Figure 34: Hierarchy of access protection
The lowest protection level applies with a closed calibration switch and without en-
try of a protection code. With entry of the first protection code, you reach the next
protection level and entry of the second protection enables access to the third pro-
tection 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
