4.7. Bus Addressing via Setup Switch
The bus addressing of FAD-40 instruments is done by the xFace software (Refer to chapter 5.3.1). The
alternative way for addressing is the setup switch on the front panel for addresses between 0 and 7 for RS-485,
Modbus RTU, Profibus and CANopen interfaces. This feature gives you the practical advantage for addressing
the instrument up to address 7 without requiring a PC connection.
For addressing via the setup switch, press this switch for 5 seconds. Then the status LEDs indicate the bus
address as shown in the table below. If the address is higher than 7 all LEDs are flashing. The address can be
changed by pressing the setup switch sequentially. To save and exit, press the setup switch for 5 seconds. To
return to normal operation without saving, wait 15 seconds without pressing the switch.

4.8. Back up Settings and Calibration Data
The parameter settings and the calibration coefficients can be saved to a backup file after reading these data
from the FAD-40 instrument. This backup file can be re-written to FAD-40 after opening it by xFace.
The backup feature gives a service advantage to FAD-40 instruments. We propose to burn these files to CD /
DVD and save this backup CD / DVD in the control cabinet additionally to a backup file on your PC.
Important note:
The previous parameter settings and calibration coefficients in FAD-40 will get lost after
loading a backup to the instrument.
