5.5 TRACK STATUS Indicator
The “TRACK STATUS” “ indicator shows that there is voltage on the track.
The color indicates the type of signal. If it is orange the track is getting DCC
signals with no analog zero stretching. If the color is green or red then a
“stretched zero” signal is being used to operate a conventional locomotive.
When zero stretching is present, the DCC decoder equipped locomotives will
read their digital commands normally and perform as commanded. If the Track
Status Indicator is not lit there is no voltage on the track, the track power to the
DB150 may be OFF.
5.6 OFF LINE Indicator
The DB150 automatically shuts down when the heat sink temperature rises to
around 45 to 50 degrees Celsius and the “OFF LINE” indicator will glow red.
The DB150 automatically resumes operation when the heat sink cools down to
approximately 40 degrees Celsius.
The “OFF LINE” indicator will also be lit when there is no track status. This is
normal and you should not be alarmed.
5.6.1 Troubleshooting DB150 Shutdowns
If the DB150 unit shuts down occasionally due to a track short circuit:
1. Correct the short circuit condition and the booster will resume normal
operation.
2. Turning off the booster when a short occurs is not necessary since it
will re-start automatically when the short is cleared.
If the DB150 unit shuts down frequently:
1. Move the DB150 so that the heat sink has a flow of cool air.
2. Place the DB150 out of direct radiant heat like sunshine or a room
heater.
3. Try direct cooling by using a small fan to blow air onto the heat sink.
4. Lower the track load current.
5. Reduce the input voltage from the transformer.
If the DB150 beeps 5 times and shuts down briefly and then comes back on
again
, it is probably being run too close to its pre-set current limit. In this case
it may clip or mutilate some outgoing packets to keep the track current within
acceptable limits. To solve this problem, reduce the track current load by set-
ting up additional power districts to provide more total power for the layout.
5.7 CONFIG A & B
The “CONFIG A” and “CONFIG B” terminals allow the DB150 to be set up
as a command station, a booster or an auto reversing booster.
