The selected charging profile is incompatible with the charger software. Update charger software or select a different charging profile.

CAN bus network error. Check the physical CAN connector, wiring, and other CAN modules for correct functioning.  Check termination is around 60 ohms.

Charger has received an error from the battery module or it is in a pre-operational state.

Internal supply rail error detected.  Remove AC and battery for minimum 30 seconds and retry charger. If the problem persists contact Support.

CAN heartbeats or PDOs were received and then timed out.  Check other CAN devices for function.

The charger configuration is asking for more voltage than the charger can deliver.  Charger reflash is required to correct this issue.

Charger is configured to with capacity scaling, but algorithm selected does not support this feature.  Select a scalable algorithm or reflash the charger.

The charger configuration is asking for voltage below 20% of the charger nominal.  Charger reflash is required to correct this issue.

Check if sensor is connected correctly.  Install a temperature sensor.  Change to an algorithm that does not require a temperature sensor.

Re-try CANOpen download or re-program using the USB

Inspect fan to make sure the power wires are connected and the fan blades are not obstructed by debris.

Inspect for objects on or near the button or damage to the button.  If alarm persists, replace charger.

Ensure that the fan is not stuck or drawing excess current, and that the correct fan part is installed. 

Software internal configuration error, ensure configuration settings are correct and reflash charger

Software internal configuration error, ensure configuration settings are correct and reflash charger

For Internal Use

Check the wiring harness to ensure only one charger has pins populated to be parallel charging master.

Make sure the right number of chargers are on the bus for this fixed configuration. Reset chargers to check if this alarm persists.

Check the configuration of all chargers that are sharing this bus.

Master device may be disconnected or powered down. Check wiring harness. Check configuration of devices. Reflash Master charger

Secondary chargers may be disconnected or powered down. Check the wiring and power to the secondary chargers. The alarm will automatically clear when the missing chargers come back online.

Check wiring harness and power to secondary chargers. Check to see if Secondary Chargers are issuing faults of their own.

Check the DC connections of all chargers and the battery.

Either they are disconnected from each other or there is an excessive series resistance which may result in cable overheating.  Check DC output wiring of the entire stack. The problem might be due to loosen or corroded connections in the cabling.

Check for alarms and faults reported by the secondary chargers.

Investigate and disconnect non-compliant device from the bus. Alternatively change the charger's configuration to exclude the conflicted address from its allowed range of addresses.

Charger is waiting for this message to start.  Check CAN cabling. Ensure nodes configured to send expected messages

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.

The charger compares the Battery 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.

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

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.

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.

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

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.

Monitored messages (Heartbeat, PGN, PDO) lost while charger output off. Check the networked CANbus device(s) for correct function and messages.
