INTRODUCTION The LoadMan® LM310 is a precision instrument capable of running and controlling many different vehicle weight measurement applications. The Application Software documented in this manual supports LoadMan’s Weigh-In-Motion Cart Lifter Weighing Systems. These Weighing Systems are usually mounted on vehicles that weigh residential carts in motion – as they are picked up, dumped, and lowered to the ground. The LoadMan® system is completely automatic and the driver/operator does not need to press any buttons or take any actions to obtain a weight reading. The 16 character display provides all the information needed to understand the status of the weighing system. For example, the meter automatically provides the following instruction displays during the weigh-in-motion process: READY TO WEIGH The cart lifter arm is below the start of the weighing

window and the system is ready to begin weighing.

WEIGHING LOAD Message while cart is lifted up through the weighing window.

GROSS WEIGHT Displays weight of the cart and its gross load weight.

DUMP LOAD Weighing is complete and load is ready to dump. The gross load weight measured going up is still displayed.

WEIGHING TARE Measuring the empty cart weight while cart is coming down.

NET WEIGHT Displays the computed net weight of the dumped material.

TRUCK Displays the accumulated load net weight that has been dumped into the truck.

LM310 –An onboard in-cab-meter for displaying weight, route and system

information. ARM310 – A computer based arm weigh-in-motion assembly mounted on

the arm of the cart lifter (bolted to the lift arm of the cart lifter). CART310 -- A cart weigh-in-motion assembly mounted between the two

mounting plates which support the cart lifter assembly.

Figure 1. ARM310 Connected with CART310

The CART310 weigh-in-motion assembly converts the sensitive analog data signals from the two cart lifter loadcells to digital, using a precision digital to analog encoder called a CanCoder™. It also receives the angular position of the cart lifter arms measured by the ARM310 along with speed; converts the information to digital, and transmits the data up the LM310 meter for display and processing. The ARM310 weigh-in-motion assembly also contains an angle sensor; so the weighing system not only knows the position and speed of the cart lifter, but also the angular position and speed of the lift mechanism at all times. The CART310 cart box computer gathers the weight measurement from the cart lifter loadcells, the lift arms angular position and speed from the ARM310. It then processes this information to determine the weight of the cart plus its contents while going up (gross weight). Then, in the same manner, measures the tare weight of the cart going down. The difference between these two weights determines the net weight of the material that was dumped into the truck (NET). All of this information is transmitted to the LM310 in-cab meter and displayed to the driver/operator. The load data record can wirelessly transmit to LoadMan’s

Introduction

Load Management Software if the data collection software is operating in the back office. LoadMan's Load Management Software 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 LoadMan® meter. Any recorded load data and/or GPS position data in LoadMan’s data collection memory will be automatically transferred to the Load Management Software - without any prompting or intervention from the driver – whenever a wireless modem or wireless Bluetooth connection is established between the truck’s LM310 computer and the back office software.

OPERATIONAL BASICS This section will introduce the operational basics of the LM310 LoadMan® Meter. Anyone new to the use of the LoadMan® Meter should first read this section to become familiar with: Front panel display Keypad definitions and use Basic navigation Programming basics Connectivity & Communications LoadMan Load Manager Software

Power Connecting power at the rear panel causes LoadMan to power on, displaying the message “LOADMAN”, followed by “PROG VERSION X.X”. The Program Version number X.X represents the application software version and aids in tracking software updates. With power on, and within any operating mode, momentarily pressing the

POWER button causes LoadMan to briefly display the “GOODBYE!“ message.

When power is applied, the message “CYCLE ARMS” may appear if the cart lifter is not in the READY TO WEIGH position. Repositioning the Cart Lifter Arm to the normal Ready to Weigh position will return the display to “READY TO WEIGH”.

Operational Basics

12

LoadMan Front Panel and Display As shown in Figure 2, the LoadMan LCD display has a 16 character alphanumeric field for displaying operational messages as well as setup and calibration instructions. There are 6 push-buttons used for power, programming and display selection.

Figure 2. LoadMan LM310 Meter Front View

PROGRAM Keys

These PROGRAM keys are used to enter a command (like ZERO TRUCK), print a load record (PRINT LAST LOAD), change a programmable number (like setting the TRUCK tare weight in Setup & Calibration), or setting the Date and Time. If a selected display is programmable, pressing the PROGRAM key will

initiate a flashing cursor in the display, signifying that LoadMan has entered the Program Mode.

For programmable displays, use the PROGRAM key to move the flashing cursor left to the next programmable digit/item in the display.

Once the flashing cursor is positioned over the item to be changed, use the PROGRAM key to increase/bump the digit/item to its next value.

Continue to use the /PROGRAM keys until the display has been programmed to the correct value.

The PROGRAM key will execute the command and save any changes SET

made to the display.

Operational Basics

13

LoadMan will take NO action on selections and/or changes until the

PROGRAM key is pressed. And, if a selected display is not SET

programmable, pressing any of the PROGRAM group of keys will have no effect.

SELECT Keys

The SELECT keys are used to manually scroll through any of the currently available vehicle weight displays and route information. These keys are also for scrolling through setup & calibration command options. The SELECT key will sequence forward through a group of displays. The SELECT key will sequence in reverse through a group of displays.

Weight and Message Display

Any weight information, route information or status message information shown on the 16 character display will depend on the overall setup and configuration of the LoadMan Meter (discussed in later sections).

LoadMan Operating Modes LoadMan has two distinct operating modes: the Normal Operating Mode and Setup & Calibration Mode. Introduction to Normal Operating Mode At power on, LoadMan enters the Normal Operating Mode which provides the main operational, messaging and status information for the LoadMan weight and route applications. Table 1. Normal Operating Mode Display contains a list of display messages that can be manually accessed using the /SELECT keys, or automatically cycle displayed. Introduction to Setup & Calibration Mode LoadMan’s Setup & Calibration Mode provides the operator the capability to program advanced functionality, choose optional information displays, enable communications, and to setup and calibrate a truck’s configuration. The top level command options are summarized inTable 6, and detailed programming of these options will be discussed in the section titled Setup & Calibration Mode later in this guide. Also, a detailed command tree is located in Appendix B –

Connectivity & Communications RS232 Ports LoadMan comes standard with one RS232 port (9-pin female connector) that is a available for connecting peripheral devices like printers, barcode wands, etc. During setup and configuration, this is referred to as RS232 port #1. RS232 Port #2 (9-pin male connector) is not available for connecting peripherals. This port is dedicated to factory configuration and service diagnostics. Wireless Communications The LoadMan meter may come equipped with an optional Bluetooth wireless modem, or a GSM cellular modem. The modem is used to connect and communicate with LoadMan’s Load Manager Software. If the Bluetooth option is ordered, it will occupy RS232 Port #1. The 9-pin female connector described above will become RS232 Port #2. The GSM cellular modem is separate dedicated antenna port. The Load Manager Software allows remote tracking of trucks & drivers, plus customer accounts and route location; and exchanges the load records and location information through one of these modems. GPS The LoadMan meter may also come equipped with an optional onboard GPS modem and antenna. When recorded GPS coordinates are uploaded into LoadMan’s Load Manager Software, office management can use the latitude/longitude coordinates to track truck routes and aid with several other advanced location based functions from the office. Refer to Figure 4. LoadMan Connectivity Example.

Weight and Information Displays

INFORMATION DISPLAY – This display is where the weigh-in-motion system

normally operates. It has been set up to automatically provide the operator all the instructions and information needed to run the in-motion weighing system.

CYCLE ARMS Infrequently – if the cart lifter arm is not in the READY TO WEIGH position at power on, this message informs the operator to re-position the cart lifter arm back to the READY TO WEIGH position so weighing can begin.

READY TO WEIGH

Informs operator that the cart lifter weigh-in-motion system is ready to weigh.

WEIGHING LOAD

This message is displayed once the cart lifter arm has reached the start of the weighing window. There is no need to stop the arm during the weighing sequence as LoadMan computes the weight while the arm is in-motion.

GROSS xxxxxx Gross weight of the loaded cart – once the arm has been raised above the weighing window. xxxxxx represents the gross weight of the cart and its contents.


25

DUMP xxxxxx LOAD xxxxxx These two messages display alternately to inform the operator to complete the lifting process by completely dumping the load. xxxxxx represents the gross weight of the container and contents.

If the arms are lowered before reaching the programmed DUMP set point, LoadMan ignores the weight and display the message, “IGNORING LOAD!”.

LOWER ARMS LoadMan displays this message once the load has been dumped and the arm is being lowered.

WEIGHING TARE Message displayed as the emptied cart is being weighed – while the arm continues lowering below the weighing window.

NET xxxxxx Displays the net weight where xxxxxx represents the weight of the material just dumped into the truck.

RECORDING LOAD The message indicates that the weigh-in-motion process has successfully completed and the net weight has been entered into the load record. Additionally, the recorded net weight is added to the accumulated total weight of the TRUCK.


26

WEIGHT DISPLAYS – While in the Normal Operating Mode, LoadMan presents various weight displays, some of which can be configured in the INSTALL/SET DISPLAYS group of the Setup & Calibration commands (see the section on Setup & Configuration Mode for instructions on choosing optional weight displays). LAST xxxxxx LB – Displays the net weight of the contents dumped from

the last cart picked up and weighed.

TRUCK xxxxxx LB – Displays the total net weight of the contents dumped into the truck for all containers since the last ZERO TRUCK command was executed. (See PROGRAM FUNCTION below for executing the ZERO TRUCK command).

