ERROR CODE DISPLAYS AND POINTS TO REMEMBER
WHEN TROUBLESHOOTING
3. Points to remember when troubleshooting
1) Points to remember if abnormality returns to normal by itself:
If the connector is disconnected and the T-adapter is inserted, or if the T-adapter is removed and the
connector is returned to its original position when carrying out troubleshooting of the failure, and the
error code is no longer displayed, or the [
E
] for the error code is no longer displayed, the abnormality
has probably returned to normal.
However, there is a high probability that the same problem will occur again, so it is desirable to follow up
this problem carefully.
2) Handling error code:
When carry out troubleshooting after displaying the error codes, save all the errors that have been dis-
played, then delete them. Following this, try to re-enact the problem and carry out troubleshooting for
the error codes that are displayed.
★ Among the error codes that are saved, there are some that were caused by mistaken operation or
when the connectors were disconnected, so re-enacting the failure prevents time from being wasted
on unnecessary checks.
After completing troubleshooting, erase all the error codes.
3) Handling connectors
★ Before starting troubleshooting, check that the connectors related to the error code are properly in-
serted.
★ Always connect any disconnected connectors before going on the next step or after completing trou-
bleshooting.
