BOP HIPWR 111315 2-72. With no load connected, set POWER switch to the ON position. Each time the unit is turnedon an internal self-test is performed. The alphanumeric display (LCD) shows the processorfirmware revision history and lists various tests performed during the internal self-test. Aseach test is completed, PASS or FAIL is displayed. If all tests pass, the unit goes into thedefault mode. If a failure occurs, the failure is displayed. Figure 3-3 shows the factory config-ured power on defaults displayed on the LCD.3. Connect a digital voltmeter (DVM) (resolution and accuracy of 0.01% or better) to theOUTPS and COMS terminals at the rear panel terminal block.4. Use the keypad to enter the rated maximum voltage of the power supply (e.g., enter 36 for amodel BOP 36-28MG) and press ENTER. If STANDBY indicator is lit, press STANDBY key.5. Verify DVM voltage reading agrees with programmed voltage within 0.03% of rated maxi-mum voltage and agrees with displayed voltage on LCD within 0.05% of rated maximumvoltage.TABLE 2-11.
