Programmable Analog Output Diagrams
The controller give the error "gauge error" if the gauge connected is
not supported. The pressure can be read by dispaly or by serial line
(win. 224) or by REMOTE I/O on Programmable Analog Out.
If the Programmable Analog Output is related to the pressure
read by an external gauge, the controller doesn't replicate
exactly the signal coming from the gauge; the controller converts
the gauge signal in the range from 0 to 10V.
The conversion formul is the following:
