4/ Measure the alignment status
Rotate the shafts, to position the MU's, as indicated by the
blinking circle symbol on the display during each step (see fig 2).
Validate each measurement with
Fig. 2 Measuring positions
5/ Live results
Live alignment values are displayed on the DU.
Live vertical values are displayed when the MU's are in the
12 o'clock position.
Live horizontal values are displayed when the MU's are in the

While aligning, observe the live coupling values displayed on
the screen.
Coupling values must be within the maximum acceptable
misalignment value (see Annex 3), or within the tolerance given
by the original equipment manufacturer.
6/ Checking the soft foot
It is recommended to check the
movable machine for soft foot before
starting the alignment.
After operation 1 to 3 are performed,
position the MU's to the 12 o'clock
position.
Press + and - simultaneously to enter
the soft foot mode.
Press "next" to zero the feet values displayed.
To check a foot, loosen the foot bolt. Monitor the F1 value in
case of a front foot, the F2 value in case of a rear foot.
Register this value.
If the value is less than 0.05 mm (2 mils), the support is good.
Re-tighten the bolt and check another foot.
If the value is more than 0.05 mm (2 mils) this foot can be the
soft foot. Tighten back the bolt and check the diagonally opposite
foot. The soft foot is the one with the largest deviation.
When all feet are checked, correct the soft foot, if any.
