breaking in new DZ-2500s

You must be extremely attentive to detail when setting up the DZ-2500s. They work well when perfectly aligned and have no added torque applied to the mounting screws. The way I mounted mine was to set them down on there mount with double stick tape and fiddle with them until they worked right. Once they were working correctly I would then drill holes for mounting them and very carefully screw them down until the screw just contacted the machine. Any further and they wouldn't work reliably. Attention to detail is extremely important. My guess is they're over tightened or not centered. I have 14 of them running at present and they all work fine and have been for 2 years.

Thanks for the reply. These came pre-mounted when I bought the switches so I did not do the install, although I have a couple that I will be installing. You would think that Ross would test them to make sure that they work properly! Sounds like a good idea to loosen them up and see what happens.

It worked for me. My opinion is they need a little more support than Ross provides. I made a mounting block that is exactly the right height with the double stick tape to support the machine without raising it. I glued these down and then proceeded to mount the machines. Most of my switches are Atlas with a couple of Ross. Ross could align them but after a trip in the plane / truck the alignment would be gone.

It worked. I loosened them and the switches throw in both directions. Some of them run on linger in one direction than the other but I am hoping that will sort itself out when I run them awhile.

If they don't throw equally in both directions try moving them at an angle one way or the other to center the throw and then tighten. Usually the throw isn't centered when that happens.
