NTERFACE
FAD-40PN instruments are state-of-the-art strain gauge load cell signal digitizers with Profinet interface. These
instruments are used for any type of process weighing and force measurement including tank and silo
weighing, dynamic weighing, check weighing, filling, tension /compression force measurement etc.
The GSDML file is available on a CD which is supplied together with the instrument and unter www.flintec.com.
7.1. Front View of FAD-40PN
There are 6 status LEDs on the front panel which indicate the operational instrument status (Refer to table
8.1).and the Profinet status. The setup switch on front panel of the instrument is used for Profinet addressing
without PC (Refer to chapter 5.6) and for diagnostics (Refer to chapter 12).
When the error LED is ON, the other two LED indicate the error type (Refer to chapter 11 for details).
Load cell connection, Profinet connection, power supply and serial interface terminals are located at the front of
the DIN rail mount instrument (See figure 8.1).
