1. Check whether the battery string(s)
has been overdischarged or not via
multimeter.
2. Check the comm. cables between
master and slave BMS, make sure the
cable is 8PIN pin – pin CAT5 Ethernet
cable. If BMS and MBMS is communica-
tion via CANBUS (no Ethernet switch),
make sure the CANBUS physical length
is less than 12m. Restart the system.
3. Reverse sequence connect the
comm. cable between the BMSs and
change the ADD address settings.
Restart the system.
4. Change the BMS CMU or BMS.
5. If problem remain, contact Pylontech
service engineer.
