AC current sensor error

Hva betyr 315 ?

This code indicates an error with the AC current sensor. This sensor is crucial for measuring the current being fed into the grid and for protective functions. An error in this sensor causes a short-term interruption in energy feeding.

• Malfunction of the internal AC current sensor hardware.
• Disconnection or damage to the AC current sensor wiring.
• Fault in the associated signal processing circuitry.