TARGET xxxxxx LB – This is a programmable display that shows the current target net weight set point. When turned on, this display allows the operator to set a target net truck weight that will activate an alarm when exceeded. (To enable the TARGET display, use the INSTALL/SET DISPLAYS/TARGET SETPT->ON command in Setup & Calibration). To program the TARGET weight: In the Normal Operating Mode locate the TARGET display using the

SELECT key. Now use the /PROGRAM keys to program the target load

weight.

Press PROGRAM to set and activate the target weight. SET

Software Alarm – To enable an overload display message when the TARGET net truck weight is exceeded, use the INSTALL/SET DISPLAYS/FLASH OVERLD command in the Setup & Calibration mode. So in the normal operating mode, the message “GROSS >>> TARGET” displays any time a net truck weight exceeds the target weight (“NET >>> TARGET” when in the NET display mode).


27

Hardware Alarm – To activate a hardware alarm (like a light or buzzer), an overload hardware signal will short to ground whenever the net truck weight exceeds the TARGET set point value. See Figure 8. LM310 Wiring Diagram for Cart Based Weight System.


While in the Normal Operating Mode, LoadMan presents various optional displays that can be configured in the INSTALL/SET DISPLAYS group of the Setup & Calibration commands (see the section on Setup & Configuration Mode for instructions on choosing optional status displays).

LOAD NAME & ACCOUNT # – Configuring these two optional displays allows the operator to display, select and record a Load Name and its associated Account Number for every load in a pickup route. This display function can be turned on or off by using the INSTALL/SET DISPLAYS/FLASH LDNAME, FLASH ACCT# and FLASH STOP# commands in the Setup & Calibration Mode. When these options are turned on, the Load Name, Account Number and/or Stop Numbers will flash on the LoadMan display. This helps the driver identify the pickup account.

When enabled, up to 940 sixteen unique alphanumeric character load names along with their associated seven digit account numbers can be downloaded from LoadMan’s Load Manager Software. The Stop Number is the sequence number the pickups were loaded into LoadMan from Load Manager Software. Load Manager Software uses various communication methods (such as wireless Bluetooth or cellular modem) to connect and download route and account information. When the Load Manager software downloads route information to the LoadMan meter, the number of Load Names, Account Numbers and Stop Numbers are set automatically.

The load name, account number and stop number combination is tied to each load to be picked up on the operator’s route. When a load is recorded – confirmed by the RECORDING LOAD information display message – the currently displayed load name, account number and stop number are recorded into LoadMan’s data collection memory. After all of the load and route information is recorded, LoadMan automatically sequences to the next load name/account number in the route list (if enabled with the SET


28

RECORD Option of the Setup and Calibration Mode).

Unexpected departures from the planned sequence in the route list can be managed using the PROGRAM group of keys to select an out of sequence stop and load or by using account barcodes from a Route Sheet. Use Geo Routing Mode to only display those accounts within defined radius (300 to 1000 feet) of the Trucks location. Refer to the section Collecting Load Data for details.

STOP # xxx – In addition to the optional Load Name and Account Number, every load has a Stop Number (#) that is recorded in LoadMan’s data collection memory whenever a load is recorded. The Stop Number represents the sequence in the route list of Load Names and Account Numbers that have been downloaded by the LoadMan Load Management Software. The Stop Number is programmable and allows the operator to select accounts by programming any stop number that has been previously loaded into its memory from Load Manager Software. Each time a load is recorded, LoadMan automatically increments the stop number (if enabled with the INSTALL/SET RECORD/INCR STOP# command). This optional display function can be setup to flash during a weight display using the INSTALL/SET DISPLAYS/FLASH STOP# command in the Setup & Calibration Mode.

The stop number is reset to one (1) whenever LoadMan’s Load Manager Software downloads route information.

The operator can override the current stop number by using the PROGRAM group of keys to program a desired stop number. Refer to the section Collecting Load Data for the out of sequence instructions.

PRODUCT NAME – LoadMan allows up to 50 different Product Names to be

captured whenever a load is recorded into the data collection memory. (These product names can be downloaded with LoadMan’s Load Manager Software.) This optional display function can be setup to flash a PRODUCT NAME during a weight display by using the INSTALL/SET DISPLAYS/FLASH PRODUCT command in the Setup & Calibration Mode. When the Load Manager Software downloads route information to the LoadMan meter, the


29

number of Product Names is set automatically.

When enabled, and before a load is recorded, the operator can select a product name (e.g., RECYCLE, CARBOARD, COMPOST, etc.) that will be recorded in LoadMan’s data collection memory. To choose a product name: Locate the current PRODUCT display using the /SELECT keys. Locate the particular product name using the /PROGRAM keys.

Activate the product name with the PROGRAM key. SET

When a load is recorded – confirmed by the RECORDING LOAD information display – the product name is recorded into LoadMan’s data collection memory along with the account name, account number, stop number and any other enabled route options.

Once a product name has been selected, it remains in effect for all subsequent load recordings. The product name should be re-programmed whenever the product condition changes.

EVENT – LoadMan provides up to 50 different Event Conditions that can be recorded whenever a load is recorded into the data collection memory. (These event conditions can be downloaded with LoadMan’s Load Manager Software.) This optional display function can be setup to flash an EVENT condition during a weight display by enabling the function with the INSTALL/SET DISPLAYS/FLASH EVENT command in the Setup & Calibration Mode. When the Load Manager software downloads route information to the LoadMan meter, the number of event conditions is set automatically.

When enabled, and before a load is recorded, the operator can select an event condition (e.g., ROAD CLOSED, CONTAINER LOCKED, etc.) that will be recorded in LoadMan’s data collection memory. To choose an event condition: Locate the current EVENT display using the /SELECT keys. Then locate the particular event condition using the /PROGRAM

keys.

Activate the event/problem condition with the PROGRAM key. SET

When a load is recorded – confirmed by the LOGGING EVENT information display – the Event condition is recorded into LoadMan’s data collection memory along with the account name, account number and any other


30

enabled route options.

Once an event condition has been selected and recorded, it reverts back to the NO EVENT condition for all subsequent load recordings. New event conditions should be re-programmed anytime an event or problem is encountered, and before a load is recorded.

DATE and TIME – The currently displayed Date and Time is recorded in LoadMan’s data collection memory whenever a load is recorded into the data collection memory. This display function is not optional. Programming DATE and TIME – Using the programming basics discussed in the previous section, the date and time can be changed with the PROGRAM keys: Locate the Date and Time display with the SELECT key. Now use the /PROGRAM keys to program the time (hours, minutes,

AM/PM) and date (month, day, year).

Press PROGRAM to set and activate the new time. SET

ZERO CART LOAD – Zeros the cart lifter loadcells so it will read zero. This command is useful when there is nothing loaded on the cart lift. This command should be used when LoadMan weighs something other than zero when no cart is on the cart lifter when going up and down. If this is the case,


33

executing this command will direct LoadMan to lead the operator through a process to zero the Cart Lifter weight reading. REMOVE CART

Make certain there is no load on the cart lifter. SET ARM ANGLE - LoadMan now displays the ARM Angle. Raise or

lower the arms of the cart lifter to where the cart lifter mounting plate is vertical. When the angle is ±1 degree of zero, LoadMan will zero the Loadcell readings in this static position, and display ZERO COMPLETE to confirm the zero cart load and zero cart angle.

Calibrate System for ZERO CART LIFTER LOAD Switch LoadMan also features a ZERO CART LOAD switch that is mounted on the left outside plate of the cart lifter scales. This light/switch allows the operator to work at the rear of the truck, reading the green strobe light while leveling the cart arm angle to zero.

Depressing this switch initiates the zero load process that was just described above. And it also features a green light strobe that provides real-time feedback on the cart angle. The closer the angle to zero, the faster the light flashes. And when the fork angle is between 0 and +/-1, the light will hold steady.

When finished zeroing the load, the light provides a high frequency “chattering” strobe indicated that the Zero Weight is calibrated accurately. When finished, depress the switch to turn off the light and the zeroing

process.

CYCLE DISPLAY – Directs LoadMan to automatically cycle through all of the available displays (order listed in Table 4. Normal Operating Mode Display). The duration of each item displayed is configurable using the INSTALL/SET DISPLAYS/CYCLE command in the Setup & Calibration Mode (default is 2 seconds).


34

Pressing either the /SELECT keys will terminate the automatic cycle display and allows manual selection of the display by using either of the /SELECT keys.

ZERO TRUCK – Zeros the accumulated TRUCK load total. Thereafter,

TRUCK xxxxxx nLB will display the accumulated net weight of any recorded loads. Or, TRUCK xxxxxx gLB will display the truck’s accumulated gross weight - total of the truck’s tare weight and the accumulated weight of any recorded loads. It is recommended that the driver zero the truck after any transfer station or landfill dump - resetting the accumulator to zero - before continuing the route or starting a new route. ENTER GROSS SCALE WEIGHT! – The ZERO TRUCK command also

features the option to capture the gross platform scale weight of the loaded truck just before a landfill dump. This weight will be recorded and reported to LoadMan Load Manager to assist in tracking all the truck’s tipping weights at landfills and transfer stations. Note that the landfill scale location must be geocoded in order for Load Manager to record the scale weight in the correct landfill customer record.

Activating – Setup & Calibration Mode w/SECURITY ON

Continually depress the POWER button. The messages “GOODBYE!“ and “ENTER PASS CODE!“ will display.

