value mode. The following options are available:
● Bolt correction (+): means all shimming corrections are positive (add shims)
● Bolt correction (-): means all shimming corrections are negative (remove
shims)
● Bolt correction (+): means all shimming corrections are minimized (optimized).
Therefore half of the corrections will be negative and half of them positive.
This option results in zero axial movement of the shaft.
Machine alignment
Alignment is carried out by correcting angularity and offset at the flange.
Correcting angularity
1. Loosen the flange bolts and lift the upper machine.
The machine bolts must be undamaged and removable.
2. Angularity corrections are made by shimming. The "Bolt corrections" screen
shows the shimming values at the respective bolt locations. Insert (or remove)
shims with the correct thickness under the selected bolt.
3. Retighten the bolts and then re-measure to verify flange shimming results and
determine the exact alignment condition.
Correcting offset
The correction of offset misalignment is carried out using the Live Move function.
1. Access the "Main menu" screen by pressing
and highlight the 'Move' icon.
