Verify with machine operators or maintenance staff that password configuration was intentional and authorized.

Document which protection level (%1 parameter shows: 1=System, 2=Manufacturer, 3=Service, 4=User) had the password set in the machine logbook.

Ensure the new password is stored securely according to company security protocols and access control procedures.

Loss of passwords, especially System or Manufacturer level, may require factory intervention to reset.

Acknowledge the alarm on the HMI - no further action required as this is informational only.

Verify this alarm appeared during expected commissioning, software upgrade, or CF card restoration activities.

Cross-reference with NCK alarm buffer (Diagnostics > Alarms > NCK) to confirm timestamp matches the configuration activity.

Test access levels by logging in with the new password to verify correct protection level functionality.

Update machine documentation and password management system with the new security configuration.

Ensure backup documentation exists for all protection level passwords before leaving the site.

Review the NCK logbook immediately (Diagnostics > Logbook) to identify timestamp and determine which user session made the change.

Unauthorized password changes may indicate a security breach requiring immediate action.

Check if higher-level passwords (System/Manufacturer) are still valid by attempting login - unauthorized changes typically affect lower levels first.

If unauthorized change is confirmed, immediately reset passwords using higher-level access credentials (System or Manufacturer level).

Implement additional access controls, review physical HMI access security, and document incident per company security protocols.
