Einar erklärt Eisenbahn - Wiederinbetriebnahme PZB / LZB (Vectron)

This video shows how to restart the PZB/LZB after it has been shut down by activating the fault switch(es). It's actually quite simple, but there can be a pitfall that occasionally leads to delays, as this situation, although rare, sometimes goes unnoticed. A locomotive may be taken over after a workshop visit or a deployment abroad with the PZB/LZB shut down. The fault switches are usually simply reset, and everything is fine. However, if the PZB/LZB air shut-off valve has also been closed, this can easily be overlooked. Unfortunately, a shut-off PZB/LZB air shut-off valve usually does not generate a separate error message. However, it can be identified by the following symptoms: No indicator light (LM) on the PZB flashes to prompt for train data entry. The 1000 Hz light flashes even though sufficient pressure has been built up in the main air line. On the Siemens BR 193 shown here with Baseline 3 configuration, the picture is slightly different in ETCS OFF mode. Nevertheless, it is still possible to see what needs to happen for the train to operate in PZB/LZB mode. Bonus: The video shows the corresponding shut-off valve. It is installed in a way that is otherwise rather unusual for locomotives. My railway books on Amazon: https://www.amazon.de/stores/author/B...
