Alarm relay (X2)
The EDS500 devices are equipped with a potential free
alarm output (relay with isolated switchover contact).
This output corresponds to a device alarm and is
activated when the device looses the power supply
or the alarm LED is constantly on. The reason for the
signaling of an alarm can be referenced in the system
alarm table (EDS500 Manual - Part 2: Alarms and alarm
configuration).
