sented in this chapter is listed in Chapter 1, Table 1-1 (page 1-9).

SYSTEM DOES NOT

If the 373XXA does not power-up when connected to a source of AC power

POWER-UP

and the Power key is pressed, perform the power supply checks described

 

below.

 

 

 

 

 

 

 

 

 

 

 

WARNING

 

 

 

 

 

 

 

Hazardous voltages are present inside the instrument

 

 

when ac line power is connected. Turn off the instrument

 

 

and remove the line cord before removing any covers or

 

 

panels. Trouble shooting or repair procedures should only

 

 

be performed by service personnel who are fully aware of

 

 

the potential hazards.

Line Source and

Check as follows:

Interface Checks

 

 

 

 

 

Step 1.

Verify that the AC power source is providing stable power

 

 

at the correct line voltage.

 

 

 

NOTE

 

 

The 373XXA is designed to automatically

 

 

sense and operate with AC power line volt-

 

 

ages in the range of 85 - 240 VAC, with a

 

 

frequency of 48 - 63 Hz (540 VA maximum).

 

Step 2.

Verify that the power input cord is in good condition.

 

Step 3.

ensure that the system power line fuse is installed, that it

 

 

is not open, and that it is the correct value (8 A, Slow

 

 

Blow).

Power Supply Verify that the 373XXA power supply voltages are correct as follows:

Voltages Check

 

 

 

 

 

Step 1.

Press the 373XXA Power key off, and and disconnect the

 

 

power input cord from the 373XXA. ensure all external con-

 

 

nections to the system front and rear panel are also discon-

 

 

nected.
