MinhPhong29 Posts: 30 Rating: (2)	Hi everybody, I have a problem now. When I connected Pt100 2-wire to signal board SB 1231 RTD, a red led on the SB and error led on CPU was flashing. I don't know why? Can anyone help me? Thanks! P/S: I'm sorry for my bad English Attachment pt100 and sb1231.jpg (596 Downloads)

MinhPhong29 Posts: 30 Rating: (2)	Hello Marcja, Yes, I have checked my connection, it correctly as picture attached. One more thing, when I used online function to monitor, I saw an error "High limit exceeded" on Diagnostic and the value of PIW80 = 32768. Do you know why? Thank you! (Sorry Marcja, my English is not good, so do you understand? )

MinhPhong29 Posts: 30 Rating: (2)	Hello Marcja, Thank you for replying me :) I have measured the resistance of PT100, It was approximately 110 Ohm at 26 degrees. So I think my sensor have no problem.
