101004

Press the RECALL key to clear the informational alarm from the display.

Verify which password level was changed by checking the %1 parameter in the alarm text (System=0, Manufacturer=1, Service=2, User=3).

Document the password change in the machine maintenance log with date, time, and person responsible for audit trail purposes.

Ensure the new password is securely stored according to company security protocols and communicated only to authorized personnel.

Never write passwords on or near the machine. Maintain password confidentiality according to ISO/IEC 27001 standards.

Immediately verify with all authorized personnel whether this was a planned password change. Check the exact time stamp of alarm 101004 in the alarm buffer.

Unauthorized password changes represent a serious security breach and may indicate compromised system access.

If unauthorized, immediately change the affected password level again using the next higher authority level (e.g., Manufacturer level can reset Service level passwords).

Review and restrict physical access to the machine control panel. Consider implementing additional access controls or surveillance if unauthorized access is confirmed.

Check the PLC program and machine parameters for any unauthorized modifications that may have occurred during the unauthorized access period.

Review critical safety parameters and backup settings before returning machine to production.

Confirm whether system maintenance, software updates, or control system restore operations were performed that triggered automatic password reset to default values.

If default passwords were restored, immediately change all access level passwords from Startup menu > Access Authorization > Passwords before returning machine to service.

Never operate with default factory passwords (System=SUNRISE, Manufacturer=EVENING, Service=CUSTOMER). This creates severe security vulnerabilities.

Verify control software version in Service menu > Version and document any system changes that occurred during the maintenance window.

Test all password levels to ensure proper access control functionality and that passwords were correctly set according to security policy.
