5-20 Using UltraSpec Alignment - General Overview
Thermal Growth, Vertical
Thermal Growth (Vertical) Screen
This screen shows a side view of the coupled machinery. The amount of
vertical thermal growth that both machines will experience during opera-
tion can be expressed in either mils or millimeters (mm). Thermal growth
values should correspond to the amount each shaft will move in the vertical
direction directly above each foot. If thermal growth is negligible, enter
zeroes. The range of values that can be entered are -250 to 250 mils and
-6.35 to 6.35 mm.
Press the Up Arrow or Down Arrow to toggle between the growth values.
If one or both machines actually experience a downward growth during
operation, negative numbers should be used. Press the Enter key to accept
the vertical readings; then, the Thermal Growth Horizontal screen will
appear.
Note
The Thermal Growth screens only appear in the Job Definition
section if Thermal Growth is set to Yes in the Options, Align-
ment Setup menu. Refer to “Alignment Setup” on page 3-6 for
more information.
