• A malfunction may have occurred due to noise. Check the wire and cable
distances and grounding condition of each device, and take measures
against noise.
• Execute hardware and self-loopback tests. If a failure occurs again, the
hardware of the master/local module may be faulty. Please consult your
local Mitsubishi representative.
