After this you can lock the user level by pressing the R

urn key while the lock is selected. If you need
to change the password, you can select the key icon again and give a new password. Please note that
in order to do this the user level whose password is being changed must be unlocked.
As mentioned above, the access level of the different user levels is indicated by the number of stars.
The required access level to change a parameter is indicated with a star (*) symbol if such is required.

breakers or other equipment.
•
Operator: Can view any menus and settings but cannot change any settings BUT can
operate breakers and other equipment.

Configurator: Can change most settings such as basic protection pick-up levels or time
delays, breaker control functions, signal descriptions etc. and can operate breakers
and other equipment.
