Load Cell Replacement
Use the following steps to replace load cells in the RoughDeck CS Rail Car Coil Scale.
Figure 5-1. Load Cell Mount
1. Position a jack on the concrete foundation beneath one of the weighbridge’s main frame members close to the load
cell mount, allowing room for load cell removal and installation.
2. Raise the jack approximately 1/2" and put setting block(s) under the scale deck.
As a safety precaution, always use setting blocks when jacking up a scale module.
3. Disconnect the load cell terminal connections in the junction box. Pull the load cell cable out of the conduit.
Attach a pull cord to the load cell cable at the junction box before pulling the cable through the conduit.
4. Remove the two load cell bolts and lift out the load cell and the link assembly.
5. Install link over the new load cell. Reinstall the load cell and link assembly onto the baseplate. Install load cell mount
bolts. Torque bolts to 55 ft-lb.
6. Pull the load cell cable through the conduit using a pull cord.
7. Remove the setting blocks and lower the scale module so that it rests on the link. Check the link to verify that it is
centered and plum.
8. Connect wiring to the terminals in the junction box.
