  • Ball Detect Setting Off Both Lanes

    Here's another prob
    i'm having. I have bowltronics ball detects to cycle the machine. When someone throws a ball on 15, lane 16 cycles also. I've switched out the detects and same thing happends. Any ideas. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

    Switch the terminals in the AMC box.

    15 is cycling by the SS and 16 is cycling by the trigger. Make sure the wires are not switched or the detector head is not installed backward.

      Ok. checked the amc box and its ok. The wires are in the right places and the detect sets off the right lanes. Now and then 16 still is getting triggered by 15. I switched the boards and the detect out and still once and a while, 16 still cycles..

        How solid is the ball detector mounted?

          It's mounted right behind the down sweep on the wood frame. It has the rubber mounts to cushion it but it barely moves.

            Is/are the reflectors under the down sweep or in-between pairs? I ask because a common problem is the collecter from one sensor sometimes locks on to the emiter from another.

              The reflectors are in-between the pairs. I just can't figure it out.

                it could be a reflection from the pit light as the ball passes it shadows across the other lane.ensure the reflectors are positioned only to reflect to the one lane and not allowing it across to the next.there was a case a few years ago where a signal was coming from another pair of lanes e.g.5/6 a ball on 5 would set off say 7/8 we had to shield the reflector on that one.the reflector was not looking directly at the sensor and was getting confused,it was angled upwards and although still cycling the correct lane when a ball passed , it picked up reflections from elsewhere.

                  I was having the same exact problems with the AMF triggering. One lane would set off the other and just intermitant triggering. I fought a pair of lanes for many of days and finally just gave up. Then I would have another pair would just cycle on its own. I even installed a piece of cardboard around detector head to prevent cross contamination. Didnt work.


                  What I did notice from day one is that with the triggering mounted under downsweeps the sweep would break the beam fron 0-66 degrees and 270-0 degrees. And by golly (did I just say by golly?) I think thats the problem.


                  I reinstalled the triggering on the downsweep covers, which is about 26" away. Problems are all gone. In fact after I repositioned the triggering I forgot about the bumpers getting in the way. I had a pair that had almost no return and didnt fail. I had to raise the reflectors about 3/8" and adjusted the heads all the way up. This is only where I have bumpers.


                  I only have triggering on lanes 1-12 for now and I repositioned all of the in about 2 hours.


                  I know that the instructions say to mount them under the downsweeps but it just wasnt working. You will also have to adjust them for a slight delay since the are no longer mounted behind sweeps.

                    I have found the best place to install the ball triggers is on the front of the downsweep enclosure and the reflector fitted on the mask leg.this does seem to help eliminate other light sources and other reflective images. Remember to raise them high enough to avoid bumpers triggering them.
                    good luck.
