5. Booster in Operation:
All jumpers
of the
DB-4 are set ex-factory
. The
DigitalBooster
DB-4
can be
used
immediately
at the
supplied condition
. The
factory setting
is recommended for the
first implementation
of the unit.
For selecting
different operation modes
after the first implementation please attend to
the chapter “
Adjusting Operation Modes with Jumpers
”.
After switching-on the model railway layout at first the
red LED
of the
DigitalBooster
DB-4
will
glow
. If the
red and the green LED
will
alternate flash
the
supply voltage
has
not been set
correctly
at the range of 15 to 24 Volt
. Please
check
and correct the
voltage setting
at the
DB-4-PowerSupply
.
If the
red LED
of the
DigitalBooster DB-4
will
glow constantly
after
switching-on
the
layout the
DB-4
is in operation mode and can be switched-on with the
key “Go”
of the
digital command
station
. After
switching-on
the
green LED
of the
DB-4
will
glow
and
the unit will
supply digital current
to the connected track section.
The
DigitalBooster DB-4
will be
automatically switched-off
if a
short circuit
will occur
at the track. The
green LED switches off
and the
red LED will glow constant.
The
DB-4
will report the
short circuit
via the employed
booster bus
to the
digital command
station
. Those will switch to “
Stop
”.
After
removing
the
short circuit
you can switch-on again the digital current to the track
with
the key
“Go”
.
If the current
exceeds 2.5 Ampere
within the track section the
DigitalBooster DB-4
will
switch-off as well and is reporting this
overload
to the digital command station which will
switch to
“Stop”
.
6. Adjusting Operation Modes with Jumper:
The various
operation modes
and
functions
of the
DigitalBooster DB-4
can be
adjusted with the
jumpers J1 to J5
.
6.1. Select the Maximum Digital Current to 2.5 or 4.5 Ampere:
The
Jumper J5
has been
set ex-factory.
The
DigitalBooster DB-4 supplies
with this
setting a
maximum output current of 2.5 Ampere
to the track.
This
limitation
is
suitable
for the
gauge N
to prevent the
excessive overload
to
tracks
,
vehicle wheels
and
current transmittal
in case of a
short circuit
.
