Current sensor calibration timeout

What does 314 mean?

This code indicates a timeout occurred during the current sensor calibration routine. This suggests an issue with the inverter's internal current measurement circuitry or its calibration process, leading to a short-term interruption.

• Malfunction of the internal current sensors or their associated electronics.
• Software or firmware issue affecting the calibration routine.
• Transient electrical noise interfering with calibration.

Click steps to track your progress.

1. 1

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

2. 2

   Perform an AC reset by cycling the automatic circuit breaker to restart the calibration sequence.

3. 3

   Check for strong electromagnetic interference in the vicinity of the inverter.
