Your weighfeeder has been factory run-in for a minimum of four hours; it should require little
adjustment. However, periodic inspections of the belt tracking are recommended.
Start the belt and observe rotation.
WARNING
Turn off and lock out all power sources before correcting rotation. On AC motors, reverse 2
of the 3 motor wires.
Start the belt again, and observe the machine as it is running. If the belt is not tracking correctly,
or is travelling off center, see Belt tracking (Page 21).
7.1 Shear gate
The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum feed rate
capacity required. Consult your Siemens representative if feed rate changes are required.
7.2 Skirtboards
The skirtboards have been factory set to proper specifications. Note that near the inlet, the
skirtboards are very close to the belt. However, toward the discharge end of the weighfeeder,
the skirtboards are 3 to 5 mm (1/8 to 3/16") higher off the belt. This relieving effect minimizes the
possibility of material becoming lodged between the skirtboard and the belt.
Periodic adjustments of the skirtboards should not be necessary but if adjustment is required,
set the skirtboards at the heights described above.
