This command allows the user to force a backup condition for maintenance and test
purposes. This command must be sent to the converter designated as the backup
Converter (i.e., “BU”). When activated this command forces the backup Converter to
assume the state of the specified chain converter and forces the chain converter offline.

backup controller, xx_yy_z = BU_yy where yy is the number of converters in the chain
(i.e. 01 to 12). If Redundancy ON and converter is selected as a chain unit xx is the
converter number (01 to 12), yy = P1 or P2 for single or dual polarity system, and z = A if
Auto Mode or M if Manual Mode.
