HEIDENHAIN 330-00C9 - Error during activation of an FS configuration
HEIDENHAIN alarm 330-00C9 occurs when safety-critical machine parameters related to functional safety monitoring are modified after the FS (Functional Safety) self-test has already begun. The TNC system prevents changes to brake test timing and self-test intervals during active safety validation to maintain system integrity.

HEIDENHAIN 330-00C9 - Error during activation of an FS configuration
Error during activation of an FS configuration
The safety self-test detected an error. A required signal was not properly set or detected by the HSCI component.
Root Cause Summary
HEIDENHAIN alarm 330-00C9 occurs when safety-critical machine parameters related to functional safety monitoring are modified after the FS (Functional Safety) self-test has already begun. The TNC system prevents changes to brake test timing and self-test intervals during active safety validation to maintain system integrity.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check FS self-test status
Press MOD key, select 'Machine' menu, navigate to 'Functional Safety' to verify if self-test is currently active or pending.
The FS status display shows real-time self-test progress and remaining time
- 2
Wait for self-test completion
Allow the current FS self-test cycle to complete fully before attempting any parameter changes. Monitor the progress indicator in the FS status screen.
Never interrupt an active safety self-test as this can compromise machine safety certification
- 3
Modify parameters in safe window
After self-test completion, access Setup menu > Machine Parameters > Safety Parameters (MP7500-7599) to make required timing adjustments.
Changes to safety parameters require a complete power cycle and new self-test to take effect
- 4
Initiate new self-test cycle
Power cycle the TNC system and allow the new FS self-test to run with updated parameters to clear the alarm condition.
Call a technician if:
- ·FS system status remains failed after multiple power cycles
- ·Safety certificate validation required
- ·Brake test hardware malfunction suspected
Prevention
- Always check FS system status before modifying safety parameters
- Schedule safety parameter changes during planned maintenance windows
- Document all safety parameter changes with timestamps
- Verify FS self-test completion before making configuration changes
Common Mistakes
- Changing multiple safety parameters simultaneously
- Modifying parameters during active brake tests
- Not waiting for FS system initialization after power-up
- Interrupting self-test cycles to make urgent parameter changes
