Diagnostic Lamps
There are a blue and a red LED on the circuit board that may help you identify and resolve
problems.
Pilot Light
The blue pilot light indicates that the decoder is receiving power. If this light is not illuminated, it
may indicate an improperly wired decoder. It could also indicate a loose wire, poor track
pickups, no output from the command station, or another wiring problem on your layout.
Fault Light
When the decoder encounters a fault, the red fault light and all installed lighting will flash an
allotted number of times to report an error code. The number of times the light flashes
corresponds to a specific error.
Note: The fault light is connected in series with the decoder’s FX6 output (F27 by default) and
will illuminate in a steady “on” state when that function is on. This is not an error code but can
be used to check for proper operation of the fault light on a decoder.
