GENERAL
This scale system must be installed on a firm and level surface. Particular attention should be paid to the load
bearing points at the end of each module. Note that if the area between the ends of the scale is too high it will
cause weight errors by rocking the sub-frame. The same condition can be created if surface settling occurs, the
center of the frame will not compress the surface at the same rate as the load bearing ends. This will create the
same bind as the unleveled surface described above.
INSTALLATION STEPS
1. Site preparation. You should have a firm and level surface area that is at least one (1) foot wider and five
(5) feet longer than the overall dimensions of the scale. For a temporary installation compressed stone is
adequate. For any installation over 6 months it is recommended that concrete footers be poured below frost
level.
2. Determine where your indicator will be installed and arrange the scale so the J-Box is located on the
same side. Note that the J-Box is located under the access plate on one side of the deck plate. In the center of
the length.
3. Set the first module. Lifting points are provided on the four corners of the scale frame.

4. If dead spaces are to be used these need to be placed as needed. They are designed for either stone
fill for temporary use or to be filled with concrete for more permanent use. If filled with concrete a
rebar pattern of 12” square of ½” rebar is recommended. If you plan on moving them after concrete
is poured a heavy visqueen should be placed below them so they do not adhere to the surface. They
also have lifting rings on the four corners if you would like to move them in the future.
5. After all modules and dead spaces are in place the scales can be ramped up to with stone or optional
ramps can be installed.

6. Open up the access covers over the load cells. All four corners of the platform and remove the tie
down bolts. It is recommended that the tie down bar be laid across the beams of the scale
weighbridge. We also recommend that the bolt be placed back into the threaded hole to avoid dirt
accumulation.
7. If scale system is installed on a concrete foundation anchors should be installed through the provided
anchor holes. One at each load cell access hole. Using a ¾” x 4” concrete anchor.
8. Make sure there is load on all load cells of the scale. No rocking from corner to corner. If there is
rocking shim under the scale frame.

9. The load cell assembly is designed to rock in place. The cell should be seated in the upper and lower
receiver plates.
10. Wiring the load cell are all wired into the junction box located under the access plate in the center of
one side of the platform.

11. If more than one platform is to be wired into an indicator. An option board will be supplied similar
to below.
You will need to wire the platforms into this board for adjustment from platform to platform
The + Signals from all platforms will all wire into + Sig on the left
The - Signals from all platforms will all wire into – Sig on the left
The - Excitation from all platforms will all wire into - Exc on the left
The individual +Excitations will wire into + Exc 1-5 depending on the number of
platforms used. The indicator cable will wire into the connector on the right.
The potentiometers will be used to adjust the scale platforms to each other. Just like
adjusting individual sections of a truck scale.
