between 1,750 and 1,850 RPM. When the speed is outside
the range, the analyzer displays the RPM, but not the amplitude and phase.
The invalid readings are not used to compute the averaged magnitude and
phase readings during data collection. The default is 0.
F4 Enter
Speed #1
Enter a number between 0 and 100,000 for the equipment speed. If you
enter 0, “Unknown” displays for the speed.
Note
Additional keys appear based on the number of speeds you defined in F9
Number of Speeds. The default is Unknown.
F9 Number of
Speeds
Enter up to six equipment speeds. The default is 1.
Note
The number of measurement points multiplied by the number of
measurement speeds cannot exceed 24.
3. Press Enter.
9.4 Sensor Setup
Sensor Setup lets you select a sensor type and its parameters in Basic and Advanced Balance
mode. You can also set up the bandwidth or the runout measurement.
9.4.1 Sensor locations
If you have only one weight plane, place a horizontal and vertical sensor at each bearing
supporting the rotor, especially for overhung rotors. If you use only one sensor per
bearing, place the sensor at the same horizontal or vertical orientation to make it easier to
compare the data from all planes. You get the best results by taking measurements at
both bearings. For single-plane jobs, place both sensors at one bearing.
