information on another device. Therefore, a CCN module must
be attached when this screen is entered.
To attach any CCN device, highlight it using the
softkey and press the softkey. The message “UP-
LOADING TABLES, PLEASE WAIT” displays. The ICVC
then uploads the highlighted device or module. If the module
address cannot be found, the message “COMMUNICATION
FAILURE” appears. The ICVC then reverts back to the AT-
TACH TO DEVICE screen. Try another device or check the
address of the device that would not attach. The upload process
time for each CCN module is different. In general, the upload-
ing process takes 1 to 2 minutes. Before leaving the ATTACH
TO NETWORK DEVICE screen, select the local device. Oth-
erwise, the ICVC will be unable to display information on the
local chiller.
ATTACHING TO OTHER CCN MODULES — If the chill-
er ICVC has been connected to a CCN network or other PIC
controlled chillers through CCN wiring, the ICVC can be used
to view or change parameters on the other controllers. Other
PIC II chillers can be viewed and set points changed (if the oth-
er unit is in CCN control), if desired, from this particular ICVC
module.
If the module number is not valid, the “COMMUNICA-
TION FAILURE” message will show and a new address num-
ber must be entered or the wiring checked. If the module 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 ICVC is currently being shown, check the device name de-
scriptor on the upper left hand corner of the ICVC screen. See
Fig. 17.
When the CCN device has been viewed, the ATTACH TO
NETWORK DEVICE table should be used to attach to the PIC
that is on the chiller. Move to the ATTACH TO NETWORK
DEVICE table (LOCAL should be highlighted) and press
the softkey to upload the LOCAL device. The
ICVC for the 19XR chiller will be uploaded and default screen
will display.
NOTE: The ICVC will not automatically reattach to the local
module on the chiller. Press the softkey to attach to
the LOCAL device and view the chiller operation.
Service Operation — An overview of the tables and
screens available for the SERVICE function is shown in
Fig. 19.
TO ACCESS THE SERVICE SCREENS — When the SER-
VICE screens are accessed, a password must be entered.
1. From the main MENU screen, press the
softkey. The softkeys now correspond to the numerals
1, 2, 3, 4.
2. Press the four digits of the password, one at a time. An
asterisk (*) appears as each digit is entered
NOTE: The initial factory-set password is 1-1-1-1. If the
password is incorrect, an error message is displayed
If this occurs, return to Step 1 and try to access the SER-
VICE screens again. If the password is correct, the soft-
key labels change to:
NOTE: The SERVICE screen password can be changed
by entering the ICVC CONFIGURATION screen under
SERVICE menu. The password is located at the bottom
of the menu.
The ICVC screen displays the following list of available
SERVICE screens:
• Alarm History
• Alert History
• Control Test
• Control Algorithm Status
• Equipment Configuration
• ISM (Starter) Config Data
• Equipment Service
• Time and Date
• Attach to Network Device
• Log Out of Device
• ICVC Configuration
See Fig. 19 for additional screens and tables available from
the SERVICE screens listed above. Use the softkey to
return to the main MENU screen.
NOTE: To prevent unauthorized persons from accessing the
ICVC service screens, the ICVC automatically signs off and
password-protects itself if a key has not been pressed for 15
minutes. The sequence is as follows. Fifteen minutes after the
last key is pressed, the default screen displays, the ICVC
screen light goes out (analogous to a screen saver), and the
ICVC logs out of the password-protected SERVICE menu.
Other screen and menus, such as the STATUS screen can be
accessed without the password by pressing the appropriate
softkey.
TO LOG OUT OF NETWORK DEVICE — To access this
screen and log out of a network device, from the default ICVC
screen, press the and softkeys. Enter the
password and, from the SERVICE menu, highlight LOG OUT
OF NETWORK DEVICE and press the softkey.
The ICVC default screen will now be displayed.
TIME BROADCAST ENABLE — The first displayed line,
“Time Broadcast Enable,” in the SERVICE/EQUIPMENT
CONFIGURATION/BRODEF screen, is used to designate the
local chiller as the sole time broadcaster on a CCN network
(there may only be one). If there is no CCN network present
and/or there is no designated time broadcaster on the network,
current time and date, Daylight Saving Time (DST), and holi-
days as configured in the local chiller’s control will be applied.
If a network is present and one time broadcaster on the network
has been enabled, current time and date, DST, and holiday
schedules as configured in the controls of the designated time
broadcaster will be applied to all CCN devices (including chill-
ers) on the network.
HOLIDAY SCHEDULING (Fig. 29) — Up to 18 different
holidays can be defined for special schedule consideration.
There are two different screens to be configured. First, in the
SERVICE / EQUIPMENT CONFIGURATION / HOLIDAYS
screen, select the first unused holiday entry (HOLDY01S, for
example). As shown in Fig. 29, enter a number for Start Month
(1 = January, 2 = February, …, 12 = December), a number for
Start Day (1 - 31), and Duration in days (0 - 99). By default
there are no holidays set up. Second, in the occupancy Schedule
tables, specify and enable (by setting “X” under the “H” col-
umn) run time period(s) which will apply to all holidays. (Refer
to Fig. 20.) A run time period which is enabled for holidays may
be applied to one or more non-holiday days of the week as well.
