Both alarm circuits are also related to an alarm LED on the front panel.
In case of malfunction the "System" LED will indicate any type of internal fault of
the unit. This LED is flashing green in normal conditions and is red in alarm
conditions. Also this alarm is related to an relay output.
Additional to the alarm LED's each alarm circuit is equipped with a relay with
potential free alarm contacts. These contacts can be used for external processing
of the signal or for control of further functions.
If a malfunction or failure of the power supply occurs, all 3 relays will switch to
alarm condition.
