Introduction
OPERATIONS
Chapter 1 - Introduction
OPERATIONS
The LoadMan® LM400 Touch is a precision computer capable of
running and controlling many different vehicle weight measurement
applications. The application documented in this manual is
programmed for front load, fork based vehicles that weigh commercial
containers in motion as they are picked up, dumped, and lowered to
the ground.
The LoadMan system is completely automatic and no action is needed
on the part of the driver to obtain a weight reading. The LM400 Touch
screen provides all the information a driver needs to understand the
status of the weighing system.
The container load weights are measured and reported to the driver as
a net load weight. The dumped load weights are accumulated with the
weight of the existing material in the vehicle, providing the driver with a
running total of the net vehicle weight or the gross vehicle weight.
LoadMan not only supports in-motion weighing of the contents dumped
into the truck, but also records optional route, account, and GPS data
along with the measured load data.
Figure 1 LM400 Touch Operations Screen
NOTE By default, the LM400 Touch displays weight
measurements in English units (LB), and this guide uses English
units in all examples. However, the LM400 Touch can also be
configured to display weight in metric units (kilograms, tonnes).

Introduction
The LoadMan System
OPERATIONS
The LoadMan LM400 Touch fork based weigh-in-motion system
consists of three digital electronic components:
• LM400 Touch Computer—An in-cab computer for displaying
weight, route and system information.
• Arm Box 300—A computer based arm box that is mounted in a
steel protective enclosure on the lift arm.
• Fork Box 300—A fork weigh-in-motion assembly mounted in a
steel protective enclosure on the fork assembly.
LM400 Touch
Fork Box 300
Arm Box 300
Figure 4 LoadMan LM400 Touch Weighing System
The fork box converts the sensitive analog signals from the two fork
loadcells to a digital number, using a precision digital to analog encoder
called a LoadCoder®. It also measures the fork angular position and
acceleration, converts the information to a digital number, and transmits
the data to the arm box.
Rev 11.2013-1
3
Introduction
The arm box also contains an angle sensor, which informs the system
of the angular position and acceleration of the lift arm at all times.
The arm box gathers the weight measurement from the two fork
loadcells, the fork angular position and acceleration, and the arm
position and acceleration. It then processes this information to
determine the weight of the containers plus its contents while going up.
Then, in the same manner, measures the tare weight of the container
going down. The difference between these two weights determines
the weight of the material that was dumped into the truck. All of this
information is transmitted to the in-cab LM400 Touch computer and
displayed to the driver.
The LoadMan Load Management Software (operating on an office
PC) allows remote tracking of trucks, drivers, customers, routes and
products by account or job. Route lists are created with the software
and downloaded to the LM400 Touch computer. Any recorded load
data and GPS position data in LoadMan’s data collection memory is
automatically transferred to the Load Management Software without
any prompting or intervention from the driver whenever a wireless
modem connection is established. For more information,
see “Appendix F - LoadMan Load Management Software.”
How to Use this Guide
This guide is organized into three sections to make it easier to find the
information you need:
• OPERATIONS is primarily designed for the driver. It contains basic
information about the LoadMan system and day-to-day operating
instructions.
• ADMINISTRATION is designed for the dealer or system
administrator. It includes instructions for calibrating a newly
installed LoadMan system and configuring system settings.
• TROUBLESHOOTING provides detailed instructions for the system
administrator or technician tasked with isolating and resolving
problems that may occur with the LoadMan system.

OPERATIONS
The LoadMan system is highly automated and requires minimal driver
intervention. This chapter provides an overview of normal LM400 Touch
operations and describes the tasks a driver may need to perform,
including how to:
Normal Operations
After the load data is recorded, the Operations screen may
automatically display account information for the next stop, depending
on how the system is set up:
• If the system configured to use the Geo-Route feature, the
stop location is detected by its GPS coordinates as the truck
approaches, and the Operations screen automatically displays the
appropriate account.
• If the system is configured to use the Auto-Increment feature, the
Operations screen automatically displays the next account in the
route sequence after the previous load is recorded.
