Troubleshooting 7

Introduction

7-1. Introduction

This section provides troubleshooting information in three parts. First a listing of all 5725A fault codes is provided for reference in Table 7-1. Following that is a description of 5725A automated self-diagnostics that you run from the 5700A. Finally, some manual tests are provided that can help you isolate a fault.

7-2. 5725A Fault Codes

Table 7-1 lists all 5725A fault codes. Fault codes and descriptions appear on the 5700A Control Display in fault conditions. The codes and descriptions can also be transferred from the 5700A in remote control operation. Where fault messages are not self- explanatory, additional explanation is given in the table.

7-3. Self Diagnostics

The best way to begin looking for the source of a fault is to run self diagnostics from the

5700A diagnostics menu. To run self diagnostics, proceed as follows:

1.Press the "Setup Menus" softkey. (If "Setup Menus" is not showing on the Control Display, press RESET first to return to the 5700A power-up state.)

2.Press the "Self Test & Diags" softkey.

3.Press the "5725A Self Diags" softkey.

4.Begin testing with the voltage function. Press the "Voltage" softkey. A sequence of self tests is run. A brief description of each test follows:

a.5725A ACV Sense Amp: Checks for proper operation of the high voltage sense amplifier on the High Voltage Sense Assembly (A6).

b.5725A ACV Standby: Puts the 5725A into voltage standby mode, and causes the analog monitor circuit on the High Voltage Sense Assembly (A6) to cycle through the continuous tests it does during normal operation.

c.5725A ACV Operate: Puts the 5725A into voltage operate mode, but disconnects the output from the 5700A binding posts. This test makes sure that the High Voltage Amplifier (A3) works correctly, and checks the analog monitor circuit on the High Voltage Sense Assembly (A6) for correct operation.

d.5725A Cal Sensor: Verifies that the calibration circuitry on the High Voltage Sense Assembly (A6) is working correctly.

5.This completes voltage function testing. If any of the self tests fail, a fault code and message is displayed.
