How to view the error result
The following screen is an enlarged view of the detailed information indicated above.
Explanation of the detailed error information is described.
[NO] means that optional PCBs are not mounted.
A fault has occurred when [NO] is displayed irrespective of whether the Option PCB is attached.
[NG] means that an error occurred to PCBs mounted as standard.
■ Controller Self Diagnosis Table
