SECTION 4

Troubleshooting

This section contains a troubleshooting guide to help locate and repair failed components. This troubleshooting guide is designed as a general reference only, and will not cover every possible component failure. It is possible for problems with theflow instruments to appear as a failed power supply and vice versa. Therefore, if possible, try to verify the proper operation of the flow instru- ments on a different power supply. The components and test points mentioned in this section can be located by referring to the component layout drawing in Section 6.0.

NOTE: SOME OF THE TROUBLESHOOTING PROCEDURES WILL INVOLVE RE- PLACING FAILED COMPONENTS ON THE PRINTED CIRCUIT BOARD. DO NOT PERFORM THESE STEPS IF THE POWER SUPPLY IS STILL UNDER WARRANTY, SINCE PRINTED CIRCUIT BOARD MODIFICATIONS WILL VOID THE WARRANTY.

Some components on the PC Board are at HighVoltage, only qualified personnel should perform this test.

4.1 Test Points:

Refer to Figure 4.1. Test point 1 (TP-1) is common. All of the voltages specified in this section are referenced to this point unless stated otherwise. These voltages should be checked under load condition. Test point 2 (TP-2) is the output of the positive regulator and should read between +14.25 and+15.75 VDC. Test point 3 (TP-3) is the output of the negative regulator and should read between -14.25 and -15.75 VDC. Test point 5 (TP-5) is the voltage applied to the front panel display. Since the display is a miniature digital voltmeter, the voltage on TP-5 should be the same as the number on the display.
