3.1 Basic Construction

3.1.1 Overview of Electrical Circuit

0013-3455

The machine's electrical mechanisms are controlled by the ADF controller PCB (microcomputer CPU). The
CPU interprets signals from sensors and the host machine, and generates appropriate signals to drive such loads
as motors and solenoids at such times as programmed in advance.
