6.1.4
Alarm
Number
Description
Explanation / Function
1
Next Action
Shows the date and time when the measurement task takes place and the alarm condition will
be checked
2
Interval
Enter the time interval of the measuring and checking of the alarm condition
3
Alarm-Channel
Defines the channel which must be monitored
4
Alarm-Type
ON/OFF hysteresis, value change(delta/time)
5
Send Alarm X times
Determines how often a message is sent, when the alarm condition is true (only with ON/OFF
alarm type)
6
Alarm ON value
Defines the alarm ON threshold
7
Alarm OFF value
Defines the alarm OFF threshold
8
Alarm value (change per interval)
The minimum value by which a parameter must have changed since the last alarm
measurement to trigger the alarm. The parameter must be specified as a positive value. This
value then applies both, to positive and negative changes by this amount.
6.1.4.1
Alarm type
The alarm condition is check and activated as soon as the set date and time is reached. After that the condition will be
checked in the desired interval.
6.1.4.1.1
ON / OFF
If Alarm ON value ≥ Alarm OFF
value, then the alarm will be sent
above
a certain level
Alarm message is triggered if the measured value of the selected channel is greater
than the Alarm ON value. During this period the alarm will be send X times (Number
5), if the measured value is still greater than the Alarm OFF value (Hysteresis = Alarm
ON
–
Alarm OFF value).
If Alarm ON value < Alarm OFF value, then the alarm will be sent
below
a certain level
Alarm message is triggered if the measured value of the selected channel is less than
the Alarm ON value. During this period the alarm will be send X times (Number 5), if
the measured value is still lower than the Alarm OFF value (Hysteresis = Alarm OFF
–
Alarm ON value).
NOTE: If the alarm condition is active and X alarm messages are sent no more alarm message will be sent. The alarm is
only re-armed when the Alarm OFF condition is fulfilled.
6.1.4.1.2
Delta
An alarm will be sent when the last measurement is a least that amount (Number 8) higher or lower than the actual
value.
