1. General Information
1.1 Introduction
The Loadrite system measures the weight of loads lifted by wheel loaders,
forklift trucks and similar machines that use hydraulic rams to lift the load. The
main parts of the Loadrite system are the console, installed in the cab of the
loader, and connected sensors, installed on the lifting arms.
As the load is lifted, the trigger and hydraulic pressure transducers send
information to the console. This information is converted into a digital weight
reading which appears on the Loadrite console in your cab.
The Loadrite system can add each load lifted to running totals, so that trucks
can be loaded right the first time and daily productivity levels can be tracked.
The Loadrite console has an internal memory that stores settings and
production data even when it is switched off. Below is a schematic diagram of
a typical console. This is the main user interface with the system.

1.3 Loadrite models
There are various Loadrite models available to suit different operations. All
models share the same basic feature set, and some have additional advanced
features.
This user guide will outline the total range of features and associated operating
instructions that are found across the range of console models. For information
about which features each of the models have, consult the Loadrite system
comparison table in Appendix C.
Loadrite Pro
The Loadrite Pro model has the most advanced feature set of all Loadrite
weighing systems, and is the most popular model. It has extensive data
capabilities, which allow you to track the productivity of your operation.
Loadrite Express
The Loadrite Express model is designed as an entry level product for data
management. The Express offers advanced printer options and supports the
Loadrite Material Management System (MMS), providing you with options to
monitor and report on productivity. The Express features scrollable keys on the
console that enable fast and easy product and customer data entry
Loadrite Pit Boss
The Loadrite Pit Boss is a productivity reporting solution specific for pit
applications in quarries and mines. The Pit Boss solution includes the Loadrite
Material Management System (MMS) software which allows you to measure
blast efficiency, pit productivity, cycle times and more. This gives quarry and pit
managers the visibility to monitor productivity in the pit.
Loadrite Force
The Loadrite Force is a high performace weighing system with fewer operating
functions, which makes the system easy and fast to use.
As with the Pro and Express models, the Force is multiple point weighing
enabled, which allows you to weigh on the move, without slowing down the
operator.
Loadrite Sprint
The Loadrite Sprint model has a very basic feature set and is ideally suited to
small wheel loaders and forklifts. The Sprint can be programmed to support four
separate weighing implements, which allows you to weigh with a selection of
pre-calibrated implements such as buckets or forks of different sizes. The Sprint
supports both the Loadrite Printer and Material Management System (MMS)
accessories, providing you with options to monitor and report on productivity.

Legal for Trade systems
Loadrite systems meet Legal for Trade requirements in various
countries. This enables material to be weighed and sold directly
from the loader. For more information and to find out if this is
an option in your country, please contact your local Loadrite
distributor.
Operating requirements for Legal for Trade systems differ slightly from normal.
These differences are outlined in the appropriate places of this manual.

1.6 Accurate weighing
For maximum accuracy, ensure that:
•
The loader is level.
•
Zero is performed regularly.
•
The bucket is fully rolled back.
•
Load lifting motion is steady and smooth, with no acceleration or bounce.
(Weighing during lift is otherwise fine.)
Lifting Speed
For best results, operate the lift lever before accelerating the engine so that
the machine does not rock as it lifts, i.e. use normal revs.
Trigger Point
It is recommended that you start the lift well below the trigger point. This
ensures that all acceleration and load bounce has been eliminated well before
the weighing sequence begins.
Note: It is recommended that there are at least two seconds of lift before the
trigger point.
Bounce
Most loaders have pneumatic tyres which can cause the machine to bounce
when lifting.
To minimise the effect of bounce, always operate the lift lever before
accelerating the engine and start the lift well below the trigger point.
Centre of Gravity
The hydraulic pressure in the lifting cylinders depends on where the centre
of gravity of the load is. It is important that the bucket is always in the same
position – fully rolled back.

2. The weighing process
The basic weighing process is set out in eight main steps in the following
pages. The steps are as follows:
2.1. Switch on
2.2. Warm up
2.3. Zero the empty bucket
2.4. The Ready screen
2.5. Weigh a load
2.6. Add a load
2.7. Subtract a load
2.8. Standby mode
2.9. Recall the load and change the running total
2.10. Clear the short total
2.11 Clear the Long Total
These steps will be outlined in this section, along with additional factors and
features that can be found on some or all of the models. The graphic below
lays out the basic sequence for the weighing process.

