1. WARNING indications
| 1.1 Overheating motor | |
|
The Flex BP will switch to ECO mode to preserve the motor. Recommended actions: Stop riding as soon as possible and wait for the motor to cool down. |
|
| 1.2 Overheating Flex BP | |
|
The Flex BP will switch to ECO mode to preserve the BP. Recommended actions: Stop riding as soon as possible and wait for the Flex BP to cool down. |
|
| 1.3 Overheating CM | |
|
The Flex BP will switch to ECO mode to preserve the CM. Recommended actions: Stop riding as soon as possible and wait for the CM to cool down. |
|
| 1.4 Motor temperature sensor failure | |
|
The motor temp sensor is reporting invalid values, which indicates motor temperature sensor failure. Recommended actions: Contact support for further recommendations. |
|
| 1.5 CM temperature sensor failure | |
|
The CM temp sensor is reporting invalid values, which indicates CM temp sensor failure. Recommended actions: Contact support for further recommendations. |
|
| 1.6 Flex BP temperature sensor failure | |
|
The Flex BP temperature sensor is reporting invalid values, which indicates Flex BP temp sensor failure. Recommended actions: Contact support for further recommendations. |
|
| 1.7 Board orientation sensor failure | |
|
This indicates that the ”upside-down” board orientation sensor is faulty. This means the Flex HC will work even when the board is upside-down. Recommended actions: Stop operation and contact support for further actions. |
|
| 1.8 EEPROM failure | |
|
This indicates that data will not be saved after Flex BP power-off. User settings such as Flex HC mode may or may not be stored. The board can still operate. Recommended actions: Contact support for further recommendations |
|
| 1.9 Humidity sensor failure | |
|
This warning indicates the humidity sensor failed to initialise. The water inside the Flex BP may not be detected, which is potentially dangerous. Recommended actions: Stop operation and contact support for further actions. |
|
| 1.10 Unbalanced Flex BP (small diff.) | |
|
This warning indicates that there is a difference between Battery cell voltage levels. This state is prohibited by always letting the BP charge to 100% capacity (all GREEN lights). Recommended action: Leave on the charger (≈3 days continuous) until Flex BP is fully charged and no white indicator lights are turned on. If the warning is still active after a few balancing cycles, contact support and stop operating the Flex BP |
|
| 1.11 Unbalanced Flex BP (small diff.) | |
|
This warning indicates that there is a big difference between Battery cell voltage levels. This Flex BP state is prohibited by always letting the Flex BP charge to 100% capacity (all GREEN lights). Recommended action: Leave on the charger (≈7 days continuous) until Flex BP is fully charged and no white indicator lights are turned on. If the warning is still active after a few balancing cycles, contact support and stop operating the Flex BP |
|
2. ERROR indications
| 2.1 Contactor precharge error | |
|
This error indicates that the CM in the board has failing terminals inside it. Charging may still be possible, and the Flex BP may still work with other boards. Recommended actions: Contact support for further action. |
|
| 2.2 CM failure | |
|
This error indicates CM's failure, and riding is no longer possible with that specific board. The Flex BP will work with other boards and chargers. Recommended actions: Let the CM cool down and/or restart the Flex BP (disconnect/connect the PKL). If the error remains, contact support |
|
| 2.3 BMS failure | |
|
This error indicates that the BMS has not been communicating with the mainboard for over 6 seconds. Recommended action: Restart by disconnecting/connecting PKL. If the error remains, contact support. |
|
| 2.3 CAN bus failure | |
|
This error indicates that the communication inside the Flex BP or with the board is not working properly. Recommended action: Restart the Flex BP by disconnecting/connecting the PKL. If the error remains, contact support. |
|
| 2.4 Welded contactor | |
|
This error indicates that the contactor inside the Flex BP welds together due to the high current while opening. Mandatory actions: Don’t use, don’t charge, isolate the Flex BP at a safe location, and contact support. |
| 2.5 Overcharged / discharged BP | |
|
This error indicates that any cell row goes under or above the safe voltage values in any mode of operation: riding, idle mode, or charging. Mandatory actions: Don’t use, don’t charge, isolate the Flex BP at a safe location, and contact support. |
| 2.6 Humidity detected inside BP | |
|
This error indicates that humidity has been detected inside the Flex BP. Mandatory actions: Don’t use, don’t charge, isolate the Flex BP at a safe location, and contact support. |
| 2.6 Water detected inside BP | |
|
This error indicates that humidity has previously been detected inside the Flex BP and the information is now stored in the Flex BP’s memory. Mandatory actions: Don’t use, don’t charge, isolate the Flex BP at a safe location, and contact support.
