Table 2 — 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. Pressthe NEXT
or PREVIOUS softkey tohighlight 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 arepressed for 15 minutes,the LID automaticallylogs 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 configured in English or Metric (SI) units using
the LIDCONFIGURATIONscreen. Seethe ServiceOperation 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 field of a LID status
screen
indicates that the chiller is in an alarm state; an exclama-
tion point in the far right field 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.
