Hi
Im really confused. I have a 4-ch analog OUT module (Mitsubishi FX2N-4DA), i have used the three (3) channels. Just this evening, I did connect to the 4th channel a 4-20mA controlled air regulator..and my problem has started.
Connected on my 1st channel was a VFD (0-10Vdc), 2nd channel was a temperature controller (4-20mA) and 3rd channel was a VFD (0-10Vdc). If I connect my air regulator analog signal on my FX2N-4DA module, I get an error on my temperature controller (OMRON, E5En-H) which reads E333 (referred to the manual, it is A/D converter error which is probably cause by noise).
I disconnect my air regulator and the error was OUT. I connect my air regulator and the error is IN.
I disconnect the temperature controller & connected the air regulator still on 4th channel. I am controlling fairly well. Connecting temperature controller on 2nd channel, then the error is IN AGAIN.
I exchange my channel 3 & 4, but still conflict between two 4-20mA signals are still observed.]
What would be the possible error?
Pls. help me
