Classic EV Charger Fault Codes and LED Indicators

Decode fault codes and LED signals to troubleshoot issues efficiently for the Classic EV Charger.

Updated today

Your Emporia Classic EV Charger uses orange LED flashing patterns to indicate faults detected during self-checks. Understanding these patterns helps troubleshoot issues quickly.

Understanding LED Patterns

Fault codes display as "slow flash number / fast flash number" (e.g., "1 slow / 2 fast" means one slow orange flash followed by two fast orange flashes).

  • Slow flash: 0.66Hz frequency with 66% duty cycle

  • Fast flash: 2Hz frequency (twice per second) with 50% duty cycle
