Mode
This function outputs gate control signals that are derived from the compared setpoint
and weighing data of the materials from the hopper.
When the weight decreases past the setpoint, the gate control signal turns off.
When the weight increases past the setpoint, the gate control signal turns on.
The weighing mode in this function is bi-directional. Therefore, the comparison is
repeatable (reversible).
Concerning Parameters of the Function
Using loss-in-weigh of the comparison function
[5qf- 1] [1] Customer programmed control
[5qf- 3] [1] Loss-in-weigh
[Function] - [Function setting] - [Sequence] - [Basic]
Using the external control switch for normal batch and loss-in-weigh.
[5qf- 3] [2] External exchange
If the external switch is used, connect it to the I/O terminals. This
mode can use three gates.
[Function] - [Function setting] - [Sequence] - [Basic]
Checking whether there are remains from the last weighing operation in the hopper.
[5qf-55] Add final value and zero band
When the remains reach a weight that is under the final value +
zero band, the zero band signal is output.
[Function] - [Function setting] - [Sequence] - [Setpoint (Compared value)]
Using the external switch
[1n f-nn] [9] Supply switch control
nn: terminal number of the I/O.
[Function] - [Function setting] - [Control I/O] - [Input]
Checking whether there are remains from the last weighing operation in the hopper.
[5qf-56]
Add final value and full value
When the final value + full value is less than the remains (gross) in
the hopper, the full signal is output.
[Function] - [Function setting] - [Sequence] - [Setpoint (Compared value)]
Changing the accuracy of the comparison
[5qf-48] Averaging Eval time
The average time to criticize the weight.
[Function] - [Function setting] - [Sequence] - [Timer]
Using manual compensation
[1n f-nn] [10] Manual free fall compensation
[05 f-nn] [10]
Manual free fall compensation
nn: terminal number of the I/O.
The input to control free fall by an external PLC.
