Note

This chapter provides a preliminary introduction to the power supply front panel. See "Chapter 5 - Front

 

Panel" for more details.

Introduction

Successful tests in this chapter provide a high degree of confidence that the power supply is operating properly. For verification tests, see “Appendix B - Operation Verification”. Complete performance tests are given in the service manual (see Table 1-5 in Chapter 1). Do not apply ac power to the power supply until told to do so.

Preliminary Checkout (All Models)

1.Make certain that the front panel switch is off.

2.Examine the Line Voltage Rating or Line And Fuse Rating label (see "Chapter 2 - Installation" )

a.Verify that the line voltage rating agrees with your power source. If it does not, see "Appendix C - Line Voltage Conversion".

b.Series 664xA/665xA - Use a screwdriver to remove the line fuse from the fuseholder (3, Figure 2-1). Verify that the fuse is as specified on the label. Replace the fuse.

c.Series 668xA - Unscrew the fuse caps from the rear panel (2, Figure 2-4). Verify that the fuse is as specified on the label. Replace the fuse.

d.Series 669xA - Flip open the fuseholder located under the ac line safety cover on the rear panel. Verify that the fuse is as specified on the label. Replace the fuse.

3.Check the sense wiring as follows:

a.Series 664xA/665xA - The SENSE switch (4, Figure 4-3a) is set to Local.

b.Series 667xA - Remove the output safety cover (1, Figure 4-4a) and examine the output sense terminals (4 and 5). They should be wired for local sensing as follows:

1.The +LS sense terminal wired to the +S terminal of the analog connector (2).

2.The -LSsense terminal wired to the -Sterminal of the analog connector.

3.If the power supply is not wired for local sensing, make the above connections, using small-capacity wire (#22 is sufficient).

c.Series 668xA/669xA - Examine the output bus bars (Figure 4-5a) and make sure they are connected for local sensing as follows:

1.The + bar is wired to the +S terminal of the analog connector.

2.The - bar is wired to the -Sterminal of the analog connector.

3.If the power supply is not wired for local sensing, make the above connections, using small-capacity wire (#22 is sufficient).

4.Make sure that there is no load connected to the output terminals or bus bars.
