Access codes
To prevent unauthorized access to the control functions, there are provisions in the
software for assigning a Level 1 and/or Level 2 Access Code (up to six characters). A fixed
factory assigned Level 3 Access Code is required for changing calibration factors. When
Level 1 or Level 2 Access Codes are active, then an additional 30 Level Access Codes (up
to 15 characters) can be enabled as either Level 1 or Level 2. The Access Codes can be set
in the
Communication/HMI Menu
or from TCC600.
Level Access protection will be automatically reinstated when either of the following
conditions are met:
•
No HMI menu activity for a period of 15 minutes
•
The user exits to the top of the HMI menu for a period of greater than 10 seconds
3.2.3
Access levels
General access to read setpoints, to monitor status, to reset drag hand parameters and the
resettable operations counter do not require an Access Code.
The Level 1 Access Code, if set, is required to make setpoint changes. If the Level 1
Access Code is set to all zeros, this request for an Access Code will not be seen and
changes can be made without an Access Code. The default Level 1 Access Code is
000000.
The Level 2 Access Code, if set, is required to make changes to the configuration,
communication, and utilities. If the Level 2 Access Code is set to all zeros, this request for
an Access Code will not be seen and changes can be made without an Access Code. The
default Level 2 Access Code is 222222.
The Level 3 Access Code is required to make changes to calibration settings on the
control. Contact ABB Customer Service for TCC300 Level 3 Access Codes.
