Danfoss Control C.2 Operator's Manual page 49

User names
User names and the associated passwords are created or deleted by
the operator. The user name currently logged on cannot be deleted. If
the current user name is to be deleted, it is necessary to log on an-
other user first.
In the factory, the standard user "user" is installed as an "administra-
tor". The standard user can only be deleted if there is at least one
other user name available on the administrator level.
The number of users is only restricted by the storage space of the
control.
User levels
The user levels can be used to assign user names with different
rights with regard to machine operation. In total, up to ten different
user levels can be set up. The user level "administrator" cannot be
deleted or changed.
At the factory, one administrator level is set up. The machine settings
can only be called up by user names of the administrator level.
In the factory settings, the user levels "0 – 8" and "operator" have the
same rights. These user levels are able to operate the full scope of
functions on the machine but are not able to call up the machine set-
tings.
The rights of the user levels can be programmed individually for an
extra fee. Contact the manufacturer for this purpose.
The Administrator password may be required for repairs. If login
data are no longer available, the user administration must be re-
stored by the manufacturer subject to a charge.
