Product Series: RQ |
Article No: FAQ102 |
This article lists fault (F_ _ _ ) and error (E_ _ _ ) codes on the chargers with the standard RQ Alarm Mapping. Note that not all will be displayed on chargers with a user interface, there might be other errors being reported over CAN and logged. If your unit is not functioning and nothing is being indicated or logged, check and cycle both AC and DC. If this condition persists, replace the charger.
All of the error codes will be shown with a series of red flashes (from 1 up to 9 flashes) on the fault status indicator LED, as seen in the illustration below. Except for the AC input errors, which will be shown with flashing blue on the AC power indicator.
The number of red flashes represents a group of errors. These errors would be the same error codes seen in the IC/RC/ICL series chargers.
1 and 2 Red Flashes | Battery Related
4 Red Flashes | CANbus/Application Compatibility
5 Red Flashes | CAN Communication
7 Red Flashes | Battery Temp. Sensor
8 Red Flashes | Intentionally not used
9 Red Flashes | Software Configuration

| Error | Description | Troubleshooting and/or Recommended Actions |
| E023 | AC Voltage High | AC voltage is too high. Connect charger to an AC source that provides stable AC between 85 - 270 VAC / 45-65 Hz. This error will automatically clear once the condition has been corrected. |
| E025 | AC Voltage Unstable and Low | AC source is unstable. Could be caused by an undersized generator and/or severely undersized/long AC cables. Connect the charger to an AC source that is stable and between 85 - 270 VAC / 45-65 Hz. This error will automatically clear once the condition has been corrected. |
1 and 2 Red Flashes | Battery Related
| Error | Description | Troubleshooting and/or Recommended Actions |

| E013 | Charger Output Current Not Accepted | Battery voltage is detected, but the charger is unable to output current. This is normally caused by an electrical device connected between the charger and the battery, which passes through voltage but not current. Poor connections can also cause this. Ensure the charger is properly connected to approved equipment. This error will automatically clear once the charger is reset by cycling DC or AC. |
| E022 | Low Battery Voltage Error While Charging | Battery Voltage is too low as detected by the algorithm. Check the battery voltage and cable connections. This error will automatically clear once the condition has been corrected. |

3 Red Flashes | Timers
| Error | Description | Troubleshooting and/or Recommended Actions |
| E003 | Charge Timeout | Charge Timeout caused by the battery pack not reaching the required voltage within the safe time limit. |
| E007 | Charge Amp-Hour Limit Exceeded | Safety limit exceeded. Possible causes: Poor battery health. Very deeply discharged battery. Poorly connected battery. High parasitic loads on battery while charging. Possible solutions: Replace the battery pack. Check DC connections. Disconnect parasitic loads. This error will automatically clear once the charger is reset by cycling DC. |
4 Red Flashes | CANbus/Application Compatibility
| Error | Description | Troubleshooting and/or Recommended Actions |
| E004 | Battery Defective | Battery could not be trickle charged up to the minimum voltage. Check for shorted or damaged cells. Check battery pack voltage matches charger voltage.

| E044 | CANopen PDO Sequence Count Not Changing | |
| E046 | CAN - Invalid PDO Length | Power cycle all CAN nodes and charger. Error will clear once sequence counter updates. Reflash charger if this persists. |
| E061 | CAN Battery Current Report Mismatch | The charger compares the Battery written current with its output current. Check that the right current is being sent to the charger. Check if the output cable has a parallel branch. |
| E062 | CAN Battery Voltage Report Mismatch | The charger compares the battery's written voltage with its output voltage. Check that the correct voltage is being sent to the charger. Check that the output cable resistance matches the charger setting. Check for other sources of voltage drop. |
5 Red Flashes | CAN Communication
| Error | Description | Troubleshooting and/or Recommended Actions |
| E029 | CAN Bus Physical Layer Error | CAN bus network error. Check the physical CAN connector, wiring, and other CAN modules for correct functioning. Check termination is around 60 ohms. |

| E060 | CAN Communications Never Received | The charger is waiting for this message to start. Check CAN cabling. Ensure nodes are configured to send expected messages |
| E064 | J1939 Address - Charger Failed to Claim | The most likely cause of this problem is that two or more chargers, configured for the same fixed address, have been connected to the same bus in error. Alternatively there could be a configuration issue and the addresses available to the charger are already being used by other customer devices on the bus. |
| E065 | J1939 Address - Other Device Failed to Claim | Read SPN 611 from the charger(s) that has raised this alarm. This will contain the 64-bit J1939 "Name" of the device that could not claim its address (see J1939-81 Network Management, Feb 2016, Section 4.2.1 ). |
| E067 | CAN Physical Layer Error - Before Messages Received | CANbus network error. Check the physical CAN connector, electrical bus conditions and other CAN modules for correct functioning. For example check termination resistance is approximately 60ohms. |
| E068 | Missing CAN Messages While Not Charging | Monitored messages (Heartbeat, PGN, PDO) lost while charger output off. Check the networked CANbus device(s) for correct function and messages. |
