4.4.2 AUTOMATIC CONFIGURATION VERIFICATION
The backup converter has a menu that allows the operator to choose, on a converter-by-
converter basis, manual (M) or automatic (A) operating mode.
Figure 30 shows the system configured for automatic (A) operation. In this mode,
failure of an online converter will automatically cause a switchover to the redundant unit
to occur. In the field, the simplest way to test this mode is to turn off an online unit. The
AUTO/MANUAL selection is made in the converter. The online units will report their
status as show in Figure 30.