At the prompt, “PASS CODE 0”, use the /PROGRAM keys to program

the security code TO “123”and save the code with the PROGRAM key. SET

If correct, LoadMan displays the message, “LOADMAN SETUP”. The first setup & calibration category displayed is “SET ZERO?---->NO”. If the security code is NOT correct, the error message, “SECURITY FAILED” is

displayed, and the Setup & Calibration mode cannot be accessed. Navigating and Programming – Setup & Calibration Mode The SELECT keys are used to manually scroll through the seven setup, calibration and troubleshooting categories. The SELECT key will sequence forward through a group of displays. The SELECT key will sequence in reverse through a group of displays.

Once the desired setup category is displayed, use either of the /PROGRAM

keys to toggle “NO”, “YES” or other options; and then press the PROGRAM to SET

select and activate the setup category. For programmable displays (like setting a tare weight): Use the PROGRAM key to move the flashing cursor left to the next

programmable digit/item in the display. Once the flashing cursor is positioned over the item to be changed, use the

PROGRAM key to increase/bump the digit/item to its next value. Continue to use the /PROGRAM keys until the display has been

programmed.

The PROGRAM key will execute the command and save any changes SET

made to the display.

LoadMan will abort the process of programming displays if either of the /SELECT keys are pressed.


39

Finally, press the PROGRAM key to exit. SET

LoadMan will now return to the normal operating mode and will reinitiate the information displays of weight and status messages.

Setup & Calibration Commands

SET ZERO – Zeros the cart lifter loadcell weight reading. This command is useful when nothing is loaded on the cart lifter but LoadMan still weighs something other than zero when the cart lifter is going up and down. If this is the case, executing this command will direct LoadMan to lead the operator through a process to zero the cart lifter’s weight reading.

ZERO ARM ANGLE

Use the PROGRAM key to select “ZERO ARM ANGLE?” and activate

with the PROGRAM key. “THIS IMPACTS YOUR CALIBRATION” and SET

then the “PROCEED?NO” comes up. Use the Program Group of keys to change the NO to YES and then press the SET Key.

“POSITION ARMS TO ZERO ARM ANG” and then “READY?-->NO” comes up on the display. Move the cart lifter mounting plates so they are perfectly vertical (recommend using a Level for this step). When ready, use the Program keys to change the NO to a YES and press the Set Key. “ZEROING ARM ANGLE”, then “ZEROING COMPLETE”. The arm angle sensor mounted on the cart lifter arms is now calibrated to read zero in the cart lifter’s current position.

ZERO CART LOAD

LoadMan responds with “REMOVE CART!” and then “SET ARM ANG =0” and then starts displaying the cart lifter arm angle. Raise or lower the cart lifter arms until the angle reading is within ±1 degree of zero. At that point, LoadMan will automatically calibrate the loadcell readings to read zero.


40

LEARN ZERO? – Learn Zero is the process of “custom learning” the zero response of the cart tipper’s loadcells; fine tuning the accuracy of each loadcell. This is accomplished by a series of lifts (12-15 lifts are recommended). Without this procedure the loadcell measurements could be inaccurate and misleading.

The process is quite simple. Just follow the LoadMan display instructions:

Activate with the PROGRAM key. SET

REMOVE CART! – Remove the cart for the entire LEARNING process.

RAISE ARMS! LEARNING ZERO UP LOWER ARMS! LEARNING ZERO DN CYCLES – Displays the number of LEARN cycles completed.

The above process should be repeated from 12-15 times to allow LoadMan to fully determine each loadcell’s zero response; fine tuning the accuracy of each loadcell. When finished repeating this process, simply let the cart lifter rest at zero. LoadMan will provide screen instructions to complete the LEARN process: UPSELECT IF DONE - SELECT. SAVE ZERO? – Use the PROGRAM programming key to choose

“YES”, and confirm with the PROGRAM key. SET

SAVING ZERO DATA – Wait for LoadMan to process before activating any further keys.

SET SPAN – Used to calibrate LoadMan to the readings taken from another scale. Use this setup command to calibrate a truck load of material that has been weighed on another scale; or alternately, calibrate LoadMan to the weight of a loaded cart weighed on another calibrated scale.

Prior to performing SET SPAN setup on a truck load of material, LoadMan must display a ZERO TRUCK net weight when the vehicle is empty. If not, then perform a PROGRAM FUNCTION/ZERO TRUCK command when the vehicle is empty. Otherwise an inaccurate


41

calibration will result.

Prior to performing the SET SPAN setup command with a calibrated container, an empty cart load should measure a net weight of zero. If not, then perform a PROGRAM FUNCTION/ZERO CART LOAD command. Otherwise an inaccurate calibration will result.

SET SPAN Calibration Procedure -- This procedure is used for either

calibrating a loaded cart or for calibrating a single container that is loaded with a calibrated weight that is near 80-100% of the cart lifter’s load capacity.

Use the PROGRAM key to select “SPAN TRUCK?” and activate with

the PROGRAM key. SET

o LoadMan asks for confirmation with “ADJUST SPAN?” Press SET

Program key to confirm. o LoadMan responds with instructions to “ENTER METER LOAD”. o METER xxxxxx LB” – Use the /PROGRAM programming keys to

enter the weight readings obtained from the LoadMan meter. This would be the net (TRUCKn) or gross (TRUCKg) weight for the truck,

or the net load weight (LAST) for a container. Press the SET

PROGRAM key to save. o Press the SELECT key and LoadMan will respond with the

directions, “ENTER CAL LOAD”. o Use the /PROGRAM programming keys to enter the weight

readings obtained from the calibrated scale. Press the SET

PROGRAM key to save. o Now press the SELECT key and LoadMan will respond with the

directions, “DO AUTOCAL?-->NO”. This display is confirming that the weights have been entered properly.

o If a mistake was made when entering the truck’s net (or gross) weight (TRUCKn or TRUCKg) or the calibrated load weight (LAST), simply use the SELECT key to back up and re-enter.

o Once confirmed that the entries are correct, select “YES” and press

. SET

LoadMan will now complete the SPAN calibration and confirm with, “DOING SPAN ADJUST” and “SPAN COMPLETE!”.


42

LEARN SPAN? – Learn Span is the process of “custom learning” the calibration of the cart tipper’s loadcells. This is accomplished by a series of lifts (12-15 lifts are recommended). Without this procedure the loadcell measurements could be inaccurate and misleading.

The process is quite simple. Just follow the LoadMan display instructions:

Activate LEARN SPAN with the PROGRAM key. SET

ENTER SPAN CAL (Factory default is 400LB). Press SELECT key to continue.

ENTER CAL LOAD – This is the calibrated weight of a cart loaded with a known scale weight from another calibrated scale. This load should be tightly secured within the cart for safety, and to make certain there is no abrupt bouncing of the container’s contents during the calibration procedure.

Use the /PROGRAM programming keys to enter the weight

reading obtained from the calibrated scale. Press the SET

PROGRAM key to save, and press SELECT key to continue.

LoadMan will respond with LOAD CAL WEIGHT! and has initiated the LEARN SPAN calibration process:

RAISE ARMS! LEARNING SPAN UP LOWER ARMS! LEARNING SPAN DN CYCLES – Displays the number of LEARN cycles completed.

The above process should be repeated from 12-15 times to allow LoadMan to fully determine each loadcell’s span; fine tuning the calibration of each loadcell. When finished repeating this process 12 to 15 times, simply let the cart lifter rest at zero. LoadMan will provide screen instructions to complete the LEARN process: UPSELECT IF DONE - SELECT. SAVE SPAN? – Use the PROGRAM programming key to choose

“YES”, and confirm with the PROGRAM key. SET

SAVING SPAN DATA – Wait for LoadMan to process before


43

activating any further keys…this may take few moments.

SET TARE – Sets the empty weight of the vehicle – referred to as the tare weight. LoadMan uses the configured tare weight to display the gross weight of the vehicle when LoadMan is configured for gross weight operation (activated by the PROGRAM/SHOW GROSS command). The gross weight is the net weight (or payload weight) plus the tare weight; and it is the tare weight that is set by using this command. First obtain the tare weight by weighing the fully fueled empty truck at a calibrated truck scale, and write down the tare weight here: TRUCK TARE WEIGHT: ______________________________ When the SET TARE category is activated, the message “TRUCK xxxxxx LB” is displayed where xxxxx is the current tare setting for the truck. Use the

/PROGRAM and PROGRAM keys to change and set the truck’s tare SET

setting.

Note that the truck tare is assumed to be a constant. This of course will not be the case in the real world. Just the variation of the fuel remaining in the truck can cause the truck’s empty weight to vary 1000 lbs. We recommend using a full tank of fuel when measure the truck’s empty weight so this should always represent the highest possible weight of the truck.


44

INSTALL – Provides the capability to setup and change the operating configuration of LoadMan. When activated with “YES”, then the first installation option is displayed; “LOADCELLS 2”. Most cart lifters will have only 2 Loadcells but some models will have more. The available INSTALL options are shown in Table 7. These categories are

selected and activated using the /SELECT, /PROGRAM and SET

PROGRAM keys.

The COUNT BY rounding can be momentarily disabled on the display by continually depressing the SELECT key that is used to manually select a particular weight display. LoadMan will display the weight count in increments of 1 as long as the SELECT key is continuously depressed. Releasing the SELECT key causes the display to return to the programmed COUNT BY resolution.

o ACCOUNTS – Load Manager Software will automatically load the number of route account names and numbers that have been downloaded into LoadMan’s memory. This number is automatically set when LoadMan Load Manager Software downloads ACCOUNTS but can be overridden with this command (programming to zero will remove all accounts).


