Yes, another 10401 Error... Occurring only on one out of two NI 4350 with TXB68-T.

[Roger Fontaine]

Hi all,

First thanks for taking the time to read me.

As mentioned in the title, I have one out of two 4350 that gives me errors in the Max software. Actually, when I start the MAX software and try to access the test panel of the unit in question, I get a message saying that the unit did not pass the test and asks if I want to continue anyways.

If I decide to continue and try to make readings I get a 10401 error and all read values are 0. And yet the other device works fine... ?!

I first noticed a problem when I ran my application which successfully controlled the 1st 4350 while the second was not responding. After looking at the unit that was not working I noticed that the LED was flashing. I reset the unit and the software and it did not solve the problem. After reseting the unit, the led came on, then off, then started to flash.

Do you have any idea what could be the problem with this 4350, what is the source of the problem and ideally what is the fix ?

See attached files for detailed error messages.

Kind regards,

Roger

Hi Roger,
I believe this is the issue you called in about. Please let us know if you have additional concerns.

Hi Brian,

This is exactly the case I called you about.

In our last conversation, you were supposed to call the R&D department to identify the specific causes that would trigger this failure mode identified by the led flashing pattern. It has been more than a week now and I have not heard from you on this topic.

As mentioned, I sure would be interested in knowing what triggers this failure mode, why the system is not capable of falling back on it's feet, what type of hardware protection is included in the NI 4350 and most importantly, how to prevent this failure mode.

A prompt response would be greatly appreciated.

Kind regards,

Roger

Roger,
Did you not get the email I sent? I show that it left our database, perhaps there was a delivery failure. This is what I wrote:
Hi Roger,
I checked with R&D on what could have caused 4350 power failure. It's
usually caused by inputting a voltage that's outside of the range of
the input limits (even transient overvoltage) of the 4350 or
incorrect connections. Always carefully connect according to the 435x
manual at the following URL:

Hope this helps!
