sweep overload/interlock issues

[slb785]

Im scratching my head here. Can't figure this one out for the life of me. Every night, 2-3 times per night lane 22 will either interlock, or the sweep motor will overload. The sweep overloads maybe 3 times for every one interlock. Iver done everything I can think of, best I've done is gotten it to go away for a day or two. But it overloaded now twice to tonight.

Tried 2 separate motor heads complete with new bowl tronics switches
Changed chassis, ended up rebuilding 22s chassis, new contacts, cleaned out, repined c1 and c2 plugs on both sides (machine and chassis)
Took apart sweep plug on the machine and inspected, all is well
Inspected sweep plug wiring in the sideways, all good. Tested continuity just to be sure
Changed sweep and table capacitors
Even tried unplugging the triggering to see if if was sending multiple cycle signals that somehow might of screwed it up.

Im lost. I've been dealing with this for 2 months and it wont stop. Im going to see if maybe the gearbox is really stiff and putting an excessive load on the motor. Its the last thing I can think of. What else should I look at that would cause a motor to overload?!

they tell me the Gearbox being stiff is the next place to check. it wouldnt happen to be overloading as its running up out of 2nd gaurd would it?

[slb785]

No it usually overloads at 0 when its first told to cycle

[Grit]

ahh we are suffering from different issues then. sounds like you've pretty much tried everything I have, however I did have this happen once before. Last time this was happening I had some really torn up aluminum sweep parts...as in all of them were about to be ripped apart at the pivots.

If I might suggest you check out the pivots and capacitors in your wireway if you haven't done that yet.

Sweep run and sweep reverse switches haven't been mentioned.

Yeah I once had a machine at one of my old centre's where it wouldn't do anything just hum.... turned out to be a dead sweep reverse switch....

[slb785]

Ill try swapping the switches with known good ones and see if the problem moves. I hate intermittent electrical problems!

[maister]

sounds like a bind somewhere, does it wind through ok. It could be the crankarm moving sideways and fouling against the bolts.The gearbox also seems a good suggestion.

Its never bound up or stuck on anything when I get the call. Either simply clear the interlock or just hit the klixon and it runs normally. Most of the calls the sweep overloads right at 0 before it even moves

SLB if you have MP chassis check the M2 relay pins for burns and if that looks good swap it with either of the other 2 and see if that helps.

[slb785]

SS chassis

With AS90 there aren't any quick cycles correct,so there is no sweep reverse relay in the backend control box?

[slb785]

Nope. I don't have any tenth frame switches either

[keeth]

Well damn you are just full of bad news
