digital track voltage supplied.

7.10 OFF LINe Indicator
The DCS100 automatically shuts down when the heat sink temperature rises to
around 113-122 degrees Fahrenheit (45 to 50 degrees Celsius) and the
OFF
LINE
indicator will glow red. The DCS100 automatically resumes operation
when the heat sink cools down to approximately 104 degrees Fahrenheit (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.
7.10.1 Heat Dissipation
It is normal for the DCS100 to be warm to the touch when it is in use. It is
designed to absorb and dissipate the power difference between the input volt-
age and the selected scale output stabilized voltage, at the current load being
drawn. If the unit is not able to dissipate excess heat, over temperature thermal
shutdown may occur. We recommend that you locate the boosters in a location
where they can dissipate heat. If you experience frequent over temperature
shutdowns, add a small fan to help cool the booster.
7.10.2 Troubleshooting DCS100 Shutdowns
1. Move the DCS100 so that the heat sink has a flow of cool air.
2. Place the DCS100 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 power supply.
If the DCS100 beeps 4 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.
