to have the active pulse output of the flow sensor connected to
terminal G, pin 4.
•4 ... 20 mA signals from flow sensor or dew point sensors can be
looped through the G terminal pin 5 + 2. The e ternal device (PLC
or mA-meter) negative signal is connected to pin 1.
•Analog sensors are connectable to terminal I.

7 Configuration
The S320 is delivered with specific customer settings according to the
order.
In order to simplify the user interface not all settings but most of it are
accessible via the user interface, instead a PC software can be used.
This software is called S4C which can be downloaded from the company
web page.
To change certain or all settings by the user, S320 can be connected to
the PC via the USB interface. After starting S4C all device settings are
accessible.
All settings are stored permanently inside of the S320 and do not need
to be entered again, unless the user wants some changes. Some setting
for the dew point and flow sensor can also be done at the user
interfacer of S320.
