Note: The DB210/DB220 can only OUTPUT approximately as much voltage
as it is receiving. If you are only using a 15V DC power supply the DB210/
DB220 cannot output more than ~15V DC. Use a power supply that approxi-
mates your planned track voltage.
The DB210 is for use with DC POWER input ONLY, MAX INPUT
8 AMPS, 24VDC, DO NOT Exceed 25VDC Input.
The DB220 is for use with DC POWER input ONLY, MAX INPUT
16 AMPS, 24VDC, DO NOT Exceed 25VDC Input.
To Adjust Voltage Trim:
1. Set Mode Switch to OP. PWR indicator will flash GREEN alternating
with the PROG indicator flashing RED. DB210/220 must be connected an
active command station.
2. Select Address 01 on a throttle plugged in directly to the DB210/DB220.
Make sure any Locos with address 01 are removed from the layout.
3. Set OPSW 05 to C.
See section 7.0 for instructions on setting OPSW.
The
unit will start beeping continuously.
4. Set Scale Switch to the Scale voltage you wish to adjust.
5. Using the Throttle with 01 selected, adjust Forward Speed to increase
Voltage trim up above default. Adjust Reverse Speed to decrease voltage
trim down below default.
6. The voltage can only be adjusted up or down by the range referenced in
the chart above. The DB210/DB220 will beep continuously as long as it is
in range. When you reach a value that is out of range the DB210/DB220
will stop beeping. Once you decrease the trim UP or Down the DSC240
will beep again once you are in range.
7. To determine the actual track voltage, measure the DC voltage (unloaded)
from Rail A to Ground and Rail B to Ground, then add the two values
together.
8. Once you have set your desired voltage set the Mode Switch to RUN and
the voltage settings will be retained.
9. To set additional Scale setting voltage trim repeat steps 1-8 for each Scale
setting..
