  • Sweep problems

    Hi all,

    Im new to this.
    Iv been left in charge while the head tech's in Aussie...nice for some huh...right...problem...i have a lane that when the sweep drops down to the pin deck thats where it stays and doesnt continue the cycle, have to use the sweep contact to return it.
    Things i have looked at
    - Table height (Not over running)
    - Changed sweep micro switches
    - Tryed diff chassis
    - Checked wireing in trunking, found 1 wire loose but didnt fix the problem.

    Help please??
    Thanx

    Does the table start running at all?
    Failed safety course.Question #1:In case of fire what steps do you take? Apparently 'Friggin long ones!" is the wrong answer.

      No, the machine just freezes and nothing goes, also forgot to mention that the 2 yellow relays on the board are ticking.

          I posted this on the other thread.

          Something is preventing the time delay to run out.

          If this happens on first ball only could be the GP switch on the table is bad, out of adjustment, or has wiring issues between it and the front wireway

          If on both first and second ball all you get is the sweep dropping to guard and that's it then it could be the OS switch is bad, out of adjustment, or has wiring issues between it and the chassis.

          To test if its the GP (gripper protection switch located on the table between the 8 and 9 respot cells if you have it) make sure the cells are open fully. If they are not the switch will prevent the table from running on first ball and damaging the cell fingers. A quick test would be to connect both wires from the switch together without them touching anything, if it then works then its a switch or cell adjustment issue. If not its wiring, could be in the table cable plug or after that.

          If its not that switch it could be the OS switch, especially if it happens on any cycle. To test remove both wires and tape them individually, if it then works then its a switch adjustment or switch issue. If not the wiring could be damaged and grounding somewhere between there and the chassis.

          That's all I got right now.

            Glad I read this post. It just reminded me that I have a broken OS wire on a lane. While I'm at it I will check them all.
            If it cant be fixed with a hammer, use a bowling pin.

                ok found new problem on same lane....dont no if its linked to my current problem but when using the sweep contact to bring the sweep back up again, on the way up the contact clicks on, off, on, off, on, off....on the way up....would this be the cause of my main problem??

                  Check your sweep reverse switch, Sweep run power goes through it.

                      Is your table still not running when sweep is at 1st gaurd? In the wire way to the right of the power plug where all the cell wires hook up, find the 2 yellow wires for the gripper protect sw.(bottom right) pull off the two thin ones and put both thick ones on the same u post.( not sure left or right without looking at it) I made a 2 inch. jumper to go where the two thin wires go. Either way will work.

                        Hey thanks but we dont use GP Switches, they have been removed from all lanes

                          Are they jumpered in the wireway or where the switch was ? Is the table running 1st or 2nd ball ?

                            the problem is on the 1st ball cycle, not sure if there jumped or not but all other lanes dont have the GP switchs and they run fine but will take a look, thanks mate

                              Alright this is what we got so far....

                              Only on first ball, sweep runs to guard and nothing else happens also sometimes sweep contactor chatters with sweep on the way up....no GP switch.

                              Both of these problems can be caused or related to the OS switch or bad wiring. If the wiring is intermittently grounding quickly when the sweep is going up the contactor will chatter. If this same circuit is closed or grounding when the cycle starts the sweep will run to first guard and that's it. Flaky switch or bad wiring.

                              I imagine that this sometimes also happens on second ball.
