3.1.4Backup Converter Operation

The Backup Converter must be programmed to store all of the Converter Frequencies and Gains in the system, in its Satellite Memory Locations, corresponding to the Converter Number (1 to 8) labeled on the StarSwitch Interface cables. Figure 3-7 shows the Backup Converter in Auto Mode ready to Backup any converter in the system and after backing up Converter 2.

3.1.5 StarSwitch Alarm

The StarSwitch Alarm is displayed as “Fault” in the StarSwitch Menu Window on the Backup Converter only. A fault indicates either an internal StarSwitch Unit failure or a Power Off condition detected on any one of the Converters in the system. The StarSwitch Alarm however, does not activate the Summary Alarms, and the Backup Converter will still backup an Online Converter when it is powered down. Figure 3-8 shows the Backup Converter display after Converter 1 has been powered off and the Backup has taken over.

3.1.6 Dual StarSwitch Operation

Each LT3600 Converter has two StarSwitch Interface connectors (J8, Main and J5, Secondary) to control two StarSwitch Units, for systems where switching for both Up and Down Converter sections is required. The two interfaces are not independent as an alarm in either Up or Down Converter system will cause both to switch to the backup converter. This is necessary since a failed unit, including both Up and Down Converter sections, will need to be removed for service. Ensure that J8, Main Interface, is used if only one StarSwitch Unit is configured in the system.
