TX Enable: The signal that enables the transmit signal from the Field
Interface Card to the MultiLoop Processor is active.
DS3
30V Fuse Blown: One of three fuses has blown:
F3 = digital section power regulator;
F4 = analog panel station power;
F5 = analog section power.
This LED does not indicate the status of the two fuses on the output.

Card Fault: A card fault is detected, or communications with the
MultiLoop processor have ceased.
If a c ommunication problem occurs, the output current is held at its last
value or goes to zero.
