Dual Lane Multiple Input with logic gate
As earlier I was searching for an easy solution for 2 inputs machines
I now decided to do the opposite : an "overkill" solution to prevent deadlock.
So we have an SR latch that is activated with the pressure plate just before crossing intersection
When the latch receive the signal from the plate, it's shutting the door for the spark on the horizontal lane.
When hauler came back after feeding the machine it activate the pressure plate again so the counter reaching 2 will reset the SR latch making the doors open again. (The signal entering the non-reset part of the SR will do nothing as it's already in the same state)
Of course everything is reversed with the "NO" signal in the end cause door close when not receiving any signal so having the "NO" signal make them open by default.
The Item filter simply prevent the spark from going into the lane thus shutting all door for no reason if is not carrying any fertilizer.
We also could close door separetly instead of all of them by connecting to each vertical lane the same process counter and SR latch into no signal.