2.1 Switch on
To switch on the Loadrite console:
Your Loadrite system will power up automatically
when you start up your loader.
If the Loadrite system has been switched off for
more than one hour, the Warm Up screen will
appear when powered up.
2.2 Warm up
After you have switched on the Loadrite console, it is important that the
hydraulic fluid is warmed up. This is done by raising and lowering the hydraulic
arm of the loader.
To warm up the system:
Step A
When the Warm Up screen is displayed, raise
and lower the hydraulic arm three times. This will
warm up the hydraulic fluid. The Warm Up screen
will countdown 3,2,1 as you lift.
Step B
When the Loadrite system is ready, the console
screen will display ‘Ready’ and look similar to this.
10
2.3 Zero the empty bucket
It is necessary to zero the equipment because small
zero errors can occur due to a build-up of material in
the bucket. If the Check Zero screen appears next,
you need to zero the empty bucket. You will need to
repeat this process whenever Check Zero comes up
on your console screen.
To Zero the Loadrite system:
Step A
Check that the loader is level and the bucket is
empty.
Step B
Tilt the bucket fully back, then from near ground
level, raise the bucket smoothly – use normal
revs.
Step C
The console will beep and turn the TRIG light on.
The load weight will be displayed.
Step D
Now press ZERO. The screen will briefly display
‘Zero updated’ and then the Ready screen will
appear.
(Weights shown are examples only.)
11
The Check Zero prompt
The Check Zero Prompt function automatically
reminds the operator to check ZERO from time to
time. The Check Zero Prompt is an optional function
that is selected during installation.
When the Loadrite system is first turned on (if it has
been off for more than one hour) the console will
remind the operator to do a ZERO check.
This will occur:
•
every 15 minutes for the first hour
•
every 30 minutes thereafter (15-180 minutes).
Note: After the first hour, the Check Zero Prompt interval can set to anywhere
between 15 and 180 minutes. The default setting is 30 minutes.
A ZERO error can affect the accuracy of lifted weights, so it is important to do
a ZERO check regularly. The Check Zero Prompt will not occur if the operator
is checking the ZERO often enough.
Note: For Legal for Trade application, ZERO must be checked.
2.4 The Ready screen
When the Ready screen appears, the Loadrite system is in Total mode and
ready to weigh. Total mode is the default mode of operation. The number
displayed on the screen is the product total. In the example below, sand is the
current product of choice and the total is 0. Apart from the Sprint and Force
models, all Loadrite systems can track multiple products. A list of product
names can be programmed into the console.

When the Ready screen appears, you can begin weighing loads.
To weigh a load:
Step A
Before you begin weighing, check that the loader
is level.
Step B
O
P

P
Check that the bucket is empty.
Note: If you are using a Legal for Trade Loadrite
system, you must ensure that the Bucket-empty
light is on before you begin weighing.
Step C
Once you have picked up your material, make
sure the bucket stays fully rolled back during the
weighing process.
Note: With the trade Legal for Trade systems,
the Bucket-back light will turn on when the bucket
is detected to be fully rolled back.
Step D
Raise the material smoothly past the trigger
point. Use normal revs.
Step E
The console will beep and turn the TRIG light on.
The weight will be displayed (2200).
(Weights shown are examples only.) See section 1.6 Accurate weighing
13
2.6 Add a load
After weighing, the Loadrite will always wait for a few seconds for you to take
one of the following actions:
Press ADD to add the weight to the long and short totals.
Press — to subtract the load from the totals.
Press ZERO to zero the measuring system.
If you don’t press a key, the Loadrite beeps and prompts you to take action.
The Loadrite then counts down and if you still don’t press a key, it discards the
weight and goes back to the Ready screen.
Typically, the current load will be added to a running total. The console then
keeps a running short total of the load weights until it is cleared.
To add a load:
Step A
Raise the material past the trigger point. The
console will beep and display the load.
Step B
Press the ADD key (or use the Remote Add
button).
Step C
The total is updated and the console returns to
the ready screen.

