Cause 1: The current sampled value was less than or equal to the lower threshold, and the previous sampled value was greater than the lower threshold.
Cause 2: The alarm table became valid, the first sampled value was less than or equal to the lower threshold, and fallingAlarm is equal to risingAlarm or risingOrFallingAlarm, an alarm is generated.
