8. Checklist for troubleshooting and error correction
The RGB LEDs under the top of the enclosure indicate the operating status and the occurrence
of a short circuit or overheating. → Section 8.1.1 "Display and RGB LEDs".
Warning: I f you notice a strong heat development or if the booster has switched off
the track voltage due to overtemperature, disconnect the B-6 from the supply voltage
immediately.
Fire hazard! If the overheating is not caused by external influences
(obstruction of air exchange, sunlight), send the B-6 in for inspection.
8.1. Automatic shutdown
The voltage at the booster's track output is switched off, the RGB LEDs flash red-purple or
flicker yellow-orange.

Cause: The booster has switched off the voltage at the track output due to a short circuit or
overtemperature. → Section 8.1.1. "Display and RGB LEDs".
After a turnout command, the voltage at the track output of the booster is switched off.

Possible cause: The turnout address in question has been assigned to the function "Switch
off with DCC turnout command". à Avoid using the turnout address in question or assign
another turnout address to the function.
8.2. No short circuit switch-off
The control unit does not switch off in case of a short circuit although the short circuit
feedback of the booster is connected.

Possible cause when using the DCC-compliant interface: The connections C, D and E are
connected to the interface the wrong way round. Check the connections and change

them if necessary.

Possible cause when using the BiDiB connection: The digital control unit is not able to
evaluate the short-circuit feedback via BiDiB or is not configured accordingly. Check

with the instructions for the central unit whether it is possible to evaluate the BiDiB
message of the booster and if so, the configuration of the central unit.
8.3. Problems with control via the BiDi bus
The booster cannot be switched on or it transmits faulty signals (locomotives do not react as
desired).

Possible cause: The booster is installed at the end of a BiDi bus line, there is no terminating
resistor. Change the position of the booster in the bus line and install a terminating

resistor at the then last BiDiB device in the line. If this is not possible, contact our hotline
about the design of the terminating resistor for the B-6.