NOTE: With Legal for Trade Loadrite systems, the
Bucket-empty light will turn on when the material
is emptied onto the truck.
Note: In Target mode, the display is different. For details, see section.
Additional features associated with the add function are:
•
Remote Add button – an additional add button mounted close to the loader
controls.
•
Auto-add function – automatically adds the lifted weight to the total every
time a load is lifted.
Remote Add button
The Loadrite system has an option to use a Remote Add button. If this feature
is fitted, it is normally mounted near the lift lever. The remote add button can
be used interchangeably with the Add button on the keypad.
Lift lever
Remote Add button
The Auto-add function
Auto-add is an optional feature that is selected during installation. If Auto-add is
enabled, the Loadrite system can automatically operate the ADD function every
time a load is lifted past the trigger point.
15
To turn Auto-add on and off:
The Auto-add indicator light illuminates when the
Loadrite system is in Auto-add mode.
A. Press
B. Use
to access user menu.
to scroll to Auto-add.
C. Press ENT to select.
D. Use
to adjust the setting.
E. Press ENT to accept the setting.
Zero when the Auto-add function is on
The procedure for zeroing is different when Auto-add is on and Auto-add time
is set to 0.
To zero when the Auto-add feature is on:
Step A
Before you begin lifting, press the ZERO key.
Step B
Raise the empty bucket smoothly past the
trigger point.
The Loadrite system beeps and performs the
zero adjustment.
Note: If Auto-add is not on, or Auto-add time is not set to 0, follow the
procedure in section 2.3 Zero the empty bucket.
16
2.7 Subtract a Load
This function can be useful when only part of a final load of loose material
is required. You can add the full load, then once you have tipped off just the
amount needed into the object you are loading, you can re-weigh and subtract
the amount remaining in the bucket. Another example is when a log has been
added and then removed from a truck.
To subtract (subtract part of) a load:
Step A
Before the load is lifted, the Ready screen will
show.
(Current total 5600)
Step B
Raise the load smoothly past the trigger point.
The console beeps and displays the load.
(Weight of load 2200)
Step C
Now press the — (subtract) key.
The Loadrite system updates the total and the
console returns to the Ready screen.
(New total 3400)
Note: In Target mode, the display is different. For details, see section 3.2
Target mode.
17
2.8 Standby mode
If you are not using the Loadrite system, you can put
it in standby mode. Standby is useful when you are
stockpiling, as the console will not beep and prompt
you with a weight reading every time a weight is lifted.
The Loadrite system will automatically go into standby
if it is not used for two hours.
To go into standby:
Step A
Make sure the Ready screen is showing.
Then press the EXIT key.
Note: To restart the Loadrite system, press any key.
Note: The system will store production data that has been entered even when
it is switched off or in standby mode.
18
2.9 Recall the load and change the running total
The Recall function is equivalent to lifting the same load again and can be used
to correct mistakes. You can recall and display the last load if it has been:
•
added
•
subtracted
•
timed out (ignored)
To recall a previously lifted weight:
Step A
Press
key
(Current total = 5600)
Step B
The Loadrite beeps and displays the last load.
(Weight of last load = 2200 – arrow)
Step C
Adding or subtracting:
• If the last action was an ‘add’, you can subtract
this by pressing the — key.
• If the last action was a ‘subtract’, you can add it
on by pressing the ADD key.
The example on the right shows subtracting a
load that was previously added (i.e.5600 – 2200)
and the new total is 3400.
Note: If you press a key that is not relevant, such as ADD when the recalled
load was previously added, the Loadrite system ignores the key press.
19
2.10 Clear the Short Total
The Loadrite system keeps a total of the load weights that you add. For each
product, two independent totals are stored: the short total and the long total.
Note: If the Loadrite system has a printer connected, the totals are printed
before being cleared.
Definitions of short and long total:
Short Total
Generally used to display the total weight lifted onto an
object (e.g. truck or carriage).
As you add successive loads, the console displays the
updated Short Total (sum of the loads so far) on the
Ready screen.
Long Total
This keeps track of the total weights lifted over a longer
period, for example a shift or a day.
To view the Long Total, press
.
Clear the Short Total for the current product
The short total keeps accumulating until it is cleared. You will need to clear the
short total when you have finished loading. For example, you might clear it after
each truck or carriage load.
To clear the short total:
Step A
The console will display the short total for the
current product.
Step B
Press and hold the CLEAR key.
20
If the Loadrite system has a printer connected,
the total is being printed.
Step C
The Total Cleared screen will come up
automatically.
Step D
Returns to the Ready screen.
The next Add operation starts a new Short total
for this product.
21
2.11 Clear the Long Total
View the Long Total
At the end of a shift or longer period of time, you may want to clear the Long
Total of the product/s you have been weighing. You may also want to view the
Long Total periodically throughout the day.
To view the Long Total for the current product on the Loadrite Pro model:
Step A
Then press
to display the long total.
After a few seconds, the console automatically
returns to the Ready screen.
To view the Long Total for the current product on the Loadrite Express,
Pit Boss, Force and Sprint models:
Step A
Make sure the Ready screen is showing. Then
press
to display the menu
Step B
Use
arrows to scroll to the Long Tot screen
Step C
Press ENT to select.
After a few seconds, the console automatically
returns to the Ready screen.
22
To clear the Long Total for the current product:
Step A
Display the Long total using the method shown
above.
Press CLEAR.
Step B
The console asks you to confirm the clear.
Press ENT to confirm.
If the Loadrite system has a printer connected,
the total is being printed.
The console displays ‘Long Tot Cleared’ for a few
seconds and then returns to the Ready screen.
23
3. Operation Modes
The Loadrite system is able to add cumulatively the individual weights you have
loaded The main operation modes, as shown in the following table, allow you to
make different calculations as you go along.
The modes that are available in a particular Loadrite system model depend on
the product model and configuration during installation.
MODE
24
DESCRIPTION
Total
This is the normal mode of operation. As you add loads, the
weights are added to the totals. The short total is displayed.
Target
In this mode, a target weight is entered into the Loadrite
system before loading. As you add loads, the remaining value
to reach the target is displayed.
Batch
Batch mode allows you to weigh and load different products
according to a predefined recipe that specifies the required
proportions. The grand batch target is entered before
loading. The Loadrite system will work out individual product
weights needed.
Mix
This mode is similar to Batch mode except that the grand
target is not required. You load the first product to a certain
amount and then Loadrite will work out how much you need
for the other products, based on relative quantities in the
predefined recipe.
Blend
Blend mode allows a fixed number of loads of different
products, according to a predefined recipe.
3.1 Change mode
If more than one of the above modes are enabled, you must first select the
operation mode you want to enter.
To select a mode:
Step A:
Then press TARG.
Step B
You can either stay in current mode or press
to scroll to find another mode–Batch, Mix
or Blend.
Step C
Press ENT to accept.
Note: If your Loadrite has only one of Target, Batch, Mix or Blend mode, there
is no need to scroll–simply press TARG to access the
required mode.
Returning to Total mode
To return to Total mode from any of the other modes, press and hold
For Batch, Mix and Blend modes, you will automatically return to Total mode
when you clear the grand total, or when you select a product that is not in
the recipe.
25
3.2 Target mode
Target mode is typically used when loading an object to its optimum payload.
This feature provides an easy way to load up to a target weight for a product in
a series of lifts. In Target mode, the console displays the ‘To Load’ value, which
is the remaining amount to reach the target.
Before loading, the operator enters a target weight. Each time you add a
weight, the ‘To Load’ value is reduced by that weight.
Target mode is an optional feature available to most Loadrite models and is
selected during installation.
To enter Target mode (and input a new target):
Step A
Clear the previous total (see sections 2.9 Clear
the Short Total and 2.10 Clear the Long Total).
The Loadrite is in Total mode at this point.
Step B
Press TARG.
The console displays the last target value used.
Step C
If the new target is 9000, for example, use the
numeric keys to enter 9000.
Then press ENT to accept.
Step D
The console displays Target Updated for a few
seconds and then returns to the To Load screen
in Target mode.
26
Note: As your ‘To Load’ value approaches zero, you are getting close to
finishing loading a truck. You may not reach zero exactly, but should aim to
be close.
If you reach a positive ‘To Load’ value, you are under the target. If you reach a
negative ‘To Load’ value, you are over the target.
Reset the target
When you have finished loading an object, you need to clear the total or reset
the target.
To reset the target:
Step A
Press CLEAR.
Step B
The console displays Target Reset for a
few seconds.
Step C
The display is reset to the current target.
27
To return to Total mode
The To Load message indicates that the console
is in Target mode.
3.3 Batch mode
Batch mode allows you to weigh and load products according to a predefined
‘recipe’. You enter the target weight of the batch and the Loadrite system will
work out exactly how much of each product you need.
The recipe can contain up to ten products. It specifies the relative amount of
each product in a batch.
When it is in Batch mode, the console displays the ‘To Load’ value for each
product as it is weighed. This section will take you through all of the aspects
of the batch mode, including changing the recipe and operating within Batch
mode.
Batch mode is an optional feature of the Loadrite Pro model, and is selected
during installation.
Example
Suppose that a recipe of three products has been entered as follows:
PRODUCT
PROPORTION
Sand
4
Gravel
2
Pumice
1
When loading the three products, you specify the total load required; an
example might be 7000kg. The Loadrite system automatically calculates the
amount of each product required, which in this case would be:
Sand
28
4000kg
Gravel
2000kg
Pumice
1000kg
As you weigh and load the products, the Loadrite system maintains the
‘To Load’ amount for each product in a similar way to Target mode. You can
change from one product to another at any time in order to mix the products.
To enter the Batch screen:
Step A
Then press the TARG key.
Scroll until Batch mode is showing on the screen
and then press ENT to select it. You will see the
Recipe Confirm screen.
The Loadrite system automatically scrolls through
the recipe details after you have entered the
Recipe Confirm screen.
NOTE: If entering Batch mode for the very first
time, you will be prompted to enter a recipe (see
the following page).
At this point a number of operations are available:

