Start Up
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 DC motors, reverse the armature wires. 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
Belt Tracking
correctly, see
Shear Gate
The shear gate on the inlet of the weighfeeder needs to be set to allow the maximum
feedrate capacity for the application, hieght is provided in the outline drawings included.
Consult your Siemens representative if feed rate changes are required.
Skirtboards
The skirtboards have been factory set. Note that near the inlet, the skirtboards are very
close to the belt. However, the distance between the skirtboards is greater at the
discharge end: the skirtboards are 1/8 to 3/16" off the belt. This tapering improves material
flow and will help the product move down the belt without "bottlenecking."
Adjustments of the skirtboards should not be necessary but if they are required, set the
skirtboards at the heights described above.
Changing the Conveyor Belt
WARNING: ALWAYS STOP the belt, lock-out, and/or place a "Do
Not Energize" tag on the main disconnect before working on or
around the weighfeeder.
1.
Open and remove the access and non-access side covers (omit this step on open
construction models).
2.
Mark the position of the telescopers for reference. This will be handy when you re-
install the belt. Loosen the telescopers to remove tension from the belt.
