ATTACHING TO OTHER CCN MODULES Ð If the chiller PSIO has been connected to a CCN Network or other PIC controlled chillers through CCN wiring, the LID can be used to view or change parameters on the other controllers. Other PIC chillers can be viewed and set points changed (if the other unit is in CCN control), if desired from this particular LID module.

To view the other devices, move to the ATTACH TO NETWORK DEVICE table. Move the highlight bar to any

device number. Press the SELECT softkey to change the

bus number and address of the module to be viewed. Press EXIT softkey to move back to the ATTACH TO NET- WORK DEVICE table. If the module number is not valid, the ``COMMUNICATION FAILURE'' message will show and a new address number should be entered or the wiring checked. If the model is communicating properly, the ``UP- LOAD IN PROGRESS'' message will ¯ash and the new mod- ule can now be viewed.

Whenever there is a question regarding which module on the LID is currently being shown, check the device name descriptor on the upper left hand corner of the LID screen. See Fig. 22.

When the CCN device has been viewed, the ATTACH TO NETWORK DEVICE table should now be used to attach to the PIC that is on the chiller. Move to the ATTACH TO NETWORK DEVICE table and press the

ATTACH softkey to upload the LOCAL device. The PSIO

for the 19XL will now be uploaded.

NOTE: The LID will not automatically reattach to the PSIO

module on the chiller. Press the ATTACH softkey to attach

to LOCAL DEVICE and view the chiller PSIO.

Service Operation Ð An overview of the menu- driven programs available for Service Operation is shown in Fig. 17.

TO LOG ON

1.On the Menu screen, press SERVICE . The keys now correspond to the numerals 1, 2, 3, 4.

2.Press the four digits of your password, one at a time. An asterisk (*) appears as you enter each digit.

The menu bar (Next-Previous-Select-Exit) is displayed to indicate that you have successfully logged on.

If the password is entered incorrectly, an error message is displayed. If this occurs, return to Step 1 and try logging on again.

NOTE: The initial factory set password is 1-1-1-1.

TO LOG OFF Ð Access the Log Out of Device table of the Service menu in order to password-protect the Service menu. The LID will automatically sign off and password-protect itself if a key is not pressed for 15 minutes. The LID default screen is then displayed.

HOLIDAY SCHEDULING (Fig. 23) Ð The time schedules may be con®gured for special operation during a holiday period. When modifying a time period, the ``H'' at the end of the days of the week ®eld signi®es that the period is ap- plicable to a holiday. (See Fig. 18.)

The Broadcast function must be activated for the holidays con®gured in the Holidef tables to work properly. Access the Brodefs table in the Equipment Con®guration table and answer ``Yes'' to the activated function. However, when the chiller is connected to a CCN Network, only one chiller or CCN device can be con®gured to be the broadcast device. The controller that is con®gured to be the broadcaster is the device responsible for transmitting holiday, time, and daylight- savings dates throughout the network.

To view or change the holiday periods for up to 18 dif- ferent holidays, perform the following operation:

1.At the Menu screen, press SERVICE to access the Serv- ice menu.

2.If not logged on, follow the instructions for To Log On or To Log Off. Once logged on, press NEXT un- til Equipment Con®guration is highlighted.

3.Once Equipment Con®guration is highlighted, press SELECT to access.

4.Press NEXT until Holidef is highlighted. This is the Holiday De®nition table.

5.Press SELECT to enter the Data Table Select screen. This screen lists 18 holiday tables.