3.6 Operating in Batch mode
In Batch mode, a batch total needs to be entered before loading. The Loadrite
system then maintains a ‘To Load’ target for each product in the recipe. Each
time that you add a weight, the ‘To Load’ value is reduced by that weight.
To use Batch mode:
Step A
The console displays the To Load screen with the
target value for the first product.

automatically returns to the Ready screen in Total mode.
.
You can also return to Total mode by pressing
3.7 Mix mode
Mix mode is similar to Batch mode except that a target value for the mix is
not required.
The recipe that you enter in Mix mode can contain up to ten products. It
specifies the relative amount of each product in a batch. You load the first
product to a certain amount and when you change to the next product, the
Loadrite system will work out exactly how much you will need to load based on
the relative amounts in the recipe.
When the system is in Mix mode and the primary product* is being loaded, the
console displays the word ‘Mix’ to indicate this. When you change to other products
in the recipe, the console displays the ‘To Load’ value for that particular product.
Mix mode is an optional feature of the Pro model and is selected during installation.
Example
PRODUCT
Sand
PROPORTION
4
* First item in the recipe is the
primary product.
Gravel

Pumice
1
Suppose that you have loaded 4000 kg of the primary product, sand. The
Loadrite system automatically calculates the amount of other product required,
which in this case would be:
Sand
4000kg
Gravel
2000kg
Pumice
1000kg
35
As you weigh and load the products, the Loadrite system maintains the ‘To
Load’ amount for each product in a similar way to Target mode. You can
change from one product to another at any time during weighing in order to
mix the products.

3.9 Blend mode
Blend mode is similar to Batch mode except that the recipe contains the total
number of loads of each product and you do not enter a target load. The
recipe can contain up to ten products.
When weighing, the Loadrite tracks the number of lifts of each product and
automatically changes to the next product when the required number of lifts
has been achieved.
Blend mode is an optional feature of Pro model and is selected during
installation.

After the last bucket of the first product has
been loaded, the console automatically displays
the second product name for you to start loading
that product.
After the last bucket of the last product in the
sequence is added, the Loadrite system starts
from the beginning of the sequence again.

3.11 Split mode
Split mode splits the total load weight into multiple sub-totals, providing an easy
way to load train carriages, or a truck and its trailer. You can also use this
mode to track load distribution over a single vehicle unit, to avoid overloading
an axial.
Split mode is only available on some models and is selected during installation.
Example
Suppose we are to load a truck with a trailer. The truck can carry 10 000 and
the trailer 15 000, the total therefore being 25 000.
The examples below show the operation of Split mode as it would appear in
Total mode and Target mode.

