Configuration
With the beeper you can choose between a continuous or an intermittent tone. With
Flashing Display the 7-segment display flashes. By pressing a front panel button the
beeper and the flashing display will be reset.
Console push-messages
:
This option allows the output of sensor values on the con-
sole at a configured time interval, or when a certain threshold has been reached.
Min/Max measurement period: Selects the time range for the sensor min/max values
on the overview web page.
Enable beeper for AC alarms: Activates the beeper for all AC limit messages.
Enable beeper for sensor alarms: Activates the beeper for all sensor limit messages.
System Events
If you select "System" as Sensor, it is possible to select the message channels for
global events, such as switching a port.
Hysteresis Example:
A Hysteresis value prevents that too much messages are generated, when a sensor
value is jittering around a sensor limit. The following example shows the behavior for a
temperature sensor and a hysteresis value of "1". An upper limit of "50 °C" is set.
Example:
49.9 °C - is below the upper limit
50.0 °C - a message is generated for reaching the upper limit
50.1 °C - is above the upper limit
...
49.1 °C - is below the upper limit, but in the hysteresis range
49.0 °C - is below the upper limit, but in the hysteresis range
48.9 °C - a message is generated for underrunning the upper limit inclusive hysteresis
range

Port Switching
Depending on the measured Current and the measured sensor values, switching ac-
tions can be triggered. During operation, the actions configured for crossing the limits
are executed. For example, when a value moves from the range "above max value" in-
side the range "below max value", the action defined for "below max value" is per-
formed. In the case of device start, configuration or plug-in of the sensor, the actions
corresponding to the range in which the current temperature is located are switched.
Example with "Maximum value" of 65 °C, "Minimum value" of 25 °C and hysteresis of 3
°C. The dotted line shows the hysteresis.
