The screen then displays the movement required to align the machine
horizontally. The bull’s-eye target indicates how well the machine is
aligned with respect to tolerances.
Horizontal live moveFigure 4-6:
Perform the live move with the laser fixtures at any rotational position.
Before proceeding, make sure that the laser fixtures are located at a
position where they can remain stable throughout the alignment
process. The average laser and sensor angle position is displayed in the
middle of the screen. The background of the box is green when the laser
fixtures are within 2° of each other, and is white if the laser fixtures are not
within 2° of each other.
For horizontal machine moves, if the required movement is positive, the
amount of movement is shown below the machine at the appropriate
foot with a down arrow. If the required movement is negative, the
amount of movement is shown above the machine at the appropriate
foot with an up arrow.
The bottom half of the AMS 2140 screen shows a bull’s-eye target and a
shaft centerline plot representing the alignment condition of the
machine. The shaft centerline plot includes a “V” shape indicating the
acceptable angular tolerance on the machine as well as a bracket at the
base of the “V” showing the acceptable offset misalignment at the
coupling.
