CC%2 alarm self-test Addr:%4, Dev:%5, Actl:%6, Noml: %7

What does 231-E024 mean?

This error indicates that an internal process error was detected during a self-test routine within a component or module of the Heidenhain TNC CNC Controller. The error message provides diagnostic parameters (Address, Device, Actual value, Nominal value) that point to the specific location and nature of the internal fault, suggesting a potential hardware or firmware issue affecting system integrity.

• An internal hardware fault within the specific device identified by the Address (Addr) and Device (Dev) parameters.
• A firmware bug or data corruption affecting the self-test routine of the identified module.
• A temporary transient condition or instability in the power supply leading to an incorrect self-test result.

Click steps to track your progress.

1. 1

   Record the full error message, including Addr, Dev, Actl, and Noml values, as these parameters are crucial for detailed diagnosis by Heidenhain support.

2. 2

   Perform a controlled power cycle of the Heidenhain TNC CNC Controller and the affected peripheral device to clear any transient internal states.

3. 3

   Verify the stability and correct voltage levels of the power supply to the controller and all associated modules to rule out power-related issues.

4. 4

   Check for any available firmware updates for the identified device or the TNC controller, as the error might be resolved in a newer version.

5. 5

   If the error persists, contact a Heidenhain service agency, providing all collected diagnostic parameters for expert analysis and potential hardware replacement.
