391CH to
391FH Setting and diagnostic
error Setting and diagnostic error occurred. Check the setting and wiring, and reset the power of the whole
system.
If the error is not resolved, there is a possibility that the module is
malfunctioning.
Please contact your local Mitsubishi Electric sales office or
representative.
3921H Setting and diagnostic
error Setting and diagnostic error occurred. Check the setting and wiring, and reset the power of the whole
system.
If the error is not resolved, there is a possibility that the module is
malfunctioning.
Please contact your local Mitsubishi Electric sales office or
representative.
3922H Setting and diagnostic
error Setting and diagnostic error occurred. Review the system configuration, check the setting and wiring, and
reset the power of the whole system.
3941H to
3942H Setting and diagnostic
error Setting and diagnostic error occurred. Check the setting and wiring, and reset the power of the whole
system.
If the error is not resolved, there is a possibility that the module is
malfunctioning.
Please contact your local Mitsubishi Electric sales office or
representative.
3981H Number of connected
modules excess error The modules exceeding the maximum
number of connectable modules are
detected. Configure a system using the predefined number of safety extension
modules or less.
3982H Setting and diagnostic
error Setting and diagnostic error occurred. Check the setting and wiring, and reset the power of the whole
system.
If the error is not resolved, there is a possibility that the module is
malfunctioning.
Please contact your local Mitsubishi Electric sales office or
representative.

3A01H to
3AFFH Each of the following bits indicate an error.
3A
 H
Lower bits: Logic path A (0: no error, 1: with error)
• b0: Bit for input logic error
• b1: Bit for start function logic error
• b2: Bit for output logic error
• b3: Bit for bypass error
Upper bits: Logic path B (0: no error, 1: with error)
• b4: Bit for input logic error
• b5: Bit for start function logic error
• b6: Bit for output logic error
• b7: Bit for bypass error
Check the wiring of inputs for the corresponding logic paths.
3B01H I0/I1 synchronization
time/concurrence error A synchronization time/concurrence error
occurred in I0/I1. Inconsistency in the double input state is detected.
Turn the input signals I0/I1 OFF and ON again.
If the error is not resolved, check the wiring of the corresponding
input terminals.
3B02H I0/I1 process error A process error occurred in I0/I1. Inconsistency in the double input state is detected.
Turn the input signals I0/I1 OFF and ON again.
If the error is not resolved, check the wiring of the corresponding
input terminals.
3B03H I0/I1 cross-circuit error A cross-circuit error occurred in I0/I1. A cross-circuit is detected in the double input state.
Turn the input signals I0/I1 OFF and ON again.
If the error is not resolved, check the wiring of the corresponding
input terminals.
