BiDiBooster
Automatic switching on after a short circuit
After a short circuit the BiDiBooster 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).
Switching off at overtemperature
When overheating the booster switches off automatically for safety
reasons. Possible causes:

Hindrance to the flow of air through the ventilation slits.

Significantly higher rated voltage of the transformer than the set
track voltage in combination with a high current consumption.
Watchdog function
With this function the control unit (usually controlled by a PC software)
sends in intervalls of 5 seconds a DCC points switching command to an
address assigned to the BiDiBooster. As soon as the booster does not
receive these commands any longer, it switches off automatically.
After switching on the booster the watchdog function is initially inactive.
It will be activated by sending a switching command to the assigned
points address. This allows you to run the layout without a PC control
and without deactivating the watchdog function.
As soon as the BiDiBooster is connected to an interface via the BiDiB-
port, the watchdog function is inactive.
