FAQ

Battery Overvoltage

Battery voltage exceeds the upper voltage limit, confirmation time 0.2s

Use a multimeter to measure the actual battery voltage and compare it with the voltage displayed on the BTS to check if the sample values are consistent.
If the sample value and the actual value are not equal, confirm whether the issue is with the DC board or the wiring by swapping the sampling lines with adjacent channels. If the wiring is faulty, check for incorrect, loose, or poor connections in the voltage sampling lines.
If the sample value and the actual value are equal, check if the upper computer step settings are reasonable and determine if the battery overvoltage occurs as soon as the step runs or at a specific point during the step.
Check the corresponding battery for any obvious swelling, damage, or other abnormalities. If there are issues, take necessary safety measures.
If the battery and voltage sampling lines are normal, confirm that the DC board is faulty and replace it.

Battery Undervoltage

Battery voltage is lower than the lower voltage limit, confirmation time 0.2s

Use a multimeter to measure the actual battery voltage and compare it with the voltage displayed on the BTS to check if the sample values are consistent.
If the sample value and the actual value are not equal, confirm whether the issue is with the DC board or the wiring by swapping the sampling lines with adjacent channels. If the wiring is faulty, check for incorrect, loose, or poor connections in the voltage sampling lines.
If the sample value and the actual value are equal, check if the upper computer step settings are reasonable and determine if the battery undervoltage occurs as soon as the step runs or at a specific point during the step.
Check the corresponding battery for any obvious swelling, damage, or other abnormalities. If there are issues, take necessary safety measures.
If the battery and voltage sampling lines are normal, confirm that the DC board is faulty and replace it.

Communication Failure

Module 6S does not receive data from the upper computer, switches to fault state. The fault is automatically cleared when the module receives data from the upper computer.

Check if the module and the middle computer are in a normal powered-on state.
Check if the CAN connection between the module and the middle computer is normal.
Check if the CANA dip switch is set correctly.
Measure the matching resistance between CAN H and CAN L on the CANA bus. It should be 60±5 ohms. If not, adjust the matching resistance on the signal adapter board. If the bus voltage is normal, check the BTS fault records to identify which sub-channel triggered the fault. Use debugging software tools to check if the bus voltage displayed for that channel is normal. If abnormal, it can be determined that the DC board's bus sampling is faulty, and the board should be replaced.
If all the above points are normal, connect a CAN box and use the captured messages to determine whether the issue lies with the middle computer or the lower computer.
