different conditions to detect abnormal operation. The following Active
Converter faults are listed by name, fault code number, type, description of
the condition, and corrective action required by the user where applicable.
With the ability to connect larger frame size power structures in parallel,
each structure has independent fault detection to indicate the source of the
problem (for example, PS1 for Primary Converter and PS2 for Secondary
Converter).
