4.10.4 DB210/DB220 Safe Operation Mode
We recommended when selecting a DC power supply, that the voltage slightly
exceed the track voltage at which you plan to run your layout. However, the
DC input voltage should not exceed track voltage by more than 3V. If the
DC supply voltage exceeds track voltage by more than approximately 3V the
DB210/DB220 will enter Safe Operation Mode and proportionally lower the
maximum current limit.
In safe operation mode the DB210/DB220 will limit the current available to
power the track in order to prevent damage to the DB210/DB220. When the
DB210/DB220 is in safe operation mode the PWR indicator will wink off 2
times every 4 seconds. To avoid your DB210/DB220 entering safe operating
mode and get the full 5 or 8 amps of power, your power supply voltage should
not exceed your track voltage by more than approximately 3V.
4.11 MODE Switch
The
MODE
switch settings are:
RUN
normal operations.
OP
customize the DB210/DB220 by changing its option switch set-
tings.
SLEEP
shutdown the system and all throttles that are plugged in to the
system.
4.12 NET Indicator
The
NET
indicator is a red LED that displays information about what the
DB210/DB220 sees on LocoNet. When your layout is wired correctly and
LocoNet is operating properly, the NET indicator will be on and it will wink
off any time a good LocoNet message is detected by the DB210/DB220. The
table below explains the patterns you will see for this indicator.
NET LED Indication
Meaning
Solid Red
LocoNet OK
On, wink off
DB210/DB220 detects a valid LocoNet
message
Off
DB210/DB220 detects low voltage on
LocoNet or Sleep Mode
4.13 Auto Reversing (AUTO REV) Switch
The AUTO REV switch sets if the booster or boosters are used for auto
Reversing. See section 8.0
5.0 DB210/DB220 Audible Sounds
The DB210/DB220 uses several beeps and clicks that can be used as diagnostic
tools that help you debug a number of conditions. Some Audible sounds mean
different things depending on the DB210/DB220’s current mode.
