  • continous table

    Got a call from another center. They said sweep was hit then machine went into a continous table. Chassis has been changed and this only happens on 1st ball. Sweep down then cont table. I was thinking TA2, any ideas?
    If it cant be fixed with a hammer, use a bowling pin.

    Doesn't the SB start the table timing at 1st guard?

      If the table is running then the time delay has ran and expired. If it was TA2 then the sweep should also be left at 270 at the end of a cycle. Strange that a sweep hit would cause this. What about a different chassis board?

        TA1

        A Brief Treatise on Cam Switches:


        The table and sweep cam switches allow the chassis to monitor the locations of the table and sweep for proper cycling of the pinspotter.


        Table cam switches are located on the left next to the table motor, sweep switches are located on the right next to the sweep motor.

        The table cam switches from left to right are:



        TA1: Determines the home position of the table.



        TA1 out of adjustment too far in:

        1. Table stops before zero position.

        TA1 out of adjustment too far out:

        1. Table runs continuously.




        TA2: Initiats the sweep run-thru.



        TA2 out of adjustment too far in:

        1. 1st ball-sweep down to guard position, table continues to run.

        TA2 out of adjustment too far out:

        1. 1st ball-sweep down to guard position, time delay, sweep runs, clears pins and stops at guard. Table does not come down.




        TB: Lets chassis know that table is within range of being hit by sweep

        TB out of adjustment:

        1. First ball, sweep starts towards pit, table starts up with pins in gripper, both stop, neither will run with SA1 or TA1.





        Sweep switches from left to right are:



        SAetermines the 2nd guard and home position of the sweep.

        SA out of adjustment:

        1. Sweep runs up, down and starts to clear deck a second time as the table spots pins. Table and sweep stop because of interlock.

        SA out of adjustment too far out:

        1. Continuous sweep run.



        SBetermines the 1st guard position of the sweep.

        SB out of adjustment too far in:

        1. After cycle starts, sweep runs continuously.

        2. 1st ball - after time delay the table comes down, sweep starts and stops under the table as it comes down to respot pins, table stops.



        SC: Lets the chassis know the sweep is in range of being hit by the table.

        SC out of adjustment too far out:

        1. 1st ball - sweep down, table down about halfway and stops. Table will not move by lifting TA or SA.

          That is correct, but that seems to be fine. What they said is table would start but then sweep would stay at guard and table would keep running. I will be there tomorrow morning but was hoping to get them up today since they are 12 lanes and this is a holiday weekend. Im sure when I go there the whole story is going to be wrong, and it will take 2 min to fix problem.

            Could be TA2 or in the chassis or board in chassis. I would swap chassis with another lane first. Hopefully eliminate the machine from the equation.

              LMAO!!!!! It took me a while, but I finally figured out that it was easier for them to dial my number than it was to go look at the bloody machine.

                QUIZ TIME !!!

                I went into bowl today and found problem. Sweep down and then continuous table. TA2 was the problem, but why? Hint..not electrical.

                  Ok so not electrical well then either the adjusting screw was worn, adjusted wrong, missing, the switch was broken or loose or sticky, the lever had roller issues, or the cam was bent or something or maybe something like a nut, screw, or washer fell in there.

                      TA2 is lifted off the switch to run the sweep, the spring holds it on the switch until the cam lifts it. If the spring broke the lever would never push in the switch which would cause the sweep to never stop at guard. It would be the same thing as having the adjusting screw turned out so far it could not push in the switch.

                        This may be the best quiz ever. I will reveal the answer on Tuesday unless someone gets it right. Good luck to all!!

                            There was a small piece of junk holding the TA2 away from the switch.

                              Is 2nd ball cycle working?
                              OR
                              the sweep is just staying in guard and the table runs continuously?
