CHAPTER 1 Description of LOADTRONIC 3

LOADTRONIC 3 is an automatic and dynamic weighing system for wheel
loaders. It is automatic in the respect that the load in the bucket is weighed
without any involvement from the operator and dynamic as the weighing is
done while the machine operates normally without any interruption for
weighing.

LOADTRONIC 3 is type approved as Automatic Catchweigher according to
MID-directive MI-006 and OIML R51.

1.1 Sensors

LOADTRONIC 3 has two pressure sensors fitted to the hydraulics of the
wheel loader. These sensors measure the forces applied to the lifting arm
system, refer LOADTRONIC 3 Installation Guide.

There are two more sensors in the system:

x One angular sensor (inclinometer) which measures the position of the

lifting arms.

x One acceleration sensor which measures the movement (acceleration,

retardation and the inclination of the machine).

There is one switch in the system:

x One bucket position switch to signal when the bucket is fully retracted.
x In addition, the system is connected to the reverse signal of the machine.

1.2 Main Unit

The main unit is a combined operator’s display and a computer unit. The
main unit is mounted on the right corner post in the cabin, and has the
following functions:

x To read sensor signals.
x To compute and analyze measured data.
x To control the automatic weighing function.
x To record and report the weighing results.

Fairbanks Scales

page 6

x To carry out calibration and similar functions when the calibration switch

is set to the enabled position.

x To present measurement results on the LCD display.
x To receive commands from the operator through a keypad and a set of

function keys.

1.3 Calibration Switch

The calibration switch is placed underneath the main unit, refer Figure 1-1.
Calibration is enabled when the switch is in the rightmost position. Ensure
that the switch is in the leftmost position (calibration disabled) during
normal operation of the LOADTRONIC 3.

Figure 1-1 The Calibration Switch is placed underneath the Main Unit.

1.4 Printer (Optional)

The printer is connected to the main unit and positioned as required.

The printer has the following functions:

x Print a load receipt for each truck load.
x Print reports about customer, truck, material, location and load list.

If a printer is connected, you can print a load receipt by pressing the function
key next to the printer symbol (F2). Print/F2 will automatically cancel/zero
the running accumulated total for the current active job.

OPERATOR’S MANUAL page 7

1.5 Remote Wireless Communication (Optional)

Wireless communication is used for up- and downloading data between the
wheel loader and a remote location.

CHAPTER 3 Operating LOADTRONIC 3

3.1 Start –Normal Operation

LOADTRONIC 3 starts up as the machine’s ignition key is set in position 1
(running position) and the power switch at the rear of the main unit is
switched ON/1. After a few seconds a start up window is shown in the
display; next the system enters automatic weighing mode.
LOADTRONIC 3 is now ready for automatic weighing, refer chapter 3.2.
The currently active job record is shown in the lower part of the display; if
all records have been cleared (no active record) job record 0 ‘Unspecified
Recording’ is displayed.

Note:

If the instrument is directly connected to the machine battery (optional,
refer the LOADTRONIC 3 Installation Guide), the activation time is less
than 1 seconds if the engine is stalled; normally activation time is
approximately 10 seconds. The direct connection to the battery will also
provide power to the thermostat controlled heating element (optional) for
operations in very cold locations.

If the machine has been idle for more than two hours, LOADTRONIC 3
will block weighing, and request the operator to carry out a manual
zeropoint adjustment, refer chapter 3.6.

3.2 Automatic Weighing

Normally the LOADTRONIC 3 is in the mode for automatic weighing.

Automatic weighing means that the operator can operate as usual; during
normal operation the weighing sequence is activated automatically when the
wheel loader is reversed out from the material heap after filling the bucket.
Refer Figure 3-1 for an illustration.

The weighing begins as soon as the lifting arms have moved within the
weighing range, providing that other sensor signals are acceptable.

During automatic weighing the display unit shows, refer Figure 3-2:

x Load of the current bucket (Material weight), e.g. 5.15 t.
x Rest (Remaining material to be loaded (the required final weight -

(minus) total load so far).

x Running Total weight loaded so far, e.g. 17.00 t.
x Number of buckets loaded so far, e.g. 3.
x Attachment: ID number of the current attachment.
x Number of Active Jobs.
x Active Job (details).

Note: If the bucket is not fully tilted rearward, the message:‘BUCKET’
will be shown in place of the bucket weight (no weighing performed).