48

Regarding Account Load Names, Account Numbers, Products and Events:

LoadMan allows up to 940 different Load Names & corresponding Account Numbers, 50 unique Product Names, 50 Events and 250 different Assets to be captured upon each recording of a load - “RECORDING LOAD”. These account names, products, events, and assets can be downloaded to the meter with LoadMan’s Load Manager

Software.

o PRODUCTS – Configures the number of route product names that can be displayed (default is 0, max is 50). This number is automatically set when LoadMan Load Manager downloads PRODUCTS but can be overridden manually.

o EVENTS – Configures the number of route events that can be

displayed (default is 0, max is 50). This number is automatically set when LoadMan Load Manager downloads EVENTS but can be overridden manually. Example EVENTS are ROAD CLOSED, GATE LOCKED, NO BIN AVAILABLE, etc.

o ASSETS – Configures the number of route assets that can be

displayed (default is 0, max is 250). This number is automatically set when LoadMan Load Manager downloads ASSETS, but can be overridden manually.

o TARGET SETPT– Turns on or off the TARGET weight display. When

turned on, this display allows the operator to set a target overload set point that will activate a hardware alarm and/or will trigger a LoadMan display when the target net weight of the truck has been exceeded. Especially useful for tracking and detecting the current gross weight of the truck; avoiding overloads and fines.

o FLASH LDNAME – When this display is activated to “YES”, the currently active Load Name will be flashed every few seconds on the weight display, aiding the operator to identify the current account that will be saved when a load is recorded as an aid to easily identify the active account.


49

o FLASH ACCT# – When this display is activated to “YES”, the

currently active ACCOUNT# will be flashed every few seconds on the weight display, aiding the operator to identify the current account that will be saved when a load is recorded.

o FLASH STOP# – When this display is activated to “YES”, the currently active STOP# will be flashed every few seconds on the weight display, allowing the operator to identify the current account stop number that will be saved when a load is recorded

o FLASH PRODUCT – When this display is activated to “YES”, the currently active PRODUCT (refuse, recycling, cardboard, etc.) will be displayed. When enabled, and to choose a product name: Locate the PRODUCT display using the /SELECT keys, Locate the particular product name using the /PROGRAM

keys,


When the load is recorded, the product name will be recorded into LoadMan’s data collection memory along with the account name, account number, and any other enabled route options.

Once a product name has been selected, it will remain in effect for all subsequent load recordings. The product name should be re-programmed whenever the product condition changes.

o FLASH EVENT – When this display is activated to “YES”, the

currently active EVENT will be displayed. When enabled, and to choose a problem condition: Locate the current EVENT condition display using the

/SELECT keys, Locate the particular problem condition using the

/PROGRAM keys,

Activate the problem condition with the PROGRAM key. SET

When a load is recorded, the event condition will be recorded into LoadMan’s data collection memory along with the account name,


50

account number and any other enabled route options.

Once an EVENT condition has been selected and recorded with the RECORD command, it will revert back to the NO EVENT condition for all subsequent load recordings. New event conditions should be re-programmed anytime a route event/problem is encountered and before the next load is recorded.

o FLASH OVERLD – When activated to “YES”, LoadMan will place a

message on the display (and activate an optional hardware alarm) anytime the TARGET weight has been exceeded. In the normal operating mode the message, “GROSS >>> TARGET” will display anytime a load exceeds the target weight. Especially useful for tracking and detecting the current gross weight of the truck; avoiding overloads and fines.

o GEO ROUTE – Route information will be downloaded from

LoadMan Load Manager Software when set to “YES”. The GEO ROUTE feature can then be selected as the active Operating Mode using PROGRAM FUNCTION display in the normal operating mode. Geo Route, also known a proximity routing, allows LoadMan to determine whether route pickups are located within a proximity of 300 to 1000 feet (programmable). If only one customer name is indicated on the 16 character display, then the driver can simply lift the load as instructed on the display. If more than one customer account is displayed, then LoadMan has detected other customers with the proximity of the truck. The driver must choose the correct customer in order to report the correct weight with the correct customer account. Locate and choose the customer account using the /PROGRAM keys.

Activate the account with the PROGRAM key SET

SETUP MODEM – When set to “YES”, the command configures the

communications modem. The LoadMan meter may come equipped with an optional GSM cellular


51

modem. The modem is used to connect and communicate with LoadMan’s Load Manager Software. The Load Manager Software allows remote tracking of trucks, drivers, customers and routes, and exchanges the load and location information through this modem. o MODEM OPTION – Set this option to “YES” if the LoadMan meter

has been configured with a GSM modem board for remote communications. If the modem is not installed, make certain to choose the “NO” option.

o MODEM ---- country – Sets the country in which the cell modem will operate. The default configuration is USA. Choose USA or CANADA using the PROGRAM key,

Activate the country with the PROGRAM key. SET

International Modems - If the country is outside the USA and Canada, then the country should be left on USA. The meter has to be ordered with an International Option for this to work properly.

o CONN xxx SEC – Sets the time period (in seconds) between polling connection attempts between the LoadMan meter and the LoadMan Load Manager Software.

o RSET xxxx SEC – Sets the time period (in seconds) when the modem will reset if it has not been fully “exercised” within the xxx time window. The factory default is 3600 seconds (1 hour). If the RSET is executed, then the modem had probably been stuck in some state. RSET will toggle power to the modem and reset. This

value can be adjusted with the /PROGRAM and PROGRAM SET

keys.

o BAUD RATE>115200 – Indicates the baud rate of the modem. This number should always be set to 115200. If not, use

/PROGRAM and PROGRAM keys to correct the value. SET


52

o Remote IP – The remote IP address fields contain the IP address of

the LoadMan TCP relay that coordinates data communication between the vehicle and the LoadMan Load Management Software. When using a cellular data modem, these IP addresses must be set as documented:

RemoteIP1 74 RemoteIP2 93 RemoteIP3 98 RemoteIP4 177

If for any reason these LM310 values do match the values listed

here, then use the /PROGRAM and PROGRAM keys to SET

program, select and correct to the address fields as shown. .

SETUP GPS – When set to “YES”, this command programs the logging of

GPS coordinates. The LoadMan meter may come equipped with an optional internal GPS chip and antennae. LoadMan’s Load Manager Software uses onboard GPS capability to track and map truck, load and customer locations. o LOG xxx SEC – Programs the time period (xxx seconds) between

the logging of GPS coordinates into LoadMan’s data collection memory. The factory default setting is 30 seconds.

When recorded GPS coordinates are uploaded into LoadMan’s Load Manager Software, the software will be able to use the coordinates to map load locations, track truck routes and aid with several other advanced location based functions.

SET RECORD – Whenever a load is recorded using the RECORD LOAD command, LoadMan uses several record options to customize the way that the load data is displayed and recorded. Choose “YES” to program the following RECORD options:

o RECORD&PRINT – When set to “ON”, directs LoadMan to print the

recorded load data to the RS232 port(s) as it is recorded into LoadMan’s data collection memory. If set to “OFF”, the load data


53

will be recorded to LoadMan’s data collection memory, but will not be printed.

Figure 7. Printed Load Ticket

o INCR STOP # -- When set to “ON”, LoadMan will automatically

increment and select the next stop number (and associated account information) from the downloaded route list after a load has been recorded. If no Route has been downloaded then the STOP # will simply increment on every load pickup.

o CONTsp xxxxx LB – Container set point. LoadMan provides this

capability to prevent the recording of load data records when there is no cart on the cart lifter. When programmed to a positive number, and if the gross weight measured going up is less than this set point value, then the weight will NOT be recorded as a load data record when the load comes back down. If programmed to zero then every lift will be recorded regardless of the gross cart weight measured going up.

SETUP RS232 – Configures LoadMan’s RS232 ports. LoadMan comes standard with one 9-pin RS232 port that can connect to peripherals like printers for printing load and route information, or to large scoreboard displays mounted on the truck to display weight information. Also, the RS232 port can connect to input devices like barcode readers for reading account and route information. Optionally, the LoadMan meter comes with a second RS232 port configured with either another 9-pin connector or with a Bluetooth antenna. Here are the three possible RS232 port configurations:


54

beginning with BAUD RATE.

Repeat this process for the second port by choosing “RS232 PORT #2?”

and pressing the PROGRAM key. Then configure the remaining port SET

#2 settings as described below – beginning with BAUD RATE. For Option 2, two port configurations (one Bluetooth port and one 9-pin port):

o For the first port, choose “RS232 PORT #1?” by pressing the SET

PROGRAM key. o “BLUETOOTH --->” should be set to “ON”.

For the second port, choose “RS232 PORT #2?” by pressing the SET

PROGRAM key. Then configure the remaining port #2 settings as described below – beginning with BAUD RATE.


55

o BAUD RATE – Programs the baud rate for the RS232 ports. The baud rate must match the baud rate of the peripheral device that will be connected to the port for LoadMan to properly communicate. The available baud rates are: 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 baud (factory default is 9600 baud).

When the LoadMan meter is equipped with the Bluetooth Option, then the baud rate for port #1 MUST be set at 9600 baud.

The following options are available only for RS232 9-pin ports:

o TICKET PRINT ON – Programs the RS232 port for printing to a serial printer mounted in the truck cab. Every time a cart is lifted and weighed, it will print the contents of the load data measured when the meter is showing RECORDING LOAD (If the Record and Print Option is set to YES in SET RECORD options). Other print options can be enabled with the print (PRT) commands described below.

o SCOREBOARD ON – When the SCOREBOARD is set to “ON”, then the total weight will be displayed to the truck’s scoreboard that’s connected to the RS232 port. It will always show the last measured load and other print options chosen with the SET RECORD/PRT commands.

o BARCODE – LoadMan supports automatic reading of account information with a bar code reader/wand. When set to “ON”, LoadMan configures the RS232 port to read from a barcode reader.

