8.3.10 User roles and related access authorization
The two user roles "Operator" and "Maintenance" have different write access to the
parameters if the customer defines a user-specific access code. This protects the device
configuration via the local display from unauthorized access .

1) Despite the defined access code, certain parameters can always be modified and thus are excepted from
the write protection, as they do not affect the measurement. Refer to the "Write protection via access code"
section
If an incorrect access code is entered, the user obtains the access rights of the "Operator"
role.
The user role with which the user is currently logged on is indicated by the Access
status display parameter. Navigation path: Operation → Access status display
8.3.11 Disabling write protection via access code
If the -symbol appears on the local display in front of a parameter, the parameter is
write-protected by a user-specific access code and its value cannot be changed at the
moment using the local display .
The locking of the write access via local operation can be disabled by entering the
customer-defined access code via the respective access option.
1. After you press , the input prompt for the access code appears.
2. Enter the access code.
 The -symbol in front of the parameters disappears; all previously write-
protected parameters are now re-enabled.
8.3.12 Enabling and disabling the keypad lock
The keypad lock makes it possible to block access to the entire operating menu via local
operation. As a result, it is no longer possible to navigate through the operating menu or
change the values of individual parameters. Users can only read the measured values on
the operational display.
