2.8 Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below
in
Figure 2.8
. By inserting the wires, it will detect the fault status including power failure or port link
failure (managed industrial switch only) and forma normally open circuit. An application example
for the fault alarm contact is shown below in
Figure 2.8
.
Note
The wire gauge for the terminal block should range between
12 ~ 24AWG
.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to
eliminate power fault alarm.
