2.3 Access protection for data and settings
The ERZ2000-NG permits the entry and adjustment of all editable values. A descrip-
tion is provided in
chapter 2.2.1 Display.
All editable values are access-protected,
which prevents arbitrary changes. This access protection has different hierarchies
that are illustrated in the following figure:
Figure 31: Hierarchy of access protection
The lowest protection level applies with a closed calibration switch and without entry
of a protection code. With entry of the first protection code, you reach the next protec-
tion level and entry of the second protection enables access to the third protection
level.
These levels must be activated or deactivated by the user in order to make
changes.
The next protection level is subject to calibration protection and must only be opened
by authorized persons. The factory settings are also made in this level. There is also
a super user protection for the highest level. With higher protection level, all lower
protection levels are open. The following
Table 2: Access rights
explains the access
rights for the different protection levels.
