sveremey Posted May 20, 2020 Share Posted May 20, 2020 Hello, I found this thread but I'm still having an issue on a system we're working on. http://forums.deltatau.com/showthread.php?tid=1005&pid=3878 We have 2 ACC-59E3 cards in our rack, and we intend for one to be voltage inputs and the other to be current inputs. Following the manual and the post above, we set the jumpers to 2-3 on the desired "voltage" card, and 1-2 on the "current" card. This seems to be backwards somehow. Can anyone else confirm this? I can't communicate from the job site and I need to be back there tomorrow, hoping I can get some confirmation before I go in and have a look at it again. Thank you!

Smakarem Posted May 20, 2020 Share Posted May 20, 2020 Hi Steve, I don't quite have an ACC-59E3 on hand as I am working remotely. But I can confirm that per our manual jumpers 2-3 are for voltage sensing mode and jumpers 1-2 are for current sensing mode for the specified ADC. 1. Can you clarify what you mean when you say "it seems to be backwards somehow". What are you seeing on your end? 2. Are you able to decipher which pin is pin 1 on the PCB for the jumpers or is there no description? Kind regards, Shadi Link to comment Share on other sites More sharing options...

I have good news, there is no issue with the card or the documentation, although it is very confusing because of the orientation and arrangement of the jumpers. We were supposed to have 0-10V devices on our system but they were actually 4-20mA devices, so it appeared that things were opposite when the were not. We resolved this as soon as we took a look at all components, so this is not a Delta Tau issue after all. Thanks again! Link to comment Share on other sites More sharing options...
Smakarem Posted May 22, 2020 Share Posted May 22, 2020 Steve, That's great, glad to hear it was quick fix. Kind regards, Shadi Link to comment Share on other sites More sharing options...
