When enabled, there is a DIP switch for each control input and the feedback output. The individual DIP switch interprets the input or output voltage as a CFM signal or position signal. If the switch is set for CFM, the signal represents the CFM scaling the UVM is setup for.

For example, if 1600 CFM is set at 10 V, an input of 10 V requests the valve is at 1600 CFM. Feedback of 10 V indicates the valve is at 1600 CFM. If the DIP switch is set to position, an input of 10 VDC requests the actuator is at 100%. The feedback Vo indicates the actuator is at 100%. There are separate switches for the input IN signal and the output Vo signal.
