Load cell replacement
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 SITRANS WW310 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.
8.7.1
Removing old load cell
Step 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.
Step 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 feeder so it is hanging free
from the load cell.
