Is anyone familiar with these? I have recently retrofitted a pneumatic system using the FX 16 MASD app for N2, and have had a few issues. For example, the proportional heating valve output (no preheat) is 0-10vdc,Ihave installed a transducer, 0-10 in,3-15psi out to pneumatic valve actuator, cant find a good way of reversing the action on the output of the controller. 0 volts= 0 psi = full heat when I am not calling for it. The staged humidifier ouput will not make either. I am curious to know if anyone has experience to share.
