7.9 Load cell replacement
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 idler from below or above, and remove the two top/front load cell mounting
bolts. Be careful not to move the idler 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.
