Info

IMPORTANT: The following notes apply to all Table 2 examples. 1. Only 12 lines of information appear on the chiller display 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. Press the NEXT softkey twice to page forward; press the PREVIOUS softkey twice to page back. 2. To access the information shown in Examples 10 through 22, enter your 4-digit password after pressing the SERVICE softkey. If no softkeys are pressed for 15 minutes, the CVC/ICVC automatically logs off (to prevent unrestricted access to PIC II controls) and reverts to the default screen. If this happens, you must re-enter your password to access the tables shown in Examples 10 through 22. 3. Terms in the Description column of these tables are listed as they appear on the chiller display screen. 4. The CVC/ICVC may be configured in English or Metric (SI) units using the CVC/ICVC CONFIGURATION screen. See the Service Operation section, page 45, for instructions on making this change. 5. The items in the Reference Point Name column do not appear on the chiller display screen. They are data or variable names used in CCN or Building Supervisor (BS) 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 information, see the 19XR CCN literature. Table 2 — CVC/ICVC Display Data EXAMPLE 1 — CHILLER DISPLAY DEFAULT SCREEN The following data is displayed in the Default screen. 22 6. Reference Point Names shown in these tables in all capital letters can be read by CCN and BS software. Of these capitalized names, those preceded by a dagger can also be changed (that is, written to) by the CCN, BS, and the CVC/ICVC. Capitalized Reference Point Names preceded by two asterisks can be changed only from the CVC/ICVC. Reference Point Names in lower case type can be viewed by CCN or BS only by viewing the whole table. 7. Alarms and Alerts: An asterisk in the far right field of a CVC/ ICVC status screen indicates that the chiller is in an alarm state; an exclamation point in the far right field of the CVC/ICVC 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 section, page 15.
