Table 2 Ð LID Display Data

NOTES:

IMPORTANT: The following notes apply to all Table 2 examples.

1.Only 12 lines of information appear on the LID screen at any one time. Press the NEXT or PREVIOUS softkey to highlight a point or to view items below or above the current screen. If you have a chiller with a backlit LID, press the NEXT softkey twice to page forward; press the PREVIOUS softkey twice to page back.

2.To access the information shown in Examples 6 through 14, enter your 4-digit password after pressing the SERVICE softkey. If no

softkeys are pressed for 15 minutes, the LID automatically logs off (to prevent unrestricted access to PIC controls) and reverts to the default screen. If this happens, you must reenter your password to access the tables shown in Examples 6 through 14.

3.Terms in the Description column of these tables are listed as they appear on the LID screen.

4.The LID may be con®gured in English or Metric (SI) units using the LID CONFIGURATION screen. See the Service Operation sec- tion, page 42, for instructions on making this change.

5.The items in the Reference Point Name column do not appear on the LID screen. They are data or variable names used in CCN or Building Supervisor software. They are listed in these tables as a convenience to the operator if it is necessary to cross reference CCN/BS documentation or use CCN/BS programs. For more in- formation, see the 17EX CCN literature.

6.Reference Point Names shown in these tables in all capital letters can be read by CCN and Building Supervisor software. Of these capitalized names, those preceded by an asterisk can also be changed (that is, written to) by the CCN, Building Supervisor soft- ware and the LID. Capitalized Reference Point Names preceded by two asterisks can be changed only from the LID. Reference Point Names in lower case type can be viewed by CCN or Build- ing Supervisor software only by viewing the whole table.

7.Alarms and Alerts: An asterisk in the far right ®eld of a LID status screen indicates that the chiller is in an alarm state; an exclama- tion point in the far right ®eld of the LID screen indicates an alert state. The asterisk (or exclamation point) indicates that the value on that line has exceeded (or is approaching) a limit. For more information on alarms and alerts, see the Alarms and Alerts sec- tion, page 16.
