(b) Abnormal end
The ERR. LED starts flashing upon error detection during the diagnostics and
setting, and the LEDs turn on corresponding to the diagnostics or setting of the
error.
Upon detection of the failure, the diagnostics and setting will be terminated.
* 1 An error may occur if a CompactFlash card is not inserted.
Insert a CompactFlash card and then reexecute the self-diagnostic test for Mode 2.
* 2 An error may occur if a self-loopback distribution cable is not connected correctly.
Correctly connect and distribute the cable again, and then reexecute the self-diagnostic test for
Mode 3.
Retry the diagnostics and setting if it failed.
If the error recurs, hardware fault of the C Controller module may be the cause.
Please consult your local Mitsubishi representative, explaining the details of
the problem.
