Example of an alarm loop
The following example shows an electrical circuit with DC power source connected to
the switching input of the loggers. If an alarm is raised by the alarm device (e.g. light
barrier) is activated, the circuit is closed and the switching input is triggered.
Depending on the alarm configuration, one or two of the internal relays are switched
in order to activate / trigger the load connected to the respective switching output (in
this case a signal lamp) and a SMS and / or email can be sent to predefined
receivers.
Alarms can also be triggered when the value of a monitored measurment crosses a
predefined threshold. Please refer to section 5.2 for detailed information on how to
configure the threshold monitoring.
