1 - Signal contact
The signal contacts are connected via a 2-pin terminal block with screw
locking.
The signal contact (“FAULT”, for pin assignment of terminal block, see
figure 14) monitors the functioning of the device, thus enabling remote
diagnostics. You can specify the type of function monitoring in the
Management.
You can also use the Management to switch 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 detected inoperability of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
A continuous detected error in the device (internal supply voltage).
The detected error of the 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 of the device is outside the range specified in the
threshold values.
The removal of the ACA.
The following condition is also reported in RM mode:
Ring redundancy guaranteed. By default, there is no ring redundancy
monitoring
