Hello, I need help setting up a "Accuload IV" flow computer. I already have the configuration partially done. It's for fuel delivery with two dispensing arms, each arm equipped with 2 flow meters and two digital control valves (for blending). I need to configure only one additive (colorant for blending), but I'm getting the following error (see image). For more information, please contact me at +591 77639936. Payment will be provided for the support.
