Troubleshooting
I-Max Touch 8-15
8.2.3.5. E362: X-ray button released during the examination procedure
X-ray emission is commanded using the technique called "dead man’s
switch", which means that it must be held pressed down until the end of
the emission, also during the interrupted emission phase of TMJ.
If this does not happen, the above error message is displayed; the
emission is stopped and all motors released in order to allow for the
patient’s exit.
Press the reset button and restart the operation as suggested by the
control system.
8.2.3.6. E380: Invalid CANBus message (from Generator CPU board A9)
This error is displayed when the main CPU board (A5) receives an invalid
message from the Generator board (A10); that is a message which
contents is not listed on the valid data dictionary of the unit.
This can be generated by a bad connection or by a fault of the local
Generator CPU board (A9).
Check the CANBus cable X20-X20 and replace it if faulty, otherwise
replace the Generator CPU board.
8.2.3.7. E381: Timeout on activating CAN protocol on Generator board /
E382: HF not answering to CAN protocol
These two messages have the same meaning, that is a no answer to main
CPU (A5) from CAN messages, but their occurring is in different times.
E381 is generated during power on, while E382 is displayed after a
regular power on sequence.
In both cases, the error can be generated by a bad connection of the
CANBus or a fault on the local Generator CPU board, so the steps above
described for E380 are applied.
