The following sections describe the menu headings and the associated lists of items.

6.5.3.2

Rectifier Alarms

Rectifier Fail
This menu item enables the Supervisor to set an alarm condition for a true or actual rectifier
failure. The activation value is factory set.

Rectifier Minor
This menu item enables the Supervisor to set an alarm condition for a minor rectifier failure; i.e.,
an alarm condition detected in a rectifier, but one that is not considered an immediate threat to
the operation of that rectifier. The activation value is factory set.

Rect. Major Fail Count
This menu item enables the Supervisor to set the total number of rectifier fail alarms that will
trigger the CXC’s rectifier major alarm. The activation value must be greater than or equal to the
total number entered for the minor rectifier fail count alarm.

Rect. Minor Fail Count
This menu item enables the Supervisor to set the total number of rectifier fail alarms that will
trigger the CXC’s rectifier minor alarm. The activation value must be less than or equal to the
number entered for the major rectifier fail count alarm.

Rectifier Lockout (Pathfinder series only)
This menu item enables the Supervisor to set an alarm condition when a Pathfinder series
rectifier lockout is detected. The activation value is factory set.

Out of Tolerance
This menu item enables the Supervisor to set an alarm condition when a rectifier out of
tolerance is detected. The activation value is factory set.

Rect. Comms Lost
This menu item enables the Supervisor to set an alarm condition when rectifier communications
is lost. The activation value is factory set.

Rect. Equalize Activated
This menu item enables the Supervisor to set an alarm condition when a rectifier in EQ mode is
detected. The activation value is factory set.

Rect. AC Mains Fail
This menu item enables the Supervisor to set an alarm condition when a rectifier AC mains fail
is detected. The activation value is factory set.

The activation value for AC Mains Fail detection is determined to be when the number of
rectifiers in AC Fail divided by the number of rectifiers acquired is greater than or equal to 90%.

Max Rectifiers Exceeded
This menu item enables the Supervisor to set an alarm condition when the maximum number of
rectifiers is exceeded. The activation value is factory set.

Fan Fail Alarm (for Fan Cooled Systems)
The purpose of this feature is to enable the CXC to trigger the alarm when a fan fail (speed
error or failed fan) condition has occurred in any of the rectifiers in the system.

The Fan Fail Alarm is true when the CXC receives a Fan Fail or Fan Speed Error alarm from any
rectifier.

The Fan Fail Alarm is cleared when all Fan Fail and Fan Speed Error alarms are cleared from all
the rectifiers.

Each time that the Fan Fail Alarm goes on/off, the “event” is logged in the Event History. Since it
is a rectifier alarm, up to nine rectifiers (up to 27 fan fail alarms) that are in alarm will be logged.
If more than nine rectifiers are in alarm an additional entry will be made indicating the total
number of rectifiers in alarm.

The activation value is factory set.

Power Save
This menu item enables the Supervisor to set an alarm condition when a rectifier is in Power
Save mode. The activation value is factory set.
