Event E009


Qualified person

Event message:

  • Lightning Arrester Alarm

Explanation:

The system has detected a fault indication signal from the surge protection device (SPD), which suggests that it may have been damaged by a flash of lightning or overvoltage and its protective function is no longer guaranteed.
The system has entered an error state and shut off the AC circuit breaker to prevent subsequent overvoltages from endangering the safety of the devices.

Corrective measures:

  • Immediately check the status window or indicator light of the surge protection device for alarm signals.

  • If the surge protection device has been confirmed as damaged:

    A specialist must replace it with a new module. Do not continue using a surge protection device that has triggered an alarm.

  • If the appearance of the surge protection device and its indicator light are normal:

    Check if the alarm signal wiring has any short circuits, breaks, or incorrect connections.

  • After replacing the module or fixing wiring problems, you must manually perform the Clear Errors operation in the battery pack control system interface for the system to function normally again.
