I managed to turn on LZB/PZB in the regular mode (opposed to expert mode), flipping the breaker and I found the value to enable, but in regular mode SIFA doesn't enable even with the breaker closed and the value opened. I even put in train data and it didn't work. Looked through the whole manual and can't find anything else. Am I missing something?
Have you made sure that the Sifa isolation switch is in the normal/enabled position? It is a small black switch on the cab 2 side of the machine room, right by the "ZDE Voltage Source" switch. Like PZB/LZB, Sifa has 3 necessary conditions for running: air valve open, LSS main breaker closed and Isolation switch/button disengaged.
