If, when turning the EMISSION knob, fuses F14 and F15 or F24 and F25 are blown on your Ulvac Power Supply, it is likely due to a short circuit of the filament line of the emitter assembly. In reference to the operations manual of the EB gun, check the emitter assembly.
What to do if OVERLOAD blinks when high voltage is switched ON on Ulvac HPS-1600F Power Supply?
If the high voltage is switched to ON and OVERLOAD blinks on the screen of your Ulvac Power Supply, it is likely due to abnormal electric discharge on the loading side. This can be caused by dirt. If the issue persists, perform maintenance on the high voltage line and the EB gun.
Why is the Gun controller READY indicator not lighting up on my Ulvac HPS-1600F?
If the Gun controller READY indicator on your Ulvac Power Supply does not light up, check the following: * **SERVICE KEY settings**: Ensure the SERVICE KEY is in the ENABLE state, not LOCK mode. * **Fuse indicator**: Check the fuse indicator of the power supply main unit. * **Fan rotation**: Make sure the fan is rotating and remove any foreign substances that may be stopping it.
Why does no beam current pass through my Ulvac HPS-1600F?
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.
Why does the fuse blow when the high voltage is switched ON in my Ulvac HPS-1600F Power Supply?
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.
Why is remote operation not available on my Ulvac Power Supply?
If the remote operation is not available on your Ulvac Power Supply, check the following: * Ensure it is not in LOCAL operation mode by checking the LOCAL/REMOTE settings. * Verify that an external signal is being input by checking the program connector and the external signal sources.
Why does HV SWEEP not work on my Ulvac HPS-1600F Power Supply?
If HV SWEEP does not work on your Ulvac Power Supply, check the setting of the INT/EXT switch on the M- CONT board inside the power supply unit to ensure the waveform input switch is not set to EXT.
What does it mean when the FUSE indicator is turned off on my Ulvac HPS-1600F?
If the FUSE indicator is turned off on your Ulvac Power Supply, and fuse F14 (or F24) on the back of the power supply is blown, it indicates a short-circuit in the filament circuit. Check the emitter assembly, referring to the operations manual of the EB gun. Verify whether there is a short-circuit between the right and left filament terminals.
Why doesn't HV ON work even after pressing the ON button on my Ulvac Power Supply?
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.
What causes the Gun controller indicator to turn off with the key switch at LOCAL on my Ulvac Power Supply?
If the Gun controller indicator is turned off with the key switch at LOCAL on your Ulvac Power Supply, check the connections of the interlock on the equipment. Also, check whether there is a ground fault of the interlock signal.
