Hello, I'm looking to hopefully get some help diagnosing a Siemens 840D NCU that we just replacement. The board number is 6FC5357-0BB33-0AE1 and when we installed it, the 7 segment display gave us a 1-0-9 error. It also gave us a static "3" at one point, and I can't seem to find anything in the manual that shows the different meanings of these codes. I found something saying that a 6 was the ready state, but nothing about these other readings. Any help would be appreciated.
