The channels 1-5 shown directly below the loader scale’s screen are used for various attachments. In this example we’re only using one attachment in channel one. In this example the wheel loader scale is using the manual bucket add. Please refer to the Calibration process for how to change to auto bucket add.

Basic Scale Operation

Simply go into the pile, fill the bucket and lift. The loader scale will automatically begin weighing the load and display weight on screen. If you wish for the weight to be added to the truck total, simply press the “CLR” button or the Remote Enter Button located next to the hydraulic lever to add that weight. Loading a new bucket of material will display the weight once again, press the “CLR” or Remote Enter Button to add to the truck and you’ll notice the total increasing by that amount.

Clearing a Channel

To clear a channel, please note that you do not use the “ZERO” key. This is a common mistake made when operating the system. Instead, press and hold the Remote Enter Button to clear the channel back to read 0.

Totals Channel

Using the middle button, move the highlighted channel over to the “TOTAL” channel to display the total amount weighed. The same procedure of clearing the total is used as before, press and hold the Remote Enter Button.

Zeroing the Bucket

Zeroing the bucket refers to zeroing or canceling out any extra weight that may be stuck in the bucket. Press and hold the “ZERO” button and when the display is flashing, make sure the bucket is empty and perform a normal lift. If any extra weight is in the bucket, it will display briefly before being zeroed out.

Printing

The “PRINT” button is used as expected. If a printer is connect to the scale system, you would use this button to print a receipt of each load as needed.

Calibration Mode

To enter the calibration press and hold the “CLR” button and turn the unit on. It will display Cal 1 and the type of weighing and channel selected, which in this case is channel one and dynamic weighing is selected. If you wish to weigh in static weighing mode, press and hold the “CLR” button and push the middle button to change modes. Typically you would want to calibrate the Weighlog 200 skid steer scale in dynamic mode, since speed compensation will be used for all subsequent channels.

Manual and Auto Modes

For the next step, press the “CLR” button. The screen will now display the “Manual” mode, hold “CLR” and press the middle button to change to Auto mode. The difference between these refers to pressing the remote enter button each time you lift to add the load, where as Auto mode will add each bucket automatically. In this example we leave the scale in Manual mode.

Calibration Factor

Press “CLR” again to move to the calibration factor of the scale calibration. The screen will briefly display “CALF” before moving onto showing 1.000. This is the calibration factor that makes the Weighlog 200 read the proper amount of weight. In most cases leaving this number at 1.000 is acceptable and the wheel loader scale will calibrate if you leave this number as is.

Changing the Calibration Factor Number

To change the calibration factor number, you can press and hold the “CLR” button and press the middle button to cycle between digits. To change any particular digit, immediately press back down on the middle button to begin cycling through numbers on that digit.

Full Bucket Fast and Slow Lift

Press “CRL” once again to move on to the fast load step. For this step, fill your bucket with material and do a fast lift (at a high RPM). When done, the display will display a frequency number. Next press “CLR” again to move on to the slow lift. Repeat as before only at a lower RPM. A frequency number will display once again, at which point you may press the “CLR” button to move on.

Empty Bucket Fast and Slow Lift

As in the previous steps, the scale will ask you to preform a series of fast and slow lifts, only this time with the bucket empty. Note that the frequency number that’s displayed on the scale screen is much less than with a full bucket. Once both steps are complete press the “CLR” button to move to Zero lift.

Zero Lift

With the bucket still empty, lift the bucket at what the operator considers a normal RPM. A frequency number will display, press the “CLR” button to move to the next setup step.

Load with Known Weight

In this example the Weighlog 200 is set to read in tons. The screen displaying 1.000 is anticipating that you will be putting a known weight of 1 ton in the bucket. If it is not 1 ton, use the steps as described above to change the number to the appropriate weight. Press the “CLR” button to perform a regular lift. As before a frequency number will display, press the “CLR” button and the scale should say “Cal Done“.

Check for Repeatability

To make sure the calibration settings have been set correctly, it is recommended that you lift the same known weight for repeatability. Turn off the system and turn it back on without any buttons pushed, lift the same weight again and it should read the same weight as what you entered. This would confirm and complete your calibration.

Nudging the Scale

If for example the scale read the weight slightly off from what you entered during calibration, you would perform a nudge of the scale. To do this, press the “REF” key on the left while the bucket is in the air. All the icons around the outside of the screen should light up. While still holding the “REF” key, push the “PRINT” key to increase the weight to the correct amount. The “ZERO” key would lower the weight. Once the weight has been adjusted to the correct weight, the unit will be updated. Once the load is lifted again, the correct weight should now be shown in the scale.

When powered on, the Loup logo and revision of software will be displayed on screen. For any technical help you may need, the revision of software number would be beneficial.

Button Layout

On the main screen the buttons on the bottom (left to right) consist of a “0″ key used to zero the bucket at the beginning of the day. The next button is the auto/manual key, pressing this button will change the scale function to auto or manual. Next is the Clear 1 button for use in subtracting one bucket if you don’t want it loaded on the truck. The Clear button is used at the end of a load to clear the display and start the process over again.

