Check item Corrective action
Check that five seconds have passed since the power supply module is
powered off.
After the power supply module is powered off, wait at least five seconds
before turning on the input power supply to the power supply module.
Check item Corrective action
Check whether the R60AD8-G is in standard mode and in offset/gain setting
mode.
Check the module configuration diagram of GX Works3. When the module
configuration diagram of GX Works3 is "R60AD8-G", the R60AD8-G is
operating in standard mode and in offset/gain setting mode. Change the two
R60AD8-G modules to those in SIL2 mode ("R60AD8-G (S2M)" and
"R60AD8-G (S2S)").
Check item Corrective action
Check whether the power is supplied. Check that the supply voltage of the power supply module is within the rated
range.
Check whether the capacity of the power supply module is enough. Calculate the current consumption of the mounted modules, such as the
remote head module, I/O modules, and intelligent function modules, to check
that the power capacity is enough.
Check whether the modules are mounted properly. Check the mounting state of each module.
Cases other than the above Reset the remote head module and check that the RUN LED turns on.
If the RUN LED still remains off, the possible cause is a failure of the module.
Please consult your local Mitsubishi representative.
