Why doesn't HV ON work even after pressing the ON button on my Ulvac Power Supply?

  William BriggsSep 8, 2025
  If HV ON does not work even after pressing the ON button on your Ulvac Power Supply, it could be due to several reasons: * HV SWEEP not working: Consult Section 5. * INTERLOCKS connector issue: Check the INTERLOCKS connector, specifically the contact between Pin 7 and Pin 8, referring to Fig. 4.7 for wiring and contacts. * KEY switch in LOCK state: Ensure the KEY switch is in the LOCAL mode, not LOCK mode.

  If the Ulvac Power Supply cannot be switched to ON, consider the following possible causes and solutions: 1. **No power received**: Check the power supply in your fuse box and ensure it is receiving power. 2. **Panel interlock active**: Verify that the panel is properly in place and that the panel mounting screws are not loose. 3. **MAIN circuit breaker broken**: Determine if the breaker trips even when the power supply in the fuse box is in the OFF state. If so, replace the breaker.

Why does the fuse blow when the high voltage is switched ON in my Ulvac HPS-1600F Power Supply?
- D
  deckerangelaAug 29, 2025
  If the high voltage is switched to ON and the fuse is blown in your Ulvac Power Supply, it could be because the beam current command signal is maximized. Check the command signal of the beam current. A large inrush current may pass at the instant when the high voltage is switched to ON if the signal is maximized.

- R
  Ryan GrahamAug 28, 2025
  If no beam current passes with your Ulvac Power Supply, verify the following: * Check that a high voltage is applied. * Confirm that it is not in DEGAS mode and release it if it is. * Check the wiring of the filament line. Also, consider potential issues on the loading side, such as poor insulation or contact of the filament line due to assembly failure of the EB gun, or dirt on the isolation insulator.
