<strong>Brunswick</strong> A-2 Pinsetter Modifications<br />
Switch Cluster<br />
Figure 10. <strong>Brunswick</strong> A-2 Pinsetter Switch Cluster<br />
The Switch Cluster is a metal plate containing switches and cams that are<br />
mounted on the detector and is engaged to the detector 1:1 gear. The nylon gear<br />
that drives the cam shaft turns the cams which are timed to close the switches at<br />
proper times during the pinsetter cycle. Refer to Figure 10.<br />
(1) ADJUSTABLE CAM (2) 0º SWITCH (ZERO) (3) B-2000 SWITCH (NO LONGER<br />
USED)<br />
(4) 44º/144º SWITCH ("TAKE DATA")<br />
44o /144o Switch (“Take Data”)<br />
1. This switch closes twice every pinsetter cycle. The first switch closing<br />
will cause a “take data” signal when the deck is approximately 1" (44°)<br />
above the pins if the pinsetter is on first ball.<br />
2. The second switch closing will cause a “take data” signal at 144° when<br />
the rake is approximately 10" from the no. 1 pin if the pinsetter is on<br />
second ball.<br />
3. The switch is also used during special pinsetter cycles to energize the<br />
New Pins Solenoid during the first ball foul or No Tap cycles so any<br />
standing pin(s) will be swept away.<br />
0o Switch<br />
1. The 0° switch closes once each pinsetter cycle. It is used to reset<br />
memory on the Video Processing Board and allows it to accept the ball<br />
detect signal.<br />
2. Energize the New Pins Solenoid at the end of the first ball and third ball<br />
fouls, tenth frame cycles so that the bowler will have a second ball shot.<br />
