1. Before the shift, check whether the weighing device is in normal working condition. If there is any jamming or other phenomena that affect the weighing accuracy, it should be eliminated in time.
2. Check whether the wiring of the electrical part is correct and firm, and whether the electrical box shell is firmly grounded.
3. During operation, check whether each operating part is operating normally, whether the conveyor belt is deviated, and whether there are foreign objects falling between the belt and the driven roller. If there is any abnormality, stop the machine immediately to eliminate it.
4. Grease should be added to each moving part, and the belt roller should be removed and refueled once a year.
5. When inspecting the machine, the machine must be shut down and the main power must be cut off.
6. The batching controller should have rainproof, sunproof and dustproof facilities.
7. Prevent sand and gravel from mixing with steel bars, large stones and other debris to avoid damaging the conveyor belt.
8. In order to ensure the safety of the batching controller, do not use it under severe weather conditions such as heavy rain, thunder, etc., and turn off the main power supply, remove the connection between the sensor and the batching controller to prevent damage to the controller.
9. The power supply voltage fluctuation must be less than -5 to 5%.
10. At least once a year, the weighing system must be calibrated according to the scale calibration method in the batching controller manual to ensure the accuracy of the weighing.