• If the system does not have the Geo-Route or Auto-Increment
enabled, you will need to manually select the appropriate account
before picking up the next load.
If Geo-Route is enabled, LoadMan will list the location of all cans or
containers within a 500 foot radius of the truck. If no containers are
listed, you can expand the search to cover a larger area
(see page 19).
If the LM400 Touch is connected to an in-cab printer or a scoreboard
mounted on the truck exterior, the load data may automatically print
after the data is recorded, depending on how your system is set up.
You can also choose to manually print the previous load data (see page
21).
The LM400 Touch may come equipped with an onboard GPS with
Bluetooth wireless modem or GSM cellular modem. The modem
automatically connects and communicates with the LoadMan Load
Management Software and exchanges load data, location information,
and route information with the LM400 Touch. This occurs automatically,
and no action is required by the driver.

Initial Startup and Calibration
ADMINISTRATION
Chapter 4 - Initial Startup
and
Calibration
This chapter provides the dealer or system administrator with step-bystep instructions for verifying and calibrating a newly installed LoadMan
Fork Based Weigh-In-Motion system. After completing these steps, see
Chapter 5 to configure system settings.
Step 1: Verify the Wiring
Begin by verifying that the electronics are wired according to the wiring
diagram shown in “Appendix A - Wiring Diagram.”
1. Check that positive 10VDC to 16VDC is connected to the
LoadMan 200 Meter at pins 1 and 2 to power the system.
3. Check the connection of the cable harness from the fork box to
the arm box.
4. Check that the fork loadcells are connected to the fork box.
Step 2: Verify the Angle Sensors
In this step you will verify the weigh-in-motion window, which
establishes the angular set point at which the sensors will start and end
the weighing of each load.
1. Power on the LM400 Touch.
2. Press and hold the Power button to display the Setup menu.
3. Tap Troubleshoot and tap Arm/Fork Angle Settings.
4. Verify that “Wgh Start” is set to 0.0.
If it is not, tap the field and use the popup keypad to reset the
angle to 0.0.
This is the angular set point at which LoadMan starts weighing a
load.
Rev 11.2013-1
23
ADMINISTRATION
2. Check the connection of the cable harness from the LoadMan
meter to the arm box.
Initial Startup and Calibration
Tap the field...
...to display the keypad
5. Verify that “Wgh End” is set to 30.0.
If it is not, tap the field and use the keypad to reset the angle
to 30.0.
This is the angular set point at which LoadMan finishes weighing a
load.
6. Verify that “Wgh Dump” is set to 65.0. If it is not, tap the field and
use the keyboard to reset the angle to 65.0.
This is the angular set point at which LoadMan weighs the empty
container.
7. Tap the red arrow to return to the Troubleshoot menu.
Step 3: Verify Fork Loadcells Respond Correctly
1. On the Troubleshoot menu, tap Loadcell.
2. Verify that the span for CH1 (channel 1) is 1090000.
Channel 1 corresponds to the left fork cell. This is the normal
sensitivity for channel 1, and should not be changed.
24
Rev 11.2013-1
Initial Startup and Calibration
3. Move the forks to a horizontal position and make a note of the
CH1 loadcell reading (it will normally bounce around ±20 counts).
4. Raise the forks as near to vertical as possible. In this position
the loadcell reading should decrease 400-2500 counts from
the horizontal fork reading. If it does, the loadcell is responding
correctly and you can skip the next step.
NOTE If the reading increases while raising the fork to the
vertical position (rather than decreasing), it indicates that
the loadcell is mounted upside down. The loadcell should
be remounted to correct the problem.
5. Repeat this procedure for the CH2 (channel 2) loadcell, which
corresponds to the right fork cell.
Step 4: Zero the Arm Angle
2. Move the arms to the desired start position of the weigh-in-motion
window.
Under normal conditions, this is the position of the arms when
lifting a typical container to about 1-2 feet off the ground.
3. When the arms are in position, tap Yes.
4. To verify the arm angle, tap Troubleshoot, and then tap Arm/Fork
Position.
