Corrective action
• Remove the CPU module from the main
base unit if it does not support a multiple
CPU system configuration. Alternatively,
replace the CPU module that does not
support a multiple system configuration
with the one that does.
• The cause is a failure of the intelligent
function module, CPU module, or base
unit. Please consult your local Mitsubishi
representative.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a failure of the intelligent function
module, CPU module, or base unit. Please
consult your local Mitsubishi
representative.
• Reconfigure the control CPU setting of
other CPUs so that it can be the same as
that of CPU No.1.
• Remove the CPU module from the main
base unit if it does not support a multiple
CPU system configuration. Alternatively,
replace the CPU module that does not
support a multiple system configuration
with the one that does.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a failure of the intelligent function
module, CPU module, or base unit. Please
consult your local Mitsubishi
representative.
