Run in signal
The sensor has a build in controller for a stepper valve. The sensor pro-
vides both the analog output via the cable to control the valve. The lev-
el 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.
