The bull's-eye target compares the total misalignment to the target tolerance. Each
circle in the bull's-eye target has a different meaning: red—more than two times the
tolerance, yellow—between one and two times the tolerance, green—within
acceptable tolerance, green with a star—within excellent tolerance.
2.
Press F2 Start to start the live move.
a. Press F5 Alternate Move to select between the alternate pairs of feet.
b. For Dual Move (horizontal and vertical), press F9 Show Center Lines to view the
alignment condition with respect to the machine center lines, or press F9 Show
Machine to view the alignment condition with respect to the machine
components defined for the job.
3. Loosen the machine feet hold-down bolts, and then move the machine until the
target tolerance level is reached.
As the machine is moved, the bottom half of the analyzer screen provides a
continuous update of the machine alignment condition.
When the live move alert is enabled, the status LED on the analyzer flashes and an
audible alert is heard (only when the Status Beeper is set to on) when the target
tolerance value is reached during a live move. See Section 7.4.5 to enable live move
alerts.
4. Tighten the machine hold-down bolts when you reach the target alignment
condition.
5. Press F2 Stop to stop the live move.
6. Acquire alignment data again to verify the machine alignment condition.
CAUTION!
A live machine move is not a reliable indicator of the final alignment condition of a
machine. There will be variability in the alignment data due to shaft clearances, bearing
faults, base deterioration, etc. Emerson recommends acquiring a new set of alignment
data after performing a live move.
7.5.11 QuickSpec
QuickSpec is available only for Advanced horizontal alignment jobs.
QuickSpec mode allows you to check the alignment condition of a machine with minimal
setup and effort. If a machine has unacceptable alignment, the procedure can be readily
converted to a full alignment procedure and machine moves calculated.
QuickSpec launches when you only enter the RPM and the E dimensions. See Section 7.5.1
for more information on entering machine dimensions.
When the QuickSpec mode is activated, the thermal growth and review results options are
disabled.
In this mode, only the tolerance plot information is available since the machine move
information cannot be calculated without the complete machine dimensions.