4. Advanced weighing functions
4.1 Tip-off
Tip-off weighing is the adjustment of the final load. You are able to tip a
measured amount of the product out of the last bucket to ensure an exact
target weight is reached, where the final load would otherwise exceed the
truck’s capacity. There are two different methods, depending on the way the
Loadrite system has been set up:
• Truck tip-off
• Stock pile tip-off.
Tip-off is only available on some models and is selected during installation.
4.2 Truck Tip-off
Using this method, you tip a measured amount of product from the bucket
into the truck and dump the rest. The following example illustrates the weigh
screen shots in both Total mode and Target mode.
To use the Truck Tip-off function:
EXAMPLE
Target weight
= 6000kg
Current weight
= 5600kg
Weight needed
= 400kg
Step A
Lift the load in the
normal way. The
console displays the
lifted weight (2200kg).
44
TOTAL MODE
TARGET MODE
Step B
Lift the bucket to a
suitable height over the
truck. Press
The Tip-off indicator
light comes on.
Console display:
Middle number shows
total weight as it is being
tipped onto the truck.
Lower number shows
weight tipped off onto
the truck.
Middle number shows
the weight still to be
tipped onto the truck.
Lower number shows
weight tipped off onto
the truck.
Step C
Roll the bucket partially
forward, tipping
product into the truck.
The screen on the right
shows that 300kg has
been tipped off so far.
The console displays
the total in the truck
and the amount that
has been tipped from
the bucket (i.e.400 kg).
45
the weight still to be
tipped onto the truck
and the amount that
has been tipped from
the bucket.
Step D
When the required truck load weight is reached, press ADD.
Step E
Finally, move away from the truck and dump any product remaining in
the bucket.
Notes on Tip-off function
• When tipping product from the bucket, do not raise or lower the lifting arms
as this would adversely affect the live weight reading.
• Tip-off cannot be used if Auto-add time is set to 0 sec (see section 7.5 Autoadd On/Off Setting (Auto-add)).
4.3 Stock Pile Tip-off
Using this method, you dump product from the bucket until it contains the right
amount for loading onto the truck. The following example illustrates the weigh
screen shots when in Total Mode and Target Mode.
To use the Stock Pile Tip-off function:
EXAMPLE
Target weight
= 6000kg
Current weight
= 5600kg
Weight needed
= 400kg
46
TOTAL MODE
TARGET MODE
Step A

