Early alignment methods involved using a straightedge along the coupling rims.
This is still a good procedure to use as a preliminary step. In fact, for low speed
machines, operated infrequently for short periods of time, it may be all that is
needed.
However, more complex machines require more than this. Feeler gages, inside
micrometers, and dial indicators are now used extensively for taking precise align-
ment measurements and monitoring corrective moves. These tools can give good
results when used properly.
Mistakes, however, can cause errors in the alignment procedure. Errors that com-
monly occur are:
• Failing to document the job setup, problems, findings, and data
• Failing to use good indicator brackets
• Failing to determine the correct amount of bracket sag
• Misreading the indicators
• Failing to detect sticking indicators
• Mistakes in recording and interpreting the data
• Errors in calculating the moves
• Errors in making moves
These types of errors are even more likely to occur when you have pressure to com-
plete the job quickly.
The Emerson CSI alignment equipment can help you avoid these kinds of mis-
takes. Our adjustable brackets are designed to fit most machines. Since there are no
axial projecting arms, bracket sag is zero. Misalignment readings are calculated
automatically and required moves are then displayed. If a serious mistake is made,
the system will prompt you for corrected entries before moving on to the next step.
Completed jobs are easily documented. Documented jobs can then be stored in
UltraMgr, a PC-based, corrective technologies information management system.
This documented history can be used to enhance troubleshooting, identify per-
sonnel candidates for additional training, reduce alignment time, etc. See
“UltraMgr” on page 3-199 for more information.
