What is causing this error?

It's most likely an AIL issue. Check your Air-in line sensor cables on the backside of the MEA board. Sometimes they get caught in the housing when they get put back together and the cables can get cut/shorted causing this error on power up, or the sensor itself (inside the AIL housing) could possibly be going bad.
Also, we repair/service and sell parts for Medsystems at Biomedix Medical. Feel free to call us for help or parts 610-268 -1444
