Status
This area of the menu system provides an overview of system components, threshold settings,
and feature configuration. No configuration is possible from the status portion of the menu
system. Equivalent items are available through the craft port web pages.
Rectifiers
Information such as the total installed rectifier capacity in the system, total on-line rectifier
capacity in the system (those producing power), total output current of all rectifiers, and the
individual rectifier output currents by rectifier number (Gmn) are available. “m” represents
the shelf number and “n” represents the rectifier position number in that shelf.
Batteries
The following battery management information is available under Status:
Installed Capacity User entered system battery capacity in AH. Automatically entered when
using smart Lithium batteries.
Number Of Strings The total number of battery strings installed in the system.
Current Current flowing into or out of the batteries.
Highest Temp Highest battery temperature being measured by the thermal probes.
Temp Probes Number of installed thermal probes.
Mid-Cell Volts Number of installed Mid-cell voltage measurement modules.
Battery Test Result Shows whether the most recent battery test was completed, and the reserve
time.
Next Test The date of the next automatic battery discharge test. The automatic
discharge test feature must be enabled for this to work.
Shunt Currents
Up to six shunt measurements can be displayed through appropriate Distribution Control and
Monitoring modules. The NX400 is equipped with four QS871 distribution control and
monitoring modules. These modules are used to monitor one total battery current and each of
the three Load bus currents.
Disconnect States
The status of the LVBD (Low Voltage Battery Disconnect) and LVLD1-3 (Low Voltage
Load) disconnects are displayed in this menu. “None” is displayed for each contactor that is
not configured to be present in the system. In the normal NX400 system state, all contactors
should show “Closed”. A state of “Open” will be showed for contactors that have been
disconnected.
Alarm Thresholds
This section of the menu shows the present alarm threshold settings in xx.xV format. These
values are set by factory default but can be individually configured in the field. Appendix B
and C provide additional details on factory settings.
