This holds the major-low alarm threshold configured for the Offset Control parameter, in dB. If currentValueOffsetNomCnt falls below this threshold, the module raises a majorLowAlarm condition reflected in alarmStateOffsetNomCnt, signaling a serious low-side deviation in the adjustable counterpart to the Offset Monitor reading, letting an operator nudge that internal offset back toward nominal. An admin sets this as the floor beyond which the reading is considered a significant fault rather than normal variation.
