Steam Dgs 69271 (öbb 1116) - How I'm Supposed To Pass This Signal?

Hello, can someone please tell me how to pass this signal? From what I understand, it means I should go slowly, but I can't pass it at all without being automatically stopped right away. I've tried several options and pressed various things like PZB Release and Acknowledge before and after passing it, and nothing works. I even watched videos where a player had the same signal and passed it completely normally without any problem. He did have a Vectron and not the ÖBB 1116 like I do in the video, but that shouldn't make a difference, right? I'm really at a loss here. Can anyone help me? I managed to pass it once, but I have absolutely no idea how...

Bump, because it had to be approved by the moderators for some reason and got lost among the new posts.

 

Press the PZB override as you pass the signal and you will be fine. That happens because although the two white dots permit you to do the manuevers, the PZB will read the red signal and activate if you don't press the PZB override. Hope that help
