Possible Causes
Missing phase at charger input, Incorrect phase rotation (L1/L2/L3 swapped), Loose phase terminal, Faulty phase monitoring circuit on main board
How to Fix / Troubleshooting
Safety first: Only a qualified electrician should work on three‑phase supplies.
- Measure phases: Have an electrician verify that all three phases are present at the charger input and that line‑to‑line voltages are correct.
- Check rotation: If the charger requires a specific phase sequence, confirm that L1, L2, and L3 are connected as per the Garo wiring diagram.
- Tighten terminals: With power OFF, tighten all phase terminals and inspect for discoloration or heat damage.
- Board diagnostics: If supply is correct but E14 remains, the internal phase monitoring circuit on the main control board may be defective and should be replaced.