Check the following:
• The Arm Zero value should be within 1000 counts of zero.
• The Arms (arm angle) should read zero degrees when the arm
is in a position that would lift a typical container 1-2 feet off the
ground.
• The Arms value should increase as the arms are raised higher.
5. Tap the red arrow to return to the Setup menu.
Step 5: Zero the Fork Angle
1. On the Setup menu, tap Zero Fork Angle.
Rev 11.2013-1
IMPORTANT This next step is critical. The internal
calibration assumes that the forks are accurately horizontal
when the fork angle displays zero. Any error here will cause
an error in the weight measurements.
25
ADMINISTRATION
1. On the Setup menu, tap Zero Arm Angle.
Initial Startup and Calibration
2. Using a level, move the forks until the vertical plate welded to the
forks is vertical.
The level should be used on the vertical fork mounting plate—not
the forks, as the forks are usually tapered.
3. When the forks are in the horizontal position (or more importantly,
the fork mount plate is accurately vertical), tap Yes.
4. To verify the fork angle, tap Troubleshoot, and then tap Arm/Fork
Position.
Check the following:
• The Fork Zero value should be within 1000 counts of zero.
• The Forks (fork angle) value should read zero degrees when the
forks are in the horizontal position (that is, the fork mount plate is
vertical).
• The Forks value should increase as the forks are raised higher.
5. Tap the red arrow to return to the Troubleshoot menu.
Step 6: Verify Angle Measurements Respond
Correctly
1. On the Troubleshoot menu, tap Arm/Fork Position.
2. Lift a container from the ground until the Arms (arm angle) reads
0.0 degrees.
The container should be 1 to 2 feet off the ground when the Arms
reading is 0.0 degrees. Also, the arm angle should increase as the
arms are raised and decrease as the arms are lowered.
3. Verify that the ARM ZERO value is within 1000 counts of zero. If it
is not, repeat the instructions in “Step 4: Zero the Arm Angle.”
4. Position the forks until the fork angle (Forks) reads 0.0 degrees.
At the Forks 0.0 degrees reading, the forks should be horizontal
or more importantly, the fork mounting plate surface should be
vertical. Also, the fork angle should increase as the forks are raised
and decrease as the forks are lowered.
5. Verify that the Fork Zero value is within 1000 counts of zero. If it is
not, repeat the instructions in “Step 5: Zero the Fork Angle.”
26
Rev 11.2013-1
Initial Startup and Calibration
Step 7: Verify Weigh-In-Motion Response
1. Display the Operations screen.
To display the Operation screen, tap the red arrow to return to the
Setup menu, and then tap the red “X.”
On the Operations screen, the status message should show
“Ready to Weigh.”
2. Raise the arms up through a complete weighing cycle. If everything
is working properly the system should respond with the following
status messages:
• “Weighing Load” while the arms are in the weigh-in-motion
window.
• “Gross xxxxx LB” as the arms pass the end of the weigh-inmotion window.
3. Lower the arms. The following status messages should appear:
• “Lower Arms” while passing down through the dump set point.
• “Weighing Tare” as the arms pass down through the weighing
window.
• “Net xxxxx LB” after the arms have passed below the start point
of the weigh-in-motion widow. This is the net payload that was
measured and dumped into the vehicle.
• “Recording Weight” indicates that the weighing process is
complete and the load has been recorded.
After a few seconds, the LM400 Touch should indicate that it is
ready for the next load with the message, “Ready to Weigh”.
4. If the responses were correct, proceed to “Step 8: Calibrate Zero
Fork Load.” If not, return to “Step 2: Verify the Angle Sensors” and
repeat the process until everything working correctly.
Rev 11.2013-1
27
ADMINISTRATION
• “Dump xxxxx LB” and “Load xxxxx LB” (alternating) when the
arms pass through the dump set point. This message indicates
that the Record Load Data and Auto Accumulate functions have
been armed.
Initial Startup and Calibration
Step 8: Calibrate Zero Fork Load
In this step you will calibrate the fork load sensors to a net weight of
zero.
1. From the Operations screen, press and hold the Power button to
display the Setup menu.
