Switch Fault/Status Connector (J11)
The RCU101 Redundancy Control Unit contains a summary Fault/Status connector that is
available to the equipment operator for the purpose of monitoring the summary fault status of
both converters as well as the individual status of the converters. The pinouts of this 15-pin D
SUB connector are as follows:

The primary and backup summary fault relay contacts provide fault indications to flow through
the switch into one common connector. In addition, the two Form-C summary fault contacts on

converter is presently online. Continuity of these contact closures implies online status for the
indicated converter.
