Sweep stays at 270 guard position

[Doug]

When the first ball is thrown the sweep comes down to guard 270 position then stops as its supposed to, then the table picks up the pins and goes to top position and stops but the sweep never runs to clear the pin deck, I can make the sweep run by manually activating the SA switch. The machine runs through a 2nd ball cycle just fine. I think its a micro switch but not sure which one could be the culprit.

Any Help as always is Greatly Appreciated.

Thanks!! Doug

Re: Sweep stays at 270 guard position

Check your offspot microswitch first, that would be the obvious culprit. If not that I believe it's TA-2 that controls the sweep running after guard (not sure here, please correct me if I'm wrong guys). Check that offspot switch and the adjustment for it and also check the 2 small bearings in the table drive clevis (on the piece thats on the table drive unit itself, I think they call it the yoke) cuz that will also cause the problem you describe though usually only intermittently. Good luck! P.S. 2nd guard is 270. I knew what ya meant though [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

See if your 2nd ball light toggles when the table stops with the pins in the air.If it does you are getting an offspot signal.

Remenber ball light toggles over with signal from(ta2) an (SA) switches Or (ta2) and (offspot) switch.

I think thats right,someone correct in if not....thanks

LOL!
How did HE get to use Doug as a member name? I had to choose another one because it said "already in use" or something like that! :p

Oh, well! Glad to have another "Doug" aboard!

<font size="2" face="Verdana, Helvetica, sans-serif">Well, Doug (ModelTech). He registered in June 1999 so he is probably the person who had the name when you tried to get it. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img] As for Doug's problem, it's pretty much been thoroughly evaluated by the other guys so I don't have much else to add.

Hi Guys.
I agree with Rep and Masternut about false offspot if machine jumps to second ball, but don't overlook bad TA-2 cam switch.

Just disconnect the wires on the off spot switch. If it stops....

Re: Sweep stays at 270 guard position

Thanks everyone!!

Unplugging the off spot switch took care of the problem..

Thanks!!! Doug

Re: Sweep stays at 270 guard position

Check those bearings out that I mentioned earlier, many of the false offspots I got were due to those bearings going bad. I suppose the switch itself of the gap for the OS switch could do it too
