A relay cannot be assigned to more than one alarm. If a relay is already included in an
existing channel configuration, it cannot be used in combination with any other channel
or switching input.
Perform the following steps to configure the alarm thresholds:
Step Description
1
In the segment
Alarm Trigger – Settings
specify whether there is a minimum
and / or a maximum threshold to be monitored by activating the respective
checkbox(es).
2 Enter the minimum and / or the maximum threshold into the respective field(s).
Input of negative values is possible.
(Example of temperature sensor: min. level: -15°C)
For flow sensors, the sign indicates the flow direction of the fluid.
(Example: 5 l/s corresponds to 5 l/s forward flow;
-5 l/s corresponds to 5 l/s reverse flow)
3 A hysteresis and a debounce value can be defined for alarm input preventing a
constant triggering of the alarm by measuring values fluctuating marginally
around the threshold.
Enter a Hysteresis value. The Hysteresis value in percent designates a
symmetrical range around the specified threshold the input signal can fluctuate in
without having an impact on the current alarm status.
Example: (pressure sensor)
Min. level: 2.0 bar
Hysteresis: 10 %
The alarm does not switch on until the input signal reaches 90 %
of the specified threshold (here 1.8 bar). After this, the alarm does not
switch off until the input signal exceeds 110 % of the threshold
(here 2.2 bar).
