Component Location and Circuit Diagrams

This chapter contains component location diagrams, schematics, and other drawings useful for maintenance of the power supply. Included in this section are:

a.Component location illustrations (Figures 6-1 through 6-6), showing the physical location and reference designators of almost all electrical parts. Components located on the A6 AC Input Board and on the output filter board mounted on the output bus bars are easily identified by reference designators silkscreened on the boards.

b.Notes (Table 6-1) that apply to all schematic diagrams.

c.Schematic diagrams (Figures 6-7 through 6-9).

AC line voltage is present on the A1 Main Board Assembly whenever the power cord is connected to an ac power source.

Table 6-1. Schematic Diagram Notes

1.	.	denotes front-panel marking.
2.		denotes rear-panel marking.

3.Complete reference designator consists of component reference designator prefixed with assembly number (e.g.: A2R14).

4.Resistor values are in ohms. Unless otherwise noted, resistors are either 1/4W, 5% or 1/8W, 1%. Parts list provides power rating and tolerance for all resistors.

5.Unless otherwise noted, capacitor values are in microfarads.

6.Square p.c. pads indicate one of the following:

a.Pin 1 of an integrated circuit.

b.The cathode of a diode or emitter of a transistor.

c.The positive end of a polarized capacitor.

7.In schematic symbols drawn to show right-to-left signal flow, blocks of information are still read left to right. For example:

žindicates shift away from control block (normally down and to right). • indicates shift toward control block (normally up and to left).
