Superstar chassis from AMF problem

[NCWINGNUT]

Do any of you have the Superstar chassis from AMF?
We have several ultra 98 and superstar chassis's and we are haveing trouble with the 9 pin switch, seems like more often when the person strikes. When the 9 pin switch is activated, the machine will shuttle, then everything freezes, you can go and hit the switch and will start back up and run fine. Could this be a problem with the cams and/or switches being out of adjustment? Any suggestions? I have replaced the switch thinking that it might be going bad, with no luck.

Re: Superstar chassis from AMF problem

I dunno about the type of chassis you have. We have SS's and the last time we had this problem the spotting relay was the culprit and we put new stacons on the bin switch just for good measure and haven't had a peep from that machine since. If they have a spotting relay in them I'd check that, if not ignore the post [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Re: Superstar chassis from AMF problem

We have been using Superstars-Ultra 98 plus for almost 5 years now without any close to the problem you describe.

Is it happening on all lanes or certain lanes?

<font size="2" face="Verdana, Helvetica, sans-serif">Check to make sure that you have an axial capacitor (100uF @ 50VDC) bridged across terminals TS32 &amp; TS 34 in your wireway. This is your bin switch circuit. Most factory MP pinsetters were shipped with ths guy as the chassis sometimes has a hard time reading the voltage. We had factory MP 9802 chassis before sitching out to the Ultra 98 Plus (Superstar).

When bridging the cap across the terminals, place the positive end on TS-34.

Re: Superstar chassis from AMF problem

On some machines the counter at the frontdesk is wired parallel on the spotting relay, if there is a short in your counter(or the diode/capicitor across the counter)you might get the problem you describe.
Good Luck

Re: Superstar chassis from AMF problem

We are only having this problem on certain lanes, 3 of them to be exact and this happens with both superstar and ultra 98 chassis.

Kat is the man....take his advice.

Re: Superstar chassis from AMF problem

Kat is correct...without that capacitor, the 9 pin leaves as the shuttle moves forward, the switch resumes its empty position and the chassis thinks there is no pin in the 9 pin and waits. The capacitor maintains the circuit long enough for the table to get going and get by that point where the chassis would wait. Thats why going up to it and hitting the bin switch will resume the operation. Hope that isn't too vague...

<font size="2" face="Verdana, Helvetica, sans-serif">I had limited experience with the ultra 98.... The one thing I know, I wans't impressed....We had 10 ultra 98's manufactured by CTI. I had continous problems with 3 of them...sent each back at least 3 times.....over a 3 year period. however, CTI has been bought out by ZOT, and they assure me the problems I had will be resolved in there "New and Improved" version....the funny part is that I no longer work for that center, and dont have to worry about it anymore. (zot was never able to resolve the problems in 2 of the units, and agreed to excange them for 1 new one)

<font size="2" face="Verdana, Helvetica, sans-serif">In the SS chassis the SP relay kept the BS circuit closed. That's why the capacitor wasn't needed. Why they changed it is one of the great mysteries of the universe.
