Alarm Holding Time
When the alarm object fulfill over limit condition, still need fulfill the time requirement can be
absolutely activated. In the total delay time, if the alarm object return back to the limit value,
then will not be activated. The unit for activation delay is second, value range is 0-65535. If
set the value to 0, it means the alarm will be activated at the moment object over limit
8.2.5
Alarm
Hysteresis value
When the alarm object be activated, alarm will be cancelled after real time value return
back to hysteresis value setting range. This value in order to avoid the object real time
value
frequently fluctuation at limit value which will cause to repeat alarm output. The range
can be set according to the actual object
For example: set the single cell unit voltage alarm upper limit is 2.5V, hysteresis value is
2.3V, when collector got value >2.5V will alarm, at 2.4V, alarm not cancel, return back to
2.5V will not repeat alarm. Until the voltage <2.3V, alarm be cancelled
Hysteresis value be set according to measuring point on site environment, if setting value
is 0, it means at the moment the real time value within the limit range, and [Alarm return
time] is 0, [Revert] is yes, will cancel alarm immediately. Because of collector’s repoll time
interval is long, so suggest to set this value in actual application is 0
8.2.6
Alarm Recovery Time
When alarm object fulfill over limit condition and return back to not fulfill over limit condition,
the alarm not be cancelled immediately, but to wait the alarm recovery value continue to
[Alarm holding time], then cancel alarm. if setting value is 0, it means at the moment the
object not fulfill over limit condition, and [Hysteresis value] is 0, [Revert] is yes, will cancel
alarm immediately. Because of collector’s repoll time interval is long, so suggest to set this
value in actual application is 0
8.2.7
Alarm Trigger Activation
When the alarm object generates an alarm, you can set the corresponding linkage
