Select the Preferred Balance Mode

Before defining your first balance job, use the Balance Options menu (shown below) to decide which mode of operation you want to use.

6

Balance Mode Select option OverviewThis option allows you to select either of two balance modes, Basic or Stan-dard. The Standard mode is the recommended mode of operation allowing full utilization of all features offered by FAST Bal I/II.

The Basic mode offers a simplified setup but reduced flexibility and fea-tures. However, for many users, this may satisfy their needs and be the pre-ferred mode of operation. Select (8) Balance Mode Select to bring up the following screen.


1-13

7

Highlighting Balance Mode and pressing any key allows you to toggle between either of two balance modes:

• Standard – see previous explanation.

• Basic – see previous explanation.

When Basic is displayed, you are also asked to specify this information:

• Reference Loc – this is the preferred location on graphic plots for the 0° reference point. Use any key to toggle between Top, Bottom, Left, or Right. The location will be identified with a “T” on graphic plots (signifying the Tach reference position). This setting is for your convenience only and will not affect the calculated solutions.

NoteA job defined as Basic can be upgraded later to Standard by changing this setting. However, you must then go through the normal Job Definition screens before proceeding. A job defined as Standard cannot be changed to Basic without having to define a new job.

The trade-off for using the simpler Basic mode is the loss of some features available when using the full Job Definition of the Standard mode.

• Limited to 2 planes, 2 sensors, and 1 speed instead of 4 planes, 8 sen-sors, and 6 speeds.

• Automatic checking of data between sensors for structural flexibility/resonance is disabled (FAST Bal II feature only).



• Automatic splitting of weights for discrete weight planes is unavail-able.

• Estimate Trial Weight and calculate Amplification Factor/System Lag is unavailable. (FAST Bal II feature only).

• Customized Measurement Point labels and identification of sensor position is unavailable.

Define the Default Balance Sensor

From the Options menu, use the Default Sensor Setup function to define the standard sensor, vibration units, and MUX setting to be used. The Standard mode allows you to modify these settings any time a new job is defined. The Basic mode, however, uses the settings defined here. Changes to these set-tings only affect jobs created after the changes are made.

For detailed information about these settings, see the FAST Bal User’s manual provided with this package.

8

The AUTO setting is only available with the FAST Bal II package. Set MUX Enabled to ON or AUTO only if using the CSI Model 642 (2115/2117) or 648 (2120) 4-channel multiplexer. The AUTO function automati-cally acquires data for all defined MUX channels after channel one data acquisition is initiated.

When using AUTO, if the data does not stabilize enough for the program to automatically accept it, use the Enter key to over-ride.


1-15

Recommended Setup For the Balance Job

Most balancing jobs have either one or two planes (called weight planes) in the rotor where weight corrections are made. The rotor is typically sup-ported by two bearings. In these situations, place two vibration sensors at each bearing with approximately 90° between them. Use horizontal and vertical positions if possible. If you are using the Basic mode, place one sensor at each bearing.

With its mounted sensors, each bearing constitutes one measurement plane. If these recommendations are followed, the setup to supply data to the FAST Bal program will be either:

• 1 Weight Plane with 2 Measurement Planes and 4 Sensors or,

• 2 Weight Planes with 2 Measurement Planes and 4 Sensors.

If you use a phototach, place a piece of reflective tape on the shaft or rotor. Then, position the phototach where it responds (the red light on the back of the phototach lights up) as the tape passes the location of the vertical or the horizontal vibration sensor.

This is strictly for convenience – any position will work if necessary.

Using FAST Bal I or FAST Bal II

Both programs use the same basic flow and require the same set-up data. The most visible difference is that FAST Bal II uses numerous graphical displays for feedback, whereas FAST Bal I is entirely text based. There are several other features, such as special calculations and data checking which may not be as obvious; check the feature comparison table at the end of this document for a complete list of differences.

FAST Bal I/II is designed to lead you through all necessary steps. Just Begin with step 1, Job Definition and let the program lead the way. If addi-tional assistance is needed at any point, press the Help key if using the 2120, the Alt key if using the 2117, or the Keypad key if using the 2115 for a help message related to your current task.

1.····Define The Balance JobFAST Bal I FAST Bal IIBegin by defining the balance job; press Enter to select highlighted selec-tion.


