Q1043 is pointing to Oil Lubrication motor breaker. You can find it inside the main electric cabinet.
About the safety cover, there might be a damaged DIPM2 in Delivery which is very common issue.
Yes, in the back of Delivery panel. There are two LEDs above CANBUS cables (purple cables). Take s short video. I need to see the LEDs status.
Did you check if Q1043 is tripped?
You didn't say anything about the machine age!!!
A picture of the panel actually help, not really sure if there is a DIPM or just EAK's, could be blown fuses at the power distribution board inside the cabinets, like I said a picture would help.
