Milltronics MMI Belt Scale
Milltronics MMI belt scale is a heavy-duty, high-accuracy multiple idler scale for critical
process and load-out control. The MMI uses two Milltronics MSI belt scales in
succession. The scales are designed to be inserted into belt conveyors for continuous
weighing of dry bulk solids.
Each MSI includes:
• one weighbridge c/w two load cells with leads run in liquid-tite conduit and 150 cm
(5 ft.) of interconnecting cable terminated with lugs and conduit fitting
• Siemens Milltronics test weight(s)
The addition of an idler (supplied and installed by the customer) to each weighbridge
completes the weighing assembly. The MMI load cells provide an electronic signal,
proportional to load, which is fed to the integrator. Thus, weighing is accomplished
without interrupting the process and without affecting the process material. The MMI is
used where conveyor belt speeds or belt loading charactistics result in conditions that
necessitate extending the weighing time beyond the capibilities of a single idler scale. It
is also well suited for applications that require higher sustained accuracies, such as
production control inventory accountability or where certification for trade purposes is
required.
The MMI is an accurate and repeatable force sensor. Its performance is ultimately
dependent upon the conveyor system and the quality of the installation and alignment.
Safety Notes
Special attention must be paid to warnings and notes highlighted from the rest of the text
by grey boxes.
WARNING means that failure to observe the necessary precautions
can result in death, serious injury, and/or considerable material
damage.
Note: means important information about the product or that part of the operating
manual.
The Manual
This instruction manual covers the installation, operation and maintenance of the MMI
belt scale. Because the MSI belt scale is used in conjunction with an integrator and
optional speed sensor, the instruction manual covering these components must be read
as well.
Please refer to this manual for proper installation and operation of any component of the
weighing system including the MMI. Adhering to the installation and operating
procedures will ensure a quick, trouble-free installation and allow for the maximum
accuracy and reliability of your weighing system.

Operation
Each MSI weighbridge is designed to react only to the vertical component of the force
being applied to it. Each MSI consists essentially of a fixed support frame (static) and a
live frame (dynamic).
The static assembly is used to mount each MSI between the conveyor stringers and
supports the weighing assembly via its load cells.
The weighing assembly supports the scale idler and transfers the weight of the material
to the load cells. These are the active components in the weighing assembly.
As the material travels along the conveyor belt, a force is exerted through the suspended
idler onto the weighing assembly. The weighing assembly is forced down proportionally.
The movement in each load cell is sensed by its strain gauges when excited by voltage
from the electronic integrator and produces a signal proportional to weight, which is
returned to the integrator. The movement in each load cell is limited by the positive stop
incorporated in the design of the load cell.

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:: Use extreme care when arc welding in the area of 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 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.

6. The idlers in the weighing area must be properly aligned and leveled by shimming
the scale idler (S#), the two approach (A#) and the two retreat idlers (R#) until they
are within ± 0.8 mm (1/32") of each other. Be sure to check that the idlers are
centered and squared to the conveyor during the shimming process.

7. Precise idler alignment is very important if maximum accuracy of the weighing
system is to be achieved. Misaligned idlers will result in unwanted forces being
applied on each idler in the weighing area, causing calibration and measurement
errors. Use a good quality wire or string to check for alignment. The wire or string
must be able to withstand sufficient tension in order to eliminate any sag. Adjust
shims so that all rolls of the A2 through to the R2 idlers are in line within 0.8 mm
(1/32").

Although the accepted tolerance for idler alignment is ± 0.8 mm (1/32"), the scale
mounted idler should never be lower than the adjacent idlers. Establishing good
idler alignment is the most important part of the installation procedure. Scale
accuracy is directly affected by alignment.

Page 15
Calibration
After the MSI has been properly installed, calibration of the weighing system must be
done in conjunction with the integrator. Refer to the integrator instruction manual for
programming and calibration. The calibration is initially done using the supplied test load.
Material tests are recommended to achieve maximum accuracy.
Tes t Load
The test load value for your MSI is given on the accompanying data sheet. The value is to
be entered into the dedicated programming parameter of the integrator, in kilograms per
meter or pounds per foot. An equal number and mass of weights must be applied to each
suspension during the span calibration function.
If the actual idler spacing differs from that recorded on the design data sheet, the test
load must be recalculated as follows. Failure to do so will cause the design test load
value to be in error.
test load = Total weight of all test weights
idler spacing m ft
The above calculation must be performed for each MSI scale suspension using the
weights designated for that particular suspension.
Enter the average value of the two calculations into the integrator’s Test Load Parameter
(test load value “A” + test load value “B”)/2 in kilograms per meter or pounds per foot.
Kg or lb
)
(

(
Zero
Perform the zero calibration as described in the Calibration section of the integrator
manual.
Span
The test load used in the calibration procedure is the two sets of test weights ( 1 to 12 )
supplied, one for each MSI suspension.
Place each set of the test weights onto the calibration weight bar of the respective MSI
as shown. Perform the span calibration as described in the Calibration section of the
integrator instruction manual.
After the span calibration has been completed, remove the test load and store it.

Material Test
The MMI is guaranteed to be accurate to ± 0.25% when installed on a conveyor in
accordance with this manual and meeting the qualifications outlined in the Belt Scale
Applications Guidelines (7ML19985GA01). This guarantee is based on calibrations
performed using the test weights furnished with the scale and as referenced on the
previous page.
When the existing conditions are such that the installation of the scale cannot meet the
above mentioned requirements for an approved installation it is recommended that
Material tests be performed. This will enable the user to compare the present scale
results to the results of the material tests. The scale is then adjusted or factored so that
subsequent scale calibrations with test weights will agree with actual run of material.
Re-Rating
To be sure that proper design parameters are maintained, consult your Siemens
Milltronics representative for any significant change in rate, speed and /or idler spacing
from original design specifications.
Page 12 Milltronics MMI Belt Scale – INSTRUCTION MANUAL 7ML19985DR02
Page 17
Maintenance
Keep each weighbridge clean. Accumulation of material between the fixed support
frame (static) and the live frame (dynamic) as well as around each load cell could affect
the scale accuracy.
Periodically check the alignment of the stringers and idlers in the weighing area.
When a problem arises in the conveyor, it is possible that the scale will be affected.
Therefore, periodic conveyor maintenance is important to proper scale operation which
should include:
• lubrication of all pulleys and idlers
• proper belt tracking and training
• proper belt cleaning and scraping
• proper take up operation
• proper material feeding and spillage
•control.
You can observe the integrity of the load cells by performing zero and span calibrations. If
the zero and span deviations display a continuous unidirectional drift or the system
becomes uncalibratable for no apparent mechanical reason, the load cells may be
suspect.
Spare Parts
The only spare part recommended for the MSI is the load cell. Refer to the load cell
nameplate for the proper size and model number.
Re-balance any load cell that has been replaced. Refer to the Load Cell Balancing
Procedure For Four Load Cells in the integrator manual.
Maintenance Precautions
• When welding near the scale, do not allow current to pass through the belt scale.
• Reset the shipping stops to reduce physical shock to the load cells during
maintenance.
• Recalibrate the scale after maintenance and prior to use.
