Description
Password level
The password level displays additional menus and data-
points for configuring and commissioning the bus opera-
tor unit. The password level is protected by a password to
prevent unauthorized access. The unit comes standard
with number “7” as the password.
From this level, the password level of the bus users
cannot be accessed; the setting only acts locally.
With the exception of the info level, operation is structured in the form of a menu tree.
Individual menus or operating lines are enabled depending on the access level. The
higher access level always displays all menus and operating lines of lower access
levels also; the password level shows the entire menu tree. The active level is indicated
by an appropriate symbol at top left.
Using the INFO button, explanations relating to the menus and the individual datapoints
can be displayed. The information is displayed as long as the button is kept depressed.
