Access levels

Access to functions and machine data
The access concept controls access to functions and data areas. Access levels 0 to 7 are
available, where 0 represents the highest level and 7 the lowest level. Access levels 0 to 3 are
locked using a password and 4 to 7 using the appropriate key-operated switch.
Access level
The password remains valid until it is reset with the "Delete Password" softkey. The passwords
can be changed after activation.
If, for example, the passwords are no longer known, reinitialization (boot-up with "NCK default
data") must be carried out. This resets all passwords to the default (see table). A power-on reset
does not reset the password.
Key-operated switch
Access levels 4 to 7 require a corresponding key-operated switch setting on the machine
control panel. Three keys of different colors are provided for this purpose. Each of these keys
only provides access to certain areas.
Access level
The position of the key-operated switch can be processed by the PLC program, and
appropriately transferred to the NC/PLC interface .
