Hello,
2 Days ago I was adding a timer on a Modicon Quantum 113/03 using Proworx. I forced the contacts on the shutdown logic of a compressor, to edit on the coil of the same contact. It was a LSHH. The problem was that, even though the contact on the shutdown logic was forced, when I erased the coil, the force in the contact was removed automatically. That executed a shutdown sequence on the 2 compressor that work on cascade.
Later I did the same thing with many contacts/coils to reproduce the event, and it worked the same.
Is it normal? Has this thing happened to any of you? Is it something I'm missing?
I will appreciate your help on this, because, to the best of my knowledge, this shouldn't have happened.
Thanks in advance.
