3.6. Warnings
When the BMS is working in a cluster or is controlling a device on CAN BUS 2, there are
2 additional warning flags the BMS will show.
- Warning flag 14. This warning indicates that one or more batteries in the cluster are
offline. More on this in section
4.4 Cluster Reset .
- Warning flag 23. This warning indicates that the battery has lost connection with the
controlled device connected on CAN BUS 2. The main causes of such an error are:
- Battery set to the incorrect controlled device
- Issue with the CAN BUS cable
- Incorrect terminations on the cable
- Controlled device communication settings incorrect
- Controlled device is off.
3.7. Cluster Reset
When a battery detects another battery, it will permanently remember it. If a battery
switches off or is removed from a cluster, the remaining batteries will show a warning
number 14 (displayed on each BMS indication LED). In case the battery has been
replaced in the cluster all batteries must be reset. A cluster reset can be done by one of
two methods
1. If the battery is connected to a logger, on the MyPower24 monitoring portal navigate
to ‘’My Devices’’, then select the battery you want to reset. Select the ‘’Settings
Installer’’ tab. Click on the ‘’Control’’ drop down and press the ‘’Reset Cluster Known
Devices’’ button. A blue balloon will appear to notify you of a successful reset. The
warning number 14 on the battery should now disappear.
2. The Multifunction push button on the battery can also be used to reset the known
devices on the cluster. Navigate to Sub Menu (Parameter 4), then Sub Parameter 4
(Reset Cluster) and set a value of 2.
Refer to page 14 of document ‘’ BMS-EX_Manual_CV_en1.1 ’’ for more
information on how to use the multi function push button.
