Current Limit Management of Rectifiers
The amount of total AC power that the rectifiers are using can be limited by the RMS. The rectifier total DC
current limit parameter specifies the total DC current limit for all of the rectifiers combined. If the load needs
more than the rectifiers can provide with this limit, the BBU modules will make up the difference.
Rectifier Intelligent Power Matching (Energy Optimization Mode)
The SCC Controller provides an Energy Optimization Mode function. Energy Optimization permits an
installation to only operate rectifiers as needed to maintain the load. As load increases, Energy Optimization
turns on additional rectifiers as needed to maintain the load. As load decreases, Energy Optimization places
rectifiers in standby to conserve energy usage. Rectifiers which are always operating to maintain any load
requirements are cycled through the group of rectifiers controlled by this feature to provide uniform operating
times for each rectifier.
Rectifier and BBU Module Data Monitoring
The SCC Controller monitors the components comprising the system (such as the rectifier modules) and
generates alarms if a fault condition occurs.
These are accessed via the SNMP/V2 interface. See “SCC Controller Interaction with the RMS” on page 12.
Alarm Detection and Reporting
The SCC Controller reports alarm conditions via SNMP traps over Ethernet. The SCC Controller acquires and
analyses real time data from the system’s components such as the rectifier modules. The SCC Controller uses
this data to process alarms. The SCC Controller also maintains an alarm history log.
These are accessed via the SNMP/V2 interface. See “SCC Controller Interaction with the RMS” on page 12.
Alarm Logs
The alarm logs can be viewed using the Web Interface or via SNMP and consist of...
•
Alarm History Log: Log of most recent alarms.
•
Active Alarm Log: Log of active alarms.
NOTE!
Once maximum number of log entries is reached, new entries overwrite oldest entries.
