8.4 Protecting settings from unauthorized access
8.4.1 Hardware locking
The device can be protected against unauthorized access by hardware locking. In the
locking and access concept, hardware locking always has top priority. The device is write-
protected if the keyhole symbol appears in the header of the measured value display. To
disable write protection, switch the write protection switch on the back of the display to
the "OFF" position (hardware write protection). → 19
By assigning a password for the Maintenance user role, it is possible to restrict access
authorization and protect the device against unauthorized access. See the Commissioning
