Locking of the menu access
The menus are configured in a hierarchical
form and their locking level is indicated at
the first digit. The first line provides the
function ´Locked: MxTx´ for locking of
menus and keys. If the ´M´ is followed by a
number from 1 to 9, the menus starting from
the bottom line up to this level are locked
and cannot be selected, e.g. in case of ´M1´
the menus
´Device Configuration´
and
´Output Modules´
are locked, while ´M9´
indicates that all menus, except the
´Standard Display´
, are locked.
Locking of the operating keys
Depending on the menu the keys provide different functions. The following
functions can be locked using the corresponding locking level ´T´.

To also protect the locking configuration it is possible to enter a four-digit
password (see 5.3), for control purposes the display will only indicate ´****´.
The configuration will only be accessible if the same password is entered
again. However, in case of a reinitialisation the whole locking will also be
cleared (see 3.4).
