* Do not short-circuit the automatic address setting pin (CN51) again while automatic address set-
ting is in progress. Doing so will cancel the setting operation and will cause LEDs 1 and 2 to turn
OFF. (LED 1 is D042. LED 2 is D043.)
* When automatic address setting has been successfully completed, both LEDs 1 and 2 turn OFF.
If automatic address setting is not completed successfully, refer to the table below and correct the
problem. Then perform automatic address setting again.
