Valve Override Signal (Analog I/O version only)
The Valve Override Signal (VOR) is implemented as an analog input which
measures the voltage at the input and controls the valve based upon the
measured reading as follows:
Valve Override Signal Drive Settings (Analog I/O Versions only)
Floating / Unconnected: Instrument controls valve to command setpoint
VOR < 0.3 Vdc:
Valve Closed
VOR > 4.8 Vdc: Valve Open
