Process mode
1、Check the charging voltage of the UPS terminal and check whether the
setting value is reasonable. If the charging voltage of UPS does exceed the
setting value, please contact the UPS manufacturer for solution.
2、Check the maximum setting voltage of cell, and check the protection
parameters setting through LCD or VISION APP.
After the above process, appropriately reduce the charging voltage to
alleviate this phenomenon. Over voltage of cell is a normal phenomenon.
Due to battery differences.
Check the minimum setting protection voltage of cell, and check the
protection parameters setting through LCD or VISION APP. If it is confirmed
that setting parameters are reasonable and the single under-voltage
protection occurs prematurely, please contact Vision.
Discharge and check whether the charging time of the system is
reasonable. If it is, completely power off the system, and overhaul the
module and the cooling fan.
Check whether the maximum setting discharging protection temperature of
the battery is reasonable and check the protection parameters settings
through LCD or VISION APP. If the setting discharging protection
temperature is reasonable, completely power off the system, and overhaul
the module and the cooling fan.
Check whether the network cable connected by CBMS is loose or correctly
connected. If the connection is normal but the communication does not
work, please contact Vision.
Completely power off, and maintain the failure of communication between
modules.
1、Check whether the system works and whether there is blockage near
fans. If so, remove the foreign material. If it still cannot work, completely
power off the system and replace the fan.