target has been reached.
the remaining weight in
the bucket.
Step E
When the required weight is displayed, press ADD.
Step F
Tip the product from the bucket into the truck.
4.4 Tare
The Loadrite has two ways of using Tare and this is selected at the time of
installation. The Tare can work either with the lifted weight, or the total weight.
This is explained in more detail below.
The Tare function is only available on some models and is selected
4.5 Tare on Lifted weight
In this mode, the Tare function can be used, for example, to allow for the
weight of a pallet. When weighing, the Loadrite automatically deducts the tare
from the lifted weight and displays the net weight of the load.
4.6 Tare on Total weight
In this mode, the entered Tare value is applied to the displayed Total value. The
Loadrite system automatically adds the total for the currently selected product
to the Tare value and the console displays this value.
This mode is useful when loading vehicles that display their Tare weight and
maximum weight. The operator enters the Tare value into the console, then
loads the vehicle until the displayed total is equal to the vehicle’s maximum
loaded weight.
48
4.7 Enter a Tare weight using the keypad
You can enter a tare using the keypad or by measuring the weight. (When Tare
is set to work on the Total, the Tare value is normally entered with the keypad.)
See the example on the following page.
To enter a tare weight:
Step A
Then press
.
Tare? will appear on the screen, prompting you
to enter the tare weight.
Step B
Key in the tare weight and press ENT to accept.
49
4.8 Measure a Tare weight
A Tare weight can be measured by the Loadrite system. This is common when
finding the Tare weight of a pallet on the forks of a loader. (It is not normal to
measure the Tare weight when the Tare value is set to work on the Total).
To measure a Tare weight:
Step A
Lift the empty pallet past the trigger point.
The console beeps and displays the weight.
Step B
Press
.
The console displays the measured weight on the
Tare screen.
If necessary, edit the weight using the keypad.
Note: To turn on the tare function, enter a tare weight. To turn it off, enter a
tare of zero.
Note: Your Loadrite distributor will set up how Tare is to operate with
your machine.
50
5 Product management functions
Loadrite weighing systems can be used to track multiple products (materials).
Each product is associated with a product number, product name, Short Total,
Long Total and add-bucket counter. The product info screen enables you to
manage your products.
The product info screen not only allows you to select a different product, but
also displays information about the product before you select it.
This section will take you through a number of product management functions.
Some will only be found in the more advanced Loadrite systems (see the
system comparison table). The features covered are:
•
Selecting/changing products
•
Entering/accessing additional data fields
•
Auto target value look up
•
Automatic data prompt
•
Data suspend
•
Data download
5.1 Select a different product
To select a different product:
Step A
Step B
Press PROD.
The console will display the product name, the
Short Total and the number of buckets added.
Product name = Sand
Buckets added = 4
Short total = 3400
51
Step C
to scroll through the products, or
Press
key in a product number directly.
Press ENT to select the product you need.
Step D
The console briefly displays the Product screen,
and will display the Product you have selected.
The example to the right shows that Gravel has
now been selected for loading.
(Weights and product names are examples only.)
5.2 Data
If the data feature is enabled, you can identify your weight data with up to five
customisable data fields (of maximum eight characters). This helps to better
track and monitor your output. The number of data fields available depends on
how the Loadrite console has been set up at installation.
Typical data fields might be:
•
Data 1 = Customer (allows you to program in a customer name or number)
•
Data 2 = Docket (can automatically or manually assign each truck load with
a docket number)
•
Data 3 = Truck (allows you to enter a truck plate number)
This data can then be transferred via radio modem, stored in the Loadrite data
module and/or printed along with the weight data.
52
Data Edit
Before starting a new load (e.g. truck or carriage load), new data will need to
be entered.
An example of how you would enter a customer number on the Loadrite Pro
model follows:
Step A
Then press DATA.
The console displays the first field and prompts
you to enter the customer name or number.
Step B
Suppose the customer number is 1234.
Press 1 2 3 4
Then press ENT to accept the displayed value for
the data field.
Step C
The console automatically displays the next data
field (in this case Docket), which prompts you to
enter a value.
Note: to skip entering another value, press ENT
Step D
Once you have entered the value and accepted
all data fields by pressing ENT the console will
automatically return to the Ready screen.
53
An example of how you would enter a customer number on the Loadrite
Express model follows:
Step A
above the DATA label (e.g. DATA1)
Press
you wish to change. On the Express each of the
three data fields can be set separately.
The console displays the first field and prompts
you to enter the customer name or number.
Step B
Suppose the customer number is 1234.
Press 1 2 3 4
Then press ENT to accept the displayed value
for the data field. The console will automatically
return to the Ready screen.
Alphanumeric Data
The Loadrite system has an option to enter Alphanumeric (Alpha) data. This
option is enabled at installation time. The Loadrite system uses its telephone
style keypad to allow letters to be entered.
When a number key is pressed, a digit is displayed. If the same number key
is pressed again, the first letter on that key is displayed. If the key is pressed
again the second letter is displayed, and so on.
For example, if the
(Pro model) or
(Express model) key is pressed
repeatedly, the characters displayed in sequence are ‘2’, ‘A’, ‘B’, ‘C’, ‘a’, ‘b’, ‘c’,
‘2’, ‘A’ and so on. In this way, names can be entered for customers, trucks and
other data.
Note: Sometimes a name will have two sequential letters on the same key. For
example, the letters ‘D’ and ‘E’ in the word ‘DEAKON.
54
After the ‘D’ has been entered by pressing the
(Pro model) or
(Express model) key twice, wait a second or two. The cursor will automatically
shift and be ready for your next character.
You can then enter ‘E’ by pressing the
model) key again.
(Pro model) or
(Express
5.3 Name speed dial and scrolling
You can create a Customer List using the data fields. You can either use
keys to scroll through the list, or dial the index to the list to recall the name.
Suppose we have a customer list as follows:
Johns
Deakon
Smith
Johnson
Adams
The individual names can be found by scrolling in the following way:
To recall Smith:
1. Press DATA.
2. Press
until you see Smith on the screen, then press ENT.
To use speed dial to recall Smith:
1. Press DATA.
2. You can press 3 (the 3rd name on the list), then ENT.
Notes:
•
The data list can be printed out via the Print Function (see section 6.10
Print Data List Names).
•
Name speed dial requires the Data Index option to be enabled at installation
(Pro model).
•
Data List (name list) will not store names starting with numbers if name
speed dial function is active (Data Index option is enabled (activated)).
55
5.4 Auto Target Look-Up
This function enables you to store a list of target weights (for different trucks).
You can look-up the target weight from memory by either using speed dial (if
active) or scrolling through a list of truck names.
Scroll to look-up truck target
Below is an example of a truck and target list.
We configure Data 3 to store truck plate numbers and Data 4 to store the
corresponding target values.
56
•
Data 3 is an alphanumeric field and is set up as a target reference list.
•
Data 4 is set up as a target list.
DATA 3: TRUCK

Loadrite will then automatically use AUQ887 as
reference and look up the corresponding target
value
Step D
You will then return to the To Load screen.
Index to recall truck target value
A second example of a truck target list is set out opposite.
We configure Data 4 as a target list with the index function enabled. The order of
the list is important as we use the index numbers to represent different trucks.
58

To recall a truck target value in the indexing system on the
Loadrite Pro model:
Step A
Then press DATA.
You will be prompted for the first data field (Data
1: Customer). Since we use Data 4 for Target
list, you must first enter data for Data 1, Data 2,
and Data 3.
Step B
When you get to Data 4 (Target), the last target
value and the last index number will be displayed.
Step C
The Loadrite system will use the Index 2 and look
up the corresponding target value.
Step D
You will then return to the To Load screen.
59
5.5 Auto tare value look up
This function is similar to Auto target value look-up, except that it handles tare
values. You can recall the tare value from memory by either entering a number
or scrolling through a list of truck names. The procedures are the same as the
Auto target value look-up.
5.6 Auto-increment
Auto-increment function is an optional feature that is selected during
installation. If auto-increment is enabled, the data value will be made to
increment automatically when the Short Total is cleared.
5.7 Automatic Data Prompt
Automatic Data Prompt is an optional function that is selected during
installation. If enabled, the Loadrite system automatically prompts for data field
entries when a new product is selected.
This feature is only available on Pro models.
5.8 Data Suspend
Data Suspend is a feature that allows the operator to temporarily suspend all
data values and set them to 0 (zero). Data Suspend is an optional function that
is selected during installation.
This feature is only available on Pro models.
To suspend data:
Step A
Then press DATA.
The console will display the current setting.
Step B
Press the CLEAR key and then enter 0.
The console will then display a message to
confirm that the Data Suspend has been
activated.