The following print options may also be offered for configuration, depending on which type of output device was selected (choose “YES” to activate any desired option). o PRT LOADNAME –Prints the active load account name. o PRT ACCOUNT – Prints the active load account number. o PRINT STOP# – Prints the active stop number.


56

o PRT PRODUCT – Prints the active product name. o PRT EVENT – Prints the active event condition.

o PRINT TRUCKg – Prints the truck’s gross weight. That is, the tare

weight plus the accumulated recorded load weights.

o PRINT CONTg – Prints the total gross weight of the container and

its load as the arms are raised.

o PRINT CONT – Prints the empty container weight (the container tare weight) as the arms are lowered.

o PRINT RFID – Prints the RFID tag read from the loaded container.

o PRINT ASSET – Prints the ASSET number of the container.

o PRT TRACE – Ignore. Used for factory service.

o COUNTBY – When ENABLED, the printed loads will reflect step (resolution) value that was configured in the SET DISPLAY/COUNTBY command. When DISABLED the printed loads will use the actual load weights measured instead of being rounded to the nearest COUNTBY Setting programmed for the LM310 display.

o LINE FEEDS xx – Programs the number of line feeds after every

PRINT TICKET printout (default is 2; 1 min; 10 max).

SERIALnum – Displays the serial number of the LoadMan meter. The serial number programmed into the meter is only needed when the LoadMan Load Manager data collection software features are used. Whenever data is uploaded to the LoadMan Load Manager Software, LoadMan will add the serial number to every load data record. This feature is especially useful when maintaining records for a fleet of trucks and is used to identify which truck the meter is in.


57

SECURITY – When set to “ON”, LoadMan will prompt for a valid

passcode whenever the LM310 meter is placed into SETUP and CONFIGURATION Mode. When prompted, enter passcode “123”.

At this point, LoadMan has completed the INSTALL portion of the Setup and Calibration Mode and will continue with the remaining Setup & Calibration options (SET DEFAULTS, ERASE DATA and TROUBLESHOOTING).

SET DEFAULTS – Reset the LM310 to the factory default settings. See Table 10. LM310 Factory Defaults below for a listing of the factory default settings. Use the PROGRAM key to choose either “DEFAULTS FOR LB?” or

“DEFAULTS FOR KG?” and press the PROGRAM key to activate. SET

Thereafter, the value is incremented every time a GPS record is stored in LoadMan’s data collection memory.

TRB LOAD RECORDS – Displays the number of load records contained in LoadMan’s data collection memory (RECORDS xxxxxx). When the ERASE DATA function is executed or after the LoadMan Load Manager


62

Software collects all the load data, this number is reset to zero. Thereafter, the value is incremented every time a load data record is stored in LoadMan’s data collection memory. (A second value, ERASE CTR-xxxxxx, signifying the number of times data has been erased, is provided for factory troubleshooting.)

TROUBLE POSITION – Choose this troubleshooting option to examine individual arm sensor settings and readings. o WGH START – Displays the starting set point angle of the weigh-in-

motion window. (Factory setting is 0.0 degrees.) o WGH END – Displays the ending set point angle of the weigh-in-

motion window. (Factory setting is 75.0 degrees.) o WGH DUMP – Displays the dump load set point angle of the weigh-

in-motion window. (Factory setting is 100.0 degrees).

With most cart tippers these weighing window settings should work correctly. However, there will be some carts/bins that may come in sizes that require different weighing window settings. Use these three programming settings to adjust to cart as necessary. Custom Adjustment of Weigh-In-Motion Window The default weigh-in-motion angle assignments were derived from the experience LoadMan gained working with customers and learning the most common sized carts used. However, there are carts that might

not “fit” the weigh window of 0, 75 and 100. Especially larger carts that are taller than the cart tipper and scale. For these larger carts, you will most likely need to adjust the weigh window. Here are some guidelines: Set the WEIGHT START angle where the cart is off the ground 6” to

12”. This might be from 5 to 15.

The WEIGHT END should never be higher than 75. When necessary, the WEIGH END can be set lower so that the cart

does not start dumping the load before the weigh window has been completed.

WEIGH DUMP needs to be at least 10 to 25 above the WEIGH END set point.


63

The weighing window angle set point settings can be programmed using

the / and PROGRAM keys. SET

o ARM DIRECTION = +/- This display should be used if the arm angle

does not increase in value when the arms are raised. If the arm angle decreases when the arms are raised, then the ARM DIRECTION sign should be reversed.

o ARMS xxx.x DEG – Displays the currently measured arm angle in degrees.

o ARM ZERO – The arm’s zero degree calibration constant set when the arms are zeroed.

o ArmSTRTup –First cart arm angle measured after passing WGH

START angle programmed going up.

o ArmENDup – Last cart arm angle measured prior to passing the end of weigh-in-motion window with the cart going up.

o ARMENDdn – First cart arm angle measured after passing the end

of weigh-in-motion set point WGH END with the cart going down.

o ArmSTRTdn – Last cart arm angle measured prior to passing the WGH START set point weigh-in-motion window while the cart is going down.

o Trace – (Service use only) o TraceLst – (Service use only)

TROUBLE CAL – Provides zero and span information to assist with troubleshooting and calibration of the weight sensors. o ZEROUpCAL – A zero calibration adjustment for weights measured

as the cart arm is raised. Normally this is zero but if going up there is a persistent zero error, then you can program a constant zero


64

offset that will be added to every measurement going up.

o ZERODnCAL – A zero calibration adjustment for weights measured as the cart arm is lowered. Normally this is zero but if coming down there is a persistent zero error, then you can program a constant zero offset here that will be added to every measurement coming down.

o SPANUpCAL – The SPAN calibration adjustment for weights measured as the arm is raised. Raising this number 10% will cause the scale to read 10% more going up.

o SPANDnCAL – The span calibration adjustment for weights measured as the arm is lowered. Raising this number 10% will cause the scale to read 10% more coming down.

o SampDevUp – 500 is recommended. This is a setting to weed out spikes in the weigh-in-motion cycle going up.

o SampDevDn – 500 is recommended. This is a setting to weed out spikes in the weigh-in-motion cycle coming down.

Initial Startup and Calibration Procedures

65

INITIAL STARTUP AND CALIBRATION The instructions in this section provide a step-by-step process for verifying and calibrating a newly installed LoadMan Cart Lifter Weigh-In-Motion system. Follow these steps to insure proper installation and operation. 1. Verify Wiring 2. Power On 3. Verify Arm Angle Sensor 4. Calibrate Arm Angle 5. Verify Arm Angle Measurements

respond correctly

6. Verify Weigh-In-Motion Response 7. Calibrate System for ZERO CART

Load 8. Calibrate System Under Load 9. Fine Tune Span Adjust

1. Verify Wiring

Begin by verifying that the electronics are wired per the wiring diagram shown in Figure 8 near the end of this manual. Positive 10VDC to 28VDC should connect to the LoadMan 310 Meter at

pins 1 and 2 to power the system. Verify connection of the cable harness from the LoadMan meter to the cart

lifter weigh-in-motion assembly. Then verify the connection of the cable harness from the cart weigh-in-

motion assembly to the arm weigh-in-motion assembly. Finally, verify that the cart lifter loadcells are connected to the cart lifter

weigh-in-motion assembly.

2. Power On

With power off, briefly press the front panel POWER button. LoadMan will power on and sign on with the display messages “LOADMAN”, followed by “PROG VERSION X.X” (where X.X is the software version). LoadMan will then confirm that the weigh-in-motion equipment is ready for operation with message, “READY TO WEIGH!”.


66

When power is applied, the message “CYCLE ARMS” may appear if the cart lifter is not in the READY TO WEIGH position. Repositioning the cart lifter arm to the normal Ready to Weigh position will return the display to “READY TO WEIGH”.

3. Verify Arm Angle Sensor

To verify the Arm Angle sensor is responding correctly, first enter the Setup & Calibration Mode as described earlier and use the SELECT key to locate the TROUBLESHOOT display. Weigh-In-Motion Window Press the PROGRAM key two times to locate the TROUBLE POSITION

option and press the key to activate. “WGH START 00.0” should display SET

on the meter display. WGH START is the programmable angular set point where the weigh-in-motion window starts the weighing of each load.

If it isn’t programmed to 00.0, use the PROGRAM keys to reset the

angle to 00.0 and press to activate the value. SET

Press the SELECT key to display “WGH END 75.0”. WGH END is the programmable angular set point where the weigh-in-motion window ends the weighing of each load.

If it is not programmed to 75.0, use the PROGRAM keys to reset the

angle to 75.0 and press to activate the value. SET


67

Press the SELECT key to display “WGH DUMP 100.0”. WGH DUMP is the

programmable angular set point where LoadMan “stores” the recording of the net load weight.

If it is not programmed to 100.0, use the PROGRAM keys to reset the

angle to 100.0 and press to activate the value SET

Custom Adjustment of Weigh-In-Motion Window The default weigh-in-motion angle assignments were derived from the experience LoadMan gained working with customers and learning the most common sized carts used. However, there are carts that might not “fit” the

weigh window of 0, 75 and 100; especially larger carts which are taller than the cart tipper and scale. For these larger carts, you will most likely need to adjust the weigh window. Here are some guidelines: Set the WEIGH START angle where the cart is off the ground 6” to 12”. This

might be from 5 to 15.

