As one of the representatives of heavy construction machinery, Carter excavator is recognized by the industry for its working performance and stability. In daily operation and maintenance, it is important to understand and ensure that the parameters of each system are in order. Among them, the low-voltage system is a key link in the electrical system of the excavator, so how much is the normal low-voltage of the Carter excavator? Under normal circumstances, the low-voltage standard of the electrical system of the Carter excavator should be kept at about 24V, which is the standard voltage range of most excavators. However, the specific low pressure threshold may vary depending on the model, configuration and working conditions, it is recommended to refer to the official user manual of the excavator to obtain the accurate low pressure alarm setting value. In order to ensure the normal operation of the excavator, once the low voltage is abnormal, the power supply, circuit connection, battery capacity and charging system should be checked in time for failure. For Carter excavator users, regular inspection and maintenance of the electrical system to ensure that the low-voltage system is stable within the normal range is undoubtedly an important measure to extend the life of the equipment and improve work efficiency. In summary, monitoring the low pressure status of the Carter excavator is an important part of equipment maintenance, and the operator needs to pay close attention to and follow the manufacturer's guidance to ensure that the low pressure value is maintained within normal levels.
