Possible Causes
Supply frequency outside allowed range (e.g., not 50/60 Hz), Generator or inverter-based supply instability, Faulty frequency sensing circuit on control board
How to Fix / Troubleshooting
Note: ABB chargers monitor grid frequency to ensure stable operation.
- Check supply source: If the charger is powered from a generator or inverter, verify that it provides a stable 50/60 Hz output within ABB’s specified tolerance.
- Measure frequency: Use a multimeter with frequency measurement to confirm the actual line frequency at the charger input.
- Test on utility power: If possible, temporarily connect the charger to a standard utility-fed circuit to see if E013 disappears.
- Control board diagnosis: If frequency is within spec but E013 persists, the frequency sensing circuit on the control board may be defective and require board replacement.
