ROTALIGN 01.2000
Horizontal machine alignment - laser beam adjustment
The two detectors can be seen in this display. The beam should
be centered in both planes which may require using the thumb-
wheels. It some cases it may be necessary to move the receiver
and/or laser along their posts or the bracket may have to be
loosened and slightly rotated. Retighten the components when
finished and press ESC.
If there are measurements available for the current machine,
the CURVE FIT softkey appears for displaying the YY ellipse (see
page 4-45 for a complete description of the CURVE FIT option).
TRACE
In TRACE mode, entered by pressing the TRACE softkey in the XY
View screen, a line representing the laser beam is traced between the
two sensors. Although it cannot be used while taking actual measure-
ments, this mode provides quick insight into angularity and offset
conditions and is also of use while aligning the laser and receiver.
If, while rotating the shafts, the traces on the left (front) sensor

remain in the same position and the traces on the right (rear) sensor
change, suspect angularity. On the other hand, if the traces move
equal amounts on both sensors, offset is most likely the culprit. To
exit trace mode, either press ESC softkey or select the TRACE softkey
again.
When you have completed measuring, return to the menu and select
another option or press the
(results) key.
