GSM activating upline conveyor while machine is busy | 3 May, 2021

One of our gsm machines has recently started activating the upline conveyor while the machine is working causing boards to double load. Has anyone seen this before or have suggestions where to start before I dig into schematics?

Thanks

does it only do this with one assembly or panel config? i have seen this when the sensor shoots through a hole in the pcb/panel. the machine sees the panel come in, but it either overshoots or moves slightly into the open area. if i remember correctly the GSM PCB sensors have a gain or intensity pot i dont remember all of the reasons we use to have to adjust these (pcb color/finish or glare off a metal surface?) but we did adjust these at times for the same issue.
