36 ERROR CODES
36.4 List of Error Codes
3C10H Hardware failure • A hardware failure has been detected. Stop ■CPU module
• Take measures to reduce noise.
• Check the mounting status of the
CPU module.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
cause is a hardware failure of the
CPU module. Please consult your
local Mitsubishi representative.
■Redundant function module
• The possible cause is malfunction
due to noise. Take measures to
reduce noise by checking the
distance of wires and cables, and
the grounding status of each
device.
• Execute a module communication
test. If the same error code is
displayed again, the possible
cause is a hardware failure of the
redundant function module.
Please consult your local
Mitsubishi representative.

3C12H Hardware failure • The waveform of the voltage out of
the specified range has been
detected in the power supply module.
• A hardware failure has been detected
in the power supply module, CPU
module, base unit, or extension cable.
(In a redundant power supply system,
the error is detected when two power
supply modules failed.)
Stop • Check the waveform of the
voltage applied to the power
supply module.
• Check the mounting status of the
CPU module.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
cause is a hardware failure of the
power supply module, CPU
module, base unit, or extension
cable. Please consult your local
Mitsubishi representative.
