Introduction
2.0 Portable Installation
The MS200 Monorail Scale is for portable use and is
designed to bolt onto a straight section of either
3
/8" x
2 1/2" or 1/2" x 2 1/2" rail. The overall length of straight rail
required for the scale and ramps is 41". The scale body
requires a 22" space between existing support hangers.
The MS202 Monorail Scale is for permanent use and
comes with 52" of either
3
/8" or 1/2" rail. To install,
remove a straight section of rail, then cut the MS202 rail
to replace the section removed. Note: You can remove
a section as short as 14". Because the usual hanger
spacing of many existing mechanical scales is 48", most
often installers remove a 48" section of rail, and cut 48"
of the MS202 rail to fit between the existing hangers. We
recommend placing a new hanger near the scale to
reduce flexing and twisting within the 48" span.
On both models, the live section of scale is 8" long with
a slight concave dip so a trolley wheel will settle into the
dip. Only one trolley at a time will fit on the 8" live
portion of the scale.
1.0 Pre-Installation Checks
Before installing the portable monorail scale, check the
trolleys used in the plant to ensure there is adequate
clearance between the top of the swivel hook and the
bottom of the scale. See Figure 1. Check with the plant
operator to make sure all trolleys in use meet these
requirements.

1. Select a location for installation with at least 41"
of straight rail section. Avoid locating the
approach ends of the scale close to bends or
corners of the rail system. If the rail hangers
have less than 22" of space between them, move
one of the hangers to acheive the 41" clearance.

2. To begin installation, loosen, but do not remove,
the four top bolts (Figure 3, A, top of next page)
of the scale bracket. Remove the four lower
bolts (Figure 3, B, top of next page) of the scale
bracket. Slide the scale unit over the rail with the
load cell bracket toward the rail-hanger side of
the rail. At this point, move the scale left or right
along the rail to the desired location.
3. The installation kit provides two 1/16" shims,
2-1/2" x 20" long for use with portable monorail
scales on rails that are 3/8" thick. If the rail you
are using is 3/8", place one shim on each side of
the rail. If using a rail which is 1/2" thick, you do
not need the shims and may discard them.
4. Replace the four lower bolts when scale is in the
desired position. Before tightening all eight bolts,
be sure the scale body is contacting the rail
evenly along the entire length of the scale.
5. After tightening the bolts, check the alignment
of the ends of the approach ramps with the rail.
If the rail is not straight and true, correct the
alignment by loosening the bolts and inserting
pieces of shim stock between the rail and the
bracket. Do this on a "cut-and-try" basis until the
alignment looks smooth. When satisfied, tighten
all eight bolts.

6. Route the 25' load cell cable to the desired
location for the digital weight indicator. Do not
cut the cable, as the load cell is temperaturecompensated for exactly 25' of cable. It is
recommended that the cable be attached to the
rail assembly to prevent the possibility of damage.
See Figure 4.
Load Cell Cable to Indicator
Figure 4: Suggested Load Cell Cable Attachment
7. Rail hangers and their beam supports usually
provide a good place for attaching cable ties and
cable clamps. When attaching cable clamps, be
careful not to pierce the load cell cable.
8. Attach load cell cable to indicator.
1. Check that all trolleys using the scale have
adequate clearance to fit on the scale. See Figure
1 for minimum clearance size.
2. Remove an existing section of straight rail, then
cut the MS202 rail to fit the removed section.
Note: You can remove as little as 14" or, as
much as 52". To prevent having to weld in the
new rail section, choose a section supported
with hangers on each end. Bolt the new section
to the inner bolt holes of each hanger, as the joint
will lie at the hanger center lines. If the removed
rail section spans more than 24" between hangers,
install a new hanger close to the scale to prevent
rail twist when the installation is complete.
Add new support hanger
if distance between the
existing hangers is more
than 24"

3. Select a convenient location for mounting the
indicator tilt stand within the 25' allowed by the
load cell cable. If your location requires a
location further than 25', consult an authorized
Rice Lake Weighing Systems scale technician.
4. Before cutting and removing the planned section
of rail, be certain that the MS202 rail section is
3
the correct width (
/8" or 1/2"). Remove the rail
section, and cut the MS202 rail to the size of the
section removed.
5. Temporarily position the MS202 section in place
to match the alignment of the existing rail. Mark
the MS202 rail for drilling bolt holes matching
the inner holes of the rail hangers. Remove the
MS202 rail and drill a hole in each rail end for
the hanger bolts.
6. Bolt the MS202 rail section and scale to the
supporting hangers, shimming where necessary
to achieve good track alignment.
7. After properly routing and securing the load cell
cable and positioning the indicator, connect the
load cell cable to the indicator.
8. After you have made all cable connections, plug
the power cord into a 110V grounded outlet.
After power-up and lamp test, the display is
ready for weighing.

If your state requires a "place in service" report
for new equipment, a Rice Lake Weighing
Systems certified scale service company should
be contacted for assistance.
Both the MS200 and the MS202 are USDA approved for
use in federally inspected meat processing plants. In
addition, both models are NTEP type certified when
used with any NTEP-certified weight indicator.
