Apologies if this is not the right thread.
We have an old VMC 610 Fanuc 6M we are trying to get operational and have most recently received error code 81, which according to the Electric Circuit Maintenance Sheet means: "The ATC pot guide advance end limit switch (LS 19) does not become ON." I cannot find LS19 on the machine, and eveb Enshu support has been unable to provide me with its physical location on the machine. Help in finding this switch and/or resolving this problem would be greatly appreciated.
