5.4.7. Alarm parameters
Menu level
Threshold values / limit values,
LI-1:
Default:
2000
The limit value defines the threshold, that activates/deactivates an alarm.
Dependency alarm 1,
ALrM.1:
Default:
actua
The dependency of alarm 1 can be related to special functions, in detail these are the current
measuring value, the min-value, the max-value or the totaliser/sum-value. If
Hold
was selected,
then the alarm is hold and processed just after deactivation of
HOLD
.
EHtEr
causes the
dependency either by pressing the
[O]
-key on the front of the housing or by an external signal
via the digital input. With
[P]
the selection is confirmed and the device changes into menu level.
Hysteresis for threshold values,
HY-1:
Default:
00000
The delayed reaction of the alarm is the difference to the threshold value, which is defined by
the hysteresis.
Function for threshold value undercut / exceedance,
Fu-1:
Default:
high
A limit value undercut is selected with
Louu
(for LOW = lower limit value), a limit value
exceedance with
High
(for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function
High
, an alarm is activated by reaching of the threshold level.
If the threshold value was allocated to
Low,
an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
