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 →  82.

Access authorization to parameters: "Operator" user role

Access Code Status
An access code has not yet been defined
(factory setting).
After an access code has been defined.
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).

Access authorization to parameters: "Maintenance" user role

Access Code Status
An access code has not yet been defined
(factory setting).
After an access code has been defined.
1) If an incorrect access code is entered, the user obtains the access rights of the "Operator" user role.
The user role with which the user is currently logged on is indicated by the
Access status parameter. Navigation path: Operation → Access status.
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 local operation →  82.
Parameter write protection via local operation can be disabled by entering the
user-specific access code in the Enter access code parameter 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.

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
