Not Lit Not Lit Not Lit Not Lit Power OFF
The drive is not powered.
Check the drive main circuit wiring,
and then turn ON the power.
The option is not correctly
connected, thus, the power does not
supply to the option. Turn Off the drive power, check the
connection of the option and the drive,
and re-power the drive.

Possible Fault
A wrong setting of a switch or a
recovery fault is occurring.
Check baud rate setting (DIP switch,
