Technical Operation:
Ball Drop Operation:
The balls are released by the solenoid plunger located at the end of the ball ramp. Once coined
up the game will start the game mode sounds. Pressing the Ball Drop button will send a signal to
the main CPU board. This board then relays the message to the Mini High Current Board which is
the board that then send the signal to the solenoid to release the balls. Once all balls have fallen
through the plunger will go back to its normal down position in anticipation for the balls to be
brought back up.
Wheel Position:
The wheel position is determined by the Home Optic Sensor and the step count of the Playfield Wheel Motor. There is a
small peg on the back of the wheel, when this peg passes through the home optic sensor it triggers a signal to the main
board. This signal
is to signify the Zero position. From there the Playfield Wheel Motor has a certain number of “steps”
as it rotates the wheel. These steps determine where the wheel is at
any given time. And help to score properly.
