    Default HLV-H Electrical Control Box Pics Please “Inside pics”

    I was wondering if someone could post
    a pic or two of the inside of the
    control boxes and maybe help me point
    out some differences in my box.
    I have a BIG box on the back and a
    small box on the left side also. Most
    of the ones I have seen are on the
    left side and I want to move it all
    down to the left side like most of the
    one’s I’ve seen for more than one reason
    but a big reason is to have a proper
    chip shield on the back, and I think
    it just looks ugly etc. I guess I could
    go on but you get it.
    I’d like to get everything on the
    inside in the proper place but often
    times things are better placed by
    end users. So I’d like to know if
    most everything is the same from one
    machine to the next that have the same
    options anyway. Thanksdac21a7e-b195-46ba-b096-add01e87d90a.jpg0b7324c8-cfd1-4505-a50d-f161bc51fadd.jpg

    Sorry the pics are sideways to the left, if someone
    could fix that I’d appreciate it. I took the pics
    with the camera upright, instead of on the side so I
    don’t know why they keep ending up like that.

    You should find serial # and then get the machine year.
    You should also find the electrical diagram number and voltage(s) of your machine. (Should be on the outside of the electrical cabinet)
    Call Hardinge with this info.

    The plate should look like this:



    Mine both claim they are wired 480V-ish.
    Here’s the inside of a cabinet:


    I have a couple of diagrams, but GE Labs altered the wiring a bit on mine to add a receptacle and also an E-stop

    Your cabinet looks somewhat different from all of the Hardinge cabinets I’ve seen.

    My cabinet is also mounted on the back. I have only seen a couple of other that had the rear mounted electrical cabinet. The side looks similar and has the stop and green master button. My coolant switch is also mounted on the side panel. The fwd/reverse switch is on the speed control box.

    Do you know if your lathe has been rebuilt. Having that cabinet on back is actually handy. It keeps the bulk of your chips on the top. It also handy to hang the print for the part you are making. The steel wipes clean and won’t scratch or get damaged like plastic shields. The previous owner had a rack made to store his tool holders and other tooling. I got rid of it because living in Colorado i need to wear long sleeves and also jackets while working, and didn’t want to need to reach over the lathe.

    I have seen more than one generation of left side control boxes and they look something like what rpseguin has. Mine is close to his.

    Questions:
    What is your main motor voltage?
    Is that a transformer in the box at the back?

    Yes. It's possible that it has been re-worked by a previous owner.

    Well here's an English HLV-H control box but some is NON standard.

    My machine was produced as a "One off" for the German market and has a THIRD speed range from 40-250 RPM.

    Enjoy

    To answer a couple questions:
    I don’t know whether or not the lathe has been rebuilt.
    The wires do seem fresh and the sheathing is not cracked
    or falling off.

    The Main motor is 440V 1.5 HP
    I don’t know about the Transformer.

    I am wondering why the black cam looking
    thing is only about half as long as others?

    Here’s the Electrical Print.edb85027-909f-4409-9451-489a02972fd4.jpg

    Well I thought it would be viewable but I guess not, I do
    have it on a flash drive in PDF as well.

    Default black cam

    That long cam shaft on mine, is the HI-LO speed lever; it has 6 cams, assuming they are for the 600V. 3 phase motor: 3 contacts for LO, and 3 for HI selection. In LO, it'll go from 125 to 1000rpm, and in HI, 375 to 3000rpm
    The operating lever on top of the shaft bracket, is the same on yours, so I'm assuming yours is also a speed lever control, but yours being a 440v., is where I quit; I'm no electrician.

    From what I have read the contacts on the “black cam” have had problems with the contacts failing. And at some point someone has come up with an alternative wiring design using the Allen Bradley relays that eliminates use of cam assembly contacts.

    Previously I posted a picture of the layout in my cabinet in hopes someone might recognize the wiring and know who might of design wiring layout. At some point I know my lathe was rebuilt, I am just not sure when it was done. Talking with some of the Hardinge rebuilders and also the service tech I had come out and inspect my lathe once I had ran all the power. They all told me the same thing that my electrical cabinet was not wired in known factory diagram. Normally on the last line of the machine tag it will indicate what schematic reference number was used.

    The bed on mine was reground as part of the rebuild. You might measure your bed plate thickness, it should give you an indication if it was rebuilt. The Allen Bradley relays have worked without any issues. They are loud when energized. If you ever figure out who might of design the wiring layout please send me a pm.
