Quick startup overview
1. Verify that the weighfeeder is installed properly as described in Installing (Page 11). Verify
that the belt is tracking and the shear gate (if used) is properly set.
2. Verify that the weighfeeder, integrator/controller, and variable speed drive (AC or DC, if
present) are all properly wired.
3. Refer to the supplied integrator/controller information for calibration and configuration
information.

Load cell replacement
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.
If a load cell on the weighfeeder has been damaged and is not functioning, or if you are
changing the capacity, you will need to replace one or all load cells.
Note
Please read and understand all of the instructions before proceeding with the replacement.
Contact your Siemens representative for assistance if you have any questions or problems.
7.9.1
Removing old load cell
1. Confirm the new replacement load cell is correct and functional. Using a digital volt meter or
ohm meter, verify that the resistance of the new load cell matches the resistance printed on
the specification sheet that comes with the load cell. If the resistances do not match, the load
cell may be damaged. Consult your Siemens representative.
2. Disconnect the load cell being replaced from the junction box. Verify that the load cell is
connected according to the interwiring diagram supplied with this manual. Disconnect the
load cell from the load cell junction box. Free the load cell cable from the weighfeeder so it
is hanging free from the load cell.
3. Support the scale deck from below or above, and remove the two top/front load cell
mounting bolts. Be careful not to move the deck as it is still attached to the load cell on the
other side of the weighfeeder.
4. Remove the two bottom load cell mounting bolts.
5. Remove the load cell off the weighfeeder.
