Outline of Electrical Circuitry

The paper deck pedestal is controlled by signals from its host copier and from its own controller.
The copier sends signals as programmed in advance to the controller inside the pedestal.
In response to the signals from the copier and from its own microswitches and sensors, the
pedestal's controller generates signals to drive its motor and clutches.
Figure 2-201 is a block diagram showing the relationship among the pedestal's major circuits.
The pedestal is supplied with 24 V, 5 V, and 220/240 VAC by the host copier.
