Welding

WARNING:
the belt scale. Ensure that no welding current can flow through the belt scale.
Welding currents passing through the scale can functionally damage the load
cells.

Load Cell Handling

The MLC belt scale is designed for low-capacity operation and is constructed using two
10 or 20 pound load cells. Although the load cells are protected by shipping stops that
keep the cells from moving, care should be taken when handling the scale to avoid
damaging the cells. The stops are metal strips about 75 mm (3") long with holes at each
end for screws. One screw holds the stop to the load cell while the other screw holds the
stop to the static beam (125 mm [5"] channel).
When handling the MLC during installation and set-up, make sure the stops remain in
place.
Reinstall both shipping stops during maintenance or prolonged shutdown.

Installation Precautions

The following precautions should be observed when handling the scale.
• Do not pry on the idler, its mountings, or the cells directly.
• Do not stand or lean on the scale.
• Avoid shock from blows of a hammer when trying to position the scale during
installation.
• Do not lift the MLC by its idler.
• Do not lift the MLC by the idler mounting brackets.
