      Replace the micro switches.
      Check the springs on the fingers.

          I was just translating your short post into a understandable one. You've been gone for so long. Going to take awhile to get the kinks worked out. :p :p :p :p :p

            Re: interlock

            when you say you checkd cams, are you refering to the switch adjustments? That would be my 1st thought. If the gaps between the fingers and the cams are not set correctly, the cams will send info to the chassis at inproper time, ans interlock will occour. describe the interlock...what direction is the table and sweep going in, and what cycle does it happen? this will narrow it down.

              Check micro switches, we had one short out because of oil getting into the switch, it was very had to find at first, but got the problem fixed. no more interlocks....

                May not be electrical.

                The interlock could be caused by the sweep catching on a loose / broken edge strip of the pin deck. The sweep will get stuck on the sticking out plastic strip and stop moving, thus the machine will go into an interlock.
                Just another thing to look for.

                  HI JIM , I WILL TRY TO EXPLAIN IT BETTER FOR YOU THE MACHINE GOES THREW FIRST BALL CYCLE ,THE SWEEP HITS THE PINDECK AND WAITS FOR TABLE RUN BUT WHEN THE TABLE IS HALF WAY DOWN THE SWEEP KICKS IN AND TRIES TO CLEAR AWAY DEADWOOD THUS CAUSING A INTERLOCK .WHEN ITS IN INTERLOCK IT WORKS IT WAY OUT OF INTERLOCK BY ITSELF AND SWEEP GOES UP TOO ITS NORMAL POSITION SO THAT YOU CAN BOWL .I HOPE I EXPLAINED IT BETTER.

                    Re: interlock

                    You say the sweep starts when the table is half way down - i.e. the table starts, then after going half way down to feel for pins, the sweep starts and thus interlocks.

                    This sounds like the TA2 cam is in completely the wrong position.

                    However, if the sweep and table actually start at the same time (which may look almost the same as the first case), then the likely culprit is the SC cam.

                    If SC activates when the sweep reaches 66, then after the time delay, both sweep and table will run (and thus interlock).

                    At least two things can cause this: maladjusted SC cam or lever; or, slack sweep motor that overruns 66 by enough to activate SC. Note that there isn't much rotation between SB and SC (only 5% of the shaft's rotation). So a slightly slack sweep could easily do this, sometimes intermittently (which is a pain to try to 'adjust around').

                    Hope that helps,
                    Andrew Kennedy.

                      Re: interlock

                      Oh, I forgot - the fact that it "works its way out of interlock by itself".

                      That seems only possible if SC or TB are not working. It would also potentially do a bit of damage.

                      I'm not sure if this is also the cause of the interlock (SC is a common factor), but you should check this. Try cycling the machine and then hold SC and TB out at the same time - the motors should not run.

                      Regards,
                      Andrew.

                        I had this problem in Vermont. Check the wireways EXTREAMLY closly. Mine was a wire hair (from my whire grinder wheel on the bench) that had worked its way down into the wireway and was shorting out 2 terminals that happened to be part of the table cam switch cluster. It was such a small wire, that it only did it accosionaly, and was VERY hard to spot. Accidently cought a reflection when I took the flashlight through it for the 3rd time.

                          Re: interlock

                          Sounds Like The cam position is out on the table drive shaft or an intermitant fault with ta2 micro
                          chek the location of the table cams with the lane next door when the table is @ 355 or the up postion the clamp stud on the table cams should be roughly parralell to the pin deck
                          hope this helps
