The "customer programmed control mode" simply outputs the comparison results of
the setpoints and the displayed value.
The setpoint : A preset standard value to compare with the displayed value.
The comparison and output of the results are performed at each sampling time.
If this function is used, a PLC (programmable logic controller unit) is needed for batch
weighing on a hopper scale.
The power of the control I/O signal output is too small to drive a large valve directly.
Use relay output option ( OP-02 ) to drive them.
If the number of control I/O terminals is not enough, use the parallel I/O option ( OP-05 ).
Caution
Initial flow sequence and compensation sequence can not be used in the
"customer programmed control"
Advise
Automatic free fall compensation and Total function
If the start key is used, in the same as sequential mode, when three gates are closed, the
Eval timer has worked and the displayed value becomes stable, the batch finish signal
can be output.
The start key is not necessary to compare displayed values basically.
