7.2. Factory Lockdown

Factory Lockdown is a mechanism for users to lock registers with Factory storage type as read-only.
This is typically used to protect safety related configurations for safety certification purposes.

7.2.1. Configuring Factory Registers

Factory registers can be configured in the same way normal configuration registers can be set. They
can be set through the Operator Interface Registers menu option
uploading a configuration file. Factory registers can only be configured when the system is not in
Factory Lockdown.

7.2.2. Enabling Factory Lockdown

Factory Lockdown can be enabled by writing to specific registers from the Operator Interface. The
user must follow the process below for the Nuvation Energy BMS to be considered factory-locked.
1. Ensure all factory registers are configured to their desired value
2. Write 1 to sc_factory_lockdown.requested_state
3. Write 1 to sc_factory_persist.save
4. Wait until sc_factory_persist.save is equal to 0
5. Verify sc_factory_lockdown.actual_state is equal to 1
6. Write 1 to pi_factory_lockdown.requested_state
