Possible Causes
Vehicle drawing more current than configured limit, Incorrect maximum current setting in charger, Faulty current sensor (shunt or CT) inside Rolec unit, Loose or undersized supply cable causing voltage drop and mis‑reading
How to Fix / Troubleshooting
Safety first: Overcurrent can overheat wiring. Do not repeatedly reset without identifying the cause.
- Check charger rating: Confirm the Rolec charger’s rated current (e.g., 32 A) and ensure the vehicle is not configured to exceed this via smart charging apps.
- Verify installation settings: In installer mode, check that the maximum output current is set correctly for the supply and cable size.
- Inspect supply cable: With power isolated, check that the supply cable size matches Rolec’s requirements and that all terminations are tight.
- Monitor current draw (electrician only): Use a clamp meter to measure actual charging current. Compare with the charger’s configured limit.
- Sensor or PCB fault: If measured current is normal but E16 still occurs, the internal current sensor or its circuitry on the control PCB may be faulty and require replacement.
