- 10 -
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.
