10.2.2 Start and Stop the Checkweighing
Follow one of the ways described below to start the checkweighing operation;
1. Function key: If you want to start the checkweighing operation by pressing key, program one of the
function key for smart operation (Refer to parameter 241, 242 and 243).
2. Digital input: The digital input-1 can be used to start the checkweighing operation.
3.
Serial interface: Transmit “Start SmartAPP” command via serial interface (Refer to parameter 111,
121, 131, 141 or 151).
4. Automatic checkweighing operation: If you will use the scale only for checkweighing and you prefer to
activate checkweighing operation automatically after loading, set the parameter 321 to automatic
operation.
To end the checkweighing operation;
1. Unload the scale or,
2. Disable the operation by pressing the function key, which is programmed as SmartAPP key or,
3. Reset the checkweighing with digital input-2 or,
4. Send the
“Stop SmartAPP” command via serial interface.
10.2.3 SmartAPP at Checkweighing
The SmartAPP at checkweighing announces if the load is in tolerances with backlight color, with bar graph on
the right side of the display and acoustically. The backlight color changes automatically to indicate the
checkweighing zones, to warn the operator.
The multicolor backlight feature provides operational comfort and reduces operator mistake. The weighing
speed increases because of operators’ faster and easy perception of colors.

Digital inputs and outputs
If one of the applications is selected, digital inputs and outputs are set according to the selected application
requirements automatically even they have been previously set to the different functions.
You can control your scale via these digital inputs and outputs. Non-used inputs and outputs of the application
can be programmed freely in the related parameter for any function or as a Remote IO of the PLC to control
them over fieldbus.
