  • PinSpotting Problem

    82/70C-MP Chassis- Steltronic Scoring. Problem is intermittent. One machine is having a problem of setting a rack of pins. On 2nd ball or a strike cycle, bins loaded with pins but will not drop the pins into spotting cups. The bin switch and lever are good,Chassis and board are good,9P bin switch wiring is good. When you tap or pull TA1 lever pins will drop other times you do the TA2 lever pins will drop. Need help in solving this. Any one out there have any ideas or solutions???

    Does the table go into the long cycle, just no pins?

        Does the shuttle actuator rod spring have enough tension?
        Is the stop lever adjusted properly?
        Is the shuttle cam where it belongs?
        Have the rod ends in the back been greased?
        Is the shuttle height adjusted properly?

          Chuckie; [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] The TB cam is used for interlock purposes in conjunction with the [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] SC switch.

          The [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] TA2 cam is what's responsible for initiating the sweep.

          But, more than likely this is where your problem is since you've narrowed it down to inside the pinsetter by changing chassis.
          Might want to double check for a sweep motor coasting problem as well...if your interlock cams are too far off it will not interlock and allow the sweep to coast in too much

            We had a identical problem a while back, we had to run the table from the chassis when it needed to go in to a spot cycle. The table cams needed "fine tuning", no more problems since.

              Check condition of your SB circuit. SB is responsible for firing the Spot relay at 186 degrees.

              If that looks okay, check the axial capacitor in the wireway which jumps across the bin switch circuit.

                      I'm a bit confused... Knowing almost nothing of the electrical side of the machines.... How does a TA2 switch cause the spot solonoid to fire (not caused, but let the machine know when to fire...), but not work properly? I would have sworn that was a mechanical problem.... *blinks*

                        Adam, I don't have much time but I will sum up.

                        Chuck was vague in respect about what position the sweep was in during his problem. On the 70, the electrical controls the mechanical.

                        The micro switches on the Table and Sweep cams have to be timed properly so that all electrical paths can be opened and closed so that assembly functions can be started and completed.

                        A machine may be timed perfectly, if your lucky, a micro switch that is sticking or starting to fail may talk to you as in Chucks problem. Most times the Normally open or Normally closed side just fail completely.
