Gripper SW on 90's

[Kingram]

If you have 90's with the aluminum table and gripper switch don't get rid of them yet. Think we have a use for them. Am at home now but am going to try this tomorrow.
If for some reason the pins left on first ball were to hang up in the respot cells (which is often with a screwed up cell or bent stud or whatever) a league bowler would call for pins hanging to be respotted. If you have a co(?)mic bowler they just cycle the machine and watch and laugh as the table spots on the pins left standing. Not a pretty picture or sound. My suggestion would be to wire the bin switch wire through the gripper switch to the BS.
If the monkey bowler cycles the machine all you get is a sweep down and then you know that there is a respot problem instead of wondering what happened. This would save a lot of cups, respot cell parts and links. Some of you guys that have more experience on the 70's and 90's kick this around and give me a reason this fix will or won't work.
Thanks,
Ken

Re: Gripper SW on 90's

Ken...just thinking outloud, but what would happen after a strike is bowled ? Fingers would be closed and thus the bin switch would think there is no 9 pin. What I did was to wire the 10th frame switch through the G.P. switch, so if pins were hanging, the bowlers would not be able to even cycle the machine. What do you think ?

Re: Gripper SW on 90's

Alan, That is a great idea with the 10th frame sw. On our 90's the table doesn't feel for pins on a strike, just sweeps dead wood then a full set of pins. Thanks for your input.

Didn't think about a full set of pins hanging. Wonder if the sweep would clear them?

I have 70's, as you can now tell.

Re: Gripper SW on 90's

Ken...your idea should work just fine then. I can't think of a reason it would not work.

Re: Gripper SW on 90's

We just installed expander boards in our old SS chassis's with Omega Tek boards. The eight lanes that were converted are having problems. One lane will pick up a full set and go into a strike and make a mess out of the cells. ( we grounded out a wire for now ) We have tried cameras, all new SA's and TA's, switched chassis's around, switched CWC's, called the factory reps MANY times, tripple checked all the wiring and other stuff.
If we shut the mach. off for awhile and turn it back on, it might run normally for three frames or three games. Running without the OS sw hooked up didn't help either.
IF it was wired wrong, it wouldn't run some of the time correctly. It SEEMS to loose the camera function. ????? Any ideas?

Alan, Do you have 5 board chassis?? If you convert to Omega Tek with expander, or MP chassis, you will get a short strike cycle that takes the info straight from he scoring system. Saves a lot of hassle, you can then eliminate all your cell wired, and remove the table cable completely...Defiantly worth looking into.

<font size="2" face="Verdana, Helvetica, sans-serif">We had a similar problem when I installed a Omega-Tek SS/MP chassis. Turned out that the green wire in the wire harness that goes from the expander board to the C-1 plug was hooked up to the wrong relay. May want to make sure it is hooked up to the A2 terminal on the sweep relay.

Re: Gripper SW on 90's

JimDorsin...I have 5 board chassis with Omega-Tek boards, no expanders. Have Frameworx scoring, as far as I know, this system will not mate with the chassis to be able to do that. Or can it ?

Re: Gripper SW on 90's

I thought of only one problem...an off-spot.

You would have to remember to reopen the respot cells after an off-spot, otherwise the machine would stop for no reason.

Otherwise, I think it would work.

Re: Gripper SW on 90's

Its scoring that tells if it is a strike.Sweep goes to guard then runs thro.It is easier just to disable the tenth frame switch at the ball return and they can press all day and the pinspotter will not cycle.Then the mechanic can reconnect if requires for test etc.
I dont see the sense in trying to put the gripper switch thro the off spot or bin switch , as already answered above.On the 90's the table wiring is removed and there is no gripper protection wiring, so this is not even possible.it may work thro the off spot but the clevis activated the off spot switch so dont see this as an option.
anyway i would be very pleased to hear how you get on with your idea.
Good luck.Nothing ventured nothing gained.

Re: Gripper SW on 90's

Alan, I am not sure, but I dont see why it souldent. I would suggest calling both Omega Tek and your framworks tech and ask them. If it will interface, It is a good investment. We have Qubica, and it works fine. keep me posted, I am interested to hear the awnser.

Re: Gripper SW on 90's

As a note, we disconnected our ball return buttons about 5 years ago. One of the best things we could do. We have auto-triggering that works exteremly well and we keep our cushion switches working as a backup.

By not having the reset buttons plugged-in, we no longer have the kids messing around during the glow bowling cycling the machines while bowling....
