Introduction

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.

A section as short as 14” can be removed. 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.

It is recommended to place 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.

Use only high strength L9 (Grade 9) bolts and flat washers to attach load cells to the scale frame. Use only 140,000 PSI or greater fasteners on rail attachment points. Failure to follow this warning can cause severe injury or death.

Installation

This section provides an overview of MS200 and MS202 Monorail Scale installation information.

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 (Figure 2-1).

Portable Installation

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 achieve the 41” clearance.

2. Loosen the four top bolts (Figure 2-3 on page 3) of the scale bracket.

3. Remove the four lower bolts (Figure 2-3 on page 3) of the scale bracket.

4. Slide the scale unit over the rail with the load cell bracket toward the rail-hanger side of the rail then move the scale left or right along the rail to the desired location.

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.

5. If the rail is 3/8”, place one shim on each side of the rail. If using a rail which is 1/2” thick, shims are not required.

6. Once in position, replace the four lower bolts.

7. Ensure the scale body is contacting the rail evenly along the entire length of the scale.

8. Tighten all eight bolts.

9. 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 then tighten all eight bolts.

10. 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 temperature compensated for exactly 25′ of cable. It is recommended that the cable be attached to the rail assembly to prevent the possibility of damage (Figure 2-4).

11. 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.

12. Attach load cell cable to indicator.

Permanent Installation

1. Check that all trolleys using the scale have adequate clearance to fit on the scale. See Figure 2-1 on page 2 for minimum clearance size.

2. Remove an existing section of straight rail then cut the MS202 rail to fit the removed section.

The existing section of straight rail that should be removed should be in the range of 14” – 52”. To prevent having to weld in the new rail section, choose a section supported with hangers on each end.

3. 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.

4. Select a convenient location for mounting the indicator tilt stand within the 25′ allowed by the load cell cable.

If the location requires a location further than 25′, consult an authorized Rice Lake Weighing Systems scale technician.

5. Ensure the MS202 rail section is the correct width (3/8” or 1/2”) then remove the rail section, and cut the MS202 rail to the size of the section removed.

6. Temporarily position the MS202 section in place to match the alignment of the existing rail.

7. Mark the MS202 rail for drilling bolt holes matching the inner holes of the rail hangers.

8. Remove the MS202 rail and drill a hole in each rail end for the hanger bolts.

9. Bolt the MS202 rail section and scale to the supporting hangers, shimming as necessary to achieve good track alignment.

10. Route and secure the load cell cable and positioning the indicator.

11. Connect the load cell cable to the indicator.

12. Plug the power cord into a grounded outlet.

13. Power on the device. The display is ready for weighing.

If a place in service report is required for new equipment, contact a Rice Lake Weighing Systems certified scale service company for assistance.