2. On the Setup menu, tap Troubleshoot, and then tap Arm/Fork
Angle Settings.
3. Verify that the Arm Direction and Fork Direction are currently set
to show negative weights. If not, tap the field to change the setting
from positive to negative.
4. Tap the red arrow to return to the Setup menu, and then tap
Settings.
5. Tap Set Display and set the CountBy field to 1.
When finished, tap the red arrow to return to the Setup menu.
6. On the Setup menu, tap Zero Fork Load and follow the on-screen
instructions.
The forks are now calibrated to zero and the system is ready to
weigh. Next, you will calibrate the forks as they are raised and
lowered.
7. Calibrate the forks going up:
a. Display the Operations screen.
b. With no load on the forks, very slowly raise the arms
and forks through the weighing window to verify that the
Gross xxxxx LB measurement is 0 while the forks are
going up.
c. Perform several slow lifts going up to find an average gross
weight. If the average is zero, skip to step 8 in this procedure.
d. If the average gross weight going up is not zero, note the
variance and follow these steps to fine tune the meter:
• Access the Setup menu.
• Tap Troubleshoot, and then tap Calibration.
• Edit the ZeroCalUp setting to account for the variance in
average gross weight.
For example, if the average gross weight was -10 pounds
going up, you would decrease the ZeroCalUp setting 10
counts from the current setting. If the current setting
28
Rev 11.2013-1
Initial Startup and Calibration
is zero (0), this would mean setting ZeroCalUp to -10
(negative 10).
NOTE If the weight is in kilograms (KG), change the
count 2.2X larger than the LB mode.
e. Return to the Operations screen and perform several slow lifts
going up to verify that the Gross xxxxx LB averages zero (0).
Next you will verify that the fork load going down is calibrated to
zero.
8. Calibrate the forks going down:
a. With no load on the forks, slowly raise, and then very slowly
lower the arms through the weigh-in-motion window to verify
that the Net xxxxx LB measurement is zero while the forks
are going down.
ADMINISTRATION
b. Take several measurements going down to find an average
net weight. If the average is zero, then skip this next fork
calibration step.
c. If the average net weight going down is not zero, note the
variance and follow these steps to fine tune the meter.
• Access the Setup menu.
• Tap Troubleshoot, and then tap Calibration.
• Edit the ZeroCalDn setting to account for the variance in
average net weight.
For example, if the average net weight is +10 LB going
down, you would increase the ZeroCalDn setting 10 counts
from the current setting. If the current setting is zero (0),
this would mean setting ZeroCalDn to 10 (ten).
NOTE If the weight is in kilograms (KG), change the
count 2.2X larger than the LB mode.
• Return to the Operations screen and verify that the
Net xxxxx LB averages zero (0) over several slow test
weights.
Step 9: Calibrate System Under Load
This step requires an empty container of known weight.
1. Display the Operations screen.
2. Lift a container with a known test weight, and take note of the
weight reading.
Rev 11.2013-1
29
Initial Startup and Calibration
3. Access the Setup menu.
4. Calibrate the scale:
a. Tap Set Span.
b. In Enter Meter Load, enter the weight that registered on the
meter.
c. In Enter Cal Load, enter the actual weight of the container.
The scale is automatically re-calibrated.
5. Return to the Operations screen.
6. When the status is Ready to Weigh, slowly pick up the empty
container and move it up through the weigh-in-motion window.
Then, lower the empty container through the weigh-in-motion
window at the slowest speed possible. Do this several times to
obtain an average Net xxxxx LB reading going down.
7. If the Net xxxxx LB reading is not zero (0), do the following to
correct the error:
a.
Access the Setup menu.
b. Tap Troubleshoot, and then tap Calibration.
c. Use the following ratio calculation to determine how much to
increase or decrease the SpanCalDn setting:
Ratio = Gross Weight Going Up ÷ (Gross Weight Up – Net
Weight Down)
For example, if the average Net weight reading is +20 LB
and the average Gross reading is 720 LB, the system going
down is measuring only 720-20 = 700 LB. To correct this, the
SpanCalDn value needs to be adjusted by the ratio: 720÷700
= 1.02857.
d. Multiply the current SpanCalDn value by the ratio you
calculated and enter this new setting in the SpanCalDn field.
