Alarm Types
Alarm outputs are determined by a combination of “alarm type,” “alarm value,” and “alarm hysteresis” alarm output conditions.
This section describes the “alarm type,” “alarm value,” “upper-limit alarm” and “lower-limit alarm” parameters.

5. Set value: 5 (Upper-and lower-limit with standby sequence)
Case 1
expressed as L and H. The set values are 1, 4, and 5.
If there are any overlaps in the upper and lower limits for hysteresis, the alarm will always
be OFF.
There are alarm types 1 to 2 (initial setting level), and settings should be made
independently for each alarm.
The default is 2: upper limit.

after hysteresis, the alarm will always be OFF.
Examples of case 1 and 2: In case 3, under general conditions, the alarm is turned OFF.
