  • not a chassis problem

    first ball cycle

    machines cycles - sweep drops to 66 - then as you think the table is about to start the sweep starts with it, causing an interlock.

    this can happen 10 shots in a row, or go normal for 10 shots, but it is happening regularly.

    please help

    Are you sure it's not in the chassis? Also, I would check the table switches. If one is bad, it could make the sweep start prematurely. Probably wouldn't hurt to check the sweep micros either. If it happens that often, it probably won't be that hard to narrow it down.

      Check the gap and/or microswitch itself on the TA2 cam as this is responsible for running the sweep in conjunction with the table. It causes the sweep to run when the table is high enough to clear deadwood and return home when the table is high enough.

        As Kat mentioned, the TA-2 sends the signal to the chassis that tells the sweep when to run from 66 degrees. The TA-2 lever would have to be touching the cam or extremely close to create the problem you describe.

        If your TA-2 is fairly close to proper adjustment then it is possible that you have a defective switch or a very weak spring pulling on the lever (which could also be sticky). Sometimes a switch could get sticky or will get a carbon build up inside that will create a carbon trail that will break and reform because of vibration and arcing.

        I would definitely concentrate on the TA-2 with a remote possibility of the SB switch or a coasting sweep motor.

          It sounds like sc is being activated at 1st guard.Make sure your sweep cams are adjusted properly.

            Craig: just run through and re-time all your switches.

            Like the guys said, focus on TA2 as this is the switch that initiates sweep run through.
