Examples are as follows:
Set Phase A overcurrent alarm of the first group of alarm enabled.
Action value: The action value is a primary value. For example, if the alarm value is set to 5.500A, when
Phase A current value exceeds 5.500A, the alarm condition is triggered and the timer starts.
Action delay time: When the alarm condition is triggered, if Phase A current value exceeds 5.500A, an alarm
record will be generated after the setted delay time (accurate to the second), Alarm group (alarm 1), alarm type
(Phase A overcurrent), alarm time (eg: 2017-5-12 14:15:20) will be recorded. If DO is associated with this alarm,
the DO acts (see DO settings).
Recovered value: The recovered value is a primary value. For example, if the recovered value is set to
5.400A, after Phase A overcurrent alarm has occurred, when Phase A current value is lower than 5.400A, the
released alarm condition is triggered and the timer starts. .
Recovered delay time: When the triggered alarm condition is released, if Phase A current value has been
lower than 5.400A, the released alarm record will be generated after the setted delay time (accurate to second),
and the alarm group (Alarm1), alarm type (Phase A overcurrent), the released alarm time (eg 2017-5-12 14:17:20)
will be recorded. If DO is associated with this alarm, the DO returns to its initial state. It can be calculated that the
alarm duration is 2 minutes.
Note: The alarm is invalid when both the action value and the recovered value are zero.

Here, you need to check the alarm type associated with DO. For
the specific alarm type, please refer to Table 1 in 5.1.2, that is, the
DO action when the alarm is generated. If it is not checked, it is
not associated, that is, DO does not operate when the alarm is
generated.
