Process mode
1、Check whether the charging voltage of the UPS terminal is reasonable. If the
charging voltage of UPS exceeds the setting value, please contact the UPS
manufacturer for solution.
2、Check the maximum setting voltage of battery terminal, and check the protection
parameters setting through LCD or VISION APP.
Check the minimum setting voltage of the battery terminal, and check the protection
parameters setting through LCD or VISION APP.
1. Check whether the charging current of the UPS terminal is reasonable. If the
charging current of UPS exceeds the setting value, please contact the UPS
manufacturer for solution.
2. Check the maximum setting charging current at the battery end, and check the
protection parameters setting through LCD or VISION APP.
1. Check whether the output power of UPS terminal is overloaded, and whether the
actual power conforms to the setting value. If the output power of UPS exceeds the
setting value, please contact UPS manufacturer for solution.
2、Check whether there is any problem with the internal control circuit of the master
control CBMS. Please also contact our company.
Check whether the indoor environment temperature is reasonable. If it is, check the
minimum charging temperature parameters set in the system, and check the
temperature is below the protection parameters setting through LCD or VISION APP. When the temperature
rises to the reasonable value, the battery will be recharged. After the above process,
if the same problem repeats, completely power off the system and then check the
battery module.
