CHAPTER 2 OPERATION OVERVIEW
12.1.2 Overview of electrical circuit
The saddle stitcher sequence is controlled by the saddle stitcher controller PCB. A micro-
computer is used for the saddle stitcher controller PCB, and serial communication takes
place between the programmable controller and the finisher controller PCB.
The saddle stitcher controller PCB drives the solenoid and motor according to commands
sent from the finisher controller PCB.
The saddle stitcher controller PCB communicates information concerning the sensors and
switches to the finisher controller PCB by serial communication.
The roles of the main ICs mounted on the saddle stitcher controller are as follows.
•
Q1
Sequence control
•
Q2
Built-in sequence programme
•
Q3
Sequence control
•
Q4
