13-9 Troubleshooting Other Errors
This section describes error symptoms that cannot be resolved with the methods for checking for errors
and troubleshooting that were described earlier.
Status
Possible cause and correction
When the Unit configuration was
registered, the TS indicator on the
EtherCAT Coupler Unit flashed
green, and the TS indicators on the
first few NX Units near the EtherCAT
Coupler Unit flash green and the TS
indicators on the other NX Units are
not lit.
The NX bus connector on the left side of the Units where the TS indica-
tors are not lit is not connected properly.
Connect it properly and cycle the power supply.
• All TS indicators on the EtherCAT
Slave Terminal (EtherCAT Cou-
pler Unit and NX Units) are lit
green.
• When the output of the EtherCAT
Coupler is active, the OUT indica-
tor on the Digital I/O Unit is lit yel-
low but the actual output is OFF.
• A device (e.g., sensor) that is con-
nected to the Digital I/O Unit is
ON, but a signal is not input, and
the IN and OUT indicators are both
not lit.
• The power supply to the Additional NX Unit Power Supply Unit is not
turned ON. Check the wiring and turn ON the power supply.
• The NX bus connectors between the Units are not connected properly.
Make sure that the Unit hookup guides are properly engaged.
• The wiring for the I/O power supply is disconnected. Check the wiring.
