Appendix A – Using the Troubleshooting Screens 92
Stage 2. Score Determined
The second stage represents the expiration of the Take
Data Delay. This delay can be set from the Fine Tune the
Scoring Setup screen and is preset for each type of
Pinsetter. You should never need to change this Take Data
Delay, but if it is set too long you could see an image of the
Table on first ball and if it is set too short, you could see an
image of the pins still falling.
At this point the number of pins the Duo sees will be the
score reported.
A pin is determined to be present whenever the level of
brightness at the Pin Position Indicator is higher than the
threshold level. The Pin brightness is indicated by the
height of the bar in the bottom left of the screen and the two
horizontal lines on each side of the brightness bars
represent the threshold level.
This threshold level is calculated by the brightness of the pit area between the 6 & 10 pins on the Odd lanes and
between the 7 & 4 pins on the Even lanes. This level will automatically change as general lighting conditions change.
This means that the Duo scoring software is just as effective during disco and glow conditions as normal bowling. No
adjustments are needed to be made when changing from one condition to the other.
In this example, the default Delay from Score Taken to Pins Set is 6.0 seconds. Therefore, the next stage (Event)
will occur at that time.
Things to Check
If you are having scoring issues, check the following areas:
1. Make sure that the number of pins down equals the number of green bars in the Brightness section and is also
correct in the Player’s Score section.
2. Make sure that there are no red bars that are close to going over the Pin Brightness threshold. (Thus a pin being
considered present.) If any of these red bars are close to the threshold line, then there is a danger that variations
in lighting conditions from ball to ball could cause a pin to be falsely detected. Check to see if things such as oil
streaks down the curtain are causing the pit to look bright in the relevant area.
3. Check that the Pin Position Indicators are not being blocked by the Sweep / Rake. Usually, the Sweep / Rake
should be in the guard position when the Take Data Delay expires and the score is determined. Make sure that
rake is not blocking the pins and the deck/table should not be moving. This is particularly important with
Brunswick A2 pinsetters, because the deck will block the pit light and make the pins (especially the head pin)
appear dark, possibly dropping the light level below the threshold and causing the pin to be missed.
The only exception to this is a Brunswick A machine where the Rake and Deck move together on first ball. In this
case, the score is determined before the Rake falls. Make sure that the Rake is not blocking the pins.
