If the Gun controller panel does not light up on your Ulvac Power Supply, check the connection of the POWER and CONTROL cables.
Why can't the acceleration voltage be applied as set on my Ulvac Power Supply?
If the acceleration voltage cannot be applied as being set on your Ulvac Power Supply, consider the following: * Check if HV SWEEP is enabled. If so, refer to Fig. 4.6 and set HV SWEEP again. * Verify that you are not attempting to set a high voltage on the side of source 2, as it is not possible.
Why is remote operation not available on my Ulvac HPS-600N?
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 the fuse blow when the high voltage is switched ON in my Ulvac 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 does no beam current pass through my Ulvac HPS-600N Power Supply?
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 is the Gun controller READY indicator not lighting up on my Ulvac HPS-600N?
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.
What to do if OVERLOAD blinks when high voltage is switched ON on Ulvac HPS-600N 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.
