1. INTRODUCTION
The LOADRITE weighing 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 Weighing System are:
the Indicator installed in the cab of the loader, and the connected sensors installed on the lifting arms.
As a load is lifted, the trigger and hydraulic pressure transducers send information to the LOADRITE Indicator. This information is converted into a digital weight reading that is displayed on the LOADRITE Indicator.
The LOADRITE Weighing System can add each lifted load to running totals so that T rucks are loaded accurately and daily productivity levels can be tracked.
The LOADRITE Indicator is the main user interface with the LOADRITE Weighing System.

1.4. ACCURATE WEIGHING
For maximum accuracy, ensure that:
Check Zero is performed regularly. Load lifting motion is steady and smooth, with no acceleration or bounce. The bucket is fully rolled back during the lift. The loader is on level ground.
1.4.1. Obtaining the Best Weighing Results
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
Start the lift well below the Trigger Point. This ensures that all acceleration and load bounce has been eli m inated well before the weighing sequence begins.
NOTE: We recommend that there are at least two seconds of lift before the Trigger Point.
Bounce
Most loaders have pneumatic tires which can cause the machine to bounce when lifting. To minimize the effect of bounce, always operate the lift lever before accelerating the engine and start the lift well below the
trigger point.
Center of gravity
The hydraulic pressure in the lifting cylinders depends on where the center of gravit y of the load is. It is important that the bucket is always in the same position: fully rolled back.
1-9
2. THE DAY-TO-DAY WEIGHING PROCESS
The following is the basic process for day-to-day weighing with the LOADRITE Weighing System:
1) Turn on the Indicator.
2) Perform a warm-up.
3) Zero the empty bucket.
4) Weigh and add each bucketload.
5) When you have finished loading the truck, clear the short total.
6) When you have finished using the LOADRITE Weighing System, put the Indicator into Standby mode.
2.1. HOW DO I TURN ON THE INDICATOR?
The LOADRITE Indicator will turn on automatically when you start the loader.
2.2. HOW DO I PERFORM A WARM-UP?
For best weighing accuracy, the hydraulic fluid in the lift cylinders should be at normal operating temperature. This is achieved by raising and lowering the empty bucket.
The above message will display if the Indicator has been turned off for more than one hour. If you see the above message, you need to raise and then lower the empty bucket past the Trigger Point three times:
1) Raise the bucket past the Trigger Point.
2) Lower the bucket past the Trigger Point.
3) Repeat two more times until the message disappears. When the warm-up has completed, the Ready screen will display.
2.3. HOW DO I ZERO THE EMPTY BUCKET?
The Check Zero functionality is only available if selected at installation.
It is necessary to periodically "zero" the Indicator because small errors can occur due to a build-up of material in the bucket.
If you see the above message, you need to zero the empty bucket. The message will display:
Every 15 minutes for the first hour, and Every 30 minutes thereafter (the default period is 30 minutes, but it may be set between 15-180 minutes).
Complete the following to zero the bucket:
IMPORTANT: When weighing a load, the loader must be level, and the bucket must be empty and kept fully-rolled back.
1) Ensure that the loader is level and the bucket is empty.
2) Raise the empty bucket.
3) Press The Zero Updated message will display, before the Ready screen is displayed.
.
2-10
2.4. HOW DO I WEIGH AND ADD A LOAD?
Depending on the settings selected at installation, there are two possible methods for weighing and adding loads:
Method Definition
Bucket loads are weighed when the vehicle is stable for a specified amount of time.
Static Weighing
This method is ideally suited for small wheel loaders and forklifts where a short pause in the loading cycle time will not significantly impact productivity.
Trigger-Point Weighing
Bucket loads are weighed when lifted past a specific point. This method is ideally suited for vehicles where the loading cycle time must be as short as possible.
2.4.1. Static Weighing
When the Total screen is displayed and the (Trigger light) has illuminated, bucket loads can be weighed. IMPORTANT: When weighing a bucketload, the loader must be level with the bucket kept fully-rolled back.
1) Lift the bucket load until it is stable (Depending on your settings, you may see the live weight of the bucket load b efore it stabilizes).
The Indicator will beep, display.
2) Press A message will display the number of buckets added to the current load, for example Bucket Add #1.
When the load has been added, the Total screen will display with the new short total and the number of added buck etloa ds.

This function allows small changes to be made to the LOADRITE Weighing System calibration if the bucket is modified, or if no accurate test weight was available when the LOADRITE Weighing System was calibrated at installation time.
The adjustment is carried out by entering the total weight recorded at a weighbridge (scale house) and the corres ponding total provided by the LOADRITE Indicator.
To perform the adjustment, a security access code must be obtained from your LOADRITE installer. CAUTION The LOADRITE Weighing System alters its calibration every time this function is used. It is important that this
function is only used once with a given set of data. If the same weights are entered again, the LOADRITE Weighing System will over-correct and its accuracy will be seriously impaired.

