Sweep up, Fingers closed

[kevin]

Hi All,

I gotta problem here.

We will get called to the machine to spot pins
Sweep will be at zero position and the fingers will be closed, No pins on deck. This is a 8290XL, Qubica scoring.
I will have to check what ball the machine is in
when this happens.

Anyone ever have the above problem?

Does Qubica have any control over the functioning of the offspot cycle threw there spec codes ( MCU )? I know AMF has there own Spec codes for different functions for amf scoring, But is there different Spec codes when using Qubica scoring? I think this could be part of the above problem.

I also have some machines that if there is a offspot pin the Table will come down on it as usual and the sweep will reverse and go back to zero on its own [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img] . Only problem with that is I still got the dead wood on the pin deck .

Re: Sweep up, Fingers closed

Sounds like there is a strike and it is seeing a pin that is non existant.

Check and recalibrate camera and check for shiny spots and light in the pit area.

Re: Sweep up, Fingers closed

Maybe someone before you did build an offspot system in the machine?
I have such a system and sometimes with a single pin offspot the pin will fall over(after sweep reversed and table back at 355 with the fingers closed)and roll in the pit, machine should be on second ball then.
If you want to check if you have such a system push the offspot switch with the machine at zero, if the sweep wiil run in reverse you have it.
Maybe the 8290XL does have that feature already build in???
Wrong finger/badman cam adjusment(the pubic hair adjustment [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] )is also possible.
And King gave a good one too.
Good luck

Re: Sweep up, Fingers closed

or possibly table stopping past 355, so spotting solenoid cant engage, causing table to go into one rev of respot cycle, instead of spotting cycle

or somethin wrong in the solenoid springy deal <<-- technical term

Re: Sweep up, Fingers closed

My lane #6 was doing this all last season. I agree with Coors because my machine was in 1st ball. The bowlers would have already hit the 10th frame switch and all I would have to do is open the fingers. I think the table was coasting every once in a while. That chassis is on a different lane now and I can't remember if I replaced any contacts or not, I think I did. I do remember that if I watched it, it would work fine. If I go away, it happens 10 mins later, might not happen for an hour. Go figure!! I now have Qubica scoring with expanders and haven't seen this on any lanes so far this season. Make sure you check if it's in ball 1 or 2 and if you have a gripper protection switch all you'll probable have to do is open the fingers if it's coasting once in a while. You can recreate this situation by either cranking the table past 355 by hand, or pull out TA1 briefly to get the while roller moved up to where that lever can't catch it. When it goes to spot pins, table will do short stroke, close fingers and machine will be in ball #1. I'd say check lower contacts, C1 and caps. Maybe switch chassis first to see if the problem follows??

Re: Sweep up, Fingers closed

Geeeezzz, I can tell I'm tired, I missed the part about them being 90XL's. Those are all solid state motors and chassis. All probability it's not a coasting sweep. Mine never coasted, but they were new and I only worked on them for two years. Might want to give Carl @ AMF a call to see what might cause one of those to coast. A couple of other things come to mind now that I see they're XL's. Maybe a pinchaser tried to adjust the cams or cam switch levers for some reason, or something came loose, leaving the table a bit past 355 when it stops and not catching the white roller and spot lever soon enough once in a while???? Or (God forbid) something shifted with the table drive shaft? The shaft itself, or the big bearing may have a problem?? (Hope not!!) Or like coors said, maybe something with the solenoid.

82-90XL's do have an auto offspot reverse sweep feature built in but you have to activate it with the MCU first. You pick the lane range then turn it on. Been too long for me to remember the code number, there should be an MCU code book around there somewhere. That feature is designed for open play, but should be turned off for league and tournaments because deadwood has to be removed according to rules. I doubt there are different codes for Qubica but to make sure, you should call them 1-800-495-2400. Check to see what ball it's in then we can narrow it down.

I sure miss my XL's [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img] Where are you located kevin?

Re: Sweep up, Fingers closed

I don't know if the 90's have this part on them, but the respot finger spring (part#070000807) can get hung up on the pivot weld(070001804). The finger link won't close the cells when the table comes down to pick up the pins and they get swept off. Then the table comes down the 2nd time and closes the cells. When table returns to 0 (355?), the cells are closed with the sweep up. It has happened to me a few times and is usually caused by a worn spot on the finger link pin(070002592) or the pivot weld being slightly bent. Hope this isn't too confusing.

The MCU code to disable auto offspot release is Spec 26. On our system Qubica does not interface with the MCU.

Re: Sweep up, Fingers closed

Hi everyone,

Thanks for all your replies. the machine has not done it again since I adjusted the sb &amp; sc cam to aline with the cam levers. The roller part of the levers was not riding the cams properly it was riding more on the edge of the lever.

If I have any more problems I will find out what ball it is in and get back with you all [img]/content/btubb/images/%%GRAEMLIN_URL%%/cool.gif[/img]

Thanks again,

Kevin

Re: Sweep up, Fingers closed

just for reference....spec 40 will reset your chassis from the front...I use this feature if I turn a machine onto manual cycle to spot pins and forget to turn it off manual mode...the league gets done and the pindeck light is still on....Just hit spec 40, and it resets the chassis and turns off the pindeck lights....GOLDEN!

Re: Sweep up, Fingers closed

What uses do you get from these?

Spec 21 Read chassis software version?
Spec 999 Read MCU software version? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

Re: Sweep up, Fingers closed

Newer versions of the chassis have features that older chassis don't. for example, on newer chassis an led blinks when the machine is on second ball. The older ones don't have it. If you have a list of features and the software versions that support them, you can determine whether you can use a particular feature. We have one chassis that supports auto backend shutoff (the default). If we wanted to turn it off, we would be out of luck because our MCU software version doesn't support it.
