Troubleshooting

   

                                                      

 

    Model: T645

    Malfunction: ERROR_8_2_ 

Circumstance: In operation, the display shows ERROR_8_2_. 

    Possible cause: 1. Interference disrupts communication between the display 

                                    and EAC drive board. 

    Troubleshooting: 1. Inspect cable connections between the display and 

                                        drive boards. 

                                  2. When this error appears, re-start the unit. Sometimes, re-starting 

                                      the unit restores normal communication and operation. 

                                  3. If re-starting the unit does not eliminate ERROR_8_2_, replace 

                                      the EAC drive board.
