CHANGING REFRIGERANT TYPES — To select refrig-

erant type, go to the Control Test table. Whenever the re-

frigerant type is changed, the ATTACH TO NETWORK

DEVICE table must be used. After changing the refrigerant

type in the Control Test table, move to the ATTACH TO NET-

WORK DEVICE table. Make sure the highlight bar is lo-

cated on the LOCAL selection. Press the ATTACH softkey.

The information in the PSIO module will now be uploaded.

The default screen will appear. The new refrigerant type change

for the controller is complete.

NOTE: Refrigerant type can be changed on Frame 4 ma-

chines only.

ATTACHING TO OTHER CCN MODULES — If the ma-

chine 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 machines can be viewed and set points changed

(if the other unit is in CCN control), if desired from this par-

ticular LID module.

To view the other devices, move to the ATTACH TO NET-

WORK DEVICE table. Move the highlight bar to any de-

vice number. Press SELECT softkey to change the bus num-

ber and address of the module to be viewed. Press EXIT softkey

to move back to the ATTACH TO NETWORK DEVICE table.

If the module number is not valid, the ‘‘COMMUNICA-

TION FAILURE’’message will show and a new address num-

ber should be entered or the wiring checked. If the model is

communicating properly, the ‘‘UPLOAD IN PROGRESS’’

message will ﬂash and the new module 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. 26.

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 machine. Move to the

ATTACH TO NETWORK DEVICE table and press the

ATTACH softkey to upload the LOCAL device. The PSIO

for the 23XL will now be uploaded.

NOTE: The LID will not automatically re-attach to the PSIO

module on the machine. Press the ATTACH softkey to at-

tach to LOCAL DEVICE and view the machine PSIO.
