7.4. Customer Programmed Control (Comparison Output)
The "customer programmed control" simply outputs the comparison result of the setpoints and weighing value.
The setpoint : It means the preset standard value to compare the weighing value. The comparison and output of the result are performed at every sampling time.
If the function is used, the PLC (programmable logic controller unit) needs for a batch weighing on the hopper scale.
The power of the control I/O signal output is too small to drive a large valve directly. Use option relay output (
If the number of the control I/O terminals is not enough, use option parallel I/O (
Caution
Approach sequence and compensation sequence can not use in the the "customer programmed control"
Advise
Automatic free fall compensation and Accumulation function
If the start key is used, in the same as sequential mode, when three gates are closed, criteria timer has worked and weighing value becomes stable, the batch finish signal can output.
The start key is not necessary to compare weighing value basically.
