Power unit: Air intake overtemperature

Siemens · DCM

What does F30035 mean?

The temperature at the power unit's air intake has surpassed its permissible limit, typically 55°C for air-cooled units. This is often caused by high ambient temperatures or a malfunctioning cooling fan. Continued operation above this limit can lead to hardware damage and system shutdown.

Complete Troubleshooting Guide

  1. 1

    Ensure the cooling fan is running, its elements are free of obstructions, and it operates in the correct direction.

  2. 2

    Verify the ambient temperature is within the specified operating range for the power unit.

  3. 3

    Check that air filters are clean and air pathways are not blocked.
