Fault indications
Wire the relay contacts to any warning light or audible alarm in the control room as shown in
Figure 14. When a fault occurs, the relay contacts open, stopping the flow of current through
the contact circuit. This will disable the external alarm or turn OFF a light, indicating a fault.
An alarm will occur under the following conditions:
Power failure to either of the Media Converter power inputs:
o Power wires are disconnected, power source malfunction
o Input power is out of this range: 12 – 48VDC
