  • No cycle start

    Hi Everyone, its been a while. However I have a chassis problem that I just can't figure out. I have five board chassis with Omega single board. The board is good as I put the board in another chassis and all works well. I've changed all the relays, and contactors, fuses are all good. I can run the sweep with the sweep run switch. I can run the table with the table cam. The sweep will not run from the sweep cam. some other component must be bad. Help!!

    Re: No cycle start

    If you can't run the sweep from the sweep cam, maybe the switch is bad. Did you try the chassis on another machine, and did you try a different chassis on the problem machine? I would also investigate the manager control circuit. There could be a short and the machine might be on instructomat. The front desk switch would be a good place to start, after that go the AM&C box.
    Give me a hammer and some duct tape and I can fix it!

      Re: No cycle start

      I'm with 8270 here, bad microswitch possibly or something bad in the wiring of the SA cam microswitch (broken wire, bad connection, etc). If not could be something in the chassis. As he stated try swapping the entire chassis with a good one and see if the problem moves with the chassis or the good one fixes it on the problem lane. However I don't think its anything with managers control, I dont believe you get sweep run from the switch if instructomat is on.

        I thought the sweep would run from the switch no matter what, but I could very easily be wrong. Sorry for the confusion.

          8270 no biggie man [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img] I'm not 100% sure on it but if memory serves I dont think you get sweep run from the switch on the control box in instructomat. I remember the night manager messing with me on a Saturday night when I was putting in colored pins and throwing one in instructomat and I tried just doing a sweep run and it wouldn't work from the control box. Not 100% sure but I'm pretty sure on it [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

            Ron, sounds like a bad diode on the SP relay socket. Take the bottom cover off the chassis and unsolder 1 side of the diode then throw it on a machine to test.

              The sweep will run in instructomat from the rear contol box.

                JJ,

                Is that diode under the SP relay needed at all?

                  Jerry, if you take it out you loose the frame meter at the control desk but the machine will run fine.

                    At the risk of sounding over confident, I can tell you that if your sweep will run from SWS but not from SA, you are definitely in instructomat, though it may not be from the managers control unit/switch. Could be a shorted wire in the managers control circuit, grounded to any house or machine ground. Two age-advancers that I experienced, both time after some serious down time:

                    Found a pinched mask cable at the pipe hanger. The cut wire grounded to the pipe was the one from the mask safety switch.

                    Noticed a broken A&MC plug on the front of the machine (C23 & later). Someone must have stepped on it or kicked it while climbing in or out. Pin # 21B was touching the guide pin, completing the ground.

                    To isolate the problem (eliminate everything outside the machine), put the pinspotter into complete standalone:
                    1) If you have an ON/OFF switch in the control box, turn it to the OFF position.
                    2. Unplug the PM and jump #2 to #28. This will close the mask safety circuit.
                    3. Unplug the A&MC and jump pin #21 to 22. This will turn the machine on.
                    4. Since you're in the front of the machine doing the A&MC, try to run the sweep via SA. If it runs, the problem is before the machine, such as the A&MC plug/cable, A&MC box, the 8-lane black junction box, managers control unit, or any wires in between. It may also be in the wiring from your ON/OFF control box switch to wherever it makes connection. Check by turning on the switch at this time.
                    If not, it could be in the A&MC receptacle in the machine or its wires going to C2A.
                    GOOD LUCK! [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

                      C-1 plug maybe? cycle start wire(pin) is letter Z I think.

                        C-1 has nothing to do with cycle operation. Cycle is a Low voltage deal. 24 volts..not 120.

                          Hey Deadwood, I run the old set-up with the Neon lights on the #1 board and they put out -160 volts DC through the C2A plug. But your right, the high current passes through the C1 plug.

                            Thanks for all of the suggestions. I'm sorry I forgot to tell you that another chassis will work fin on that machine, and yes the problem moved with that chassis, so I;m pretty sure the chassis is at fault. I'm going to try the thing with the diode. Thanks Again.

                              The diode thing worked for part of it. I et a cycle start, but pin spotting. Tried a new sp relay but didn't fix. Anything else? Thanks Again
