1 - Signal contact
The signal contacts are connected via a 2-pin terminal block with screw
locking.
The signal contact ("FAULT", for pin assignment see
the remote monitoring of the device to enable remote diagnostics. You
can specify the type of function monitoring in the Management.
You can also use the Management to set the signal contact manually and
thus control external devices.
A break in contact is used to report the following conditions via the potential-
free signal contact (relay contact, closed circuit):
The failure of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
A continuous malfunction in the device (internal supply voltage).
The defective link status of at least one port. The report of the link status
can be masked by the Management for each port. In the default state, link
status monitoring is deactivated.
The temperature threshold has been exceeded or has not been reached.