1-17

The initial job definition screen primarily allows you to enter descriptive information that is used for labeling reports and for job storage. Use SPEC to specify what vibration level is considered acceptable. Use the Up/Down Arrow keys to move between fields. Press Enter to accept all changes and move to the next screen.



Job Definition (continued) – Basic Balance Mode

NoteThis feature is the same for both FAST Bal I and FAST Bal II.

After accepting the Job Definition screen, the following screen is displayed.

9

Explanations of the two options are:

• Configuration – use any key to toggle between 1 plane 1 sensor, 1 plane 2 sensors, or 2 planes 2 sensors.

• Rotation Dir – use any key to toggle between CW (clockwise) and CCW (counter clockwise). This is the direction of rotation at the end considered by you to be the reference end. Your choice will affect the orientation of graphics plots.

The program automatically labels the two sensors as IB (for inboard) and OB (for outboard) bearing. Use of the Horizontal or Vertical position is up to you. The best results will usually be obtained by measurements at both bearings.

The balance sensor and MUX definitions are the same as the setup speci-fied for the Default Balance Sensor option (accessed by using the Options key). If a different setup is desired, it must be defined before the new job is created. When using the MUX, the IB sensor is channel 1 and the OB sensor is channel 2.

Job definition for the Basic balance mode is now complete!


1-19

Job Definition (continued) – Standard Balance Mode

FAST Bal I FAST Bal IIThe next screen provides the information needed to create a data matrix for this job. See “Recommended Setup For the Balance Job” on page 1-15 for an explanation of the entries for planes and points. At Discrete Weight Positions, answer Yes if any of the weight correction planes have a number of fixed positions for weight placement.

The location of all sensors relative to TDC (top dead center) is requested (this information is used to record the setup and for special calculations). Please note that all angles are measured against the direction of rotation. For the machine shown in “Example Machine with Two Measurement Planes and Two Weight Planes” on page 1-15, the Tach pick-up is 90° from TDC. The DIRection OF ROTATION is used as a default for any graphic displays or graphical print-outs (it does not affect the calculations).

DELTA RPM is the RPM value which will be added to and subtracted from the reference balance speed to establish a window for valid data. Enter “0” at Delta RPM to disable this function.



FAST Bal I FAST Bal II• Describe the vibration sensor which will be used for all measure-

ments. If the CSI 642 MUX (or 648) is used, set MUX ENABLED to ON.

Describe the measurement positions which will be used for data acquisi-tion. Measurements at the same bearing should be designated as having the same measurement plane. Enter three characters/numbers to be used as the ID for each measurement location. Enter the angle of each sensor from TDC (see example machine in “Example Machine with Two Measurement Planes and Two Weight Planes” on page 1-15). When used with the Model 642/648 MUX, the channel number controls the MUX.


1-21

Use the graphics with FAST Bal II to verify the accuracy of the set-up infor-mation. Compare these screens to the machine in “Example Machine with Two Measurement Planes and Two Weight Planes” on page 1-15.



FAST Bal I FAST Bal IIWhen discrete weight planes are specified at the second job definition screen, the following additional screens will be displayed. Enter the number of available weight positions and the angle of position 1 from the tach reference (reflective tape, keyway, etc.). Be sure to tell FAST Bal which direction the positions are numbered relative to rotation.

If one of the available weight planes is continuous (weight may be placed at any angle or at irregularly located positions), then enter “1” for Weight Positions. All other entries for this plane can be ignored.

NoteThe remaining screens are similar for both the Standard and Basic balance modes except where features are not supported under Basic mode.


1-23

2. ···Make Measurements

FAST Bal I FAST Bal IIWhen the job definition has been completed, the program returns to the Balance Functions menu. Job Definition is marked as complete ([X]) and the next logical step is highlighted. Simply press Enter to proceed.

A list of the data runs required for this job is shown. Choose the Reference Run to acquire data “as is”, before any changes are made.



You are shown a list of the measurement points (MPT's) which were defined. Highlight any point and press Enter to begin data acquisition (ensure that the correct sensor is connected before pressing Enter). If you are using a 642/648 MUX, before beginning, connect all cables and the software will select the assigned channel.

NoteFAST Bal I shows instantaneous information on the left side of the screen and averaged data on the right. FAST BAL II dis-plays the instantaneous RPM, average magnitude, and phase as text.


