shuttling every cycle

8270's, mp chassis, qubica pro



Have a problem that has raised its ugly head. Lane is running a spot cycle without a repsot cycle. Spots pins for 1st ball, then cycles to picks pins up and on the way down to respot dumps another set of pins every time. It was an intermittent thing now a full blown thing. Solinoid is being energized on both cycles. have checked wireway, no shorting is evident. replaced bin switch. kinda scratching my head on this one. if anyone has any ideas, i would welcome them.

Have you tried swapping chassis with a known good one? Does the problem remain? I had that same problem last week. Turned out pin 35 and 36 in C1 were touching each other machine side.

Replace the S relay inside the chassis

And test the machine with all pins in pit so you do not bust a cup or worse an X frame

[BillyJim]

yes, swapped chassis, problem remained.

check the clevis for broken roll pins, make sure the spot hook is not engaging while going through a respot cycle. Check the spot relay for free return, if you pull up on the spot relay and release it it should go back to it's normal resting place, any bindige or slow return in this area will always give you problems.

king replaced all three relays in chassis at different times, problem is still there.

Are you still using respot cell wires or do you have the respot cell wire ground controlled by Qubica?

Funny (or not) but that sounds like it's running a strike cycle every time. Is it an actual strike cycle? This info would actually help.

[BillyJim]

tablejam, no wires. It is running a stike cycle evry time. On 1st ball cycle spots pins, table lowers on respot to pick up pins, picks up pins and on the way down to respot dumps a new set of pins. Cups rotate to spot.

[BillyJim]

solinoid energizes each cycle.

[rivmike]

TJ might have it, sounds like the ground wire is broke. It's not getting told that there is a pin there.

[dothan]

it the camera showing a strike. sounds like its not seeing any pin and tell the table to spot pin not knowing there is pin in the cells.

[Tablejam]

It runs to respot pins then goes through a strike cycle, if table wiring was used prior to Qubica being installed then was removed to have Qubica control the N.C. cell ground either there is a problem with the settings, 6 box or wiring from it to the machine, or the ground between the C2 plug and TAC board has a problem. Its trying to run a respot cycle but then runs a strike cycle because there seems to be no cell wire ground, at least that's what it seems like.

Think simple first. Not matter what, the first 3 posts of every AMF problem posted is always, "Change the chassis"

There's a little spring in the drive eccentric that prevents it from becoming unlatched during respot. Start there and work your way back to the solenoid.

Just because AMF pinspotters are electro-mechanical, doesn't mean the problem is always on the electronic half of the machine.

Solinoid is being energized on both cycles.

Ignore the eccentric roll pin/spring suggestions,

yes, swapped chassis, problem remained.

The problem must lie in the machine/scoring wiring interface.

How does your Qubica interface with your chassis? I assume this is happening on only one machine. When your scoring reads a strike, does it go through the short strike cycle? Or the long strike cycle like your describing with your problem machine?

I would trace the wires that come out of your Qubica into your machine, and maybe check a working lane next to it and see if any wires dont match up, or if your find something goofy in there.

I have SS chassis here, and the Qubica interfaces by using the old long strike cycle, so its made to jump the cell grounding in the trunking, so that when there is a strike it will do the long strike cycle. If there was a short near this circuit i would get the same sort of results your describing.

However if your scoring goes through an XLMP box to your chassis, it maybe worth swapping the XLMP with the pair next to it to see if its that sending the goofy signal to your machine.
Does the X show on the masking unit when it does this crash cycle?

Interesting question, when you turn your machine on without the scoring and cycle it from the back box, does it still crash cycle? If not i would move the scoring components one by one to lanes near by and see where/when the fault moves with which piece.

Yes yes, I agree!
