This read-write object sets the LNB's lower alarm current limit, valid between 10 and 400 mA. This threshold defines the minimum current draw considered normal for the connected LNB, so a current reading dropping below this limit signals the LNB may have failed open, lost its power feed, or become disconnected -- setting the limit appropriately for the specific LNB's rated draw avoids both missed failures and false alarms. For an LNB rated to draw around 120 mA under normal operation, an admin might set this lower limit to roughly 80-100 mA so a genuine LNB failure triggers an alarm while normal operating variation does not.
