Load Cell Mount Installation 7
3.0 Load Cell Mount Installation
Load cell mounts, complete with load cells and conduit adapters, have been assembled at the factory to save on-site
installation time. Load cell mount installation consists of sliding the complete unit into place beneath the deck,
raising the mount with the leveling screws to the deck, and connecting the grounding strap.
When installing load cell mounts, start at one corner of the module assembly and install the remaining load cell
mounts on that side. Likewise, when the load cell mounts are installed on the other side, start with the corner of the
module assembly.
The lower mounts assemblies come complete with load cells installed, so complete any necessary welding on the
scale before installing mounts.
Remove load cell mount from packing box and file printed load cell Certification of Conformance (CC) in a safe
place for future reference.
3.1 Attach Upper Mount Chair
1. Attach the upper chair to the bottom of the module assembly by using four 3/4" bolts with washers making
sure that the 1/4" hole for ground strap installation is toward the center of the scale module.

2. Torque upper chair bolts to 200 ft-lb.
3.2 Prepare Baseplate and Mount Installation
1. Turn the four leveling screws through the baseplate so approximately 1/2" extends beyond the bottom
surface.
2. Each load cell mount comes equipped with a 90 degree threaded LB conduit adapter. Orient the adapter so
that the cable will point toward the inside of the scale when mounted.
Each mount must be oriented so the cable exit from the load cell is facing the interior of the module to which
it will be attached. The correct orientation will place the flexible conduit section on the load cell near the rigid
conduit attached to the weighbridge.
3. If a load cell must be reversed to achieve correct orientation, remove a load cell and reverse its direction in
the field. When re-tightening load cell bolts, torque to 70 to 80 ft-lb. The 90 degree fitting on the flexible
conduit attached to a load cell can rotate 180 degrees to allow for correct conduit placement.
4. Set the mount assembly on the concrete pier directly in front of its final position. Carefully slide the mount
into position under the upper chair.
