(5) Base I/O unit related
The external power supply turns ON, but the base I/O unit power does not turn ON.
Cause
Remedy
The external power supply output
is not correct.
Check that the output voltage is 24VDC±5% at the
connector end on the base I/O unit side.
The 24VDC power supply cable is
disconnected or broken.
Correctly insert the connector in the base I/O unit. Check the
cable wiring.
The cable connected from the
base I/O unit to the peripheral
device is short-circuited.
Disconnect the cables connected to the peripheral device
one at a time, and check that the power turns ON. Check
whether any of the cables are short-circuited.
The base I/O unit is faulty.
Confirm that the base I/O unit's LED "5OUT" (green) lights
when the cables connected to the peripheral devices are
disconnected. If the "LED 24IN" (green) turns ON and
"5OUT" remains OFF, the internal power supply circuit may
be faulty.
The base I/O unit power turns ON, but the machine input/output signals cannot be input/output.
Cause
Remedy
The power for the machine
input/output signals is not
supplied.
The base I/O unit's control power and the machine
input/output power are separated. The machine input/output
power must be supplied separately.
The F351 cable is not connected
to the CF31 to CF34 connectors,
or the connection connector is
incorrect.
Check the cable wiring.
The sink/source connection is
incorrect.
The base I/O unit has the FCU6-HR341/DX220,etc. sink
connection and FCU6-HR351/DX221,etc. source
connection.
Others
The base I/O unit may be faulty.
The communication error LED "RAL1" or "RAL2" (red) is lit.
Cause
Remedy
The remote I/O cable
(FCUA-R211, SH41) is not
connected or is broken.
Check the cable wiring.
The station No. setting for the
remote I/O unit connected to the
base I/O unit is incorrect.
Station Nos. 0 and 1 are used by the base I/O unit, so set the
remote I/O unit to station Nos. 2 to 7.
Others
The base I/O unit may be faulty.
