    Interlocked guards needed, Interact 1 mk2

    Hi all.

    I have to fit interlocked guards to my Bridgeport interact 1 mk 2 with a heidenhiem TNC 2500 control.

    Does anyone know if the control supports an interlock switch, and if so, is the switch and wiring readily available and simple enough to fit?

    Any help is appreciated.

    HSE is awaiting conformation of fitted guards

    John.

    That would work, but for high production runs it would be a pain,

    Cancel alarm,
    turn control on
    and then press cycle start,
    aswell as the extra operation of opening and closing the door,

    I was hoping for something a bit more egonomic, shut door press cycle start.

    This control is fitted to many different machines. Those with a enclosure do have a door interlock that this control supports. The more common question is how to turn it off.
    So you need the parameter and a set of wiring schematics from a VMC to get the input/output locations. The input for the fact that the door is closed, that it has locked, and the output to lock the door.
    Is this machine not "grandfathered" and exempt from this requirement? This seems a bit odd.

    probably a plc function that may not be in the machine

    a simple way to do it would be to engage the lock when the spindle is enabled and put the switch in the spindle enable circuit. Risk of blowing things up if you monkey the door open since it would not disable the drives.

    EMO string is the best bet, but a pain
