Technical manual Planmeca PlanMill 40 85
2.2 Troubleshooting firmware update requiring warning
Figure 66: Firmware update warning
Causes
• This error is most often caused by failure of one of the circuit boards in the CPU
module.
• This error is less often caused by a failure of the accelerometer processor board.
Other contributing factors
• This error is rarely caused by a disconnected or bad USB cable from the
accelerometer processor board to the electronics box.
Solutions
• Shut down the milling unit and power it off.
• Locate the USB cable, which connects from the accelerometer processor board to the
electronics box.
• Unplug the 90 degree connector of the USB cable from the back of the electronics box
and plug it into the lower USB port on the lower electronics box.
• Power the milling unit on and see if the error message reoccurs.
• If the error message reoccurs, power down the mill and plug the 90 degree connector
of the USB cable into the other USB port on the lower electronics box.
• Power the milling unit on and see if the error message reoccurs.
• If using one of the two USB ports on the lower electronics box eliminates the error
message then replace the CPU module.
• If using neither of the two USB ports on the lower electronics box eliminates the error
message then replace the accelerometer processor assembly.
