ROTALIGN 01.2000
Horizontal machine alignment - measurement
MULTIPOINT (5 at least)
In this measurement mode for horizontal machines only, you rotate
the shaft to any desired angles and press TAKE POINT. This is
recommended when you have very restricted shaft rotation or if you
want to have more control over the measuring points than with the
"Continuous Sweep" mode. This may be the case with turbines.
You can select and deactivate "rogue" points with the arrow softkey
and "–" softkey (see page 4-41 for details).
Note: measurement at each position begins when the key is
pressed. Therefore, please wait 2 seconds after pressing the TAKE
POINT key before you begin to rotate the shafts to the next
position.
PASS MODE (UNCOUPLED)
This mode is used when either:
1. The shafts are uncoupled, or
2. One or both of shafts cannot be rotated.
Proceed as follows:
1. If the shafts are rotatable but uncoupled, mount the laser and
receiver on chain brackets in the normal way:
2. If a shaft cannot be rotated, the ALI 2.230 magnetic sliding
bracket must be used (see Appendix, page 6-18):
Mount the sliding bracket on the coupling flange or exposed end
of the nonrotatable shaft. The flange or shaft must be steel,
surface-finished, clean and lightly oiled. Alignment accuracy
depends on these conditions! Aligning two nonrotatable shafts
both with sliding brackets is possible but very dependent on the
surface finishes and should be regarded as a method of last
resort.
