List of Error Codes

If an error occurs in operation of the temperature control module, the error code of the error is stored into 'Latest error code'
(Un\G0) of the buffer memory and 'Error flag' (X2) turns ON. In addition, an error address is stored in 'Error address' (Un\G1).
Turning ON 'Error reset command' (Y2) clears the error code in 'Latest error code' (Un\G0), and 'Error flag' (X2) turns OFF.
Error codes of the temperature control module are classified into minor errors or moderate errors.
• Minor error: This error is caused by setting failures of programs or parameters, or incorrect execution timing. After the error
cause is eliminated as a result of reviewing programs, each function can be normally executed. (1000H to 1FFFH)
• Moderate error: An error such as a hardware failure. The module does not continue the temperature control. (3000H to
3FFFH)
The following table lists the error codes to be stored.
 in error codes: This symbol indicates the number of the channel where an error has occurred. (1: CH1, 2: CH2, 3: CH3, 4:
CH4)
 in error codes: For what this symbol indicates, refer to the Description and cause column.

3.4 List of Error Codes
Description and cause
A value other than 0 and 1 has been stored in Interrupt
factor generation setting [n].
 indicates that the interrupt setting corresponding to the
error is as follows:
0: Setting 1 to F: Setting 16
A value other than 0 to 12 has been stored in Condition
target setting [n].
 indicates that the interrupt setting corresponding to the
error is as follows:
0: Setting 1 to F: Setting 16
A value other than 0 to 4 has been stored in Condition
target channel setting [n].
 indicates that the interrupt setting corresponding to the
error is as follows:
0: Setting 1 to F: Setting 16
Writing a value to the area where writing is allowed only in
the setting mode was attempted in the operation mode.
The current control mode is different from the one backed
up in the non-volatile memory because the control mode
was changed.
The current control output cycle unit is different from the
one backed up in the non-volatile memory because the
control output cycle unit was changed.
The current sampling cycle is different from the one
backed up in the non-volatile memory because the
sampling cycle was changed.
The setting value has been changed while 'Default setting
registration command' (Y9) is ON.
Data out of the setting range is being written.
The value set in CH Lower limit output limiter is equal to
or greater than the value set in CH Upper limit output
limiter.
The value set in CH Lower limit setting limiter is equal to
or greater than the value set in CH Upper limit setting
limiter.
Corrective action
Set Interrupt factor generation setting [n] to 0 or 1.
Set Condition target setting [n] to a value within the range
of 0 to 12.
Set Condition target channel setting [n] to a value within
the range of 0 to 4.
Follow the instructions below to reset the error.
1: Change the mode to the setting mode.
2: Set the correct value and turn ON and OFF 'Setting
change command' (YB).
When switching the mode from the operation mode to the
setting mode, check that PID continuation flag is Stop (0),
and turn from ON to OFF 'Setting/operation mode
command' (Y1).
Turn ON and OFF 'Setting value backup command' (Y8).
After turning ON and OFF 'Error reset command' (Y2),
change the setting value.
*1
Set data within the range.
Set the value so that the upper limit value is greater than
the lower limit value.
Set the value so that the upper limit value is greater than
the lower limit value.
