Appendix B. Faults/Events

There are three types of Faults/Events that may occur and be recorded in the event log of an

MBT-4000B or BUC-4000. These are:

• Summary Faults

• Configurable Summary Faults

• Informational Events

Summary Faults indicate improper operation. When a Summary Fault condition occurs: The

Summary Fault Relay will be de-energized. If a Summary Fault occurs on a converter, it will

mute. If a Summary Fault occurs on the base unit, the applicable converters (one or both) will be

muted according to the specific error. If a Summary Fault occurs on the on-line unit of a

redundant pair, the off-line unit will detect the fault and assume on-line state. In all cases, a

corresponding event message will be added to the event log.

Configurable Summary Faults operate the same as Summary Faults, except Configurable

Summary Faults may be enabled/disabled via remote commands.

Informational Events are operation conditions, which may be important, but are not considered

improper operation and will not cause a converter to mute.

Tables B1through B5 list possible Fault/Event messages.
