  • Pindication head scratcher

    I have AMF Mod V masks with pindication. Pinspotters are 82/70MP. Table cables are off. The machines that have 9850 MP boards work fine. Since we put in BOSS scoring, the machines with the 9860 MP boards always show the pin light on the mask that is grounded in the front wireway when the machine is cycled by the triggering unit. If you cycle the machine by the cushion, the mask will show whatever pins are standing. The scoring works correctly either way. Any thoughts? It's not a big deal, but it does get the occasional smart ass remark from the bowlers.

    The machine should show the 2 pin on RPO (scoring) respot.

      Omega-Tek MK70-EX boards do the same thing. It's the way they got the board to control 1st ball/2nd ball cycles. After the camera scans the pindeck, the board can turn on a pin signal to make the machine run a 1st ball cycle, or turn it off to have it run a strike.

      The pindication light staying on is just a side effect of that. Ours had the #1 light on... I just removed the bulb so it wouldn't show up at all, and later removed the #2-#10 lights, leaving only 1ball, 2ball, strike, and foul. There's pindication on the scoring screens anyway... and I noticed that the boards run a lot cooler when they're not driving the pinlights.

        I like that idea of pulling the bulbs out. I'm curious though as to why they function properly when cycled by the cushion but not when cycled by the triggering.

          Pete,

          The problem comes from a 'shortcut' designed into the 9860 board. It seems that the board was designed with a change from the MI design that never made it into production.

          The 9860 'score cycle' is actually a RPO cycle signal to the pinspotter. Only the strike, 7-10 pickoff, and gutter are directly operated by the camera. This causes the pinspotter to not receive camera data (as a RPO) signal, causing the chassis to read table cable data.

          We developed a fix involving the swapping of two pins in the MI cable, but I can't remember what it is off the top of my head. I can have my mechanic post or email you the fix if you are interested.

            Thanks Fever. At least now I know it's not something I hooked up wrong. If it's not too much trouble, I wouldn't mind getting the fix. Maybe post it here in case others have the same troubles and want to fix it.

            Thanks again!

              My mechanic says this is the solution to the problem...

              In AccuscoreXL and later scoring systems, when the machine is cycled via theBall Detector(BD), the BD signals the Machine Interface(MI) and the MI then cycles the machine through APS-21.

              APS-21 is connected to F-131 on the circuit board socket.

              Unfortunately, the 9860 PC board recognizes F-131 as RPO only, resulting in the behaviour you are seeing.

              To correct this, APS-21 should go to R-139 instead. The easiest way to do this is to cut the wire (usually purple) @ F-131 and move it to the switched side of the cycle switch on the side of the chassis.
