3.4 List of Error Codes
Description and cause
An invalid value is set for the offset/gain setting of
CH.
The offset value and gain value to be saved in the
flash memory are as follows:
Gain value - Offset value  0.1
A value other than 0 and 1 is set in CH Offset/gain
setting mode (offset specification) and CH Offset/
gain setting mode (gain specification).
The offset temperature setting value and gain
temperature setting value are as follows:
Gain temperature setting value - Offset temperature
setting value  0.1
The channel where disconnection has occurred or
channel where the conversion is disabled is
specified when Channel change request (YB) has
been turned on.
The offset temperature setting value or gain
temperature setting value for the specified channel
is out of the measuring range when Channel change
request (YB) has been turned on.
A hardware failure (minor) has occurred in the
module.
A hardware failure (moderate) has occurred in the
module.
The data in the flash memory is abnormal.
Action
Perform the offset/gain setting again for the
channels where the error has occurred.
If the error occurs again, the possible cause is a
failure of the module. Please consult your local
Mitsubishi representative.
Perform the offset/gain setting again so that the
following condition is satisfied:
Gain value - Offset value > 0.1
Set 0 or 1 in CH Offset/gain setting mode (offset
specification) and CH Offset/gain setting mode
(gain specification).
Perform the offset/gain setting again so that the
following condition is satisfied:
Gain temperature setting value - Offset temperature
setting value > 0.1
Check wiring for disconnection, or specify the
channel where the conversion is enabled.
Set a value within the measuring range as the offset
temperature setting value or gain temperature
setting value for the specified channel.
The module may be affected by noise. Review and
adjust the cable wiring and the installation
environment of the programmable controllers. After
the adjustment, turn on and off Error clear request
(YF) to eliminate this error and resume the
conversion.
If the error occurs again, the possible cause is a
failure of the module. Please consult your local
Mitsubishi representative.
Power off and on the module. If the error occurs
again, the possible cause is a failure of the module.
Please consult your local Mitsubishi representative.
Check measured temperature values. If the values
are abnormal, please consult your local Mitsubishi
representative.
