PF Loop Scale Assembly Affixing Procedure
When assembling the PF loop scale unit, the following exclusive tool should be
used.
n Exclusive tool No. #F731 : PF Loop Scale Affixing tool
The assembly procedure is given below.
1. Set the PF loop scale assembly's double sided tape side on the grid roller
side, align the internal diameter of the PF loop scale with the left end of the
grid roller (PF roller) and set it lightly.
At this point, the PF loop scale assembly should not
•
be fitted on the grid roller as far as it can go. If the PF
loop scale assembly is placed on the grid roller by
hand, it could damage the PF loop scale assembly's
internal diameter and the distance from the center of
the grid roller to the scale reading part would not be
the same all around any more, resulting in a drop in
the encoder sensor's reading accuracy.
