The magnets are doubled up because of the gap/clearance needed for the switch and magnet. Single-stack them and you will wipe out the switches on the rail clips. If you have magnets for 61u, 61n and 30 you don't have a V3F25 drive. You have either a KDL16 or a V3F16L, depending on the age of the unit and if it has been upgraded or not.
When you're parked in the middle of the 30 magnet, move the 61u switch up until the led on the CCBN goes off, then move it down so it comes back on. Move the 61n switch down until it's led goes off then move it up until it comes on. It's been a few years since I adjusted these critters, doing my last years in the service department, I think the starting distance between 61u and 61n is something like 5.25 inches. I'll look through my literature and see if I can find it. You will need to run another shaft learn when the switches or magnets have been moved.
