Motion Detection
This parameter defines the motion detection window which determines a stable weighing. If motion detection is
not required, this parameter can be disabled. The available motion detection window values are:
Weighing and Force Mode:
Disable ± 0.3e ± 0.5e (default setting) ± 1e ± 2e
Count Mode:
Disable ± 60 ± 100 (default setting) ± 200 ± 400
Power On Zero
This parameter enables automatic zeroing after powering on the instrument. The automatic zeroing is only
done if the total zero drift from the calibrated zero signal is in the defined zeroing window. This zeroing window
will be defined in the percentage of the scale capacity.
Disable (default setting) ± 2% ± 10%
To avoid unwanted zeroing at power on this parameter should be disabled or carefully set up in applications
like silo weighing, tank weighing and automatic weighing applications. If the weight is not within the power on
zeroing range, the instrument is powered on without zeroing (Not available in Count Mode).
Zeroing Range
Zeroing of the scale is performed if the difference between load cell signal value and unloaded load cell signal
value at the calibration is in the selected percentage of the scale capacity. Zeroing can be done by zeroing
command when the scale is stable. Zeroing can be done by zeroing command when the scale is stable.
The available zeroing ranges in the percentage of the scale capacity are:
Disable ± 2% (default setting) ± 20% ± 40%
Auto Zero Tracking
AZT automatically re-adjusts the scale to zero for compensating defined small deviations around the center of
zero. AZT only works within the defined zeroing range and stops working if this range is left.To avoid unwanted
zeroing this parameter should be disabled or carefully set up in applications like silo weighing, tank weighing
and automatic weighing applications (Not available in Count Mode). The available AZT window values are;
Disable (default setting) ± 0,5e ± 1e ± 3e
Tare
If this function is enabled, the weight is tared when the tare command is received. Additional conditions for
taring are positive gross weight and no motion. Multi-taring is possible with FAD-30 series (Not available in
Count Mode). Default setting: „Enable‟.
Save Tare at Power Off
If this function is enabled, the tare value is stored at power off and the instrument starts up in Net mode at
power on (Not available i
n Count Mode). Default setting: „Enable‟.
5.3.2. Serial Interface Setup
Data Format
This parameter defines the serial communication port data format for RS232 respective RS485. The available
data formats are:
Disable: Port will be disabled. Select “Disable” if this port is not used.
Continuous The data is transmitted continuously (for FAD-30 and FAD-30MB only).
Refer to chapter 5.8 for details.
BSI
(default setting for FAD30)): Communicates in BSI data format as a slave.
Refer to chapter 5.9 for details.
Modbus RTU
(default setting for FAD-30MB)): Modbus RTU communication (for FAD-30MB only).
Refer to chapter 5.11 for details
Note: xFace automatically connects to the instrument whatever the data format is. After xFace is disconnected,
the instrument returns to operate with the last saved data format.
Warning: Disable this interface if it is not used to increase the interfacing performance.
