Installation
Notes:
• Installation shall be performed only by qualified personnel in accordance with
local governing regulations.
• Use only approved conduit and conduit fittings or cable glands to maintain NEMA
or IP rating, as applicable.
• For hazardous area installations, use only approved junction boxes, metal conduit
and conduit fittings or cable glands. Adapter supplied for ½" NPT to M20x1.5.
Discard if using ½" NPT conduit fitting.
• Adjust conveyor stringers to be rigid, straight, parallel to, and square with the belt
line in the area of the scale installation.
• Adjust pulleys to ensure that the conveyor belt tracks straight and centrally from
the head to the tail pulley.
The MCS is shipped from the factory as a single unit attached to a shipping frame for
protection. Each MCS 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 MCS
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) or by referring to
the Belt Scale Applications Guidelines (7ML19985GA01).
Welding
WARNING:
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 MCS, install both shipping stops to their vertical position to protect
the load cells. Do not lift the MCS by the dynamic frame or subject it to shock from blows
of a hammer when trying to position it.
