Troubleshooting 7
Introduction
Introduction |
This section provides troubleshooting information in three parts. First a listing of all 5725A fault codes is provided for reference in Table
5725A Fault Codes |
Table
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
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.
