Corrective Action
Check the condition of the other
stations.
• Check the CPU module or tracking
cable. If the error still occurs, this
indicates the CPU module or
tracking cable is faulty. (Contact
your local Mitsubishi representative,
explaining a detailed description of
the problem.)
• Confirm the redundant system
startup procedure, and execute a
startup again.
