    Default Hitachi seiki hg400 pallet change problem

    Hi all
    I'm new to this posting guys,used the site a few times and it has helped me fix a lot of things.
    The problem i am having at the moment is with the pallet changer,the machine is new to us and it probably is something simple but i'm not seeing it.
    The machine won't pallet change when m60 is called so i've gone into maintenance mode and programmed in mdi the following:-
    M914 (arm low pressure up)
    M903 (pallet unclamp)
    M910 (arm up)
    M912/M913 (arm turn l/r)
    M911 (arm down)
    M902 (pallet clamp)

    When i program the above the arm doesn't lift fully so i tried it without the M914 and it worked
    Also tried it with swapping the M914 and the M903 around and that worked.
    I'm guessing it is something to do with the arm low pressure up,is it a proximity switch,solenoid,pressure switch ?????
    Any help would be appreciated.
    One other thing the APC ready switch doesn't light up when pressed but that could just be he bulb.
    Cheers Scott
