Analog Output configuration

Hello

I am trying to configure an analog output in the DCS Freelance using AO890 remote I/O, to control manually this output I am using a Set Point Controller C_ANA connected to an analog output transformation, AO_TR and this block to the analog output (4-20 mA), but when I connect the AO_TR to the AO the line turns red and the loop doesn't works. I would like ton know if this configuration is OK?

Thanks for your help.
