intermintent no cycle

[J-man]

the topic says it all, i have two lanes that on the strike cycle will not give bowlers a set of pins on the deck until you force it to cycle. i have indeed ripped out the 5 boards (may i mention how theraputic using them for target practice is!) and replced them with m-tek boards (no pin) and still a random problem with no strike cycle. the masking unit does show that it is getting sgnal from fingers on table that all pins fell.

sorry for the rookie question, but what do expect from a rookie

thanx in advance everyone, Jeremy

hope your christmas rocked and Happy New Years to everyone.

Re: intermintent no cycle

UMMMMMMM ok
When you say (FORCED)to cycle ?? What do you mean??
On strike cycle the sweep comes down & tables feels for pins, Sweep runs thru then waits for table to shuttle pins ??
Do you have to hit the stepper switch then cycle it again ?

First check your micro switch in the #9 bin.
Then check your O.S switch. More info would be helpfull.

Re: intermintent no cycle

Little more info please.

Does your scoring interface with the machine operation? For example do you have a short strike cycle… whereas the table does not feel for pins when a strike is thrown?

If the scoring does not interface with the machine operation and your table always comes down to feel for pins, then I would suspect that one ore more of your RSC wires is grounding. This could be due to the tiny adjusting screw that is on each RSC. Check all of these screws and make sure they are adjusted properly and that you don’t have excess slop in the RSC itself.

Re: intermintent no cycle

by forcing cycle i mean the switch on the ball return or using pc.

table comes down, feels for pins, indicates strike on mask, table goes back up, sweep runs clearing deck. now heres where the prob is, instead of sweep stopping in guard position & table setting pins, the sweep returns to its start position.

the part that baffles me is that it does it about every other or third strike thrown.

Re: intermintent no cycle

Ok a little clearer. Check your wires at the cushion switch and make sure they are not grounding or touching each other.

Re: intermintent no cycle

Just a suggestion or two:
problem I've experienced, there is a spring behind the catch to release the eccentric for a long stroke, this spring has sprung on me in the past and will not allow the table to make a long stoke. So I would ask? are the pins in the cups or still in the bins? and is the spring sprung???
Also how does your selonoid linkage look?? especially if the sweep is returning to 0.

<font size="2" face="Verdana, Helvetica, sans-serif">pins are not in cups, the shuttle does load pins, as far as the spring goes it in is tact, i will check selonoid linkage. thanx

Re: intermintent no cycle

Is the seloniod firing intermittenly??
Sp relay good or going bad?
or linkage jambing?
Just a few more for ya.

Keep us posted.

Re: intermintent no cycle

I see where simbowling2002 is going, but we need a little more info that is not clear in your post.

Does the sweep stop at second guard position waiting for a table that doesn’t spot?
Does the sweep not stop and the table does not spot?
Does the sweep just keep running past second guard to zero without stopping?
After the table feels for pins on the first ball does it go down a second time when its supposed to spot but it is going down to feel again?

Step by step of what is going on would really help us.

Example:
Sweep drops first guard
Table feels for pins and sweep runs through and stops at second guard
Table comes down but does not spot pins and sweep goes to zero

Re: intermintent no cycle

Sounds to me like the table is not runing the secont time at all.

Sweep drops. Table feels....Sweep runs....and keeps right on going to zero, is that correct??

I would check the cam switches first. Sounds like sweep is (sometimes) over running on second guard and just never stops.

Do you have, by any chance, a spider relay installed?? Some after market device to give an automatic reverse on sweep reverse, and have you seen it happen from front.

Long Shot Theory (grasping as straws, 1st instinct would be cam swithces) false off spot, and it is actulay a foul on the mask, not a strike?? (probably would happen on cycles other than strikes, so this probably isnt the problem)

Try swaping the chassis with a lane that is not having problems, see if it follows.

Re: intermintent no cycle

J-man take a working chassis off another machine &amp; trade this chassis with that 0ne. See if the problem moves. We need to start eliminating things. Just because you put m-tech boards in dont mean anything as they went into the same chassis. That should be your first move. By checking off one thing at a time. Sooner or later you will find the problem. Start with the easiest first, then work from there.

Backup Ta1?

Rotate The Cam Back Or Away From You

Re: intermintent no cycle

If problem stays. Then I'd follow Jim's advice &amp; check your cam switches. Check the cam's &amp; micro switches on Both sweep &amp; table.

Re: intermintent no cycle

Are the AMP plugs on the machine side in good shape? C2a?

Re: intermintent no cycle

sounds to me like machine is going thro a normal first ball cycle.could be a cell is grounding and machine still thinks a pin is there.also offspot switch may be out of adjustment. also cams SB TA2.
the fact that it puts ten pins down after hitting 10th.frame switch indicates machine is getting a different signal than scoring.
just a few ideas.
good luck.
