Miscellaneous Faults - Nuvation Energy NUV300-BC-12 Product Manual

▪
Typically disabled
pi_fault_factory_verify_wdt
▪
Fault indicating the factory registers on the power interface subsystem have not been
periodically being validated against non-volatile memory.
▪
Typically disabled
10.1.9.1. Initialization Issues
The stack_fault_cell_wdt, stack_fault_therm_wdt, stack_fault_ci_wdt, and stack_fault_open_wire_wdt can
be uninitialized due to problems with the Link Bus. Refer to
sc_fault_ram_test_wdt,
The
pi_fault_factory_verify_wdt,
initialize as they are core to the battery management system and does not have associated
configurability.
Please contact Nuvation Energy at
The sc_fault_pi_afe_wdt and stack_fault_power_wdt can be uninitialized due to disabling the power
interface subsystem's AFE or a high amount of noise on the DC bus.
The sc_fault_controller_wdt can be uninitialized if there is no external controller updating the
heartbeat. In this case this fault should be disabled.

10.1.10. Miscellaneous Faults

sc_fault_config
▪
Fault indicating that there was an error reading the non-volatile storage of the battery
management system configuration. A default configuration is used when this fault occurs and
the battery management system will fail to exit Service Lockout. Once a configuration has been
successfully imported into the battery management system and saved, this fault should not
occur. Note that during an upgrade of the battery management system, the configuration is
deleted to avoid incompatibility with the upgraded version.
sc_fault_config_factory
▪
Fault indicating that there was an error reading the non-volatile storage of the battery
management system factory configuration. This is similar to sc_fault_config; refer to that fault
for more details.
sc_fault_config_factory_verify
▪
Fault indicating that verification of factory configuration settings against non-volatile storage
has failed on the stack controller subsystem This typically means either a setting was changed
after saving or non-volatile memory has been corrupted.
pi_fault_config_factory_verify
▪
Fault indicating that verification of factory configuration settings against non-volatile storage
has failed on the power interface subsystem This typically means either a factory setting was
