Hysteresis
2
0.00 to 21000000.00
[1.00]
During monitoring, the actual
value must exceed or fall below
one of the limits defined in
parameter
recognized as out of permissible
limits. For a value to register as
having returned to the permissible
limits, the monitored value must
rise above or fall below this value
for the hysteresis.
The format for entering the
hysteresis depends on the
monitored analog input and
corresponds with the one of the
threshold listed in parameter
.
4207
Delay
2
0.02 to 99999.99 s
[1.00 s]
If the monitored value exceeds or
falls below the threshold value for
the delay time configured here, an
alarm will be issued. If the
monitored value falls below the
threshold (plus/minus the
hysteresis, dependent on
parameter
) before the
delay expires the time will be
reset.
Beginning: For flexible limit 25 ... 32 only; sample refers to flexible limit #25.
6646
Fallback time
2
00.02 to 99999.99 s
[1.00 s]
If the monitored value exceeds or
falls below the threshold value, a
counter will start and finally
disable the alarm. If the monitored
value comes back into the
threshold value (plus/minus the
hysteresis) before the fallback
time expires the time will be reset.
End: For flexible limit 25 ... 32 only; sample referred to flexible limit #25.

Alarm class
2
Class A, Class B, Class C, Class D,
Class E, Class F , Control
[Class B]
Each limit may be assigned an
independent alarm class that
specifies what action should be
taken when the limit is surpassed.

Self acknowledge
2
Yes
The control unit automatically
clears the alarm if the fault
condition is no longer detected.
[No]
The control unit does not
automatically reset the alarm
when the fault condition is no
longer detected.
The alarm must be acknowledged
and reset by manually pressing
