Problem
Assumed cause
Correction
The disconnection indication does not clear. An output device is dis-
connected.
Restore the output device connec-
tion.
Check the output device and input
type.
The input is significantly
out of the output device
measurement range.
Check that the input is correct.
Wiring is incorrect. (Posi-
tive and negative are re-
versed etc.)
Check that the wiring is correct.
The user calibration error
is too large.
Execute the user calibration again.
The disconnection detection is not per-
formed.
The input range is not set
to 1 to 5 V or 4 to 20 mA.
Check the input range.
The line disconnection de-
tection is disabled.
To use the line disconnection detec-
tion, set the Disconnection Detection
Enable/Disable setting to Enable.
The user calibration is not accepted.
An attempt was made to
make calibration with in-
puts outside the correc-
tion range.
Input the voltage/current within the
correction range from the input de-
vice and make the calibration again.
If the voltage/current within the cor-
rection range cannot be input,
change the connecting method to the
input device.
Although the external device connected to
the trigger input terminal is ON, nothing is
input and the IN indicator is not lit either.
The I/O power is not sup-
plied.
Check that the I/O power is supplied.
The I/O power supply volt-
age is outside the rated
range.
Set the I/O power supply voltage
within the rated range.
The Unit is not wired cor-
rectly with the connected
external device.
Check the wiring with the connected
external device.
The wiring to the connect-
ed external device is dis-
connected.
Check the wiring with the connected
external device.
A connected external de-
vice is defective.
Replace the connected external de-
vice.
There is a problem with
the Unit.
Cycle the power supply to the Unit.
If the problem persists even after the
power supply is cycled, replace the
Unit.
The High-speed Analog
Input Unit is not installed
in the upright orientation.
The High-speed Analog Input Units
can be installed only in the upright
orientation, regardless of the destina-
tion to which they are connected. In-
stall the High-speed Analog Input
Unit in the upright orientation.
A Relay Output Unit (NX-
OC
££££
) is connected
next to the High-speed
Analog Input Unit.
Do not connect a Relay Output Unit
(NX-OC
££££
) next to the High-
speed Analog Input Unit.
