Figure 14: Alarm delay time
Alarm reset time (Subindex 2)
The alarm reset time defines the duration after which the alarm bits are automatically
reset again when a machine returns to a normal condition range. The alarm is reset if
the indication value was permanently below the limit value for at least the alarm reset
time, in figure 15 the reset time of 2,000ms is selected as an example.
Minimum duration of an alarm
The alarm reset time thus also implicitly defines the minimum time for which alarms
are set. If an automatic reset of the alarms is not desired, the function can be deacti‐
vated by a -1 in this subindex. This will keep all alarms until they are reset.
NOTE
In order not to lose occurred alarms, the alarm reset time should be set to -1. The
alarms must then always be actively reset via Standard Command 229.
