Error Codes Related To The Safety Remote I/O Module - Mitsubishi Electric NZ2GFSS2 32D S1 User Manual

Error codes related to the safety remote I/O module

Errors of the safety remote I/O module are classified into the following three types.
*1
Error status Description
Major error Error because of which the module stops, such as hardware failure. The safety functions (safety I/O, safety diagnostics, and safety
communications) stop.
Moderate error Error because of which the module stops, such as a parameter error related to module operation. The safety functions (safety I/O, safety
diagnostics, and safety communications) stop.
Minor error Error after which the module continues its operation, such as double input discrepancy detection. The safety functions keep operating.
*1 When multiple errors have occurred, the error statuses are displayed in the order of error severity (Major error > Moderate error > Minor
error).

Error name Description and
cause
Hardware failure A hardware failure
was detected.
Self-diagnostic An error was
error detected by the self-
diagnostics.
Output overload The overcurrent
error protection or
overheat protection
of the output circuit
was activated.
External power An external power
supply voltage supply error was
error detected.
Module The module
configuration configuration has
changed been changed after
power on.
Action
There may be an influence from
noise or a hardware failure. If the
same error occurs again even after
measures have been taken against
noise, the module may be in
failure. Please consult your local

Mitsubishi representative.
• Review the connected devices
and wiring.
• When the connected devices
and wiring have no errors, there
may be an influence from noise
or a hardware failure. If the
same error occurs again even
after measures have been taken
against noise, the module may
be in failure. Please consult your
local Mitsubishi representative.
• Match the ON timing of the
external power supply with the
ON timing of the module power
supply.
• Review the connected devices,
wiring, and voltage.
• There may be an influence from
noise of external wiring (such as
power supply part and I/O signal
part). Take measures to reduce
noise.
• If the same error occurs again,
the module may be in failure.
Please consult your local
Mitsubishi representative.
• Check the connection status of
the extension module.
• If the module is connected
properly, there may be an
influence from noise or a
hardware failure. If the same
error occurs again even after
measures have been taken
against noise, the module may
be in failure. Please consult your
local Mitsubishi representative.
