Littfinski Daten Technik DigitalBooster DB-2 Operating Instructions

To enable the DigitalBooster DB-2 to supply the maximal possible digital current it
has to get a minimum of 52VA from a model railway transformer at clamp KL1.
The transformer output voltage can be between 16 and 18 Volt AC.
If the transformer supplies already other consumers on the layout you have to take
special attention to the correct terminal occupation at the supply clamp KL1. You
have to attend to the correct colors "yellow" and "brown" by connecting to a
command station of Märklin Control Unit or Intellibox.
3. Booster connected to a rail:
The digital current of the DigitalBoosters DB-2 is available at clamp KL2 next to the
light emitting diode.
Each booster must supply an own current circuit on the layout.
Therefore the center conductor of a 3-conductor rail has to be isolated at the
joint to the next current-circuit.
The output "brown" of the clamp KL2 supplies both rails. The output "red" supplies
the center conductor of the isolated section.
On the 2-conductor rail shall as minimum one rail be isolated at the joints. The
rail inside the isolated section gets the supply from the output "red" of the booster
clamp KL2. The second rail (not necessarily isolated) receives the supply from
output "brown".
Booster in action:
After switching-on the model railway layout and actuating the push button "GO" at
the command station the red light emitting diode (LED) of the DigitalBooster DB-2
will glow. This indicates that the booster supplies digital current to the connected rail-
section.
The booster will switch automatically off by any short circuit at the rail section.
The red light emitting diode will go out. The event of a short circuit will be reported
from the booster to the command station via the 5-poles booster bus. These will
switch to "Stop".
After eliminating the short circuit you can supply digital current to the rail by
actuating again the push button "Go" at the command station.
Will the current at the connected rail section extend 2.5 Ampere the booster will
switch off as well, to prevent overheating.
Booster assembly:
Please assemble the Booster DB-2 at a location that sufficient air can circulate at
the heat sink.
If you have purchased the Booster DB-2 as a kit you can assemble the completed
unit into a suitable empty case LDT-01. This case is available as accessory within
our program.

Operating Instruction
DigitalBooster DB-2
from the Digital-Professional-Series !
DB-2-G
>> finished module in a case <<
The DigitalBooster DB-2 is a short-circuit-proofed power
amplifier (booster) for digital model railway layouts.
Maximal power output: 2.5A.
The DB-2 amplifies the data formats Märklin-Motorola, mfx®,
M4 and DCC
The DB-2 can be directly operated on several digital
command stations by use of the attached 5-poles booster-
⇒
Control Unit (6021)
⇒
Central Station 1 and 2 (CS1 and CS2)
⇒
Intellibox, EasyControl, ECoS, DiCoStation, KeyCommander
⇒
TWIN-CENTER
