1-44 Maintenance overview
If a REx test fails, the system generates a PM600 log. The PM600 log
initiates a major alarm for the XPM that failed the REx test. The major
alarm appears at the MAP terminal under the PM banner at the top of the
display.
If an in-service (InSv) or out-of-service (OOS) diagnostic test fails, the REx
failure reason includes the mnemonic. The mnemonic is an
easy-to-remember abbreviation. The mnemonic is for the failed diagnostic
and the failed unit (0 or 1).
Log PM600 details the following:
The log includes REx steps that occurred after the failed step. These steps
are recovery actions the REx test initiates because of the failure. The log
includes the number if the REx action is unit specific. Unit specific actions
include BSY unit, RTS unit, TST unit, and synchronization. The log does
not include the REx action that affects the node, like SWACT, and BSY both
units. The additional data of the logs contains a cardlist and mnemonic of
the failed diagnostic. The diagnostics and a description of the diagnostic
appear in the following table.
