Software Configuration

WARNING
Do not operate the chiller before the control configurations
have been checked and a Control Test has been satisfacto-
rily completed. Protection by safety controls cannot be
assumed until all control configurations have been con-
firmed. Do not assume the values in the chiller are correct.
They should match the chiller labels and data sheets for the
selection. If you have questions contact the Carrier Techni-
cal Service Manager or Service Engineering.
Consult the 23XRV with PIC6 Controls Operation and Trouble-
shooting manual for controls-related issues. As the unit is config-
ured, the configurations should be written down or a file should be
generated using ProView service tool to have settings for any fu-
ture needs. When installing new software, be sure to select to keep
all configuration data so that all data does not have to be reentered
manually. If new parameters are added to the new software they
will need to be manually configured. As the 23XRV unit is config-
ured, all configuration settings should be written down. A log,
such as the one shown on pages CL-1 to CL-10, provides a conve-
nient list for configuration values.
It is recommended that all control configuration tables be upload-
ed via Service Tool and stored for reference when the software
configuration is complete.
