NOTE: When an alarm is detected, the LID default screen freezes (stops updating) at the time of alarm. The freeze en- ables the operator to view the chiller conditions at the time of the alarm. The status tables show the updated informa-

tion. Once all alarms have been cleared (by pressing the

RESET softkey), the default LID screen returns to normal

operation.

·Press NEXT or PREVIOUS to highlight the desired entry.

·Press SELECT to access the highlighted point.

·Press QUIT to leave the selected decision or ®eld with- out saving any changes.

LID DEFAULT SCREEN MENU ITEMS Ð To perform any of the operations described below, the PIC must be pow- ered up and have successfully completed its self test.

The default screen menu selection offers four options (STATUS, SCHEDULE, SETPOINT, and SERVICE). The STATUS menu allows viewing and limited calibration/ modi®cation of control points and sensors, relays and con- tacts, and the options board. The SCHEDULE menu allows viewing and modi®cation of the Local Control, CCN Con- trol, and Ice Build time schedules. Numerous set points in- cluding Base Demand Limit, LCW, ECW, and Ice Build can be adjusted under the SETPOINT menu. The SERVICE menu can be used to revise alarm history, control test, control al- gorithm status, equipment con®guration, equipment service, time and date, attach to network, log out of device, control- ler identi®cation, and LID con®gurations. Figures 15 and 16 provide additional information on the menu structure.

Press the MENU softkey to select from the 4 options.

To view or change parameters within any menu structure,

use the SELECT softkey to choose the desired table or

item. The softkey modi®cation choices displayed will de- pend on whether the selected item is a discrete point, ana- log point, or an override point. Press the softkey that cor- responds to your con®guration selection or press the

QUIT softkey. If the QUIT softkey is depressed, the

con®guration will not be modi®ed. Use the following soft- keys to access and select the desired section.

MENU STRUCTURE Ð To perform any of the operations described below, the PIC must be powered up and have suc- cessfully completed its self test.

·Press MENU to select from the four available options.

·Press the softkey that corresponds to the desired menu structure.

·Or, press ENTER to leave the selected decision or ®eld and save changes.

TO VIEW OR CHANGE POINT STATUS (Fig. 13) Ð Point Status is the actual value of all of the temperatures, pres- sures, relays, and actuators sensed and controlled by the PIC.

1.On the Menu screen, press STATUS to view the list of Point Status tables.

2.Press NEXT or PREVIOUS to highlight the desired status table. The list of tables is:

·STATUS01 Ð Status of control points and sensors

·STATUS02 Ð Status of relays and contacts

·STATUS03 Ð Status of both optional 8-input modules and sensors

·STATUS04 Ð Gear oil temperature and pressure
