Figure 19. First Ball Foul - Brunswick A-2
First Ball Foul
On a first ball foul, the New Pins Solenoid switches the detector to second
ball. On a first ball foul, when the New Pins Solenoid switches the detector to
the second ball, the cycle link and crank generates a strike in the detector. It
then blocks the scissors and prevents the pinsetter from picking up the
standing pins.
1. Bowler delivers his first ball and fouls.
2. The ball breaks the ball detect's light path and triggers the pinsetter.
Refer to Figure 19.
3. The New Pins Solenoid switches the pinsetter to the second ball at 44 o ,
selecting a strike cycle.
4. The scorer displays an "F" and scores a "0."
5. 144° switch closes, but no action is taken.
6. The pinsetter sweeps the pins and sets a new rack of pins.
7. The New Pins Solenoid switches the pinsetter to second ball when the
0° switch closes.
8. The 0° signal resets the scoring cycle to accept another ball detect.
7. The 0° signal resets the scoring cycle allowing the VPS to accept
another ball detect.
