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, the totaliser value/sum-value, the constant
value or the difference between the current measurand and the constant 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.
Example:
By using the maximum value
Alarm.1
=
Max.va
in combination with a threshold monitoring
Fu-1 = High
, an alarm confirmation can be realised. Use the navigation keys, the 4th key or the
digital input for confirmation.
Threshold values / limit values,
LI-1:
Default:
2000
The limit value defines the threshold, that activates/deactivates an alarm.
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.
