I have some trouble with a RR5200 model. Sometimes i have the message ­­''access bar'' or ''foot right'' and the machine not start. I switch the floor with and other and it's OK! And sometimes i have ''stand by'' message with the mechanical key hilight. The fuse F10 have blown a few times. We have check voltage, harness, plugs, etc... and we have had an event code 417. The next step is to change the TDM. Have you ever had this problem?
