To change information in a field, first use the arrow keys to move to and highlight
the field. Then press Enter, ↵. After the change is made, Enter (↵) must be pressed
again to confirm the change.
Once you begin modifying the digits in a field, you can move from digit to digit within
that field using the arrow keys.
However, to move to a different field, you must press Enter, ↵, after making your
last change to the field. The field is then highlighted. You can then use the arrow
keys to move to and highlight the next field you wish to modify.
Points are listed according to hardware type. In other words, all analog points
appear first, followed by digital points, and finally totalizer points.
There are three access levels that control operator access to XI581/2 information.
The access levels determine the information an operator can view and which tasks
an operator can perform.
Access level 1 is available to all operators and does not require a password. At level
1, you can view some, but not all, of the information programmed into the controller.
You cannot modify any data. Specifically, access level 1 allows you to view the
following:
• Time program information
• Point descriptions
• System clock
• Trend log
• Alarm information
• Buswide information
Passwords To operate at level 2 or 3, an operator must enter a password. Passwords are four
numerical characters and are controlled by the site administrator. The "Level 2/3
Password Entry" section explains how to enter your password.
Access level 2 allows you to view all information accessible to level-1 operators. In
addition, you can modify time programs, set the system clock, and view totalizer
information. You can also view and modify information in other controllers on the
same system bus.
Access level 3 allows you to perform all tasks accessible to level-1 and level-2
operators. In addition, you can:
• Modify point descriptions
• Reset totalizers
• Modify parameters
• Change setpoints
This access level should be reserved for only those users who are responsible and
competent in HVAC engineering, such as a commissioning engineer. This is to
avoid incorrect operation of the plant. This access level is required for setting the
access levels of the other users.
