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 CCN mod-
ule the LID is currently showing, check the device name de-
scriptor on the upper left hand corner of the LID screen. See
Fig. 20.
When the CCN device has been viewed, the ATTACH TO
NETWORK DEVICE table should now be used to
attach to the PSIO 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 19EF 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.
Service Operation —
An overview of the menu-
driven programs available for Service Operation is shown in
Fig. 14.
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 — 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. 21) — The time schedules
may be configured for special operation during a holiday pe-
riod. When modifying a time period, the ‘‘H’’ at the end of
the days of the week field signifies that the period is appli-
cable to a holiday. (See Fig. 15.)
The Broadcast function must be activated for the holidays
configured in the Holidef tables to work properly. Access
the Brodefs table in the Equipment Configuration table and
answer ‘‘Yes’’ to the activated function. However, when the
machine is connected to a CCN Network, only one machine
or CCN device can be configured to be the broadcast device.
The controller that is configured 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 Configuration is highlighted.
3. Once Equipment Configuration is highlighted, press
SELECT to access.
4. Press NEXT until Holidef is highlighted. This is
the Holiday Definition table.
5. Press SELECT to enter the Data Table Select screen.
This screen lists 18 holiday tables.
