3.1 StarSwitch Operation

The LT3600 UP/DOWN Converter may be used in conjunction with the StarSwitch to provide redundancy switch over operations if configured as StarSwitch Ready. The following modes of operation may be selected.

3.1.1 Auto Mode

Upon reaching the StarSwitch Menu the information shown in Figure 3-4 will be displayed. The Information Window can have three selections, AUTO, STBY, or ON. The converter’s default is AUTO. Any of the three selections stated previously can be made, and will be activated when the ENTER key is pressed.

If a particular converter is in the AUTO mode, and an alarm is activated, it will be backed up by the backup converter if there are no other alarms in the system. REMEMBER: ONE AND ONLY ONE ALARM IN THE SYSTEM CAUSES A SWITCHOVER.

3.1.2 StandBy Mode

When STBY has been selected, the display will change to the display shown in Figure 3-5a. In this mode the converter with this selection will be backed up if there are no other alarms in the system. Upon switchover to the backup converter, the display will change to Figure 3-5b indicating STBY in the Activity Window. Under normal operation the Summary Alarm would only be ON if there were another alarm activated on the converter, however in this case, the Summary Alarm is forced to be ON regardless of the state of the other alarms. The operator can still view the state of alarms via the other menus, i.e. if an alarm has been activated it will be displayed, however the Summary Alarm will always be ON.

3.1.3ON Mode

When ON Mode has been selected, the display will change to the display shown in Figure 3-6. This mode is the opposite to the STBY mode, in that the Summary Alarm is turned OFF, so even if there was a valid alarm, the converter would not show a Summary Alarm. As in the STBY mode the operator can still view the state of the alarms via the other menus, i.e. if an alarm has been activated it will be displayed, however the Summary Alarm will be OFF.

NOTE: If the converter is already in STBY mode, a change to the ON mode will not occur, unless there is no alarm in the system.
