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.