de-activated.
As soon as the Data Suspend function is de-activated, the Loadrite system will
resume normal operation.
5.9 Data Download
Data Download is a feature that enables the operator to export the current
data list to a PC via the Loadrite Link software, where it can be saved
and/or modified.
61
6. Print function
All Loadrite consoles can print weighing data as you weigh loads. Some models
have internal memory storage to allow delayed printing and summary reports.
This is described in section 6.2 Print Menu. There is normally enough storage
for up to one day, depending on usage.
6.1 Printed Data

6.3 Print Docket
Print Last Docket function prints the data stored (e.g., ADD, SUBTRACT)
between the two last CLEAR events. If the data is not stored, it will not be
printed. For example, if the Loadrite is not configured to log ADD events,
weights added will not be printed. This function requires internal storage to be
enabled. All configuration of this function is set during installation.
Note: This function will not work if CLEAR is not used as intended. For example:
you are loading sand and halfway through, a second truck comes in. You switch
product to rocks and start loading to the second truck (without clearing total of
sand). When you run this function, you will get the added weights of sand plus
the added weights and total of rocks.

8. Error messages
Error messages will be displayed for a variety of reasons. The error messages
that you may encounter, as well as the explanations of action to take to correct
them, are displayed below.
“Bouncing Load”
If the lift arms are bouncing significantly while weighing, an error occurs. This
can happen if, for example, the loader is driven over uneven ground while lifting
the load.
The Loadrite system can detect a bouncing load and if this occurs, the console
displays the message ‘Bouncing Load’.
Depending on the installation of the particular Loadrite system, there are two
possibilities:
1. No weight is displayed and hence there is no weight to add. You should repeat
the lift. Avoid uneven ground as you lift through or near the trigger point.
2. Weighing Error is turned off and a weight is displayed. You can add the
weight to the total (bearing in mind that the weight measurement is not
reliable) or you can ignore this weight and repeat the lift smoothly.
“Bucket Empty?”
If you zero the bucket and there is some residue in the bucket, your Loadrite
system will detect how much is in the bucket. If the contents are less than
5% of the full bucket capacity, the Loadrite will zero he bucket. If the weight of
material in the bucket is within 5-10% of full bucket capacity when you press
ZERO, the console will display: “Bucket Empty?” to check that you in in fact
wish to zero the bucket.
To do this press ENT. This will zero the empty bucket. Pressing EXIT will not
zero the scale.
“Check Power”
The Loadrite system has detected that the power supply has reached the
unstable level. Check that the power source is stable and between +12V
and +32 V.
“Check Transducer”
The Loadrite system has detected an error in the pressure transducer signal
input. This indicates a fault in either the pressure transducer or the cable that
connects the transducer.
80
“Check Trigger”
The Loadrite system has detected a fault in the trigger or the cable that
connects the trigger.
Check that the lens on the optical trigger is clear and dust-free.
“Check Zero”
The Loadrite system automatically reminds the operator to check zero
occasionally. See Check Zero Prompt in section 2.3 Zero the empty bucket.
When this message appears you need to perform a zero lift.
“Lift Under Range”
The Loadrite system has detected that the lift pressure was too low. This
indicates a fault in either the pressure transducer or the cable that connects
the transducer.
“Module Data Lost”
The Loadrite system has an ability to store data internally in the event that the
LD941 data module is absent or full. The Loadrite system will generate this
message when the internal data storage is full and some data has been lost
as a result.
You need to install a new data module immediately to avoid further loss of data.
“Module Error”
The Loadrite system has detected an error when writing to the LD941
data module.
Check that the module is securely connected to the Loadrite.
“Module Full”
The Loadrite system has detected that the LD941 data module is full. The full
module should be removed for data transfer to the MMS software.
“No Lock”
No Lock means that the interlock was not closed when lifting the load.
The interlock must be closed (or the bucket must be fully rolled back) while
lifting the load.
No weight is displayed and hence there is no weight to add.
81
“Over Target”
Over Target means that adding the lifted weight will exceed the target value.
The lifted weight can still be added by pressing the ADD key.
Over Target message
Amount over the target value
Lifted weight
Note: the Auto-add function will not automatically add over-target weight.
“Overload”
Overload means that the lifted weight exceeds the full scale (capacity) setting. If
the Overload Error is set during installation, overloaded weight cannot be added.
Overload Message
Amount overloaded
“Poor Lift”
If a weighing error is close to but not greater than the tolerance limit, the
Loadrite system displays this warning message.
The weight can be added as usual.
“Printer Disabled”
Print function has been disabled at installation.
“Printer Error”
The Loadrite system has detected a fault in the printer.
Check that the printer is on-line and not out of paper.
“Return Under Range”
The Loadrite system has detected that the Return pressure was too low.
This indicates a fault in either the pressure transducer or the cable that
connects the transducer.
82
“Speed Changed”
For accurate measurement, the speed of raising the lift arms must be smooth,
without acceleration or deceleration.
The Loadrite system can detect changing speed as the arms go past the
trigger point. If this occurs, the indicator console displays the message “Speed
Changed”.
Depending on the installation of the Loadrite system, there are two
possibilities:
1. No weight is displayed and hence there is no weight to add. You should
repeat the lift. Avoid accelerating and decelerating at or near the trigger
sequence.
2. Weighing Error is turned off and a weight is displayed. You can add the
weight to the total (bearing in mind that the weight measurement is not
reliable) or you can ignore this weight and repeat the lift smoothly.
“Too Heavy, Zero Aborted”
If the weight of material in the bucket is greater than 10% of full bucket
capacity when you press ZERO, the screen displays: “Too heavy, zero aborted”
and does not alter any settings.
This prevents any accidental zeroing of valid weights.
Note: If the bucket is empty and the “Too heavy” message still occurs, there
may be a fault in the system. The Loadrite system should be checked and, if
necessary, re-calibrated.
“Warm Up Lift”
This message appears if the Loadrite system has been switched off for more
than 1 hour. You need to lift the bucket/forks a few times to warm up.
See section 2.2 Warm up.
83