8. Repeat steps 5 through 7 until the weights going up and going
down are equal, and the Net xxxxx LB reading is zero (0).
Once this calibration procedure is completed, the SpanCalUp
and SpanCalDn values may not be equal, but they should not be
different by more than 500 counts for a system that is operating
properly.

The calibration settings enable LoadMan to account for the natural
variation in weight measurement as the arms are raised and lowered,
and allow LoadMan to convert the weight reading from the sensors
(which is delivered in “counts”) to an actual weight measurement in
pounds or kilograms.
There are three types of calibration settings:
• Zero offset—(ZeroCalUp and ZeroCalDn) adjusts for the variation
in weight measurement as the arms are raised and lowered.
• Span—(SpanCalUp and SpanCalDn) sets the scale to be applied
as the arms are raised and lowered.
• Sample deviation—(SampleDevUp and SampleDevDn) filters out
the measurement “spikes” that naturally occur.

Troubleshooting Common Error Messages
LoadMan must receive the following four sensor signals in order to
display the valid weighing display message “Ready to Weigh.”
• Left Fork Loadcell Signal
• Right Fork Loadcell Signal
• Fork Angle Sensor Signal
• Arm Angle Sensor Signal
If any of these signals are not detected, LoadMan suspends all
weighing functions and displays up to three of the following diagnostic
messages:
• No Arm Sensor! or Arm Sensor OK!
• No Rghtfork Sig! or Rghfork Sig OK!
• No Leftfork Sig! or Leftfork Sig OK!
No Arm Sensor!
This message is displayed when there is no communication to the
arm box. The arm box contains a microcomputer and arm angle sensor.
The microcomputer gathers all three sensor signals (arm signal, left fork
signal, and right fork signal) and communicates their measurements to
the LM400 Touch in-cab computer for processing and display. If the
meter cannot detect the arm box, the message NO ARM BOX SIGNAL
displays. Note that it is possible for the arm sensor to malfunction while
the fork sensor still functions properly.
62
Rev 11.2013-1
Troubleshooting
There are several possible sources of this problem:
• The cable connection from the LM400 Touch to the arm box has
failed.
Action: Check that the 7 pin male connector is firmly plugged into
the arm box mounted on the arm of the vehicle.
• The meter cannot find the arm box.
Action: To verify, use the Voltage and Battery option on the
Troubleshoot menu to check if the CAN bus voltage is correct and
check if the arm box is getting power from the meter (the VLC1
voltage reading). See “Voltage and Battery” on page 58.
• The arm box has failed. This unit is a potted assembly to survive
harsh outdoor environments.
Action: The unit is not field-repairable and must be replaced or
rebuilt.
• The LM400 Touch has failed.
Action: To verify, use the Voltage and Battery option on the
Troubleshoot menu to check that the can bus voltage is correct,
and that the arm box is getting power from the meter (the VLC1
voltage). See “Voltage and Battery” on page 58. If the meter has
failed, it must be replaced with a new or rebuilt unit.
• The software is malfuctioning.
Action: Call your local dealer for assistance.
No Leftfork Sig! and No Rghtfork Sig!
TROUBLESHOOTING
If these two messages are displayed together with “No Arm Sensor!,”
refer to the previous section. If these two messages are displayed
together with the message “Arm Sensor OK!” read this section for
assistance.
The microcomputer inside the arm box reports whether it is receiving
the fork loadcell signals. The fork box contains the digital to analog
converters for both the right and left fork loadcells and also the fork
angle sensor, which is independent of the arm angle sensor.
LoadMan must receive both loadcell signals.
To troubleshoot
1. Check the cables that connect the arm box to the fork box and
verify that they are plugged tightly into each module.
Rev 11.2013-1
63
Troubleshooting
2. If the cables are connected securely, check the cable harness for
damage and perform a continuity check.
