I have a code 47. Fellow tech ordered a carriage manager and display card and the cable assy between the two components. Powered up had to calibrate then the code 47 again. I was told it coded after a bump in the floor was hit. Manual says to replace the parts I just replaced.
Could the mast cables cause this? I'm just guessing now since the problem parts were eliminated.

With the three error codes they all have to do with communications in one form or another. I would start with checking your bus lines for opens or shorts. Between all systems.
