reversing conveyors

Im trying to get my reversing conveyor to work and getting the error about stradling..not sure how to fix it? Attaching a simple example of what i need to do. Once I get 3 pallets on the side reject conveyor, i wait 2 mins then feed them back one at a time. The side reject conveyor is 3 separate sections and they manually turn one on at a time. I had it working with one section but when I learned they needed 3 to account for extra time I cannot get it to work. Reverse_Example_1.fsm

I'm also noticing the transfer time is not being accounted for coming out..it works going in, but not out.

Hello @Amy M3

I received help from @Brenton King with this solution. You mentioned that you needed there to be three separate sections which we can still work on to try and achieve. Could you look over the logic that decides to release the rest of the flow items once the reverse conveyor logic had been executed? That logic does not seem to be working in the model. reverse-example-1FS.fsm

Hi Jeanette, not sure what's happening now..but it's reversing in my real model I posted privately I tagged you in. I've given up on the sections and just added a timer to account for the total time to empty. In reality, they only reverse one at a time so it takes a little longer. I couldn't get that to work so I have it as one section and just account for the total time to empty now in process flow. Supposed to have this done this week so I can just go with my work around vs trying to get 3 separate conveyors.
