  • No Spotting

    Hey guys, wanted some input here if I could. As we near the summer and things are slowing down I decided to take on the task of repairing old chassis (SS's with MK-70's and expanders) that we had laying around. Started on one today, had a note that said no cycle. Tinkered with it, swapped M and M2 and boom, it cycled (I also replaced this relay with a new one just to be 100% safe), great right? Wrong! Now it cycles as it should (shortened cycles are fine, respot is fine) but it will not spot pins, I changed the SP relay and put a known good one in, still no go, checked wires to SP relay socket, couldn't see anything there. Replaced the c-1 pin for the spotting solenoid still nothing, it doesn't fire at all, are there any other pins I can check for the solenoid? The one pin I changed (dunno letter or # offhand, but it was in the 2nd row from the top and the 4th in from the left). The problem is definately in the chassis as I tried it on more than one machine. Any other ideas for me to try tomorrow? Thanks in advance guys [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

      Re: No Spotting

      Thanks for the reply. Honestly I don't know if it was spotting before the loss of cycle or not, as I said this chassis was sitting around for years, it's been slow recently so I wanted to get us some working spares, but I'd assume it was working before. I'll try your tips tomorrow and see what I come up with, thanks [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

        Could be a bad spot socket (assuming it wasn't spotting before). Check to see if the spot relay is actually pulling in when it is supposed to. If it isn't, try "twisting" it a little during the spot cycle and see if it pulls in. If it pulls in, replace the socket (great fun) [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]
        If you are using old relays, the ohmmeter test of the coil won't tell you much. If the coil is shorted, it will become VERY apparent, VERY soon (meltdown). The problem with a LOT of older relays is the contacts get pitted and/or oxidized and even if they are pulling in, might not be making good enuff contact to do the job. Use the old relays for target practice and get NEW ones! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

          It could be the socket possibly, the SP relay I used I KNOW was good, I threw it in another chassis and it spotted fine, I tried a brand new one anyway still no good. I'm gonna recheck all the wires for about the 95th time today, maybe I missed something. Thanks again for the help guys, I'll keep ya posted

            Re: No Spotting

            Got it guys! I should've known it'd be something stpuid. If whoever pulled the chassis didn't think to check the relays naturally the jumper board in #3 would be backwards too (which I didn't catch yesterday) flipped it around the proper way and boom! Fully working chassis, I made a crucial mistake which I try not to, I didn't start simple :p Thanks again for the replies guys [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

              When you say, Itwont spot, do you mean that the table runs through a spotting run but doesnt pull in the spot solenoid or does it just sit there like its waiting for the spot relay to pull in. If you can feel the relay pull in then your micro switches are OK and the problem is in the 110 volt wiring to the solenoid. Ihope this helps

                Damn!!!!! I type so slowly that he fixed it before I got it posted. Its funny but one of my centers did the some thing last summer when they installed the OTECS. they felt real bad when I charged them 36 cents a mile.

                  Re: No Spotting

                  It is fixed, but to answer your question it basically just ran a respot cycle. table ran to respot height and opened or closed the fingers nothing more heh All better tho, things are looking good so far in my little project, I got 3 chassis fixed and ready to go [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

                    Good luck with your project Rep. I did the same project about 2-3 yrs ago. I had 5 chassis that had been collecting dust for about 15 years. 1 had already been cannibalized, so I took out what was left for parts. (4 left) I had to cannibalize another one to get enough parts for the others. (3 left) One of them blew up beyond (what I wanted to) repair when I applied power to it to find out what was wrong with it. The other 2 turned out OK. It wasn't a fun project but it's nice having 2 spares. They went several years without a spare before I went on full time. [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

                      Just something to keep me occupied really, I know 5 of the 6 bad chassis we have sitting on the floor have been sitting there since I started 6+ years ago and god only knows how long before that (down to 3 bad now as I fixed 3 already). I got all 3 on one side up and running like new and the only parts I used was a 24v relay and some 3 amp slo blow fuses. There's 3 more on the other side waiting for attention, those are next on my list. Going well so far though, we have 3 more spares now then we did before [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]
