13.2 Troubleshooting
13.2.1 Indication of "FAILURE" LED
The
flashing pattern of the
"FAILURE" LED (red) differs depending on the type of
abnormality/error. When two or more failures are detected simultaneously, a
high-priority failure is indicated. Also, the failure signal is output from the "X2
REMOTE" connector.
If an abnormality/error is found, take measures in accordance with Table 13.2.
