4.6.1.3 Status LEDs
On the System Interface board, there are 22 status LEDs. The table below describes what
each lit LED means.
LED Meaning When Lit
1 Lights when wide-load-2 input is active.
2 Lights when dragging-equipment input is active.
3 Lights when input3 is active. Dark when rebroadcast.
4 Lights when AC power to the system is off and the system is running on
battery backup . This LED is unlit when AC power is present.
5 Lights when processor-A is operating properly. Slowly fading off and
on indicates normal operation.
6 Lights when output1 is active. Not used .
7 Lights when transducer TO1 is active. Will flicker as each wheel
passes over transducer TO1 during train passage.
8 Lights when transducer TO2 is active. Will flicker as each wheel
passes over transducer TO2 during train passage.
9 Lights when either advance transducer is active. Will flicker as each
wheel passes over either advance transducer during train passage.
10 Lights when transducer4 input is active. Not used .
11 Lights when transducer5 input is active. Not used .
12 Lights when voltage present at the +24 VDC input TB1 (terminal 2).
13 Lights when there is voltage from the +5-volt regulator U57. This
regulator powers the 5-volt logic and processor circuitry.
14 Lights when there is voltage from the +5-volt regulator U59. This
regulator powers the 2200-750 Reader. Plugged into P5.
15 Lights when voltage present at the +12 VDC input TB1 (terminal 1).
16 Lights continuously when the track circuit indicates a train is present at
the site.
17 Lights when wide-load-1 input is active.
18 Lights when the high-load input is active.
19 Lights when AC surge protector should be replaced. Dark when AC
surge arrestor is in working condition.
20 Lights when processor-B is operating properly. Slowly fading off and
on indicates normal operation.
21 Lights when output2 is active. Not used .
22 Lights when there is voltage from the +5-volt regulator U60. This
regulator is
currently not used .
