  • Steltronic A2 Wiring - 12th Ball

    We are currently installing the Steltronic Focus scoring system with our Brunswick A2 machines.

    The API we are using is 065. There are 2 wires coming out of pins 4 and 5 on the connector for CN7. According to the wiring diagram that we have for Steltronics, those 2 wires should control the ball cycle functionality. The cycling functionality appears to work just fine except for the 12th ball. When a bowler gets a mark in the 10th frame and the pinsetter needs to be set on the second ball for the last throw, the pinsetter will not get set to the second ball. It is on the first ball every time and requires a manual recycle for the end of the frame.

    Does anyone know what could cause this or the exact connection for these 2 wires on the pinsetter? Any help would be greatly appreciated.

    Do your machines have New Pin Solenoids fitted?

      Those wires are just normally open relay contacts on the Steltronics. The connect parallel to the cycle button which is CN2 (two wire connector) on top of Pinsetter electrical box.

      There is a configuration setting to enable the 10th frame respot. Did you make sure this is set?

          Make sure that "New Pins Solenoid" is activated in Steltronics.

          We are running our A2s without the NPS, so the pinsetter just goes thru an extra cycle (lots of rake hits w/ open play though). We had to play with the delay adjustment to get it just right (cycle solenoid would fire before pinsetter was ready).
