IC/RC/ICL Series Faults and Error Codes

This article lists fault (Fxxx) and error (Exxx) codes on these chargers.  Most of these will be reported over CAN and logged.  Not all will be displayed on chargers with a user interface.  If a unit is not functioning and nothing is indicated or logged, check and cycle both AC and DC.  If this condition persists, replace the charger.

Troubleshooting and/or Recommended Actions

Alarm E001 High Battery Voltage Error

Battery Voltage is too high to start charge. Check the battery voltage and cable connections. Check battery size and condition. This error will automatically clear once the condition has been corrected.

Alarm E002 Low Battery Voltage Error

Battery Voltage is too low to start charge. Check the battery voltage and cable connections.  Check battery size and condition. This error will automatically clear once the condition has been corrected.

Alarm E003 Charge Timeout

Charge Timeout caused by battery pack not reaching required voltage within safe time limit.

Possible causes: Charger output reduced due to high temperatures or low AC voltage. Poor battery health. Very deeply discharged battery. Poorly connected battery. Extra loads.  Battery too large for algorithm selected.

Possible solutions: Improve cooling air flow. Check for low AC voltage. Replace battery pack. Check DC connections. This error will automatically clear once the charger is reset by cycling DC.

Alarm 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.  Replace battery pack. Check DC connections. This error will automatically clear once the charger is reset by cycling DC.

Alarm E063 Stackable Charging - Incompatible Secondary Charger(s)

Query the master to identify which secondary has the bad configuration or interface version.

Alarm 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.

Alarm 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 ). If this device is another Delta-Q charger (manufacturer code 800, function Id 141) and this is a stackable charging system then possible causes include: i) Incorrectly configured chargers

ii ) Address conflicts exist between the charger and other devices on the bus iii ) Master/Secondary wiring fault. The alarm will be cleared on charger reset - but may immediately trigger if the address conflict persists.

Alarm E066 Battery Voltage Higher Than Configured Maximum

Check if the charger is connected to the right battery, or the maximum voltage configured is too low.

Alarm 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 approx. 60ohms.

Alarm 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.