The WEIGH END should never be higher than 75. When necessary, the WEIGH END can be set lower so that the cart does not

start dumping the load before the weigh window has been completed.

WEIGH DUMP needs to be at least 10 to 25 above the WEIGH END set point.

4. Verify Cart Lifter Load Cells Respond Correctly

To verify the loadcells are responding correctly, first enter the Setup & Calibration Mode and use the SELECT key to locate the TROUBLESHOOT

display.

Press the PROGRAM key to locate the TROUBLE LOADCELL option and press the key to activate. SET


68

The message, “CH1 SPAN 400,000” should be displayed. This is the normal sensitivity used for the CH1 left cart lifter loadcell and should not be changed.

SELECT till you get to CH2 SPAN which should also display 400,000. If either of these values is incorrect, use the PROGRAM keys to reset

either SPAN and press to activate the value. SET

Press SELECT to display “CH1 xxxx.x LB” where xxxxx.x is the current

weight reading of the CH1 loadcell. It is calibrated in LBs or KGs. Move the cart lifter arms so that the cart lifter plates are in the vertical

position and verify the CH1 and CH2 loadcells are reading near 0 lbs. Hang a load on the cart lifter or push on it and both CH1 and CH2 loadcells

should go positive. If not, then you need to swap the CH1 and CH2 loadcell connectors on the Cart 310 Electronics Box.

5. Calibrate Cart Lifter Arm Angle

If not already done, begin this procedure by first cycling the arms until the message “READY TO WEIGH” is displayed.

Enter the Setup & Calibration Mode. Press the SELECT key until “SET ZERO?--->NO” is displayed. Press the PROGRAM key until “ZERO ARM ANGLE?” is displayed and then

press to activate. SET

The display now shows several sequential messages; “THIS IMPACTS YOUR

CALIBRATION” and “PROCEED?---->NO”.

Use the PROGRAM key to choose “YES”, and activate with the key. SET

LoadMan displays, “POSITION ARMS TO ZERO ARM ANG” and “READY?----->NO”.

Move the cart lifter arms till the cart lifter mounting plates are perfectly vertical (recommend using a level for this step), to set the arm angle sensor to read zero at this position.


69

Once the arms are in position, use the PROGRAM key to choose “YES”,

and activate with the key. SET

LoadMan displays, “ZEROING ARM ANG!” while it is reprogramming the start position of the weigh-in-motion window; and is finished “ZERO COMPLETE” is displayed.

To verify this process worked correctly, enter the TROUBLE POSITION portion of the TROUBLESHOOT display: Now verify that the “ARMS xxxxx.x DEG” reads very near zero degrees when

the cart lifter mounting plates are perfectly vertical. Furthermore, the arm angle (ARMS) should become more positive when

the arms are raised higher. If the arm angle reads negative (-) as the arms are raised, you will be able

to correct this error in Step 6.

6. Verify Angle Measurements Respond Correctly

Verify Cart Lifter Arm Angle Response Enter the TROUBLE POSITION portion of the TROUBLESHOOT display. Press the SELECT key until the display reads, “ARMS xxxx.x DEG”. Lift a cart from the ground until the arm angle reads 0.0 degrees. The cart

lifter mounting plates should be perfectly vertical when the arm angle reads zero degrees. Also, the arm angle should increase as the arms are raised and decrease as the arms are lowered. If so, ten proceed to Step 7.

If the direction is wrong, toggle the arm direction sign: ARM DIRECTION = +/- This display should be used if the arm angle

does not increase in value when the arms are raised. If the arm angle decreases when the arms are raised, then the ARM DIRECTION sign should be reversed by using the PROGRAM key to choose “YES”, and

activate with the key. SET

7. Verify Weigh-In-Motion Response

To verify the weigh-in-motion response, first exit the Setup & Calibration Mode: Use the SELECT key and choose the display, “EXIT SETUP?-->NO”.

Use the PROGRAM key to change “NO” to “YES” and press to activate. SET

LoadMan should now be in the Normal Operating Mode. The display should now read, “READY TO WEIGH!”.


70

Raise the cart tipper up through a complete weighing cycle. If everything is working properly the system should respond with the following: o WEIGHING LOAD! while the arms are in the weigh-in-motion weighing

window. o GROSS xxxxx LB as the arms pass the end of the weigh-in-motion

window. o DUMP xxxxx LB and LOAD xxxxx LB (alternating) when the arms pass up

through the dump set point. This message indicates that the record load data and auto accumulator functions have been activated.

Now lower the cart tipper and the display should show: o LOWER ARMS while passing down through the dump set point. o WEIGHING TARE as the arms pass down through the weighing window. o 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.

o RECORDING WEIGHT! – indicates that the weighing process is complete and the load has been recorded.

In a few seconds LoadMan will indicate that it is ready for the next load with the message, “READY TO WEIGH!”.

If all of this has worked correctly, proceed to the next step. If not, return to step 3, ”Verify Angle Sensors are Responding Correctly”, and redo the process until all is performing correctly.

Fine Tuning Loadcell Accuracy – LEARN ZERO

LEARN ZERO? – Learn Zero is the process of “custom learning” the zero response of the cart tipper’s loadcells; fine tuning the accuracy of each loadcell. This is accomplished by a series of lifts (12-15 lifts are recommended). Without this procedure the loadcell measurements could be inaccurate and misleading. The process is quite simple. Just follow the LoadMan display instructions:

Activate with the PROGRAM key. SET

REMOVE CART! – Remove the cart for the entire LEARNING process. RAISE ARMS! LEARNING ZERO UP LOWER ARMS! LEARNING ZERO DN CYCLES – Displays the number of LEARN cycles completed.


71

The above process should be repeated from 12-15 times to allow LoadMan to fully determine each loadcell’s zero response; fine tuning the accuracy of each loadcell. When finished repeating this process, simply let the cart lifter rest at zero. LoadMan will provide screen instructions to complete the LEARN process: UPSELECT IF DONE - SELECT. SAVE ZERO? – Use the PROGRAM programming key to choose “YES”, and

confirm with the PROGRAM key. SET

SAVING ZERO DATA – Wait for LoadMan to process before activating any further keys.

8. Calibrate System Under Load

LEARN SPAN? – Learn Span is the process of “custom learning” the calibration of the cart tipper’s loadcells. This is accomplished by a series of lifts (12-15 lifts are recommended). Without this procedure the loadcell measurements could be inaccurate and misleading. The process is quite simple. Just follow the LoadMan display instructions:

Activate LEARN SPAN with the PROGRAM key. SET

ENTER SPAN CAL (Factory default is 400LB). Press SELECT key to continue. ENTER CAL LOAD – This is the calibrated weight of a cart loaded with a

known scale weight from another calibrated scale. This load should be tightly secured within the cart for safety, and to make certain there is no abrupt bouncing of the container’s contents during the calibration procedure.

Use the /PROGRAM programming keys to enter the weight reading

obtained from the calibrated scale. Press the PROGRAM key to save, SET

and press SELECT key to continue.

LoadMan will respond with LOAD CAL WEIGHT! and has initiated the LEARN SPAN calibration process:

RAISE ARMS! LEARNING SPAN UP LOWER ARMS! LEARNING SPAN DN


72

CYCLES – Displays the number of LEARN cycles completed. The above process should be repeated from 12-15 times to allow LoadMan to fully determine each loadcell’s span; fine tuning the calibration of each loadcell. When finished repeating this process 12 to 15 times, simply let the cart lifter rest at zero. LoadMan will provide screen instructions to complete the LEARN process: UPSELECT IF DONE - SELECT. SAVE SPAN? – Use the PROGRAM programming key to choose “YES”, and

confirm with the PROGRAM key. SET

SAVING SPAN DATA – Wait for LoadMan to process before activating any further keys…this may take few moments.

Calibrate System for ZERO CART LIFTER LOAD

Begin this step by entering the INSTALL section of the Setup & Calibration Mode and program the LoadMan meter to “SHOW NEGATIVE WEIGHTS” by choosing “YES”. (Later, after completing this calibration, the meter can be reprogrammed to hide negative net weights if desired.)

In order to obtain the most accurate calibration results, advance forward to the INSTALL/SET DISPLAYS section and set the COUNT BY value to one (1);

using the PROGRAM key to choose “1”, and activate with the key. SET

Remove any cart off the cart lifter, EXIT SETUP, and return to normal operating mode.

With LoadMan showing READY TO WEIGH, press the SELECT key to find the PROGRAM FUNCTION display. Press the PROGRAM key to locate the

ZERO CART LOAD display; press to activate; and follow this procedure: SET

o LoadMan starts this process with the messages “REMOVE CART LOAD” and “SET ARM ANGLE = 0”.

o Position the cart lifter arms until the arm angle is within a degree of zero. LoadMan will provide instant feedback on the current Arm± angle. When the arm angle is within a degree of zero for a couple moments, LoadMan stops providing ± angle feedback and displays ZERO COMPLETE – indicating the process completed successfully.

o Try a few lifts with no cart on the cart lifter and you should read zero going up and zero coming down or very close to that.


73

Calibrate System for ZERO CART LIFTER LOAD Switch

LoadMan also features a ZERO CART LOAD switch that is mounted on the left outside plate of the cart lifter scales. This light/switch allows the operator to work at the rear of the truck, reading the green strobe light while leveling the cart arm angle to zero.

Depressing this switch initiates the zero load process that was just described above. And it also features a green light strobe that provides real-time feedback on the cart angle. The closer the angle to zero, the faster the light flashes. And when the fork angle is between 0 and +/-1, the light will hold steady.

