Engine shutdown with generic engine protection alarm; multiple parameter limits exceeded.

Safety: Do not repeatedly reset and restart without finding the root cause; this can destroy the engine.

• Review active and stored codes: Use the generator controller or Volvo Penta diagnostics to read all active faults. Identify which parameter triggered the shutdown.
• Address primary cause: If overheat, follow cooling system checks; if low oil pressure, follow lubrication checks; if overspeed, inspect governor and speed sensor.
• Inspect fluids and filters: Verify coolant and oil levels, and check condition of filters. Correct any deficiencies.
• Test run under supervision: After corrective actions, clear codes and run the generator while monitoring key parameters. If protection triggers again, stop and seek professional diagnosis.
