Power unit: Air intake overtemperature

What does F30035 mean?

The air intake temperature in the power unit has exceeded the permissible limit, typically 55 °C. This condition signifies critical overheating of the incoming air, often caused by high ambient temperatures, insufficient airflow, or a fan failure. This fault forces an OFF1 or OFF2 reaction, stopping the drive, and cannot be acknowledged until the temperature falls below the alarm threshold of A05002.

Complete Troubleshooting Guide

1. 1

   Check the ambient temperature to ensure it is within the permissible operating range.

2. 2

   Verify that the cooling fan(s) are running correctly and inspect fan elements for blockages or damage.

3. 3

   Ensure sufficient airflow around the unit and that air vents are clear.
