Sensor Fault

What does 701 mean?

This status code indicates a fault with an external sensor connected to the Fronius Primo GEN24 208-240 inverter, such as a Smart Meter or a temperature sensor. This can be caused by wiring issues, a defective sensor, or incorrect sensor configuration.

• Issue with the wiring to the external sensor, such as a loose connection, break, or short circuit.
• The external sensor itself is defective and providing incorrect or no data.
• Incorrect configuration settings for the sensor within the inverter's parameters (e.g., sensor type, address).

Click steps to track your progress.

1. 1

   Check the wiring connecting the external sensor to the inverter for continuity, proper termination, and secure connections.

2. 2

   Verify the sensor configuration settings in the inverter's user interface, ensuring they match the installed sensor type and parameters.

3. 3

   If possible, test the sensor's functionality independently or temporarily replace it with a known good sensor to isolate the fault.

4. 4

   De-energize the inverter (switch off AC and DC disconnects), wait for 5 minutes, then re-energize to reset. If the message persists, the sensor may require replacement.
