8.2.6 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 (® ä 33).
Access authorization to parameters
User role
Operator
Maintenance
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 (e.g. "Format display").
For detailed information about parameters which can always be modified, refer to the
Operating Instructions for the device on the CD-ROM provided
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: Display/operation ® Access status display
8.2.7 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 (® ä 33).
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 F, the input prompt for the access code appears.
2. Enter the access code.
à The -symbol in front of the parameters disappears; all previously write-protected
parameters are now re-enabled.
8.2.8 Enabling and disabling the keypad lock
The keypad lock allows you to disable access to the entire operating menu via local operation.
Thus navigating through the operating menu or modifying the values of individual parameters
is no longer possible. Only the measured values on the operational display can be read off.
The keypad lock is enabled and disabled in the same way:
The user is in the operational display.
By simultaneously pressing the S + O + F keys.
