Error when recording measuring signal

What does 458 mean?

This code indicates an error during the recording of a general measuring signal within the inverter. This suggests an issue with an internal sensor or its data acquisition pathway, preventing accurate measurements crucial for energy feeding.

• Faulty internal sensor (e.g., current, voltage, temperature sensor).
• Disruption in the analog-to-digital conversion process.
• Software error in data acquisition routines.

Click steps to track your progress.

1. 1

   If the status code is displayed continuously, notify a Fronius-trained service engineer for sensor diagnosis.

2. 2

   Perform an AC reset by cycling the automatic circuit breaker to re-initialize the measurement system.

3. 3

   Check internal signal integrity of sensor connections.
