Circuit
The pressure is measured by means of a pressure transmitter. The
transmitter sends the measured pressure as a 0-10 V or a 4-20 mA
signal. The voltage signal can be applied directly to the input in
question. A current signal is converted by means of a resistor to a
voltage and then applied to the input. The measured voltage must
be converted to a pressure value by the controller.
The following procedure sets up the scaling:
Push the dial to see the graph and enter the value sets for the input
voltage (2 and 10 volt) and displayed pressure (in bar).
Pressure: 0.0 ... 30.0 bar
Fixed voltage settings: 2 V and 10 V
Factory settings: (2.0,0) and (10,20.0)
This means that the 'Pressure' is 0.0 bar at 2 V and 20.0 bar at 10 V.
Typically, the higher the voltage, the higher the displayed pressure.
