The controller gives the error "gauge error" if the gauge connected is
not supported. The pressure can be read via display, serial line (win.
224) or REMOTE I/O on Programmable Analog Out.
If the Programmable Analog Output is configured to show the
pressure read by an external gauge, the controller doesn• t
replicate exactly the signal coming from the gauge; it converts
the gauge signal in the range from 0 to 10V.
The conversion formula is the following:
