Run in signal
The sensor has a build in controller for a pulse modulating valve. The
sensor provides both the analog output via the cable to control the
valve. The level measurement signal for the PLC comes via the M12
plug .
On pin 3 it is possible to send an analog 4-20 mA signal to the controller
and change the setpoint. The signal is scaled linear like analog output.
The cable is connected according to the drawing and the parameters
are set as shown in the next section.
