5.4.2 Monitor Menu Options
The Monitor window has a menu bar at the top with a drop-down list of options for each menu.
Table 7 summarizes the options available in these menus.
5.4.3 Panel 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.

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.