The cable harness has a 7-pin connector on each end, and all
connections go pin-to-pin (pin-A to pin-A, pin-B to pin-B).
3. If the cable is okay but the messages “No Leftfork Sig!” and “No
Rghtfork Sig!” continue to display, do the following:
a. Attempt to disconnect both loadcell cables that plug into the
fork box to eliminate a fault in one or both of the loadcells.
b. Check that the fork box is receiving a signal from the loadcell
by using the Load Cell option on the Troubleshoot menu (see
“Loadcells” on page 59). Check the values for CH1 and CH2.
4. If the messages continue to display, there is a problem with the
fork box.
The fork box is a potted assembly to survive harsh outdoor
environments. The unit is not field-repairable and must be replaced
or rebuilt.
No Leftfork Sig! but Rghtfork Sig Ok!
If one of the loadcell signals is present but the other is not, it is most
likely that one of the loadcells has failed. Swap the two loadcells on the
fork box and see if the error message reverses. If it does, this confirms
that one of the loadcells has failed. Swap the loadcells again to make
certain which loadcell has failed. When isolated, replace the failed
loadcell.
Leftfork Sig Ok! but No Rghtfork Sig!
Refer to the previous section.
Other Issues
This section addresses common issues that do not produce error
messages.
Load Measurements are Inaccurate
Load measurements that are not repeatable or are inaccurate can be
traced to one of the following:
• One or both loadcells have failed.
• The fork digital to analog converter (LoadCoder) has failed.
64
Rev 11.2013-1
Troubleshooting
• Fork angle measurements are faulty.
• Arm angle measurements are faulty.
Checking the Loadcell Response and Fork LoadCoder
1. Move the forks to a horizontal position.
2. On the Setup menu, tap Troubleshoot.
3. Tap Loadcell.
4. Verify that the Weight reading for CH1 (the left loadcell) reads near
0 counts.
The “Weight” is the current weight reading of the CH1 loadcell.
These readings are not actually calibrated in LBs but instead are
10 times the actual LB weight. And since the sensitivity is 10x, the
count will bounce around ±20 counts.
If the weight reading for CH1 is not near 0 counts, zero the fork
load (see page 45).
5. Raise the forks to as near vertical as possible, and check the
CH#1 Weight.
When raising the forks near vertical, the load on the forks comes
off the loadcell and the reading should decrease 400-1000 LB
counts (depending on the weight of the forks). If the reading does
not decrease by this amount, this is an indication that the loadcell
is bad.
6. Pick up an empty container and verify that the loadcell reading is a
positive value.
If the loadcell reading is a negative value under load, it indicates
that the loadcell is mounted upside down and must be removed
and rotated 180°.
If the loadcell reading bounces hundreds of counts, drifts, or
does not repeat the same reading under a given container load, it
indicates one of the following conditions:
• Loadcell has failed.
• Fork box analog to digital converter has failed.
• Loadcell cable is damaged.
• Connector is loose and has moisture or dirt in the contacts.
7. Check for damaged loadcell cables or dirty contacts. If the
contacts are dirty, clean the pins with isopropyl alcohol and a
Q-tip.
Rev 11.2013-1
65
Troubleshooting
The signals on these pins are on the order of less than one
millionth of a volt, so any film residue or moisture on the contacts
can cause loadcell signals to drift wildly.
8. If the problem persists after cleaning the contacts, the fork box
should be replaced.
9. If replacing the fork box does not fix the problem, the loadcell
should be replaced.
10. Repeat steps 1 through 8 for the CH#2 (right) loadcell.
Checking Fork and Arm Angle Measurements
LoadMan relies on the accuracy of the fork and arm angles to
determine accurate weight measurement results. The loadcell weight
measurement response is a direct function of the fork angle. Any error
in the fork angle will have a major impact on the overall accuracy of the
weighing system.
The arm angle also informs LoadMan when to look at the fork loadcell
signals. Any error in the arm angle can cause LoadMan to look at
the loadcell weight measurement response in the wrong part of the
weighing cycle.