7.1. CHECKING THE ADJUSTMENT
The Span Calibration Adjustment can be checked by obtaining and comparing new LOADRITE and weighbridge values. If necessary, the Span Calibration Adjustment can be performed again using the new data.
IMPORTANT: All trucks and trailers should have tare weights confirmed for all loads to be checked. This ensures that a true weight can be established. Avoid split-weighing the truck and trailer.

8. APPENDIX C: ERROR MESSAGES
Error messages may be displayed for a variety of reasons as detailed below.
8.1. 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.
Depending on the installation of the particular LOADRITE Weighing System, there are two poss ibilities:
No weight is displayed and therefore there is no weight to add. Repeat the lift. Weighing Error is turned off and a weight is displayed. Add the weight to the total (bearing in mind that the weight
measurement is not reliable) or ignore this weight and repeat the lift smoothly.
8.2. CHECK POWER
The power supply has reached an unstable level. Check that the power source is stable and between +12V and +32V.
8.3. CHECK MAG/OPT
There is a fault in the magnetic or optical trigger or the cable that connects the trigger. If using an optical trigger, check that the lens is clear and dust-free.
8.4. CHECK ROTARY
There is a fault in the rotary trigger or the cable that connects the trigger. Check that the trigger is still securely mounted and that the trigger finger has not been damaged.
8.5. CHECK SCALE#
This message displays when is pressed if the Indicator is set up for use with multiple scales. If the weight is greater than 10% of full bucket capacity for the selected scale number, the screen displays Check Scale#
message. The operator needs to ensure the correct scale number is selected for the attached implement , as implements differ considerably in weight.
8.6. CHECK TILT
There is a fault in the tilt sensor used for ground slope compensation or the cable that connects the sensor. Check that the tilt sensor is still securely mounted and that the cable has not been damaged.
8.7. CHECK TRANSDUCER
There is an error in the pressure transducer signal input. This indicates a fault in either the pressure transducer or the cable that connects the transducer.
8.8. CHECK ZERO
The operator is automatically reminded to zero the bucket.
8.9. LIFT UNDER RANGE
The lift pressure was too low. This indicates a fault in either the pressure transducer or the cable that connects the transducer.
8-26
8.10. NO LOCK
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 therefore there is no weight to add.
8.11. OVERLOAD
The lifted weight exceeds the full scale (capacity) setting. If the Overload Error is set during installation, overloaded weight cannot be added.
8.12. POOR LIFT
If a weighing error is close to, but not greater than, the tolerance limit, the LOADRITE Indicator displays this warning message. The weight can be added as usual.
8.13. PRINTER DISABLED
Print function has been disabled at installation.
8.14. PRINTER ERROR
There is a fault in the printer. Check that the printer is online and has paper.
8.15. RETURN UNDER RANGE
The return pressure was too low. This indicates a fault in either the pressure transducer or the cable that connects the transducer.
8.16. SPEED CHANGED
For accurate measurement, the speed of raising the lift arms must be smooth, without acceleration or deceleration. The LOADRITE Weighing System can detect changing speed as the arms go past the Trigger Point. Depending on the installation of the LOADRITE Weighing System, there are two possibilities:
No weight is displayed, and therefore there is no weight to add. Repeat the lift and avoid accelerating and decelerating at or
near the Trigger Point.
A weight is displayed. Add weight to the total (acknowledging that the weight measurement is not reliable) or ignore this
weight and repeat the lift smoothly.
8.17. SPEED TOO HIGH
This message displays if the speed of raising the arms is too fast and exceeds predefined limits. Lift the arms again slower. If the message displays again, there may be a fault in the system. The LOADRITE Weighing System
should be checked and, if necessary, re-calibrated.
8.18. TILT TOO HIGH
The angle of the loader is at an unsafe roll or pitch while weighing. The Tilt Too High message accompanies the specific roll or pitch error at the top bar of the display.
8-27
8.19. TOO HEAVY, ZERO ABORTED
If the weight of product in the bucket is greater than 10% of full bucket capacity when is presse d, the screen displays this message and does not alter any settings. This prevents any accidental zeroing of valid weights.
NOTE: If the bucket is empty and the message still occurs, there may be a fault in the system. The LOADRITE Weighing System should be checked and, if necessary, re-calibrated.
8.20. WARM-UP LIFT
This message displays if the LOADRITE Indicator has been turned off for more than one hour, prompting a warm-up lift.
8-28
