Description and cause
CH Scaling upper limit value and CH Scaling
lower limit value are set as the scaling upper limit
value = the scaling lower limit value.
A value other than Enable (0) and Disable (1) is set
in CH Warning output setting (Process alarm).
The values set in CH Process alarm upper upper
limit value to CH Process alarm lower lower limit
value do not satisfy the following condition:
Upper upper limit value  Upper lower limit value 
Lower upper limit value  Lower lower limit value
 indicates that the set values are as follows:
1: Process alarm lower lower limit value > Process
alarm lower upper limit value
2: Process alarm lower upper limit value > Process
alarm upper lower limit value
3: Process alarm upper lower limit value > Process
alarm upper upper limit value
A value other than Enable (0) and Disable (1) is set
in CH Warning output setting (Rate alarm).
A value other than 1 to 32000 is set in CH Rate
alarm warning detection cycle setting.
CH Rate alarm upper limit value and CH Rate
alarm lower limit value are set as Lower limit value 
Upper limit value.
A value out of the range is set in CH Input signal
error detection setting.
A value other than 0 to 250 is set in CH Input
signal error detection setting.
Simple disconnection detection is set in CH Input
signal error detection setting, and the value set in
CH Input range setting is set to anything other
than 4 to 20mA (extension) (AH).
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
Set CH Scaling upper limit value and CH Scaling
lower limit value as the scaling upper limit value 
the scaling lower limit value.
Set CH Warning output setting (Process alarm) to
Enable (0) or Disable (1).
Set CH Process alarm upper upper limit value to
CH Process alarm lower lower limit value so that
the values satisfy the following condition:
Upper upper limit value  Upper lower limit value 
Lower upper limit value  Lower lower limit value
Set CH Warning output setting (Rate alarm) to
Enable (0) or Disable (1).
Set CH Rate alarm warning detection cycle setting
to 1 to 32000.
Set CH Rate alarm upper limit value and CH
Rate alarm lower limit value as Lower limit value <
Upper limit value.
Set CH Input signal error detection setting to
Disable (0) to Simple disconnection detection (4).
Set CH Input signal error detection setting to 0 to
250.
For channels where simple disconnection detection
is performed using the input signal error detection
function, set CH Input range setting to 4 to 20mA
(extension) (AH).
The module may be affected by noise. Check 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 clear the error or restart the conversion
operation.
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 the digital output values.
If the values are abnormal, please consult your local
Mitsubishi representative.