Comments:

x When weighing begins, the Load-field starts to flash, and the value is

updated.

x Weighing is completed when the weight of the current load is added to the

running total. The buzzer will give a sound signal if activated in
Parameter Setup II, refer Figure 3-6 and LOADTRONIC 3 Installation
Guide.

x The total weight and the rest weight to be loaded will be updated.
x The weight of the last bucket remains displayed until the load has been

dumped.

x Press Print/F2 to clear the job and print a receipt (if a printer has been

installed), or press C/F1 to clear the job (no report).

3.2.1 Tips for best results when weighing

Maximum function and accuracy is achieved by avoiding substantial
deviations from the usual work cycle, while at the same time noting the
following points:

x The LOADTRONIC 3 is activated/made ready for weighing 2 seconds

after the gear selector has been moved into reverse. During this time the
bucket should be pulled out from the material heap so that no friction
forces between the heap and the bucket will affect the weighing result.
This particularly applies if the bucket has been raised fairly high while
filling it.

x The lifting arms must be moving upward to initiate the weighing.
x If it should happen that the LOADTRONIC 3 does not become activated /

begin weighing, it is possible to activate manual weighing by pressing #,
refer chapter 3.4.

x The bucket must be tilted rearward to its end-stop when weighing,

otherwise the message ‘BUCKET’ will appear on the display.

x The lifting arms must be lifted into the measurement area, refer Figure

3-1.

x The lifting arms must not touch against the front frame or the machine

body when the weighing begins. This could cause false readings. This
means that:

o It is possible to control at which point in the work cycle the

weighing should be done by awaiting raising the lifting arms until
the machine has reached a suitable destination.

o When loading, transporting and dumping the load at a low height,

e.g. down a slope, it is necessary to raise the bucket before
emptying it to allow weighing to take place.

x When weighing on ground which is inclined more than 5 %, it is

recommended that weighing should be avoided at low lifting angles
particularly when the machine is pointing downhill. The system will only
weigh when the tilt is less than 10 %.

x If the operator wants to weigh the load under controlled conditions, he can

cancel the current weight and re-weigh the load, refer chapter 3.7 and 3.9.
If the bucket has been emptied, the cancel function must be used. At
manual activation a new weighing sequence starts immediately. When
canceling before dumping, the system must also be activated for a

OPERATOR’S MANUAL page 15

renewed weighing by moving the gear selector from forward or neutral to
reverse.

3.3 Recording

LOADTRONIC 3 records each operation when the system is active
(LOADTRONIC 3 is not active in pause mode, refer chapter 3.10). The
recording is linked to a specific job record, with or without reference to a
specific type of truck, material, customer or location. Data are stored
internally in the main unit; data can be inspected and printed for a customer
receipt. The current active job record is shown in the lower part of the
display.

3.3.1 Job Record

The LOADTRONIC 3 system can hold job details for as many as 999 job
records. A specific job record can be activated by e.g. pressing the job record
number directly on the keypad. The operator can receive a set of job records
to perform prior to the working day, and/or the operator can assign details
during the day.

Job record 0 is for unspecified recordings. The operator can temporarily
type/set job details for job identification in the records list for reporting etc,
but the details are not stored in job record 0 for later use; the job details are
unspecified the next time job record 0 is opened.

Job records 1 to 999 are for specified recordings. The job details that are
assigned to a specific job record are stored until changed by the operator.

A job record is active until the operator:

x Press Print/F2 to print a report.
x Press C/F1 to clear (no report).

Refer chapter 4.1 for a description of managing a library of customers,
materials, trucks and location.

page 16

Fairbanks Scales

3.3.2 Unspecified Recording

LOADTRONIC 3 allows the operator to perform an unspecified recording; a
recording of material weight without any specification of the material type,
truck, customer or location.

The operator can specify the target load before the job starts; either to set the
maximum permitted load limit for the truck or hauler, or to set a pre-defined
amount of material requested by the customer, refer Figure 3-4.
After each weighing LOADTRONIC 3 will display the weight of the current
bucket, the running total weight and the remaining weight to be loaded, refer
Figure 3-3.

If the operator does not specify the target load for the job, the field for the
remaining weight will be blank. The current weight of the bucket and the
running total weight will be displayed.

Figure 3-3 Job record with specified target load.
