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 !
Automatic switching on after a short circuit
After a short circuit the B-4 switches on automatically after 4 to 10
seconds (adjustable). If the short circuit is still there, it switches off
again immediately.
In state of delivery, the automatic switching on will be interrupted for
one minute after the booster has been switched on and off five times.
This autostarting time can be set individually:

to the set autostarting time after a short circuit (4 to 10 seconds) or

to an individual autostarting time between 0 and 90 seconds
(adjustable in 10 sec.-steps).
