Home screens for other Conext SW units and other Xanbus-enabled devices in
the system.

Conext SW
Status Displayed When...
Invert The Conext SW is supplying power to loads by inverting power
from the batteries. AC input from the AC generator or grid is
absent or out of nominal range.
Qualifying
AC
The Conext SW is determining if AC input from the AC
generator or grid is within a usable voltage and frequency
range. It is also displayed when the Conext SW is awaiting
application of AC power or a command to enable invert mode.
GenSupport There is AC input from the generator, and the Conext SW is
supporting the generator by supplying additional power to the
critical loads.
The Conext SW supports the generator when the AC load
current drawn exceeds the GenSup Amps setting for 1 to 2
seconds.
The Conext SW uses stored DC capacity to load share with the
generator until the total AC load current (generator plus
inverter output) drops by 2 amps plus 10 per cent of the
GenSup Amps setting for 6 seconds.
For example, if GenSup Amps is set to 10 amps, the inverter
starts to support when the load exceeds 10 amps for 2
seconds and stops when it drops more than 3 amps below the
GenSup Amps setting, or 7 amps (2 amps plus 10 per cent of
10 amps = 3 amps).
The system can enter this state if the battery voltage is above
the Low Batt Cut Out setting and Gen Support is enabled. See
“Gen Support Settings” on page 4–22.
Bulk The Conext SW is bulk-charging the batteries from qualified
AC input from an AC generator or grid. AC input is also passed
through to the load while bulk-charging.
Absorption The Conext SW is absorption-charging the batteries from
qualified AC input from an AC generator or grid. AC input is
also passed through to the load while absorption-charging.
ABS Finish The Conext SW has completed the absorption stage and is
waiting for other Conext SWs in the system to complete
absorption. This status can occur only when there is another
Conext SW also charging the battery.
Equalize Equalization has been turned on, and the Conext SW is
equalizing the batteries after completing a full charge cycle.
