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,
explaining a detailed description of the
problem.)
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, explaining a detailed
description of the problem.)
