Power Supply Route
0009-2525
When the power of the host machine is turned on, 24 VDC is supplied from the host machine to the finisher controller
PCB through two power supply lines. 24 VDC supplied through one power supply line is used to drive motors and
solenoids. 24 VDC supplied through the other power supply line is converted into 5VDC by the regulator IC (IC102)
on the finisher controller PCB and then used to drive the sensors on the PCB. Furthermore, it is converted into 3.3
VDC by the regulator IC (IC109) on the finisher controller PCB and then used to drive the ICs on the PCB.
If the Puncher unit, which is an optional, is installed, they are supplied to the punch controller PCB as well.
24VDC for specific motor drives is cut off when the front cover switch (MSW101) is open. This is not applied to
the optional puncher unit and some other motors.
A block diagram of power supply is shown below.