When finished, the light provides a high frequency “chattering” strobe indicated that the Zero Weight is calibrated accurately. When finished, depress the switch

to turn off the light and the zeroing process.

Calibrate Cart Lifter Gross “Going Up”

Verify that the cart lifter load measured going up is calibrated to zero. Begin this process in the READY TO WEIGH state. With no load on the cart lifter, slowly raise the cart lifter arms through the

weighing window to verify if the GROSS xxxxx LB measurement going up is zero.

Perform several slow lifts going up to find an average gross weight. If zero, then skip this next calibration step.

If the average gross weight going up is not zero, the meter should be fine-tuned to allow for the variance from zero. o Go to the TROUBLESHOOT section of the Setup & Calibration Mode and

choose the section titled TROUBLE CAL.

This calibration adjustment will ALWAYS be listed in pounds even when LoadMan is using KG in the normal operating mode.

o Fine tune the ZEROUpCAL setting to account for the average gross


74

weight variance. For example, if the average gross weight is +10 LB going up, then increase the ZEROUpCAL by 10 counts from the current setting. (In KG mode, change the count 2.2X larger than the LB mode value displayed.) For this example program ZEROUpCAL to 10 using the PROGRAM

keys, and activate with the key. SET

o After programming the adjustment EXIT SETUP; return to the READY TO

WEIGH state. o Verify that the GROSS xxxxx LB averages zero (0) over several slow test

weights. Repeat this process until an average reading of zero is measured.

Calibrate Cart Lifter Net “Going Down”

After LoadMan returns to the READY TO WEIGH display, verify if the arm load going down is calibrated to zero: With no load on the cart lifter, slowly raise, and then very slowly lower the

arms through the weigh-in-motion window to verify if the NET xxxxx LB measurement going down is zero.

Do several measurements going down to find an average net weight. If zero, then skip this next calibration step.

If the average net weight going down is not zero, the meter should be fine-tuned to allow for the variance from zero. o Go to the TROUBLESHOOT section of the Setup & Calibration Mode and

choose the section titled TROUBLE CAL.

This calibration adjustment will ALWAYS be listed in pounds even when LoadMan is using KG in the normal operating mode.

o Fine tune the ZERODnCAL setting to account for the average net weight

variance. For example, if the average net weight is +10 LB going down, then adjust the ZERODnCAL 10 counts from the current setting. (In KG mode, change the count 2.2X larger than the LB mode.) For this example, program ZERODnCAL to 10 (ten) 10 using the

PROGRAM keys, and activate with the key. SET

o After programming the adjustment, EXIT SETUP; and return to the


75

READY TO WEIGH state. o Verify that the NET xxxxx LB averages zero (0) over several slow test

weights.

9. Fine Tune Span Adjust

This step requires a loaded cart with a known weight; so have a cart weighed on a known accurate scale. The cart should be loaded with a good size weight that represents at least 80% of the cart lifter’s capacity. This load should be tightly secured within the cart for safety, and to make certain there is no abrupt bouncing of the container’s contents during the calibration procedure. When LoadMan is READY TO WEIGH, pick up the loaded container and

move through the weigh-in-motion window at a slow speed. Do this several times to obtain the average GROSS xxxxx LB reading going up and note this average gross weight reading.

Next, perform a span truck calibration process. o Use the PROGRAM key to select “SPAN TRUCK?” and activate with the

PROGRAM key. SET

o LoadMan responds with directions to “ENTER METER LOAD”. o Use the programming keys to enter the average of weight readings that

were just obtained from the LoadMan meter. Press the PROGRAM SET

key to save. o Press the SELECT key and LoadMan will respond with the directions,

“ENTER CAL LOAD”. o Use the programming keys to enter the weight reading obtained from

the calibrated scale. Press the PROGRAM key to save. SET

o Now press the SELECT key and LoadMan will respond with the directions, “DO AUTOCAL?-->NO”. This display is confirming that the weights have been entered properly.

o To confirm that the weight entries are correct, select “YES” and press

. SET

o LoadMan will now complete the SPAN calibration and confirm with, “DOING SPAN ADJUST” and “SPAN COMPLETE!”.

o EXIT SETUP and return to the READY TO WEIGH state.

At the READY TO WEIGH state, slowly pick up an empty container and move up through the weigh-in-motion window.


76

Lower the container down through the weigh-in-motion window at the slowest speed. Do this several times to obtain an average NET xxxxx LB reading going down.

If the NET reading is not zero (0) then use to the TROUBLE CAL section of the TROUBLESHOOT Setup & Calibration category to either increase or decrease the SPANDnCAL value to correct the error using the ratio calculation:

Ratio = Gross Weight Going Up ÷ (Gross Weight Up – Net Weight Down)

For example, if the average “going down” NET weight reading is +20 LB and the average “going up” GROSS reading was 720 LB, then the system going down is measuring only 720-20 = 700 LB. So the SPANDnCAL value needs to

be adjusted by the ratio: 720÷700 = 1.02857

Reprogram SPANDnCAL by multiplying the current SPANDnCAL value times(x) the weight ratio. Then EXIT SETUP.

Continue this calibration process until the weights going up and going down are equal, and the empty cart NET xxxxx LB reading is zero (0).

Once this calibration procedure is completed, the SPANUpCAL and the SPANDnCAL values may not be equal, but they should not be different by more than 500 counts for a system that is operating properly.

REMINDER – During these calibration procedures, COUNT BY was programmed to 1 and SHOW NEGATIVE WTS was set to YES. Reprogram either or both these values (if desired) for the normal operating of the weighing system.

Troubleshooting Guide

77

TROUBLESHOOTING GUIDE This section of the manual provides a guide to troubleshooting common issues with the LoadMan Cart Lifter Weigh-In-Motion System. It is assumed that the reader has already become familiar with using the programming keys and understands how to access Setup & Calibration functions that are all detailed in the chapter titled Setup & Calibration Mode. LoadMan must receive all sensor signals in order to display the valid weighing display message “READY TO WEIGH”. The four sensor signals are:

Left Cart Loadcell Signal

Right Cart Loadcell Signal

Cart Arm Angle Sensor Signal If any of these signals are not detected, then LoadMan suspends all weighing functions and enters into a Troubleshooting Diagnostic Mode. When LoadMan enters this mode, one to three diagnostic messages will be displayed:

NO ARM SENSOR! or ARM SENSOR OK!

NO RGHTCART SIG! or RGHTCART SIG OK!

NO LEFTCART SIG! or LEFTCART SIG OK!

1. NO ARM SENSOR! This message is displayed when there is no communication to the arm weigh-in-motion sensor. The arm weigh-in-motion assembly (ARM310) contains a microcomputer and arm angle sensor. The microcomputer communicates the cart lifter arm angle measurement to the LoadMan CART310 box mounted between the cart lifter plates. The CART310 sends all the results to the in-cab meter for processing and display. If LoadMan cannot detect the arm assembly microcomputer, then there are three possible sources to the problem:


78

a) The cable connection from the CART310 Box to the arm weigh-in-motion assembly box has failed or is not connected.

b) The arm weigh-in-motion assembly has failed. This unit is a potted assembly to survive harsh outdoor environments. The unit is not field-repairable and must be replaced or rebuilt.

c) The LoadMan meter has failed. The meter is not a field-repairable for

this type of communication failure. It must be replaced with a new or rebuilt unit.

2. NO LEFTCART SIG! and NO RGHTCART SIG! If these two messages are displayed, first make certain that the cable connecting the LM310 Loadman Meter is properly connected to the CART 310 Box mounted between the cart lifter plates.

a) The CART310 weigh-in-motion assembly contains the digital to analog converters for both the right and left cart lifter loadcells and receives the cart lifter arm angle from the arm sensor box (ARM310) mounted on the cart lifter arms. Check the cable that connects the LoadMan meter (LM310) to the CART310 box mounted between the cart lifter mounting plates.

b) If the cables are connected securely, then check the cable harness for damage and perform a continuity check.

c) If the cable is OK but the messages NO LEFTCART SIG! and NO

RGHTCART SIG! still display: o Attempt to disconnect both loadcell cables that plugged into the

CART310 weigh-in-motion box to eliminate a fault in one or both of the loadcells.

o If after unplugging both loadcells the messages NO LEFTCART SIG! and NO RGHTCART SIG! still displays, then the CART310 weigh-in-motion box has most likely failed or the LoadMan Meter (LM310).

o The CART310 weigh-in-motion module is a potted assembly to survive harsh outdoor environments. The unit is not field-repairable and must be replaced or rebuilt.


79

3. NO LEFTCART SIG! but RGHTCART SIG OK! LEFTCART SIG OK! but NO RGHTCART SIG If one of the loadcell signals is present but the other is not, then it is most likely that one of the loadcells has failed. Swap the two loadcells on the weigh-in-motion assembly and see if the error message reverses. If it does, then one of the loadcells has failed. Swap the loadcells again to make certain which loadcell has failed. When isolated, replace the failed loadcell.

4. Load Measurements 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 CART310 digital to analog converter (CanCoder) has failed.

Cart arm angle measurements are faulty. Check Loadcell Response and CART310 CanCoder Press the PROGRAM key to locate the TROUBLE LOADCELL option and

press the key to activate. SET

Press SELECT to display “CH1 xxxx.x LB” where xxxxx.x is the current weight reading of the CH1 loadcell.

