and then OFF again, then replace the Unit.
3-7-5 Troubleshooting
The following tables explain the probable causes of troubles that may occur, and
the countermeasures for dealing with them.
Probable Cause Countermeasure Page
The output is not set for being
used.
Set the output for being used. 50
The output hold function is in
operation.
Turn ON the Output Conversion
Enable Bit.
52
The conversion value is set outside
of the permissible range.
Set the data within the range. 39
Probable Cause Countermeasure Page
The output signal range setting is
wrong.
Correct the output signal range
setting.
50
The I/O specifications of the output
device do not match those of the
Analog Output Unit (e.g., input
signal range, input impedance).
Change the output device. 38
The offset or gain is not adjusted. Adjust the offset or gain. 54
Probable Cause Countermeasure Page
The output signals are being
affected by external noise.
Try changing the shielded cable
connection (e.g., the grounding at
the output device).
44
Analog Output Does Not
Change
Output Does Not Change
as Intended
Outputs are Inconsistent