To check the fork angle calibration
1. On the Setup menu, tap Troubleshoot.
2. Tap Arm/Fork Position to view the current fork angle.
3. Place a level on the fork mounting plate and move the forks until
the fork mounting plate is perfectly vertical (this ensures that the
forks are perfectly horizontal).
4. When the fork mounting plate is vertical, the “Forks” reading
should measure 0.0 degrees. If it does not, go to “Step 5: Zero
the Fork Angle” on page 25 and follow the instructions for
calibrating the fork angle.
To check the arm angle calibration
1. On the Setup menu, tap Troubleshoot.
2. Tap Arm/Fork Position to view the current arm angle.
3. Lift a typical container 1 to 2 feet off the ground, and check that
the arm angle reading is 0.0 degrees.
4. If the arm angle is not 0.0 degrees, go “Step 4: Zero the Arm
Angle” on page 25 and follow the instructions for calibrating the
arm angle.

Cell State Codes
Appendix C - Cell State Codes
The Cell State Code indicates the current state of the modem and
is displayed when you troubleshoot modem communications (see
“Modem Communications” on page 53). This code may be requested
by LoadMan technicians to help you diagnose a communications
problem. Although the CELLSTATE number can be as high as 200,
generally any number of 80 and above means that communications are
established.

LoadMan Load Management Software
Appendix F - LoadMan Load Management Software
This appendix describes the LoadMan Load Management software
(LLM) and provides instructions for downloading the unlicensed version
of the software to your PC and configuring a connection to the LM400
Touch.
Software Features
The LoadMan Load Management software (LLM) allows remote tracking
of trucks, drivers, customers, routes and products by account or job.
The unlicensed version of this software can be installed on your PC and
used to perform software updates on the LM400 Touch or to download
route information to the LM400 Touch.
LoadMan offers two versions of the LLM software:
• LoadMan Load Management for Waste and Recycling
• LoadMan Load Management for Mining and Steel
These two products are very similar, and each offers a user interface
and features that are customized for the specific industry served. The
data collection memory of each fleet truck can be accessed by the
software to gather the following information:
• Routes, vehicle ID, driver ID, and customer accounts
• Products hauled or delivered—by account or job
• Load weights, load sites and commodity
• Truck and load locations by GPS coordinates
• Problems encountered (waste and recycling)
• Commodity and mix recipes (mining and steel)
• Time and date stamp on all loads
This load data is uploaded to a back office management database,
where load data can be further studied by date, customer, account,
driver, and other data points. The data can also be exported to popular
accounting and spreadsheet programs.
For more information about LoadMan Load Management software and
to view a video demonstration, visit our LoadMan website: http://www.

website at http://www.loadman.com/truck_scales_contact_dealer.
To download and install LLM
1. Open an Internet browser and go to the following
website: http://loadmansoftware.com/
2. Click the link LoadMan Software for Windows.
3. Enter the following username and password:
Username: Release
Password: NewStuff
4. Scroll down and click the link LoadmanSetup_xxxxx.exe (where
“xxxxx” is the version number).
In the following example, this link is “LoadmanSetup_70113.exe.”
5. Click Run in the two dialog boxes that appear.
This starts an Installation Wizard that will download and extract the
software.
6. Follow the installation instructions as they are presented in the
Wizard.

Configuring a COM Port Connection
Once you have installed the LoadMan Load Management (LLM)
software on your PC, you are ready to configure a COM port
connection to the LM400 Touch.
There are two ways you can connect to the meter:
• Use a USB to RS232 serial connection cable to directly connect
a USB port on the PC to the RS232 port (Port 1) on the LM400
Touch.
This cable can be ordered from LoadMan.
OR
• Use a wireless Bluetooth connection on the PC to connect to the
LM400 Touch Bluetooth port.
The Parani SD100 is a common Bluetooth connector used to
repurpose a USB COM port on a PC for Bluetooth.
To configure the connection to the LM400 Touch
1. Connect the USB to RS232 serial cable to a USB port on the PC
OR
Connect a Bluetooth connector to a USB port on the PC.
