I have an altivar 61 VFD with a temperature transmitter and controller, the brand of temp controller is Delta DTB48. Our problem is that the altivar 61 analog input (AI2) and COM doesnt read 4-20mA output from the controller. But when we measure the controller's output with an amp meter we can get a reading of 4-20mA. We already verify the terminals on the Altivar (AI2 & COM) is ok and is able to measure 4-20mA. Kindly help me guys with this one... By the way 4-20mA is not a loop powered signal.
Thanks in advance!!!
