English
Short-circuit protection
The BiDiBooster provides an intergrated short circuit breaking in shape
of an integrated current limitation. This causes the booster to switch off
automatically when a short circuit occurs at the track output and thus
prevents damages to the booster, the tracks and the vehicles. The time
elapsing till the short-circuit protection switches off the booster can be
set to a value between 1 and 250 milliseconds.
When the short circuit feedback line is connected to the booster port of
the control unit, the BiDiBooster sends a feedback to the DCC control
unit when a short circuit occurs and then the control unit switches off
the booster.
The short circuit sensitivity or the interrupting current, can be set to 2,
3, or 4 A. In order to prevent damage effectively when a short circuit
occurs, the short circuit sensitivity should not be set too high.

Please note:
!
The set short circuit sensitivity should not exceed the maximum
transformer´s current. In case the maximum interrupting current is
higher than the maximum transformer´s current, the booster cannot
detect an overcurrent and thus does not switch off the current to
protect electronic components, vehicles and the tracks from damage.
Risk of fire !
