Hi

  • Priyanshu,
    The weld detection circuit was implimented in the schematic, but was outside the scope of the origional design intent and wasn't fully validated. It's a simple arrangment to only detect if there is AC voltage on the other side of the contactor. As this is now a relativly old design, I would recomend finding a more advanced method of weld detection to utilize.
