Hi Everyone!

We have an M-20iA with R-30iB controller which we didn’t use in a while. It was placed in workshop now we needed this bad boy but all it is showing is errors. Below spot errors are i am currently having:

SPOT-474 NM & OUT 24v shorted after MCC

SPOT-476 Fix Power short & then cycle

All wires and boards are seem fine. There's no detail about these spot errors in the manual. Can someone Help me with these?

    Hello Friend ,

    Looks like 24V output fuse is blown. Check all fuses FS1 FS2 FS3 fuse. You can use multimeter , Check with continuity function.

    I think from the error description, It must be related to power shortage . Kindly check if you are getting enough power , If not use stepup transformer.