Along the right side of the display are the Main, Store and Print buttons. The remainder of the keys consists of a traditional 0-9 keypad. The green “Enter” key corresponds to the white push button in the cab, referred to as the remote enter key. Below the flap is the slot for the SD card slot for the data card, this is used for data logging of loads and other customer data.

Zero the Scale

To begin each day, typically you would zero out the bucket by pressing the “0″ key below the screen, to the far left. It will then ask that you lift dynamically and statically. In this example a small weight of .04t was shown on the scale that was then zeroed out prior to operation.

Create a Load

The Loadlog 8000i has the ability to store up to 500 customers and 200 products. To create a load, you may press the “Store” button on the right side of the screen. That button will bring up a full list of customer list for you to choose from. Once you have selected a customer, push the “Enter” key which will then bring up the list of products for you to choose from. Select a product from the list and press “Enter”. At this point you will see on screen that both the Customer and Product you’ve chosen are displayed.

At this point you can begin loading the truck by simple loading the bucket and lifting. As you lift the bucket the weight is displayed. If you have the Auto add bucket feature enabled (2nd white button from the left below the screen) it will automatically adds the bucket load to the total. Once the load is complete you can hit the “CLR” button to finish the load. If at this point you have a data card or printer connected to the unit, the data would be recorded and a receipt printed showing the load details.

From here you may enter the Store screen again to select a different Customer or Product as desired.

Target Loads

Target loads can be entered in prior to starting a load by simply entering in the load amount and pressing the “Enter” key. The upper line on the screen now displays the target load. You may now push the “Store” key to select a customer and product if desired. Again the customer and product data is now displayed on screen. Now when the load is weighed and added to the truck, the weight is subtracted from the target load above. As more buckets are added to the truck, the target amount will continue down towards 0. If the last load is greater than the amount needed to finish the load, it will flash to indicate this. The operator can then lower the bucket to the static position and remove some product. Once the bucket load is within range, the load can then be added with the remote enter key. In this example it shows that the truck was under loaded by .04 tons, with 9.96 tons on the truck.

The target load entered into the unit will be displayed again until entered otherwise by the operator. This number can also be stored with the customer for future loads.

Clear 1 Load

If a load is added that you didn’t want counted, simply press this button to undo the load.

Auto/Manual Button

When in Auto mode, the bucket will automatically be added to the load as lifted. When in manual mode, the operator would need to press the remote enter button each time after the bucket is weighed to add it to the load.

Loadlog 8000i Calibration

This calibration process can be applied to either the Loup Electronics Loadlog 800i or 8000i wheel loader scales.

To enter the calibration mode, press the red “Pages” key, select option 1 for Calibration and enter the default factory pin of “4084” and press the green “Enter” key. From here select Auto calibration to begin the process.

Dynamic Full Lift

Once you select the Dynamic Full Lift, you would fill your bucket with material and do a fast lift. A fast lift would mean the wheel loader RPM is near it’s highest point for the lift. Once the lift is completed a series of numbers showing milliseconds (mS) , frequency (sensor A) and frequency (sensor B) are displayed. Note that sensor A should always be higher than sensor B.

Press the Enter key again to begin a slow lift with the same bucket of material. Because this video is using a simulator to operate the scale, the numbers displayed will be very similar to the previous lift. A machine out in the field would produce a different outcome. The numbers below are there to show the speed compensation that has been set.

Live Static Comp

In the weighing position you will see a set of bars appear on the screen while the calibration runs. Once it reaches the other end of the screen, the live static comp will be completed. Once complete, hit the escape key to proceed with the calibration.

Dynamic Empty Lift

Similar to the Dynamic Full Lift, this step requires no weight in the bucket for both a fast and slow lift. Begin by lifting the bucket at near top RPM, followed by a slow lift. note that the frequency of the sensors has gone down when compared to a Dynamic Full Lift. Press the enter key to finish the calibration.

Dynamic Zero

For this step lift an empty bucket at what you would consider a normal speed. It will then take the number from that lift and set the zero. It will then ask for the static zero, lift the bucket to the weighing position and the scale will automatically calculate the weight and set the zero.

Calibration Weight

In setting the calibration weight, the factors start at 1 for both Calibration A and B. With a known weight in the bucket, lift the load until the weight reading is displayed on screen. Then type in the known weight of that item to adjust the scale accordingly. The same process is done for weighing from the static position. Simply enter in the known weight and press Enter to continue. This will end the calibration. You can check for repeatability by weighing the same load again, only this time the screen should weigh that load as the amount you entered into the system. Same results should be seen when lifting in dynamic mode.

Nudging the Scale

If a nudge of the scale is needed after calibration is done, press the red Pages key and select the lower button next to the scale icon. From here you can enter the difference by entering the weight the scale was showing followed by the weight a truck scale shows. The system will automatically adjust the percentages to calculate all further loads.
