Check current access level by pressing 'Services' softkey, then 'Access Levels' to view active authorization level.

Log in with at least 'User' level credentials (password: typically SUNRISE for standard systems, or check machine documentation for custom passwords).

Incorrect password attempts may lock out the system temporarily. Verify password with supervisor before attempting.

Navigate back to the password deletion function and retry the operation with elevated privileges.

After successful password deletion, return to appropriate operational access level for normal machine operation.

Locate the physical key switch on the machine control panel (typically 4-position: 0, 1, 2, 3).

Only authorized personnel should have access to the key switch. Check company security protocols.

Turn key switch to position 2 or 3 to enable User/Manufacturer level access respectively.

Log in with appropriate password credentials for the desired access level (User, Service, or Manufacturer).

Perform the password deletion operation and return key switch to operational position (typically position 1).

Access machine data using Manufacturer level (key switch position 3, password: typically SUNRISE or OEM-specific).

Manufacturer level access allows modification of critical system parameters. Document all changes.

Navigate to Setting Data and check MD 9220-9227 (access level definitions) and SD 42700 (protection level settings) for correct configuration.

If password database appears corrupted, perform a system data backup, then restore default access settings from Siemens commissioning data or perform NCK reset of user data.

NCK reset will restore factory defaults for access settings. Ensure all custom passwords and settings are documented before proceeding.

Reboot the control system and verify access level functionality by testing login at each level (User, Service, Manufacturer).
