This value determines how long a limit needs to be
continuously transgressed, until an alert is triggered.
In this example, a delay of two minutes is configured. The
limit value is exceeded at 1:30
(1)
. However, the device only
triggers an alert once the value is exceeded for the entirety
of the configured delay, in this case two minutes
(2)
.
Please be aware that the dead-band also applies to the
delay. This means that the value needs to return towards its
normal state by the dead-band value during the delay time,
in order to cancel the alert. In this example the sensor would
therefore need to measure a value below 25 °C within two
minutes of the first transgression, in order to cancel the
alert.
5.1.3 Variation Alerts
Querx can notify you if values rise or sink more quickly than
usual. In order to set this type of alert up, you will need to
enter a value for the maximal accepted fluctuation between
the highest and lowest values. Additionally, a value for the
timespan, within which the specified fluctuation value is not
to be exceeded, is required.
These alerts remain active until the values are once again
stable.
Individual values can be entered for falling and rising
temperatures.
