I have 2 Chassis with Omega Tech Boards where the sweep is going up from 2nd gaurd on TA1. I thought it was the boards but those boards work fine in other chassis. What am I missing? It doesn't seem to be causing any problems but it looks bad.

Re: 8270 Chassis
You have older Omega tek boards. Newer Omega tek boards raise the sweep on TA2 which doesnt look bad. If you are really that concerned about it you can send the board back to Omega tek and they will will modidify it free of charge. Just make sure you put a note on the board explaining what you want done.

Re: 8270 Chassis
I believe that the boards manufactured in 1984 and before run of TA1 to lift the sweep to gaurd. You can find the date of production stamped on the corner of the PCB.
I also have one board like this and I dont like the table being that exposed. Especially with the types of open bowlers round my way that seem to close there eyes whilst bowling!
Machine? what machine??Bring me the freshest "Mean Green" known to man! Juice on!

Re: 8270 Chassis
Like these guys say, the older boards will do that (just like the 5 boards did) exposing the table for a breif moment, newer boards allow the table to go to 0 before the sweep raises.I've had enough of hope & chains.

Re: 8270 Chassis
Very strange. Are there any differences in the jumper board in the #3 slot?
Also, the old Omega-Teks have two different ribbon cable assys. Maybe this is where the difference lies. Don’t know…very strange.

Re: 8270 Chassis
Our machine have had their TA1 and TA2 N.O. wires swapped (in the wireway). This causes the sweep to wait until TA2 to raise with the table - and worked when we had 5 boards. So you don't need Omegas to get this feature if you want it.
We now have Omega Teks, so the TA1 N.O. input (which is actually TA2 N.O. on our machines) is no longer used (hence our wireway mod became redundant, but was retained since it didn't hurt).
In darkhalf's case, I'm not sure if the mod has been done in the chassis wiring or the machine wiring. If you move the chassis and the behaviour moves with the chassis (which you alluded to), then the mod must have been done in some of your chassis (and not others).
One possible chassis mod might be moving C2A-39 to C2A-25 (assuming C2A-25 is empty on the chassis and connects to TS-32 in the wireway, which it does on ours). BUT! It depends on your existing machine/chassis wiring and what other mods have been made (and I have not tried this, so don't sue me if your machines blow up [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] ).
If the behaviour actually stays with a machine, then you could find out where the mod was done (probably two wires switched in the wireway at TS32 and TS45) and copy it to the other machines.
Note: you cannot have mods in some chassis and some machines. Different mods might not play nicely, or may cancel eachother out!.

Re: 8270 Chassis
you can go into the cams on the table side and switch the grey and brown wires and that pesky little thing will go away. All this does is make the sweep wait for the table to go up. I've had alot of 5 boards that have done the same thing.They say that the **** rolls down hill but the smell always starts at the top.

Has anyone of you checked if the 90xl chassis use TA1 for 2nd guard to home for sweep?
