Readings

Downloads a .csv file with main breaker, branch circuit breaker and subfeed readings. The file

 

 

 

 

 

may be viewed with a spreadsheet program such as Microsoft Excel.

 

Event Log

Downloads a .csv file with the event log stored on the BCB. The file may be viewed with a

 

 

 

 

 

spreadsheet program such as Microsoft Excel.

 

Configuration

Downloads a .txt file with the configuration file stored on the BCB. The file includes scaling data,

 

 

 

 

 

Panelboard A and B configurations, branch circuit values and CT ratio settings.

 

Alarms Menu

 

 

 

 

Choose one of three options—Raw, Filtered or Latched—to specify how alarms are displayed.

 

Note that alarms sent over Modbus are latched independent of changes performed in the Alarms menu.

 

Raw

 

The raw alarm state is the instantaneous state of the alarm. It is not filtered and has no

 

 

 

 

 

hysteresis. When Raw is selected, an alarm is active whenever the latest reading exceeds the

 

 

 

 

 

setpoint and is cleared as soon as the reading returns to a level within the setpoint range.

 

Filtered

 

The filtered alarm uses the hysteresis interval to suppress transient alarms. A filtered alarm is

 

 

 

 

 

cleared after the alarm condition remains cleared for longer than the hysteresis interval.

 

Latched

 

Latched alarms behave like filtered alarms that get stuck on. A latched alarm stays active until

 

 

 

 

 

the alarm is manually cleared.

 

Clear All

 

Clears all latched alarms for the selected panel. Any alarm condition that is still active is latched

 

 

 

 

 

again after the hysteresis interval passes.

5.4.3Panel Status and Real-Time Clock

The Panel Status area displays:

The name of the Liebert LDM in the Unit box.

The currently selected panel in the Panel box.

To choose a different panel, click on the panel name or the A/B button. If the selected panel has any active alarms, the panel name appears in white text with a red background.

The Real-Time Clock displays the time as stored in the Liebert LDM unit. The time will not display correctly if the time zone is incorrect in the PC. If the time displayed is incorrect and the problem is not caused by a time-zone configuration problem:

• Click the Set button to force the real-time clock to synchronize with the time set on the PC.
