Software Configuration - Carrier 19XRV Start-Up, Operation And Maintenance Instructions Manual

Power Up the Controls and Check the Oil
Ensure that an oil level is visible in the compres-
Heater —
sor before energizing the controls. A circuit breaker in the
VFD energizes the oil heater and the control circuit. When first
powered, the ICVC should display the default screen within a
short period of time.
The oil heater is energized by powering the control circuit.
This should be done several hours before start-up to minimize
oil-refrigerant migration. The oil heater is controlled by the
PIC III and is powered through a contactor in the power panel.
A separate circuit breaker powers the heater and the control
circuit. This arrangement allows the heater to energize when
the main motor circuit breaker is off for service work or
extended shutdowns. The oil heater relay status (OIL HEATER
RELAY) can be viewed on the COMPRESS table on the ICVC.
Oil sump temperature can be viewed on the ICVC default
screen.
SOFTWARE VERSION — The software part number is
labeled on the backside of the ICVC module. The software
version also appears on the ICVC configuration screen as the
last two digits of the software part number.

Software Configuration

Do not operate the chiller before the control configurations
have been checked and a Control Test has been
satisfactorily completed. Protection by safety controls
cannot be assumed until all control configurations have
been confirmed.
As the 19XRV unit is configured, all configuration settings
should be written down. A log, such as the one shown on pages
CL-1 to CL-12, provides a list for configuration values.
Input the Design Set Points —
point screen and view/modify the BASE DEMAND LIMIT set
point, and either the LCW SETPOINT or the ECW SET-
POINT. The PIC III can control a set point to either the leaving
or entering chilled water. This control method is set in the
EQUIPMENT SERVICE (TEMP_CTL) table.
Input the Local Occupied Schedule (OCCPC01S) —
Access the schedule OCCPC01S screen on the ICVC and set
up the occupied time schedule according to the customer's
requirements. If no schedule is available, the default is factory
set for 24 hours occupied, 7 days per week including holidays.
For more information about how to set up a time schedule,
see the Controls section, page 14.
The CCN Occupied Schedule (OCCPC03S) should be con-
figured if a CCN system is being installed or if a secondary
time schedule is needed.
NOTE: The default CCN Occupied Schedule OCCPC03S is
configured to be unoccupied.
Input Service Configurations —
figurations require the ICVC screen to be in the SERVICE por-
tion of the menu.

PASSWORD — When accessing the SERVICE tables, a pass-
word must be entered. All ICVC are initially set for a password
of 1-1-1-1 in the ICVC CONFIGURATION SCREEN.
INPUT TIME AND DATE — Access the TIME AND DATE
table on the SERVICE menu. Input the present time of day,
Access the ICVC set

date, and day of the week. The HOLIDAY parameter should
only be configured to YES if the present day is a holiday.
NOTE: Because a schedule is integral to the chiller control
sequence, the chiller will not start until the time and date have
been set.
NOTE: The date format is MM-DD-YY for English units and
DD-MM-YY format for SI metric units.
CHANGE ICVC CONFIGURATION IF NECESSARY —
From the SERVICE table, access the ICVC CONFIGU-
RATION screen. From there, view or modify the ICVC CCN
address, change to English or SI units, and change the
password. If there is more than one chiller at the jobsite,
change the ICVC address on each chiller so that each chiller
has its own address. Note and record the new address. Change
the screen to SI units as required, and change the password if
desired.
TO CHANGE THE PASSWORD — The password may be
changed from the ICVC CONFIGURATION screen.
1. Press the and
