DC Fail while setting the voltage for SM15K delta elektronik power supply

[Johnzahey]

I am facing a DC fail(blinking) error in the hardware which blinks while setting the voltage. i tried to ramp up the voltage but it doesn't solved the problem. How to solve this error?

unforutnately i cannot add the full vi but i attached a screenshot of it.

Were you able to find from the manual what that DC fail symbol means and what causes it?

[Johnzahey]

DC FAIL - This indicator is active if the DC power terminals are 5% below or above the set value for the voltage.

I tried to set the voltage through front panel at different speeds and is not able to reproduce it. however through the LabVIEW example i could reproduce and not able to set the voltage due to DC fail error

i used different ramp settings to eliminate this 5% requirement but still facing the error.

I see it as; the instrument does something automatically which you're not programming it from LabVIEW, most common scenario is that the instrument may be continuously adjusting the ranges or limits but you may be operating in the same limit or not changing the limit in the correct order before sourcing.

i changed the program source of power to front panel and is working now