1-25

FAST Bal I FAST Bal IIData acquisition screens for both programs are shown below. Allow the data to stabilize before pressing Enter to accept a measurement. This means getting to the point where there is less than 5° variation in the average phase and less than 10% variation in the average amplitude. FAST Bal I shows instantaneous information on the left side of the screen and averaged data on the right. Fast Bal II displays the instantaneous RPM, average magni-tude, and phase as text. The graphical display for FAST Bal II shows the instantaneous vector as a line with a box at the end. The line drawn to each side of the instantaneous vector shows the minimum and maximum vector plotted. The small cross-hair on the plot represents the average phase and amplitude vector.

You are returned to the Select Measurement screen after each measurement is completed until data has been acquired for all points. At that time, PROCEED TO NEXT STEP is highlighted. To repeat a measurement, use the Up/Down arrows to highlight the point of interest. Otherwise, press Enter to proceed.



FAST Bal I FAST Bal IIFAST Bal continues to lead you through the balance procedure. Next, a test weight (trial weight) must be added (or removed) at one weight plane and new measurements acquired.

Before acquiring data, you must tell the program how much and where weight was added. Up to two weights can be specified in one plane. Please note that P1(D) stands for plane 1, discrete weight plane. Locations for dis-crete weight plane weights are preceded by “@” and are given as a position number. The units of weight (ounces, grams, etc.) must be consistent throughout the procedure. Discrete weight plane are not supported in Basic mode. See next page for comments about the continuous weight plane.

Measurements are acquired using the same process as for the reference run.


1-27

FAST Bal I FAST Bal IIComplete all remaining trial runs using the same procedure.

A new weight must be added in a new weight plane for the next trial run. Either remove the previous weight or be sure it is also listed for this trial run. The P2(C) indicates that weight plane 2 was defined as continuous. Therefore, all positions are entered as angles (in degrees as measured against rotation from the leading edge of the reference mark).

All measurements are completed as before.



3.····Calculate And Install Correction Weights

FAST Bal I FAST Bal IIWhen all measurements are complete, the Balance Functions menu is dis-played with the next step, Correction Weights, highlighted. This selection will calculate the balance solution after the Reference and Trial Runs have been completed.

Just as when entering the trial weights, the solution for the discrete weight plane, P1(D), is shown as a position number. The solution for the contin-uous weight plane, P2(C), is shown as an angle in degrees. Notice the dis-crete weight solution is split between the available positions. Remember, the Basic mode always uses continuous weight planes.

Pressing the Page key (2115/2117) or the Page Up key (2120) will toggle between a solution adding or removing weight. Use the Up/Down arrow key to toggle between a solution with trial weights (TW) removed or the last trial weights left in place.


1-29

4. ···Check Result / Trim Run

FAST Bal I FAST Bal IIAfter the correction has been made, you should acquire data from the new condition to check the results. If the vibration has not been reduced suffi-ciently, then a trim calculation can be made to improve the balance further.

Enter the correction weights which were actually applied. Many times this will differ somewhat from the calculated solution due to various constraints.



FAST Bal I FAST Bal IIFAST Bal II can estimate the Residual Vibration from the Applied Weights screen. The accuracy of this calculation varies with the linearity of the system. Any factor affecting data accuracy and repeatability will also influ-ence the result.

Check the results by selecting CHECK RESULT from the Tolerance Check/Trim menu.


1-31

Data acquisition proceeds as before until all measurement points have new data.



FAST Bal I FAST Bal IIWhen data acquisition is completed, the results are summarized. The FAST Bal II graphic shows the original data at the MPT symbol. Up to two of the most recent check runs are plotted at the other end of the lines. The circle at the center of the graphic marks the target amplitude (specification).


1-33

FAST Bal I FAST Bal IIYou should now view the calculated trim correction. This step is required to complete a check run and also initiates data being assigned to the balance job.

If trim weights are to be used, add them without removing the initial bal-ance correction weights.

Job Completed:All steps have been performed. If trim weights were added, an additional check should be made.



NotepadThe notepad allows notes to be attached to the balance job for later recall or printing. The process is the same for Fast Bal I and II. Press the NOTES key to access the Balance Notepad. Pre-defined notes are available from four categories, or user defined notes may be created by selecting USER DEFINED.

10

Once a category has been selected, highlight the number of the desired note and press Enter to attach it to the balance job. When attached to a job, the entire note becomes highlighted.

11

Press Reset to return to the Balance Function menu. Notice the lower left corner shows one note has been assigned to this balance job.
