Redarc BMS1215S2 User Manual

3 USER GUIDE
3.4 Troubleshooting
The Redarc BMS is one of the most advanced Battery Management Systems on
the market. It has been designed to detect and advise the operator of a variety
of fault conditions and will terminate the charging cycle immediately should a
critical fault be detected. This ensures that it will not attempt to charge a faulty
battery, which protects the BMS, house battery and most importantly the user.
The Remote Display is used to inform the user of the nature of the problem
whenever possible. These indicators should be used to diagnose, and if possible
correct any faults that may occur. If after attempting to rectify the situation,
a fault still occurs, please send the unit back to Redarc for diagnosis. When
attempting to diagnose a fault, cabling should be over-rated and all components,
including all input sources and house battery should be connected as close as
possible to the BMS.
BMS FAULT MESSAGE CAUSE ACTION
