    Chuck open signal needs to be reversed

    I'm trying to interface an old 1993 LNS Quickload
    with a 2008 Puma 240B with Fanuc 21iT control.

    All connected, but the control sends out "chuck open"
    signal when it is closed.

    Is there a way to reverse the output?
    On when open, off when closed.

    Thanks

    I believe you can change it on the LNS side.

    Ya, thought there was a setting in the LNS for pullback style or dead length style clamping.

    Thanks, I'll play with the buttons to see if I can figure out to find the parameter.
    If not, I'll wait until Wednesday when LNS gets back from holiday.

    Figured it out.
    Wired in a relay to reverse the signal.

    All is good!

    Thanks
