OCPP Faulted triage map

Field reference for technicians. Not an OEM manual.

Scope

• Map Faulted vs Unavailable vs SuspendedEV
• Heartbeat vs Authorize vs StartTransaction failures
• When the problem is CSMS vs charger vs site network

Triage order

1. Confirm presentation (display, LEDs, OCPP StatusNotification, CSMS).
2. Separate vehicle vs EVSE vs site (power, network, payment).
3. Check recent changes: firmware, cable swap, SIM, LMS config.
4. Apply LOTO before opening energized sections.
5. Validate with a known-good session and document firmware/part lots.

Safety

High-voltage DC and AC mains can kill. Use PPE, verify zero energy, and follow NFPA 70E / site rules. Arcbound Field content is educational reference only.
