table problems

[mekanic]

we're running 82-70s with MPS. im having a problem with lane 6. it's happened to me 5 times. the table will just stop in the middle of spotting, or sometimes it will stop just as it is about to finish re-spotting at about 300 degrees. i changed the chasis and it still does it. when i get the call, i just hit the table relay and it finishes to home. when it stops during spotting, the sweep will finish normally. and the table is still down. any ideas???

Re: table problems

1 - check table cam cluster, make sure it hasnt migrated to where the cams are no longer hitting the levers.
2 - check C1 plug. next time it does it try jiggling C1 to see if that makes table move.
3 - but you say you just hit the table relay and its fine, sounds like table relays on both chassis need replaced.

Re: table problems

Do you still have frame counters at the front desk? If so the problem might be over there since the frame counter is connected to the spotting relay.

<font size="2" face="Verdana, Helvetica, sans-serif">if u had a multi meter that has a diode tester see if there is a brake in the cam wire or the cam switch is not f***ed other wise the rest you can cheak at the same time

the way we test our chasis coils on the sweep &amp; table we activate the cam switch and see if the realy is pulling in

just an idea

Re: table problems

How old are your MP chassis? The older ones didn't have a capacitor in the BS circuit. Unlike the SS chassis where the SP relay keeps the circuit closed, the MP's are susceptible to stopping as soon as the BS opens.

It's just a small 100mf disk capacitor. You can put it in the chassis or in the wireway. I'd have to do some research to remember exactly where it goes in either application. It's been a while.

Also check for bad backend CB as this is wired into the Spot circuit.

My schematic shows that the small cap needs to go over terminals strip #s 32 and 34. + end on 34 which is the common end of the switch and the - end goes on 32 which is the N.C end of the switch.
Hope this helps.

Re: table problems

Thanks guys, my MP was a spare &amp; the only MP in the house. Did the jump on the back side of the C-2-A.
