Control valves (0...10V signal) Analog Output

If I just plug the data witht he constant 10 by example, I have this error.

 

Data-sheet of the valve : https://www.burkert.com/en/Media/plm/DTS/DS/DS2873-Standard-EU-EN.pdf?id=DTS000000000000000100017385...

Data-sheet of the connector of the valve : https://www.burkert.com/en/Media/plm/MAN/MA/MA8605-Manual-EU-EN.pdf?id=MAN0000000000000001000329112E...

 

valve is plugged, works and is configured to receive 0...10 V.

 

Labview error tell me this :

 

Requested Value: 1
Maximum Value: 18446744065119617024
Minimum Value: 2

 

yeah but I can plug 10, 5, 10000 or anything in data and the requested value is 1. Why ? It looks if I can request a value between 2 and 18446744065119617024, I can open my valve proportionally.

I searched but haven't found this parameter but I will look into it.

Again, what module in the cDAQ are you using for this?

 

I am seeing a big issue with your valve in that can require up to near 500mA.  Most DAQ modules come nowhere close to supplying that.  You might want to consider an actual power supply or add a buffer circuit to increase your current capacity.

I have a power supply and yes finally it works.

 

Actually I didnt know it was that simple. Add a number to data and that's it.

 

Now I have only 1 on 2 valves working so I guess I have an hardware problem now...

 

Thanks a lot all
