6.6.3.1 Overview of Output Relay Channels and Configuration
One active control can be mapped for each of the relays; for example, Relay 1 can be unassigned from
LVD 1 then remapped as an alarm relay.
Any alarm (even multiple alarms) can be mapped to any unoccupied relay.
Figure 3 summarizes the output channel assignments:

6.6.4 Examples of Alarm Categories
6.6.4.1 Rectifier Alarms
Rectifier Fail
Sets an alarm condition for a true or actual rectifier failure. The activation
value is factory set.
Rectifier Minor
Sets 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
Sets the total number of rectifier fail alarms that trigger the rectifier major
alarm. The activation value must be greater than or equal to the number
entered for the minor rectifier fail count alarm.
Rect. Minor Fail Count
Sets the total number of rectifier fail alarms that trigger the 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)
Sets an alarm condition when a Pathfinder series rectifier lockout is detected.
The activation value is factory set.
Out of Tolerance
Sets an alarm condition when a rectifier out of tolerance is detected. The
activation value is factory set.
Rect. Comms Lost
Sets an alarm condition when rectifier communications is lost. The activation
value is factory set.
Rect. Equalize Activated
Sets an alarm condition when a rectifier in EQ mode is detected. The
activation value is factory set.
Rect. AC Mains Fail
Sets 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
Sets an alarm condition when the maximum number of rectifiers is
exceeded. The activation value is factory set.
