This function diagnoses that the duplicated input device states are matched.
This function diagnoses that the input circuit and the externally connected machine
are not fixed to on.
This function diagnoses that the output circuit and the externally connected
machine are not fixed to on.
This function diagnoses that input devices are not fixed by repeatedly turning the
devices on and off individually when the power to MR-D30 is switched on.
