9.1. LED indications, warning, alarm and error codes
LEDs
The Lynx Smart BMS NG is equipped with two LEDs, the Bluetooth LED and the Status LED. These LEDs will indicate the operation mode and the fault mode in case there is a fault.
Bluetooth LED | Description |
|---|---|
Off | No system power or Bluetooth is disabled in the VictronConnect app. Bluetooth can be disabled in both VictronConnect and a GX device but only enabled from a GX device. |
Blue on | A Bluetooth device is connected to the Lynx Smart BMS NG |
Blue flashing | Bluetooth is active, but no device is connected |
Blue flashing at 3 seconds interval | The Lynx Smart BMS NG is in OFF mode but is still accessible via Bluetooth |
Status LED | Description |
|---|---|
Off | The Lynx Smart BMS NG is in OFF mode |
Orange on | Initialising or shutdown |
Orange blinking | Delayed shutdown due to cooling down the pre-charge circuit |
Green on | Running, the contactor is closed |
Green blinking | Pre-charging |
Green flashing at 3 seconds interval | The Lynx Smart BMS NG is in Standby mode |
Green and red alternating | System in bootloader mode (updating firmware) |

Warning, alarm and error codes
|
|
The following tables list all warning, alarm and error codes:
Warning codes
VictronConnect warning code | GX device warning code | Message | Instructions / Remarks |
|---|---|---|---|
W-B01 | Low cell voltage | Low cell voltage | Charge the battery or reduce the load to prevent an imminent system shutdown. |
W-B02 | #105 or #106 | High current | Reduce the current to prevent an imminent system shutdown. Do this by reducing the load or by turning loads off. |
W-B03 | #101 | High BMS temperature | Check the ambient temperature and check if the BMS fans are running. If the fans are running, reduce the ambient temperature. If the fans are not running, contact your Victron dealer. |
W-B04 | #112 | Warning bad contactor | Reduce the current to prevent an imminent system shutdown. Do this by reducing the load or by turning loads off. Contact your Victron dealer. |
W-B06 | - | Load will disconnect | The loads will be turned off in 30 seconds if fault is not resolved. For example low battery voltage. This warning is always in combined the reason why the load will disconnect. The loads are turned off via the ATD contact and/or via the GX device. |
W-B07 | - | Low SoC | Charge battery or reduce load to prevent imminent system shutdown. |
W-D01 | #221 | Communication with distributor A lost | Check the cable between BMS and Distributor. |
W-D02 | #222 | Communication with distributor B lost | Check the cable between BMS and Distributor. |
W-D03 | #223 | Communication with distributor C lost | Check the cable between BMS and Distributor. |
W-D04 | #224 | Communication with distributor D lost | Check the cable between BMS and Distributor. |
Alarm codes
VictronConnect alarm code | GX device alarm code | Message | Instructions / Remarks |
|---|---|---|---|
A-B01 | #103 | Low cell voltage | Charge battery. The system will turn the loads back on when the battery is sufficiently charged. |
A-B02 | #105 or #106 | High current | Reduce charging current or turn off some loads. The system will try to re-enable chargers or loads in 5 minutes. |
A-B06 | - | Load disconnected | The loads have been turned off via the ATD contact and/or via the GX device. Resolve this alarm by charging the battery. If not resolved, eventually the contactor will open and the DC system will be disconnected. |
A-B07 | - | Low SoC | Charge battery. The system will turn the loads back on when the battery is sufficiently charged. |
Error codes
VictronConnect error code | GX device error code | Message | Instructions / Remarks |
|---|---|---|---|
E-B09 | #09 | Battery voltage not allowed | The battery voltage is too high or too low. Check the battery voltage and check the battery settings in the VictronConnect app. This error occurs when the battery voltage is outside all system voltage ranges (9V > Vbat > 60V) |
E-B11 | #11 | Hardware error | Contact your Victron dealer. |
E-B25 | #25 | Pre-charge error | The load resistance is too low to pre-charge the loads. Disconnect or reduce some DC loads. |
E-B26 | #26 | Contactor error | Contact your Victron dealer. |
E-B34 | #34 | Wrong system voltage | Check battery voltage settings in the VictronConnect app. |
E-B35 | #35 | Pre-charge timeout | The load capacity is too high to pre-charge. Disconnect some DC loads. |
E-B36 | #36 | ATC/ATD failure | Check ATC/ATD wiring and make sure that all loads and chargers are controlled by ATC or ATD. |
E-B119 | #119 | Settings data lost | Settings data is corrupt. Go to the settings page and reset to defaults. |
