3-2 Section 3: Pinsetter Electronics
The CPU gathers switch information and sends out solenoid voltage to each pinsetter through the I/O
board. The CPU also supplies power for the D/C pinlight and the masking unit 1/2 ball lights through
the I/O board. Communication to the scorer is also handled by the CPU.
3-phase power is supplied to the High Voltage board through power contactors that are monitored
through an emergency o interlock system. The High Voltage board supplies power for the ball
accelerator, pinsetter string wagon motor, and optional A/C pinlights. Refer to Figure3-2.
