Installation
The MMI is shipped from the factory as a single unit attached to a shipping frame for
protection. Each MSI weighbridge must be removed from its shipping frame and
inspected for physical damage.
Be sure the conveyor design meets the installation requirements for the Milltronics MMI
belt scale. The conveyor stringers must be rigid, straight, parallel to and square with the
belt line in the area of the scale installation. The idler to be used on the scale and at least
the next two approach and retreat idlers must be of the same style and manufacture and
in good condition.
Prepare the site in accordance with the Siemens Milltronics drawing(s) provided or by
referring to the Belt Scale Applications Guidelines (7ML19985GA01).
Welding
WARNING:
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 load cell can tolerate very little negative displacement without damaging the load
cell.
When handling the individual MSIs, install both shipping stops to their vertical position to
protect the load cells. Do not lift the MSI by the dynamic frame or subject it to shock from
blows of a hammer when trying to position it.
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.
•
Overloading, shock, and twisting of the scal can damage the load cells.
•
Do not lift the MMI by its idler.
