I purchased a used non-working Hardinge HLV-H #6815 P 230Vac 3 phase Machine. After 2 months of self study on the forum, cleaning and Transformer replacement it runs very well. However; One last thing to trouble shoot is the power feed control box. I need ask for a little help..
The switch Right/Stop/Left worked fine, but no speed adjustment from the amber colored (Potted?) rheostat. I am suspecting a couple wires could be in the wrong location. I did find wires that do not match the rest.
I am hoping someone can take 3 pictures of their working non-modified feed controller box wiring and post them for comparisons and reference. Once I can verify the wires are in the right location, I will know the operational status. I'm unable to locate the stock wiring diagram KLC-8220 anywhere, including from Hardinge. All the diagrams I have seen are for the Modifications to add bridges. I need to see if it works in stock configuration, before I make modifications or replace.
example
The rheostat 120volt input is on terminals L1, L2 works. Terminal S1 has wire #21. Terminal F1 has wire F1 and #20 Terminal F2 has #23 only (Wire F2 is one of the wires in question) some simple pictures would be a great reference.
