The screen might be blank on your Ulvac Power Supply because the required voltage has not been applied. Ensure that the correct voltage is supplied to the device.
What to do if RF-ON is red but there is no output on my Ulvac Power Supply?
If the RF-ON indicator is red but there's no output from your Ulvac Power Supply, it could be due to several reasons: if set to external control, the external command voltage may not be supplied; the output setting might be at 0 W; or if the OSC setting is EXT, there might be no OSC signal input. Ensure that external command voltage is supplied, adjust the output setting above 0 W, and provide an OSC signal when set to EXT.
Why does my Ulvac RFP-N Power Supply show a "DC SOURCE FAIL" alarm when turned on?
The "DC SOURCE FAIL" alarm on your Ulvac Power Supply indicates that the required voltage has not been applied, or there may be internal component damage. Check the applied voltage and inspect the device for any signs of internal damage.
Why isn't the output reaching the set value when RF-ON is red on my Ulvac Power Supply?
If RF-ON is red but the output doesn't reach the set value on your Ulvac Power Supply, it could be due to internal element damage within the RF Generator, a drop in external command voltage (if set to external control), or a matching issue. Check for internal element damage, monitor the external command voltage, and ensure that matching is achieved.
How to fix "INTERLOCK" display and RF not turning on issue on Ulvac Power Supply?
If your Ulvac Power Supply displays "INTERLOCK" and the RF won't turn on, it means that pins 16 and 17 of the external control connector ("EXT.CONT") are not short-circuited, or the matching box interlock hasn't been released. Check the short circuit of pins 16 and 17 and release the matching box interlock.
What to do if RF won't turn on after resetting the interlock and alarm on my Ulvac RFP-N?
If you've reset the interlock and alarm on your Ulvac Power Supply, but the RF still won't turn on, it may be because you're not in the correct mode for external control or panel operation of RF-ON/RF-OFF. Alternatively, there could be damage to an internal component. Ensure that the correct mode is selected and check for any internal component damage.
Why is the control panel text garbled on my Ulvac Power Supply?
If the text on your Ulvac Power Supply's control panel is garbled, it might be due to noise. Try turning the breaker off and on to see if the issue resolves.
