detection error
1EFH A/D conversion circuit
diagnostic error
3001H Hardware failure
3020H Safety mutual monitoring
error
3050H Safety parameter error
3060H Module configuration error
*1 The error can be cleared by i_bUnitErrClear (module error clear) of the SIL2 safety program FB. If an error is displayed, change the
module parameter and enable the safety module again.

14.6 List of Error Codes
Error description and cause
The discrepancy of double input was
*1
detected.
An error was detected with the A/D
conversion circuit diagnostics.
A module hardware failure was detected.
An error was detected in the counterpart
device that is mutually monitored.
An error of safety parameter was detected
at the startup of the system.
An error was detected with the
configuration check for operating the
R60AD8-G in SIL2 mode.
Action
Identify the channel with an error by the status code of the SIL2
diagnostic FB library, and check the connected devices and
wiring.
If connected devices and wiring are correct, there may be an
influence from noise or module failure. If measures to reduce
noise do not eliminate this error, the possible cause is module
failure. Please consult your local Mitsubishi representative.
There may be an influence from noise or module failure. If
measures to reduce noise do not eliminate this error, the
possible cause is module failure. Please consult your local
Mitsubishi representative.
Turn off and on the power supply of the module.
If the same error occurs again, the possible cause is module
failure. Please consult your local Mitsubishi representative.
A moderate error was detected in the counterpart device that is
mutually monitored. Check the error code on the counterpart
device side, and take an action corresponding to the error code.
If a safety mutual monitoring error occurs in both modules, this
indicates that either module is in failure but the failed module
cannot be identified. Identify the module in failure by replacing
each module one by one with a normally operating module, and
consult your local Mitsubishi representative.
The possible cause is a failure of safety parameter write. Write
the safety parameter to the module again with GX Works3.
If the same error occurs again even after the parameter has
been set again, the module may be in failure. Please consult
your local Mitsubishi representative.
Review the configuration for operating the R60AD8-G in SIL2
mode.
If the same error occurs again even after the module
configuration review, the module may be in failure. Please
consult your local Mitsubishi representative.
