DigitalBooster DB-4 – Manual
-
7
-
The
digital current
of the
DigitalBooster DB-4
is available at the
clamp KL1
next to
the two light emitting diodes.
The DB-4 supplies
digital current
to the
own track section
via this clamp. This
section has to be
electrical separated
from the
adjoining track sections
because
those receive their
supply
from the
digital command station with integrated
booster
or from
further booster
.
4.1. 3-Conductor Track System:
If the manufacturer of your digital command station
permits
a
common layout ground
(“brown”)
the
center conductor
of the
3-conductor track
has to be
isolated
at the
cross over joints
from one to the next booster electrical circuit. The
isolated center
conductor
gets the supply from the connection “
red
” of the
clamp KL1
of the
DigitalBooster DB-4
.

Booster separation by common layout ground with isolated center conductor
If the manufacturer of the digital command station
does not permit a common layout
ground
(“
brown
”) it is required
additionally to isolate the rails
at the
cross over
joints
.
If the manufacturer of the digital command station
stipulates mandatory
the
installation of a
rocker switch
at the
cross sections
of the
center conductor
this
switch has to be
installed
.
