8.2.2 Preset Weight Comparators Operation
The preset weight comparators are used to control peripheral
devices used in some form of process control. The number of
comparators used depends upon system needs.
For example, in a simple filling operation, a single comparator may
be used to open or close a gate which dumps material on the scale.
In a more complex application, more comparators may be used for
high speed/low speed filling.
The d out= (Digital Output) setup parameter selects how many
comparators are being used and the state of the output when the
scale weight is below the preset target or cutoff weight. The output
can be in one of two states: connected to the common pin on the
I/O connector or not connected to the common pin on the I/O
connector. When the scale weight is greater than or equal to the
cutoff weight, the output will change state.
