Before commencing work with the SC Payload system, ensure that the system has been properly configured. Consult Smart Construction helpdesk for assistance if needed.
1. Unloaded Calibration
Ensure that an unloaded calibration has been completed for the bucket that is currently on the machine.
Instructions for unloaded calibration can be found here : Unloaded Calibration Routine
2. Hydraulic Oil Temperature
Complete the unloaded calibration with the hydraulic oil temperature at standard operational temperatures, and try and maintain the hydraulic oil temperature within standard operational range (recommended temp - 40-50 degrees C).
Hydraulic oil temperature will have a direct impact on oil viscosity which can alter the readings on the hydraulic pressure sensors, and therefore less accurate readings are possible if hydraulic oil temp is too cold or too hot.
3. Machine Stability
For best results, aim to position the machine on as flat and level ground as possible. Additionally confirm that the ground is stable so that the body does not rock around when lifting or slewing.
4. Machine Operation
When using the payload meter, the sequence for calculation of the load in the bucket is as follows:
“Digging" → “Load swing" → “Loading" → “Return
Payload calculation is performed based on the boom cylinder pressure during the load swing operation.
By following the recommended work method, you can improve the accuracy of the payload calculation.
-
Press the "▶" button to begin use of the payload function.
-
After digging, raise the boom while turning.
-
While swinging, the boom should be raised and turned for at least 3 seconds (guideline: turning angle of 45 degrees or more).
-
Please ensure smooth boom raising operation from the start of the payload swing to the end of the swing.
-
Do not perform any sudden boom operation while load is being weighed (sudden start of movement or sudden stops of swing). The payload value can be calculated more accurately if the boom cylinder hydraulic pressure is stabilized.
-
Do not raise the boom fully before swing, （Any boom raising operation that does not involve a swing cannot be considered a "load swing" and the payload value cannot be calculated correctly)
３．Dump the bucket and remove the soil. When the payload value is determined; it will be added to the calculated total amount of the truck being loaded.
-
Return to the material being loaded and repeat steps 1 to 3.
