Our IPII just developed yet another issue. The PCB goes in the conveyor and when in the loader, the lifter goes up and after a few seconds I get a lifter cycle alarm error. I checked the in/out screen and when I make the lifter go up, the sensor does not change from "X" to "0". The sensor for when it is down does change. We traced the wires from the schematic to one of the VME boards. Is this a VME board malfunction or a sensor one? There is a sensor on each of the pneumatic actuators for the lifter. Two are on when the lifter is down but I don't see any on when the lifter is up (this is when the error occurs). Any help is appreciated!!