APPENDIX B:
Loadrite terminology
The following table lists a range of terms and definitions that are used to
describe Loadrite products, features and processes.
92
Auto-add
Automatically adds the lifted weight to the total every
time a load is lifted.
Auto-tare
A feature that allows you to pre-programme tare
weights. The operator can then select a truck from
memory and the Loadrite will automatically display the
tare weight for that truck.
Auto-target
A feature that allows you to pre-programme target
weights. The operator is able to select a truck from
memory and the Loadrite will display the target weight
for that truck.
Batch mode
The Batch mode helps the operator to keep track of how
much of each product is required when you are working
to a set recipe.
Blend mode
The Blend mode keeps track of what is required by
bucket load quantity for each product in order to
formulate a recipe.
Bucket
Is used to describe the weighing implement that holds
the load while it is being transferred. Could also be
forks, for example.
Console
The visible Loadrite hardware that operators interface
with in the loader cab.
Data field
Fields that allow you to label your weighing data to
help you track and monitor your output e.g. by truck,
customer etc.
Data module
A memory device which can be attached to the Loadrite
console to store payload data.
Display
A large LCD screen with adjustable backlighting for
night and low light operations. Used to display weight
information and operator messages.
Inclinometer
A slope detection sensor that measures the tilt angle of
the loader. This is used in Legal for Trade applications,
where the weight is not qualified if the loader is on a
steep angle.
Interlock
Bucket back and bucket forward position detection
sensors. Used in Legal for Trade applications, where the
bucket must be fully rolled back for weighing and rolled
forward for emptying.
Keypad
The set of keys which allow you to operate the Loadrite
console.
Legal for Trade
Certification by a local weights and measures authority
to legally sell product from your loader.
Load
One discrete weigh lot or ‘scoop’.
Loader
The machine responsible for lifting the load e.g. wheel
loader, forklift.
Loadrite system
/ the system
Refers to the entire Loadrite system including the
console, transducers, sensors etc.
Long total
The long total is typically used to accumulate the weights
loaded over a long period, for example a shift or a day.
Model
The different Loadrite consoles Pro, Pit Boss, Express,
Force and Sprint.
Operation mode
Any mode that relates to the running total of
accumulated weights e.g. Total or Target mode.
Pressure
transducer
A pressure sensor, that is connected to the loader’s
hydraulic system to measure the hydraulic pressure
required to lift the load.
Primary product
The first item in a recipe is referred to as the primary
product.
Printer
The printer is mounted in the loader cab. It provides a
paper record of the weighing information collected by
the Loadrite system. It is an optional accessory.
Product/material
Material that comprises a load.
Radio modem
Used to transfer payload data, live, from the Loadrite
console, to the office.
Recipe
Some Loadrite operation modes allow you to enter
different quantities of materials to make up a recipe
which forms a product.
Remote add
button
An additional add button which is mounted in close
proximity to the loader controls. This feature enables
the operator to use this frequently used button without
having to take their hands away from the controls used
to operate the loader.
93
94
Short Total
Your Loadrite keeps a total of the bucket weights that
you add. As you add successive loads, the Loadrite
displays an updated total which is a sum of what has
been loaded so far, this is the short total.
Split weighing
The split weighing feature makes it easier for the
operator to load trucks with trailers. It gives the
operator the ability to run individual totals for loading
truck and trailer units.
Standby
All Loadrite systems have a ‘standby’ mode which is
similar to turning the Loadrite off. This feature is used
when the operator is moving the loader around and does
not need to weigh.
Tare mode
Tare mode gives you different options to work with
tare weights. The Loadrite system can calculate the
net weight of a pallet, for example, or notify when the
maximum vehicle weight is reached.
Target mode
The target mode feature enables you to enter a
predetermined target weight and your Loadrite will then
deduct each subsequent lift from the total until that
target weight is reached.
Tip-off
Final bucket load adjustment, which allows you to tip a
measured amount of the product off the last bucket to
ensure an exact target weight is reached.
Transducer
(see pressure transducer)
Trigger
A position sensor responding to the position of the lift
arms, which informs the system when to take a weight
reading. Loadrite systems have three types of trigger;
optical, rotary and magnetic.
Trigger point
A point in the position of the arms where a weight
reading is taken.
Weighbridge
A platform scale for weighing vehicles. Also referred to
as scale house and truck scale.
Weigh mode
Any mode that gives the operator different options to
weigh the material in the bucket e.g. tip-off or tare
mode.
Zero
Zeroing is required to zero the bucket from time to time.
This is to avoid inaccurate readings due to build up of
material in the bucket, which can occur when operators
are dealing with wet or sticky materials.
