– Check the network parameters and actual
mounting status, and if they differ, make them
match.
When network parameters are modified, write
them to the CPU module.
– Check the setting of extension base unit stage
number.
– Check the connection status of extension
base unit and extension cables. When the
GOT is busconnected to the main base unit or
extension base unit, also check its connection
status.
If the error occurs even after the above checks,
the possible cause is a hardware fault.
Contact your local Mitsubishi representative.
