4-174 l Operation
Setting the Scale Factor
The Encoder Mode uses a scale factor to compensate for configurations that differ
from the standard (a measuring wheel with a 1 foot circumference; a 3000 pulse
encoder; and English units of measure). The prescale value is set at the factory for
your equipment and typical unit of measurement. However, it may occasionally be
necessary to adjust the prescale value.
Checking Cut Quality
1 Press the “Manual Cut” button and observe the movement of the cutter
blade. The cutter head makes a single rotation and the blade moves through the
cutter bushings without interference.
2 Insert a piece of extrudate through the cutter bushings.
3 Press the “Manual Cut” button. A single cut is made at the preset blade
speed.
4 Inspect the cut. If necessary, adjust the blade design or blade speed.
See Appendix B: All About Cutter Blades.
When you are satisfied with cut quality, press the Cut On/Off SoftKey and ON is
displayed, automatic operation begins.
When the extrudate is running within tolerance, cut it with a knife or saw and feed
it through the cutter bushings. Then move the cutter into position with respect to
the puller:
• For flexible products, the cutter should be very close to the puller.
• For more rigid products, allow enough space between the cutter and puller
to absorb any shock generated during cutting.
NOTE: this works even if Cut On/Off is off.