Move the cart lifter to zero arm angle, which will cause the plates to be in a vertical position. The CH1 load should read near zero (0) weight

Pick up an empty container and verify that the loadcell responds in a positive direction. o If the loadcell responds in a negative direction under load, then swap

the loadcell connectors on the CART310 Box as they are connected to the wrong loadcell connectors.

o If the loadcell reading is bouncing hundreds (100’s) of counts, drifting, or will not repeat the same reading under a given container load, then: either the loadcell has failed; or the cart lifter CART310 weigh-in-motion analog to digital

converter has failed; or a loadcell cable has been damaged; or the connector is loose and has moisture/dirt in the contacts.

Check for damaged loadcell cables or dirty contacts. If the contacts are dirty then the pins should be cleaned with isopropyl alcohol and a Q-tip. The signals on these pins are on the order of less than one millionth of a


80

volt so any film residue or moisture on the contacts can cause the loadcell signals to drift wildly. If the problem persists after cleaning the contacts then the Cart310 CanCoder weigh-in-motion box should be replaced. If replacing the Cart310 weigh-in-motion box does not fix the problem then the loadcells should be replaced.

Press SELECT to display the message, “CH2 xxxx.x LB” and repeat the above procedure for the CH2 loadcell.

Checking Cart Lifter Arm Angle Measurements

LoadMan relies heavily on the accuracy of the cart lIfter arm angle measurement to determine accurate weight measurement results. The loadcell weight measurement response is influenced by the cart lifter arm angle. Any error in the arm angle will have a major effect on the overall accuracy of the weighing system. Furthermore, the arm angle informs LoadMan when to look at the cart lifter 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 on the arm angle calibration: While still in the TROUBLE POSITION option of the TROUBLESHOOT Setup &

Calibration category, view the current arm angle, “ARMS xxxx.x DEG”. The arm angle should read zero degrees when the cart lifter has lifted the

cart off the ground near a foot. If not, then got to step 5 of the Initial Startup and Calibration Procedures

and follow the directions for calibrating the arm angle.

Collecting Load Data

81

COLLECTING LOAD DATA When a load is recorded, load data is stored into LoadMan’s data collection memory. The load information is recorded and stored as shown in Table 12.

Table 12. Recorded Load Data

Product Optional (INSTALL/DISPLAYS/PRODUCT)

Event Optional (INSTALL/DISPLAYS/EVENT)

GPS Coordinates If GPS modem and signal available

After each recording of a load, LoadMan sequences (when auto sequence enabled) to the next Stop Number and its corresponding Load Name and Account Number, and is therefore automatically set up for the next collection.

Out-of-Sequence or Unplanned Collections It may sometimes be necessary to collect a load out-of-sequence or to record a load that was unplanned during a collection route. There are several options available through the front panel PROGRAM buttons for these and similar situations.


82

Programming the STOP# Display If a printed copy of the route schedule is available, then the stop numbers will be listed for each stop on the route. Use the route schedule to find the stop number of the account that needs collected and recorded out-of-sequence. Then use the SELECT and PROGRAM front panel keys to select the new stop number before recording a load.

For example, LoadMan is currently displaying STOP #45, but instead, STOP #198 needs to be collected and recorded. Using the /SELECT keys, locate the STOP # display; then use the /PROGRAM keys to change #45 to #198. This will direct LoadMan to go directly to Stop #198 and the corresponding load name and account number for the stop.

If a stop number is entered that is not found in the route list (i.e., a stop number that is higher than any on the list) then LoadMan will display the highest stop number in the route list.

Programming the ACCOUNT # Display If the account number is known, use the SELECT and PROGRAM front panel keys

to enter the account number before recording the load. Then, when the SET

PROGRAM key is pressed, LoadMan will search the downloaded route list for the entered account number. If the account number is found in the downloaded route list, LoadMan will display/confirm with the associated stop number and account number.

If the account number is not found in the downloaded route list, then LoadMan automatically creates the new account and displays the message “CREATING

ACCOUNT”; followed by the display of a new stop number and the newly created account number. The new stop number will be added to the downloaded route list, along with the new account number, and a newly created load name “UNPLANNED STOP XX”; where XX represents the number of unplanned stops in memory. This new stop number, account number and load name will be added after the last stop in the currently downloaded route list. Selecting a Load Name Using the LOAD NAME Display To select a specific load name from the list of downloaded route load names, first use the /SELECT keys to locate the current LOAD NAME display. The PROGRAM key will sequentially display the next load name from the route list. A flashing curser will indicate that LoadMan has entered the Program Operating Mode. Pressing the PROGRAM key will sequence forward to the next load


83

name, while the PROGRAM key will sequence in reverse. Press the SET

PROGRAM key to select and load a displayed load name. Recording a Product Some companies will download routes that include specific product names for describing their pickup services (e.g., cardboard, recycles, garbage, yard clippings, etc.). To choose and record a product for the current Stop #:

PRODUCT displays must first be enabled with the SET DISPLAY/FLASH PRODUCT command.

Locate the PRODUCT display using the /SELECT keys. Locate the particular product name using the /PROGRAM keys.


When the load is recorded, the product name will be recorded into LoadMan’s data collection memory along with the stop #, account name, account number and any other enabled route options.

Once a product name has been selected, it will remain in effect for all subsequent load recordings. The product name should be re-programmed whenever the product condition changes.

Recording Unexpected Events Sometimes a problem/event will occur in the process of picking up or delivering a load and it is valuable to record that event for a particular route stop (e.g., no container, road blocked, gate locked, etc.). To choose and record an Event for the current Stop #:

EVENT displays must first be enabled with the SET DISPLAYS/FLASH EVENT command.

Locate the EVENT display using the /SELECT keys. Locate the particular problem/event name using the /PROGRAM keys.

Activate the event name with the PROGRAM key. SET

When the load is recorded, the event condition will be recorded into LoadMan’s data collection memory along with the stop #, account name, account number and any other enabled route options.

Once an Event condition has been selected and recorded, it will revert back to the NO EVENT condition for all subsequent load recordings. New event conditions should be re-programmed anytime an event is encountered and before a load is picked up and recorded.

Downloading LoadMan Meter Software

93

Appendix D – Downloading LoadMan Meter Software A circumstance could take place that might require an update to the LoadMan meter software that is running in the LM310 Meter, CART310 Box and/or the ARM310 Box.

Connecting PC/Laptop to LM310

Step1: Install LoadMan Load Management Software (LLM) LoadMan provides an unlicensed version of its software as a platform for connecting and programming the LoadMan electronics like the LM310 and the ARM310. A copy of this software can be obtained from an Authorized LoadMan Dealer. Territory dealers are listed on the LoadMan website: http://loadman.com/dealer-listing/.

Step 2: Connect Windows PC to LM310 Display There are two types of connectors to connect a Windows PC/Laptop to the LM310 display. A direct serial connect between a PC COM port and the LM310 port#1 serial

port. <or>

A wireless Bluetooth connection between a PC COM port and the LM310 Bluetooth port. A common device to repurpose a USB COM port to Bluetooth is the Parani SD100. For our

Figure 13. Parani SD100 USB to

Bluetooth

http://loadman.com/dealer-listing/


94

demonstration, we’ll use Bluetooth. Step 3: Identify the PC’s Serial Communications Port After the serial or Bluetooth connector has been attached to the PC, you must learn the exact COM port number that is being used by reviewing the Windows Device Manager Table. To access Device Manager, use any of the following (3) methods (depends on which Windows O/S you are using): Click Windows Start Button in lower left corner

o Click Run, o Then type devmgmt.msc

<or> Right-click My Computer (sometimes it’s simply Computer)

o Click Manage, o Then click Device Manager

<or> Right-click My Computer

o Click Properties, o Click the Hardware tab, o Then click Device Manager.


95

Within Device Manager, click and open-up “Ports (COM & LPT)”

Make sure and note the COM port listed.

(COM3 for this example).

Step 4: Configure COM Port in LoadMan Load Manager Software Now that the PC Serial COM Port has been identified, return to the LoadMan Load Manager Software to direct LLM to use this COM port for communicating to the LM310.


96

From LoadMan Load Manager o Click Tools o Click Connections

The “Add Connection” dialog is displayed with all the currently defined COM

ports available for LLM. We will be using the Bluetooth/Parani connections In our example Note that BLUETOOTH is currently configured to COM1. To change the configuration, click on Edit COM3 is not set-up/defined, so click the Add key to set-up and configure the COM3 port.


97

Shown here is the dialog box before setting-up any COM connection details.

In the Name Field, choose a name for the COM port – in our example, simply

call it “COM3:9600”. The 9600 indicates the baud rate on the port. Under Baud Rate click on 9600. Under Comm Port, click on COM3. Ignore the rest of the fields as these defaults work fine.

Enter OK when complete.


98

CLOSE the Connection table. View the added COM3 port in the LLM Communications Table.

Step 5: Connect LLM to LM310 Using Terminal Emulation Make certain that the host PC that’s running LoadMan Load Management

Software is connected to the LM310’s Port#1. Power on the LM310.


99

Initiate the Terminal Connect dialog with the LM310 o Make certain LM310 Bluetooth in turned ON o From the Load Manager click on Tools o Select Advanced Functions o Click on Connect Comm Port…

Choose COM port (in our example COM3:9600) and click OK.


100

When you can view this blank screen, click on Bluetooth Query….

…directing LLM to find the LM310 Bluetooth connection.


101

Now, highlight the query result and press connect

Press and hold “Ctrl” and “T” keys simultaneously, until you see the following

menu.

Note the Dnload button at the top of the display. By clicking this button, you will be asked for the file name to download to the LM310 to upgrade any currently stored software version. For downloading software for upgrading the CART310 Box or ARM310 Box, here is a YouTube video describing the procedure:
