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 →  145.

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 local operation →  145.
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.
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.
