I was having a problem with the tool changer not aligning up correctly with the Z axis. I tried moving the "cross" looking plate on top of the position switches on the back this would "clock" the carosel correctly. I guess I moved it too far and now the ATC alarm light will not go off. The only way I can get it to go off is by moving the "cross" so that the lights on the position switches go off. I can them move the carosel manually but when the position lights are on the ATC alarm light comes on and will not allow me to MO6 and call a tool. Please help as this was all functioning perfectly until I moved the "cross" looking piece in the back.
